Educational psychology

From Wikipedia, the free encyclopedia
 
Educational psychology is the branch of psychology concerned with the scientific study of human learning. The study of learning processes, from both cognitive and behavioral perspectives, allows researchers to understand individual differences in intelligence, cognitive development, affect, motivation, self-regulation, and self-concept, as well as their role in learning. The field of educational psychology relies heavily on quantitative methods, including testing and measurement, to enhance educational activities related to instructional design, classroom management, and assessment, which serve to facilitate learning processes in various educational settings across the lifespan.
 
Educational psychology can in part be understood through its relationship with other disciplines. It is informed primarily by [psychology], bearing a relationship to that discipline analogous to the relationship between medicine and biology. It is also informed by neuroscience. Educational psychology in turn informs a wide range of specialities within educational studies, including instructional design, educational technology, curriculum development, organizational learning, special education, classroom management, and student motivation. Educational psychology both draws from and contributes to cognitive science and the learning sciences. In universities, departments of educational psychology are usually housed within faculties of education, possibly accounting for the lack of representation of educational psychology content in introductory psychology textbooks.

The field of educational psychology involves the study of memory, conceptual processes, and individual differences (via cognitive psychology) in conceptualizing new strategies for learning processes in humans. Educational psychology has been built upon theories of operant conditioning, functionalism, structuralism, constructivism, humanistic psychology, Gestalt psychology, and information processing.

Educational psychology has seen rapid growth and development as a profession in the last twenty years. School psychology began with the concept of intelligence testing leading to provisions for special education students, who could not follow the regular classroom curriculum in the early part of the 20th century. However, "school psychology" itself has built a fairly new profession based upon the practices and theories of several psychologists among many different fields. Educational psychologists are working side by side with psychiatrists, social workers, teachers, speech and language therapists, and counselors in attempt to understand the questions being raised when combining behavioral, cognitive, and social psychology in the classroom setting.

History

Early years

Educational psychology is a fairly new and growing field of study. Though it can date back as early as the days of Plato and Aristotle, it was not identified as a specific practice. It was unknown that everyday teaching and learning in which individuals had to think about individual differences, assessment, development, the nature of a subject being taught, problem solving, and transfer of learning was the beginning to the field of educational psychology. These topics are important to education and as a result it is important to understanding human cognition, learning, and social perception.

Plato and Aristotle

Educational psychology dates back to the time of Aristotle and Plato. Plato and Aristotle researched individual differences in the field of education, training of the body and the cultivation of psycho-motor skills, the formation of good character, the possibilities and limits of moral education. Some other educational topics they spoke about were the effects of music, poetry, and the other arts on the development of individual, role of teacher, and the relations between teacher and student. Plato saw knowledge as an innate ability, which evolves through experience and understanding of the world. Such a statement has evolved into a continuing argument of nature vs. nurture in understanding conditioning and learning today. Aristotle observed the phenomenon of "association." His four laws of association included succession, contiguity, similarity, and contrast. His studies examined recall and facilitated learning processes.

John Locke

John Locke was considered one of the most influential philosophers in post-renaissance Europe in about mid 1600s. Locke was called "Father of English Psychology". One of Locke's most important works was written in 1690, named An Essay Concerning Human Understanding. In this essay, he introduced the term "tabula rasa" meaning "blank slate." Locke explained that learning was primarily understood through experience only, and we were all born without knowledge.

He followed by contrasting Plato's theory of innate learning processes. Locke believed the mind was formed by experiences, not innate ideas. Locke introduced this idea as "empiricism," or the understanding that knowledge is only built on knowledge and experience.

In the late 1600s, John Locke advanced the hypothesis that people learn primarily from external forces. He believed that the mind was like a blank tablet (tabula rasa), and that successions of simple impressions give rise to complex ideas through association and reflection. Locke is credited with establishing "empiricism" as a criterion for testing the validity of knowledge, thus providing a conceptual framework for later development of experimental methodology in the natural and social sciences.

Before 1890

Philosophers of education such as Juan Vives, Johann Pestalozzi, Friedrich Fröbel, and Johann Herbart had examined, classified and judged the methods of education centuries before the beginnings of psychology in the late 1800s.

Juan Vives

Juan Vives (1493–1540) proposed induction as the method of study and believed in the direct observation and investigation of the study of nature. His studies focus of humanistic learning, which opposed scholasticism and was influenced by a variety of sources including philosophy, psychology, politics, religion, and history. He was one of the first to emphasize that the location of the school is important to learning. He suggested that the school should be located away from disturbing noises; the air quality should be good and there should be plenty of food for the students and teachers. Vives emphasized the importance of understanding individual differences of the students and suggested practice as an important tool for learning.

Vives introduced his educational ideas in his writing, "De anima et vita" in 1538. In this publication, Vives explores moral philosophy as a setting for his educational ideals; with this, he explains that the different parts of the soul (similar to that of Aristotle's ideas) are each responsible for different operations, which function distinctively. The first book covers the different "souls": "The Vegatative Soul;" this is the soul of nutrition, growth, and reproduction, "The Sensitive Soul," which involves the five external senses; "The Cogitative soul," which includes internal senses and cognitive facilities. The second book involves functions of the rational soul: mind, will, and memory. Lastly, the third book explains the analysis of emotions.

Johann Pestalozzi

Johann Pestalozzi (1746–1827), a Swiss educational reformer, emphasized the child rather than the content of the school. Pestalozzi fostered an educational reform backed by the idea that early education was crucial for children, and could be manageable for mothers. Eventually, this experience with early education would lead to a "wholesome person characterized by morality." Pestalozzi has been acknowledged for opening institutions for education, writing books for mother's teaching home education, and elementary books for students, mostly focusing on the kindergarten level. In his later years, he published teaching manuals and methods of teaching.

During the time of The Enlightenment, Pestalozzi's ideals introduced "educationalisation." This created the bridge between social issues and education by introducing the idea of social issues to be solved through education. Horlacher describes the most prominent example of this during The Enlightenment to be "improving agricultural production methods."

Johann Herbart

Johann Herbart (1776–1841) is considered the father of educational psychology. He believed that learning was influenced by interest in the subject and the teacher. He thought that teachers should consider the students' existing mental sets—what they already know—when presenting new information or material. Herbart came up with what are now known as the formal steps. The 5 steps that teachers should use are:
  1. Review material that has already been learned by the student
  2. Prepare the student for new material by giving them an overview of what they are learning next
  3. Present the new material.
  4. Relate the new material to the old material that has already been learned.
  5. Show how the student can apply the new material and show the material they will learn next.

1890–1920

There were three major figures in educational psychology in this period: William James, G. Stanley Hall, and John Dewey. These three men distinguished themselves in general psychology and educational psychology, which overlapped significantly at the end of the 19th century.

William James (1842–1910)

William James

The period of 1890–1920 is considered the golden era of educational psychology where aspirations of the new discipline rested on the application of the scientific methods of observation and experimentation to educational problems. From 1840 to 1920 37 million people immigrated to the United States. This created an expansion of elementary schools and secondary schools. The increase in immigration also provided educational psychologists the opportunity to use intelligence testing to screen immigrants at Ellis Island. Darwinism influenced the beliefs of the prominent educational psychologists. Even in the earliest years of the discipline, educational psychologists recognized the limitations of this new approach. The pioneering American psychologist William James commented that:
Psychology is a science, and teaching is an art; and sciences never generate arts directly out of themselves. An intermediate inventive mind must make that application, by using its originality".
James is the father of psychology in America but he also made contributions to educational psychology. In his famous series of lectures Talks to Teachers on Psychology, published in 1899, James defines education as "the organization of acquired habits of conduct and tendencies to behavior". He states that teachers should "train the pupil to behavior" so that he fits into the social and physical world. Teachers should also realize the importance of habit and instinct. They should present information that is clear and interesting and relate this new information and material to things the student already knows about. He also addresses important issues such as attention, memory, and association of ideas.

Alfred Binet

Alfred Binet published Mental Fatigue in 1898, in which he attempted to apply the experimental method to educational psychology. In this experimental method he advocated for two types of experiments, experiments done in the lab and experiments done in the classroom. In 1904 he was appointed the Minister of Public Education. This is when he began to look for a way to distinguish children with developmental disabilities. Binet strongly supported special education programs because he believed that "abnormality" could be cured. The Binet-Simon test was the first intelligence test and was the first to distinguish between "normal children" and those with developmental disabilities. Binet believed that it was important to study individual differences between age groups and children of the same age. He also believed that it was important for teachers to take into account individual students strengths and also the needs of the classroom as a whole when teaching and creating a good learning environment. He also believed that it was important to train teachers in observation so that they would be able to see individual differences among children and adjust the curriculum to the students. Binet also emphasized that practice of material was important. In 1916 Lewis Terman revised the Binet-Simon so that the average score was always 100. The test became known as the Stanford-Binet and was one of the most widely used tests of intelligence. Terman, unlike Binet, was interested in using intelligence test to identify gifted children who had high intelligence. In his longitudinal study of gifted children, who became known as the Termites, Terman found that gifted children become gifted adults.

Edward Thorndike

Edward Thorndike (1874–1949) supported the scientific movement in education. He based teaching practices on empirical evidence and measurement. Thorndike developed the theory of instrumental conditioning or the law of effect. The law of effect states that associations are strengthened when it is followed by something pleasing and associations are weakened when followed by something not pleasing. He also found that learning is done a little at a time or in increments, learning is an automatic process and all the principles of learning apply to all mammals. Thorndike's research with Robert Woodworth on the theory of transfer found that learning one subject will only influence your ability to learn another subject if the subjects are similar. This discovery led to less emphasis on learning the classics because they found that studying the classics does not contribute to overall general intelligence. Thorndike was one of the first to say that individual differences in cognitive tasks were due to how many stimulus response patterns a person had rather than a general intellectual ability. He contributed word dictionaries that were scientifically based to determine the words and definitions used. The dictionaries were the first to take into consideration the users maturity level. He also integrated pictures and easier pronunciation guide into each of the definitions. Thorndike contributed arithmetic books based on learning theory. He made all the problems more realistic and relevant to what was being studied, not just to improve the general intelligence. He developed tests that were standardized to measure performance in school related subjects. His biggest contribution to testing was the CAVD intelligence test which used a multidimensional approach to intelligence and the first to use a ratio scale. His later work was on programmed instruction, mastery learning and computer-based learning:
If, by a miracle of mechanical ingenuity, a book could be so arranged that only to him who had done what was directed on page one would page two become visible, and so on, much that now requires personal instruction could be managed by print.

John Dewey

John Dewey (1859–1952) had a major influence on the development of progressive education in the United States. He believed that the classroom should prepare children to be good citizens and facilitate creative intelligence. He pushed for the creation of practical classes that could be applied outside of a school setting. He also thought that education should be student-oriented, not subject-oriented. For Dewey, education was a social experience that helped bring together generations of people. He stated that students learn by doing. He believed in an active mind that was able to be educated through observation, problem solving and enquiry. In his 1910 book How We Think, he emphasizes that material should be provided in a way that is stimulating and interesting to the student since it encourages original thought and problem solving. He also stated that material should be relative to the student's own experience.
"The material furnished by way of information should be relevant to a question that is vital in the students own experience"

Jean Piaget

Jean Piaget (1896–1980) was one of the most powerful researchers in the area of developmental psychology during the 20th century. He developed the theory of cognitive development. The theory stated that intelligence developed in four different stages. The stages are the sensorimotor stage from birth to 2 years old, the preoperational state from 2 years old to 7 years old, the concrete operational stage from 7 years old to 10 years old, and formal operational stage from 11 years old and up. He also believed that learning was constrained to the child's cognitive development. Piaget influenced educational psychology because he was the first to believe that cognitive development was important and something that should be paid attention to in education. Most of the research on Piagetian theory was carried out by American educational psychologists.

1920–present

The number of people receiving a high school and college education increased dramatically from 1920 to 1960. Because very few jobs were available to teens coming out of eighth grade, there was an increase in high school attendance in the 1930s. The progressive movement in the United State took off at this time and led to the idea of progressive education. John Flanagan, an educational psychologist, developed tests for combat trainees and instructions in combat training. In 1954 the work of Kenneth Clark and his wife on the effects of segregation on black and white children was influential in the Supreme Court case Brown v. Board of Education. From the 1960s to present day, educational psychology has switched from a behaviorist perspective to a more cognitive based perspective because of the influence and development of cognitive psychology at this time.

Jerome Bruner

Jerome Bruner is notable for integrating Piaget's cognitive approaches into educational psychology. He advocated for discovery learning where teachers create a problem solving environment that allows the student to question, explore and experiment. In his book The Process of Education Bruner stated that the structure of the material and the cognitive abilities of the person are important in learning. He emphasized the importance of the subject matter. He also believed that how the subject was structured was important for the student's understanding of the subject and it is the goal of the teacher to structure the subject in a way that was easy for the student to understand. In the early 1960s Bruner went to Africa to teach math and science to school children, which influenced his view as schooling as a cultural institution. Bruner was also influential in the development of MACOS, Man a Course of Study, which was an educational program that combined anthropology and science. The program explored human evolution and social behavior. He also helped with the development of the head start program. He was interested in the influence of culture on education and looked at the impact of poverty on educational development.

Benjamin Bloom

Benjamin Bloom (1913–1999) spent over 50 years at the University of Chicago, where he worked in the department of education. He believed that all students can learn. He developed taxonomy of educational objectives. The objectives were divided into three domains: cognitive, affective, and psychomotor. The cognitive domain deals with how we think. It is divided into categories that are on a continuum from easiest to more complex. The categories are knowledge or recall, comprehension application, analysis, synthesis and evaluation. The affective domain deals with emotions and has 5 categories. The categories are receiving phenomenon, responding to that phenomenon, valuing, organization, and internalizing values. The psychomotor domain deals with the development of motor skills, movement and coordination and has 7 categories, that also goes from simplest to complex. The 7 categories of the psychomotor domain are perception, set, guided response, mechanism, complex overt response, adaptation, and origination. The taxonomy provided broad educational objectives that could be used to help expand the curriculum to match the ideas in the taxonomy. The taxonomy is considered to have a greater influence internationally than in the United States. Internationally, the taxonomy is used in every aspect of education from training of the teachers to the development of testing material. Bloom believed in communicating clear learning goals and promoting an active student. He thought that teachers should provide feedback to the students on their strengths and weaknesses. Bloom also did research on college students and their problem solving processes. He found that they differ in understanding the basis of the problem and the ideas in the problem. He also found that students differ in process of problem solving in their approach and attitude toward the problem.

Nathaniel Gage

Nathaniel Gage (1917 -2008) is an important figure in educational psychology as his research focused on improving teaching and understanding the processes involved in teaching. He edited the book Handbook of Research on Teaching (1963), which helped develop early research in teaching and educational psychology. Gage founded the Stanford Center for Research and Development in Teaching, which contributed research on teaching as well as influencing the education of important educational psychologists.

Perspectives

Behavioral

Applied behavior analysis, a research-based science utilizing behavioral principles of operant conditioning, is effective in a range of educational settings. For example, teachers can alter student behavior by systematically rewarding students who follow classroom rules with praise, stars, or tokens exchangeable for sundry items. Despite the demonstrated efficacy of awards in changing behavior, their use in education has been criticized by proponents of self-determination theory, who claim that praise and other rewards undermine intrinsic motivation. There is evidence that tangible rewards decrease intrinsic motivation in specific situations, such as when the student already has a high level of intrinsic motivation to perform the goal behavior. But the results showing detrimental effects are counterbalanced by evidence that, in other situations, such as when rewards are given for attaining a gradually increasing standard of performance, rewards enhance intrinsic motivation. Many effective therapies have been based on the principles of applied behavior analysis, including pivotal response therapy which is used to treat autism spectrum disorders.

Cognitive

Among current educational psychologists, the cognitive perspective is more widely held than the behavioral perspective, perhaps because it admits causally related mental constructs such as traits, beliefs, memories, motivations and emotions. Cognitive theories claim that memory structures determine how information is perceived, processed, stored, retrieved and forgotten. Among the memory structures theorized by cognitive psychologists are separate but linked visual and verbal systems described by Allan Paivio's dual coding theory. Educational psychologists have used dual coding theory and cognitive load theory to explain how people learn from multimedia presentations.

Three experiments reported by Krug, Davis and Glover demonstrated the advantage of delaying a 2nd reading of a text passage by one week (distributed) compared with no delay between readings (massed).

The spaced learning effect, a cognitive phenomenon strongly supported by psychological research, has broad applicability within education. For example, students have been found to perform better on a test of knowledge about a text passage when a second reading of the passage is delayed rather than immediate (see figure). Educational psychology research has confirmed the applicability to education of other findings from cognitive psychology, such as the benefits of using mnemonics for immediate and delayed retention of information.

Problem solving, according to prominent cognitive psychologists, is fundamental to learning. It resides as an important research topic in educational psychology. A student is thought to interpret a problem by assigning it to a schema retrieved from long-term memory. A problem students run into while reading is called "activation." This is when the student's representations of the text are present during working memory. This causes the student to read through the material without absorbing the information and being able to retain it. When working memory is absent from the reader's representations of the working memory they experience something called "deactivation." When deactivation occurs, the student has an understanding of the material and is able to retain information. If deactivation occurs during the first reading, the reader does not need to undergo deactivation in the second reading. The reader will only need to reread to get a "gist" of the text to spark their memory. When the problem is assigned to the wrong schema, the student's attention is subsequently directed away from features of the problem that are inconsistent with the assigned schema. The critical step of finding a mapping between the problem and a pre-existing schema is often cited as supporting the centrality of analogical thinking to problem solving.

Cognitive view of intelligence

An example of an item from a cognitive abilities test

Each person has an individual profile of characteristics, abilities and challenges that result from predisposition, learning and development. These manifest as individual differences in intelligence, creativity, cognitive style, motivation and the capacity to process information, communicate, and relate to others. The most prevalent disabilities found among school age children are attention deficit hyperactivity disorder (ADHD), learning disability, dyslexia, and speech disorder. Less common disabilities include intellectual disability, hearing impairment, cerebral palsy, epilepsy, and blindness.

Although theories of intelligence have been discussed by philosophers since Plato, intelligence testing is an invention of educational psychology, and is coincident with the development of that discipline. Continuing debates about the nature of intelligence revolve on whether intelligence can be characterized by a single factor known as general intelligence, multiple factors (e.g., Gardner's theory of multiple intelligences), or whether it can be measured at all. In practice, standardized instruments such as the Stanford-Binet IQ test and the WISC are widely used in economically developed countries to identify children in need of individualized educational treatment. Children classified as gifted are often provided with accelerated or enriched programs. Children with identified deficits may be provided with enhanced education in specific skills such as phonological awareness. In addition to basic abilities, the individual's personality traits are also important, with people higher in conscientiousness and hope attaining superior academic achievements, even after controlling for intelligence and past performance.

Developmental

Developmental psychology, and especially the psychology of cognitive development, opens a special perspective for educational psychology. This is so because education and the psychology of cognitive development converge on a number of crucial assumptions. First, the psychology of cognitive development defines human cognitive competence at successive phases of development. Education aims to help students acquire knowledge and develop skills which are compatible with their understanding and problem-solving capabilities at different ages. Thus, knowing the students' level on a developmental sequence provides information on the kind and level of knowledge they can assimilate, which, in turn, can be used as a frame for organizing the subject matter to be taught at different school grades. This is the reason why Piaget's theory of cognitive development was so influential for education, especially mathematics and science education. In the same direction, the neo-Piagetian theories of cognitive development suggest that in addition to the concerns above, sequencing of concepts and skills in teaching must take account of the processing and working memory capacities that characterize successive age levels.

Second, the psychology of cognitive development involves understanding how cognitive change takes place and recognizing the factors and processes which enable cognitive competence to develop. Education also capitalizes on cognitive change, because the construction of knowledge presupposes effective teaching methods that would move the student from a lower to a higher level of understanding. Mechanisms such as reflection on actual or mental actions vis-à-vis alternative solutions to problems, tagging new concepts or solutions to symbols that help one recall and mentally manipulate them are just a few examples of how mechanisms of cognitive development may be used to facilitate learning.

Finally, the psychology of cognitive development is concerned with individual differences in the organization of cognitive processes and abilities, in their rate of change, and in their mechanisms of change. The principles underlying intra- and inter-individual differences could be educationally useful, because knowing how students differ in regard to the various dimensions of cognitive development, such as processing and representational capacity, self-understanding and self-regulation, and the various domains of understanding, such as mathematical, scientific, or verbal abilities, would enable the teacher to cater for the needs of the different students so that no one is left behind.

Constructivist

Constructivism is a category of learning theory in which emphasis is placed on the agency and prior "knowing" and experience of the learner, and often on the social and cultural determinants of the learning process. Educational psychologists distinguish individual (or psychological) constructivism, identified with Piaget's theory of cognitive development, from social constructivism. A dominant influence on the latter type is Lev Vygotsky's work on sociocultural learning, describing how interactions with adults, more capable peers, and cognitive tools are internalized to form mental constructs. Elaborating on Vygotsky's theory, Jerome Bruner and other educational psychologists developed the important concept of instructional scaffolding, in which the social or information environment offers supports for learning that are gradually withdrawn as they become internalized.

Jean Piaget's Cognitive Development

Jean Piaget was interested in how an organism adapts to its environment. Piaget hypothesized that infants are born with a schema operating at birth that he called "reflexes". Piaget identified four stages in cognitive development. The four stages are sensorimotor stage, pre-operational stage, concrete operational stage and formal operational stage.

Conditioning and learning

An abacus provides concrete experiences for learning abstract concepts.

To understand the characteristics of learners in childhood, adolescence, adulthood, and old age, educational psychology develops and applies theories of human development. Often represented as stages through which people pass as they mature, developmental theories describe changes in mental abilities (cognition), social roles, moral reasoning, and beliefs about the nature of knowledge.

For example, educational psychologists have conducted research on the instructional applicability of Jean Piaget's theory of development, according to which children mature through four stages of cognitive capability. Piaget hypothesized that children are not capable of abstract logical thought until they are older than about 11 years, and therefore younger children need to be taught using concrete objects and examples. Researchers have found that transitions, such as from concrete to abstract logical thought, do not occur at the same time in all domains. A child may be able to think abstractly about mathematics, but remain limited to concrete thought when reasoning about human relationships. Perhaps Piaget's most enduring contribution is his insight that people actively construct their understanding through a self-regulatory process.

Piaget proposed a developmental theory of moral reasoning in which children progress from a naïve understanding of morality based on behavior and outcomes to a more advanced understanding based on intentions. Piaget's views of moral development were elaborated by Kohlberg into a stage theory of moral development. There is evidence that the moral reasoning described in stage theories is not sufficient to account for moral behavior. For example, other factors such as modeling (as described by the social cognitive theory of morality) are required to explain bullying.

Rudolf Steiner's model of child development interrelates physical, emotional, cognitive, and moral development in developmental stages similar to those later described by Piaget.

Developmental theories are sometimes presented not as shifts between qualitatively different stages, but as gradual increments on separate dimensions. Development of epistemological beliefs (beliefs about knowledge) have been described in terms of gradual changes in people's belief in: certainty and permanence of knowledge, fixedness of ability, and credibility of authorities such as teachers and experts. People develop more sophisticated beliefs about knowledge as they gain in education and maturity.

Motivation

Motivation is an internal state that activates, guides and sustains behavior. Motivation can have several impacting effects on how students learn and how they behave towards subject matter:
  • Provide direction towards goals
  • Enhance cognitive processing abilities and performance
  • Direct behavior toward particular goals
  • Lead to increased effort and energy
  • Increase initiation of and persistence in activities
Educational psychology research on motivation is concerned with the volition or will that students bring to a task, their level of interest and intrinsic motivation, the personally held goals that guide their behavior, and their belief about the causes of their success or failure. As intrinsic motivation deals with activities that act as their own rewards, extrinsic motivation deals with motivations that are brought on by consequences or punishments. A form of attribution theory developed by Bernard Weiner describes how students' beliefs about the causes of academic success or failure affect their emotions and motivations. For example, when students attribute failure to lack of ability, and ability is perceived as uncontrollable, they experience the emotions of shame and embarrassment and consequently decrease effort and show poorer performance. In contrast, when students attribute failure to lack of effort, and effort is perceived as controllable, they experience the emotion of guilt and consequently increase effort and show improved performance.

The self-determination theory (SDT) was developed by psychologists Edward Deci and Richard Ryan. SDT focuses on the importance of intrinsic and extrinsic motivation in driving human behavior and posits inherent growth and development tendencies. It emphasizes the degree to which an individual's behavior is self-motivated and self-determined. When applied to the realm of education, the self-determination theory is concerned primarily with promoting in students an interest in learning, a value of education, and a confidence in their own capacities and attributes.

Motivational theories also explain how learners' goals affect the way they engage with academic tasks. Those who have mastery goals strive to increase their ability and knowledge. Those who have performance approach goals strive for high grades and seek opportunities to demonstrate their abilities. Those who have performance avoidance goals are driven by fear of failure and avoid situations where their abilities are exposed. Research has found that mastery goals are associated with many positive outcomes such as persistence in the face of failure, preference for challenging tasks, creativity and intrinsic motivation. Performance avoidance goals are associated with negative outcomes such as poor concentration while studying, disorganized studying, less self-regulation, shallow information processing and test anxiety. Performance approach goals are associated with positive outcomes, and some negative outcomes such as an unwillingness to seek help and shallow information processing.

Locus of control is a salient factor in the successful academic performance of students. During the 1970s and '80s, Cassandra B. Whyte did significant educational research studying locus of control as related to the academic achievement of students pursuing higher education coursework. Much of her educational research and publications focused upon the theories of Julian B. Rotter in regard to the importance of internal control and successful academic performance. Whyte reported that individuals who perceive and believe that their hard work may lead to more successful academic outcomes, instead of depending on luck or fate, persist and achieve academically at a higher level. Therefore, it is important to provide education and counseling in this regard.

Technology

Bloom's taxonomy of educational objectives: categories in the cognitive domain
 
Instructional design, the systematic design of materials, activities and interactive environments for learning, is broadly informed by educational psychology theories and research. For example, in defining learning goals or objectives, instructional designers often use a taxonomy of educational objectives created by Benjamin Bloom and colleagues. Bloom also researched mastery learning, an instructional strategy in which learners only advance to a new learning objective after they have mastered its prerequisite objectives. Bloom discovered that a combination of mastery learning with one-to-one tutoring is highly effective, producing learning outcomes far exceeding those normally achieved in classroom instruction. Gagné, another psychologist, had earlier developed an influential method of task analysis in which a terminal learning goal is expanded into a hierarchy of learning objectives connected by prerequisite relationships. The following list of technological resources incorporate computer-aided instruction and intelligence for educational psychologists and their students:
Technology is essential to the field of educational psychology, not only for the psychologist themselves as far as testing, organization, and resources, but also for students. Educational Psychologists whom reside in the K- 12 setting focus the majority of their time with Special Education students. It has been found that students with disabilities learning through technology such as IPad applications and videos are more engaged and motivated to learn in the classroom setting. Liu et al. explain that learning-based technology allows for students to be more focused, and learning is more efficient with learning technologies. The authors explain that learning technology also allows for students with social- emotional disabilities to participate in distance learning.

Applications

Teaching

A class size experiment in the United States found that attending small classes for 3 or more years in the early grades increased high school graduation of students from low income families.
 
Research on classroom management and pedagogy is conducted to guide teaching practice and form a foundation for teacher education programs. The goals of classroom management are to create an environment conducive to learning and to develop students' self-management skills. More specifically, classroom management strives to create positive teacher–student and peer relationships, manage student groups to sustain on-task behavior, and use counseling and other psychological methods to aid students who present persistent psychosocial problems.

Introductory educational psychology is a commonly required area of study in most North American teacher education programs. When taught in that context, its content varies, but it typically emphasizes learning theories (especially cognitively oriented ones), issues about motivation, assessment of students' learning, and classroom management. A developing Wikibook about educational psychology gives more detail about the educational psychology topics that are typically presented in preservice teacher education.

Counseling

Training

In order to become an educational psychologist, students can complete an undergraduate degree in their choice. They then must go to graduate school to study education psychology, counseling psychology, and/ or school counseling. Most students today are also receiving their doctorate degrees in order to hold the "psychologist" title. Educational psychologists work in a variety of settings. Some work in university settings where they carry out research on the cognitive and social processes of human development, learning and education. Educational psychologists may also work as consultants in designing and creating educational materials, classroom programs and online courses.Educational psychologists who work in k–12 school settings (closely related are school psychologists in the US and Canada) are trained at the master's and doctoral levels. In addition to conducting assessments, school psychologists provide services such as academic and behavioral intervention, counseling, teacher consultation, and crisis intervention. However, school psychologists are generally more individual-oriented towards students.

Many colleges and high schools are starting to teach students how to teach students in the classroom. In colleges educational psychology is starting to be a general education requirement.

Employment outlook

Employment for psychologists in the United States is expected to grow faster than most occupations through the year 2014, with anticipated growth of 18–26%. One in four psychologists are employed in educational settings. In the United States, the median salary for psychologists in primary and secondary schools is US$58,360 as of May 2004. Colleges offer and allow someone to obtain a PHD in educational Psychology.

In recent decades the participation of women as professional researchers in North American educational psychology has risen dramatically.

Methods of research

Educational psychology, as much as any other field of psychology heavily relies on a balance of pure observation and quantitative methods in psychology. The study of education generally combines the studies of history, sociology, and ethics with theoretical approaches. Smeyers and Depaepe explain that historically, the study of education and child rearing have been associated with the interests of policymakers and practitioners within the educational field, however, the recent shift to sociology and psychology has opened the door for new findings in education as a social science. Now being its own academic discipline, educational psychology has proven to be helpful for social science researchers.

Quantitative research is the backing to most observable phenomena in psychology. This involves observing, creating, and understanding a distribution of data based upon the studies subject matter. Researchers use particular variables to interpret their data distributions from their research and employ statistics as a way of creating data tables and analyzing their data. Psychology has moved from the "common sense" reputations initially posed by Thomas Reid to the methodology approach comparing independent and dependent variables through natural observation, experiments, or combinations of the two. Though results are still, with statistical methods, objectively true based upon significance variables or p- values.

Psychometrics

From Wikipedia, the free encyclopedia

Psychometrics is a field of study concerned with the theory and technique of psychological measurement. As defined by the National Council on Measurement in Education (NCME), psychometrics refers to psychological measurement. Generally, it refers to the field in psychology and education that is devoted to testing, measurement, assessment, and related activities.

The field is concerned with the objective measurement of skills and knowledge, abilities, attitudes, personality traits, and educational achievement. Some psychometric researchers focus on the construction and validation of assessment instruments such as questionnaires, tests, raters' judgments, and personality tests. Others focus on research relating to measurement theory (e.g., item response theory; intraclass correlation).

Practitioners are described as psychometricians. Psychometricians usually possess a specific qualification, and most are psychologists with advanced graduate training. In addition to traditional academic institutions, many psychometricians work for the government or in human resources departments. Others specialize as learning and development professionals.

Historical foundation

Psychological testing has come from two streams of thought: the first, from Darwin, Galton, and Cattell on the measurement of individual differences, and the second, from Herbart, Weber, Fechner, and Wundt and their psychophysical measurements of a similar construct. The second set of individuals and their research is what has led to the development of experimental psychology, and standardized testing.

Victorian stream

Charles Darwin was the inspiration behind Sir Francis Galton who led to the creation of psychometrics. In 1859, Darwin published his book "The Origin of Species", which pertained to individual differences in animals. This book discussed how individual members in a species differ and how they possess characteristics that are more adaptive and successful or less adaptive and less successful. Those who are adaptive and successful are the ones that survive and give way to the next generation, who would be just as or more adaptive and successful. This idea, studied previously in animals, led to Galton's interest and study of human beings and how they differ one from another, and more importantly, how to measure those differences.

Galton wrote a book entitled "Hereditary Genius" about different characteristics that people possess and how those characteristics make them more "fit" than others. Today these differences, such as sensory and motor functioning (reaction time, visual acuity, and physical strength) are important domains of scientific psychology. Much of the early theoretical and applied work in psychometrics was undertaken in an attempt to measure intelligence. Galton, often referred to as "the father of psychometrics," devised and included mental tests among his anthropometric measures. James McKeen Cattell, who is considered a pioneer of psychometrics went on to extend Galton's work. Cattell also coined the term mental test, and is responsible for the research and knowledge which ultimately led to the development of modern tests. (Kaplan & Saccuzzo, 2010)

German stream

The origin of psychometrics also has connections to the related field of psychophysics. Around the same time that Darwin, Galton, and Cattell were making their discoveries, Herbart was also interested in "unlocking the mysteries of human consciousness" through the scientific method. (Kaplan & Saccuzzo, 2010) Herbart was responsible for creating mathematical models of the mind, which were influential in educational practices in years to come.

E.H. Weber built upon Herbart's work and tried to prove the existence of a psychological threshold, saying that a minimum stimulus was necessary to activate a sensory system. After Weber, G.T. Fechner expanded upon the knowledge he gleaned from Herbart and Weber, to devise the law that the strength of a sensation grows as the logarithm of the stimulus intensity. A follower of Weber and Fechner, Wilhelm Wundt is credited with founding the science of psychology. It is Wundt's influence that paved the way for others to develop psychological testing.

20th century

The psychometrician L. L. Thurstone, founder and first president of the Psychometric Society in 1936, developed and applied a theoretical approach to measurement referred to as the law of comparative judgment, an approach that has close connections to the psychophysical theory of Ernst Heinrich Weber and Gustav Fechner. In addition, Spearman and Thurstone both made important contributions to the theory and application of factor analysis, a statistical method developed and used extensively in psychometrics. In the late 1950s, Leopold Szondi made an historical and epistemological assessment of the impact of statistical thinking onto psychology during previous few decades: "in the last decades, the specifically psychological thinking has been almost completely suppressed and removed, and replaced by a statistical thinking. Precisely here we see the cancer of testology and testomania of today."

More recently, psychometric theory has been applied in the measurement of personality, attitudes, and beliefs, and academic achievement. Measurement of these unobservable phenomena is difficult, and much of the research and accumulated science in this discipline has been developed in an attempt to properly define and quantify such phenomena. Critics, including practitioners in the physical sciences and social activists, have argued that such definition and quantification is impossibly difficult, and that such measurements are often misused, such as with psychometric personality tests used in employment procedures:
"For example, an employer wanting someone for a role requiring consistent attention to repetitive detail will probably not want to give that job to someone who is very creative and gets bored easily."
Figures who made significant contributions to psychometrics include Karl Pearson, Henry F. Kaiser, Carl Brigham, L. L. Thurstone, Anne Anastasi, Georg Rasch, Eugene Galanter, Johnson O'Connor, Frederic M. Lord, Ledyard R Tucker, Arthur Jensen, and David Andrich.

Definition of measurement in the social sciences

The definition of measurement in the social sciences has a long history. A currently widespread definition, proposed by Stanley Smith Stevens (1946), is that measurement is "the assignment of numerals to objects or events according to some rule." This definition was introduced in the paper in which Stevens proposed four levels of measurement. Although widely adopted, this definition differs in important respects from the more classical definition of measurement adopted in the physical sciences, namely that scientific measurement entails "the estimation or discovery of the ratio of some magnitude of a quantitative attribute to a unit of the same attribute" (p. 358)

Indeed, Stevens's definition of measurement was put forward in response to the British Ferguson Committee, whose chair, A. Ferguson, was a physicist. The committee was appointed in 1932 by the British Association for the Advancement of Science to investigate the possibility of quantitatively estimating sensory events. Although its chair and other members were physicists, the committee also included several psychologists. The committee's report highlighted the importance of the definition of measurement. While Stevens's response was to propose a new definition, which has had considerable influence in the field, this was by no means the only response to the report. Another, notably different, response was to accept the classical definition, as reflected in the following statement:
Measurement in psychology and physics are in no sense different. Physicists can measure when they can find the operations by which they may meet the necessary criteria; psychologists have but to do the same. They need not worry about the mysterious differences between the meaning of measurement in the two sciences. (Reese, 1943, p. 49)
These divergent responses are reflected in alternative approaches to measurement. For example, methods based on covariance matrices are typically employed on the premise that numbers, such as raw scores derived from assessments, are measurements. Such approaches implicitly entail Stevens's definition of measurement, which requires only that numbers are assigned according to some rule. The main research task, then, is generally considered to be the discovery of associations between scores, and of factors posited to underlie such associations.

On the other hand, when measurement models such as the Rasch model are employed, numbers are not assigned based on a rule. Instead, in keeping with Reese's statement above, specific criteria for measurement are stated, and the goal is to construct procedures or operations that provide data that meet the relevant criteria. Measurements are estimated based on the models, and tests are conducted to ascertain whether the relevant criteria have been met.

Instruments and procedures

The firstpsychometric instruments were designed to measure the concept of intelligence. One historical approach involved the Stanford-Binet IQ test, developed originally by the French psychologist Alfred Binet. Intelligence tests are useful tools for various purposes. An alternative conception of intelligence is that cognitive capacities within individuals are a manifestation of a general component, or general intelligence factor, as well as cognitive capacity specific to a given domain.

Psychometrics is applied widely in educational assessment to measure abilities in domains such as reading, writing, and mathematics. The main approaches in applying tests in these domains have been classical test theory and the more recent Item Response Theory and Rasch measurement models. These latter approaches permit joint scaling of persons and assessment items, which provides a basis for mapping of developmental continua by allowing descriptions of the skills displayed at various points along a continuum.

Another major focus in psychometrics has been on personality testing. There have been a range of theoretical approaches to conceptualizing and measuring personality. Some of the better known instruments include the Minnesota Multiphasic Personality Inventory, the Five-Factor Model (or "Big 5") and tools such as Personality and Preference Inventory and the Myers-Briggs Type Indicator. Attitudes have also been studied extensively using psychometric approaches. A common method in the measurement of attitudes is the use of the Likert scale. An alternative method involves the application of unfolding measurement models, the most general being the Hyperbolic Cosine Model (Andrich & Luo, 1993).

Theoretical approaches

Psychometricians have developed a number of different measurement theories. These include classical test theory (CTT) and item response theory (IRT). An approach which seems mathematically to be similar to IRT but also quite distinctive, in terms of its origins and features, is represented by the Rasch model for measurement. The development of the Rasch model, and the broader class of models to which it belongs, was explicitly founded on requirements of measurement in the physical sciences.

Psychometricians have also developed methods for working with large matrices of correlations and covariances. Techniques in this general tradition include: factor analysis, a method of determining the underlying dimensions of data; multidimensional scaling, a method for finding a simple representation for data with a large number of latent dimensions; and data clustering, an approach to finding objects that are like each other. All these multivariate descriptive methods try to distill large amounts of data into simpler structures. More recently, structural equation modeling and path analysis represent more sophisticated approaches to working with large covariance matrices. These methods allow statistically sophisticated models to be fitted to data and tested to determine if they are adequate fits.

One of the main deficiencies in various factor analyses is a lack of consensus in cutting points for determining the number of latent factors. A usual procedure is to stop factoring when eigenvalues drop below one because the original sphere shrinks. The lack of the cutting points concerns other multivariate methods, also.

Key concepts

Key concepts in classical test theory are reliability and validity. A reliable measure is one that measures a construct consistently across time, individuals, and situations. A valid measure is one that measures what it is intended to measure. Reliability is necessary, but not sufficient, for validity.

Both reliability and validity can be assessed statistically. Consistency over repeated measures of the same test can be assessed with the Pearson correlation coefficient, and is often called test-retest reliability. Similarly, the equivalence of different versions of the same measure can be indexed by a Pearson correlation, and is called equivalent forms reliability or a similar term.

Internal consistency, which addresses the homogeneity of a single test form, may be assessed by correlating performance on two halves of a test, which is termed split-half reliability; the value of this Pearson product-moment correlation coefficient for two half-tests is adjusted with the Spearman–Brown prediction formula to correspond to the correlation between two full-length tests. Perhaps the most commonly used index of reliability is Cronbach's α, which is equivalent to the mean of all possible split-half coefficients. Other approaches include the intra-class correlation, which is the ratio of variance of measurements of a given target to the variance of all targets.

There are a number of different forms of validity. Criterion-related validity can be assessed by correlating a measure with a criterion measure theoretically expected to be related. When the criterion measure is collected at the same time as the measure being validated the goal is to establish concurrent validity; when the criterion is collected later the goal is to establish predictive validity. A measure has construct validity if it is related to measures of other constructs as required by theory.  Content validity is a demonstration that the items of a test do an adequate job of covering the domain being measured. In a personnel selection example, test content is based on a defined statement or set of statements of knowledge, skill, ability, or other characteristics obtained from a job analysis.

Item response theory models the relationship between latent traits and responses to test items. Among other advantages, IRT provides a basis for obtaining an estimate of the location of a test-taker on a given latent trait as well as the standard error of measurement of that location. For example, a university student's knowledge of history can be deduced from his or her score on a university test and then be compared reliably with a high school student's knowledge deduced from a less difficult test. Scores derived by classical test theory do not have this characteristic, and assessment of actual ability (rather than ability relative to other test-takers) must be assessed by comparing scores to those of a "norm group" randomly selected from the population. In fact, all measures derived from classical test theory are dependent on the sample tested, while, in principle, those derived from item response theory are not.

Many psychometricians are also concerned with finding and eliminating test bias from their psychological tests. Test bias is a form of systematic (i.e., non-random) error which leads to examinees from one demographic group having an unwarranted advantage over examinees from another demographic group. According to leading experts, test bias may cause differences in average scores across demographic groups, but differences in group scores are not sufficient evidence that test bias is actually present because the test could be measuring real differences among groups. Psychometricians use sophisticated scientific methods to search for test bias and eliminate it. Research shows that it is usually impossible for people reading a test item to accurately determine whether it is biased or not.

Standards of quality

The considerations of validity and reliability typically are viewed as essential elements for determining the quality of any test. However, professional and practitioner associations frequently have placed these concerns within broader contexts when developing standards and making overall judgments about the quality of any test as a whole within a given context. A consideration of concern in many applied research settings is whether or not the metric of a given psychological inventory is meaningful or arbitrary.

Testing standards

In 2014, the American Educational Research Association (AERA), American Psychological Association (APA), and National Council on Measurement in Education (NCME) published a revision of the Standards for Educational and Psychological Testing, which describes standards for test development, evaluation, and use. The Standards cover essential topics in testing including validity, reliability/errors of measurement, and fairness in testing. The book also establishes standards related to testing operations including test design and development, scores, scales, norms, score linking, cut scores, test administration, scoring, reporting, score interpretation, test documentation, and rights and responsibilities of test takers and test users. Finally, the Standards cover topics related to testing applications, including psychological testing and assessment, workplace testing and credentialing, educational testing and assessment, and testing in program evaluation and public policy.

Evaluation standards

In the field of evaluation, and in particular educational evaluation, the Joint Committee on Standards for Educational Evaluation has published three sets of standards for evaluations. The Personnel Evaluation Standards was published in 1988, The Program Evaluation Standards (2nd edition) was published in 1994, and The Student Evaluation Standards was published in 2003.

Each publication presents and elaborates a set of standards for use in a variety of educational settings. The standards provide guidelines for designing, implementing, assessing and improving the identified form of evaluation. Each of the standards has been placed in one of four fundamental categories to promote educational evaluations that are proper, useful, feasible, and accurate. In these sets of standards, validity and reliability considerations are covered under the accuracy topic. For example, the student accuracy standards help ensure that student evaluations will provide sound, accurate, and credible information about student learning and performance.

Non-human: animals and machines

Psychometrics addresses human abilities, attitudes, traits and educational evolution. Notably, the study of behavior, mental processes and abilities of non-human animals is usually addressed by comparative psychology, or with a continuum between non-human animals and the rest of animals by evolutionary psychology. Nonetheless there are some advocators for a more gradual transition between the approach taken for humans and the approach taken for (non-human) animals.

The evaluation of abilities, traits and learning evolution of machines has been mostly unrelated to the case of humans and non-human animals, with specific approaches in the area of artificial intelligence. A more integrated approach, under the name of universal psychometrics, has also been proposed.
