Government by algorithm

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Government_by_algorithm

Government by algorithm
(also known as algorithmic regulation, regulation by algorithms, algorithmic governance, algocratic governance, algorithmic legal order or algocracy) is an alternative form of government or social ordering where the usage of computer algorithms is applied to regulations, law enforcement, and generally any aspect of everyday life such as transportation or land registration. The term "government by algorithm" has appeared in academic literature as an alternative for "algorithmic governance" in 2013. A related term, algorithmic regulation, is defined as setting the standard, monitoring and modifying behaviour by means of computational algorithms – automation of judiciary is in its scope. In the context of blockchain, it is also known as blockchain governance.

Government by algorithm raises new challenges that are not captured in the e-government literature and the practice of public administration. Some sources equate cyberocracy, which is a hypothetical form of government that rules by the effective use of information, with algorithmic governance, although algorithms are not the only means of processing information. Nello Cristianini and Teresa Scantamburlo argued that the combination of a human society and certain regulation algorithms (such as reputation-based scoring) forms a social machine.

History

"Blockchain and the future of governance. Let's overcome the hype and understand what can be done." with Andrea Bauer, Boris Moshkovits und Shermin Voshmgir at re:publica

In 1962, the director of the Institute for Information Transmission Problems of the Russian Academy of Sciences in Moscow (later Kharkevich Institute), Alexander Kharkevich, published an article in the journal "Communist" about a computer network for processing information and control of the economy. In fact, he proposed to make a network like the modern Internet for the needs of algorithmic governance (Project OGAS). This created a serious concern among CIA analysts. In particular, Arthur M. Schlesinger Jr. warned that "by 1970 the USSR may have a radically new production technology, involving total enterprises or complexes of industries, managed by closed-loop, feedback control employing self-teaching computers".

Between 1971 and 1973, the Chilean government carried out Project Cybersyn during the presidency of Salvador Allende. This project was aimed at constructing a distributed decision support system to improve the management of the national economy. Elements of the project were used in 1972 to successfully overcome the traffic collapse caused by a CIA-sponsored strike of forty thousand truck drivers.

Also in the 1960s and 1970s, Herbert A. Simon championed expert systems as tools for rationalization and evaluation of administrative behavior. The automation of rule-based processes was an ambition of tax agencies over many decades resulting in varying success. Early work from this period includes Thorne McCarty's influential TAXMAN project in the US and Ronald Stamper's LEGOL project in the UK. In 1993, the computer scientist Paul Cockshott from the University of Glasgow and the economist Allin Cottrell from the Wake Forest University published the book Towards a New Socialism, where they claim to demonstrate the possibility of a democratically planned economy built on modern computer technology. The Honourable Justice Michael Kirby published a paper in 1998, where he expressed optimism that the then-available computer technologies such as legal expert system could evolve to computer systems, which will strongly affect the practice of courts. In 2006, attorney Lawrence Lessig, known for the slogan "Code is law", wrote:

[T]he invisible hand of cyberspace is building an architecture that is quite the opposite of its architecture at its birth. This invisible hand, pushed by government and by commerce, is constructing an architecture that will perfect control and make highly efficient regulation possible

Since the 2000s, algorithms have been designed and used to automatically analyze surveillance videos.

In his 2006's book Virtual Migration, A. Aneesh developed the concept of algocracy — information technologies constrain human participation in public decision making. Aneesh differentiated algocratic systems from bureaucratic systems (legal-rational regulation) as well as market-based systems (price-based regulation).

In 2013, algorithmic regulation was coined by Tim O'Reilly, founder and CEO of O'Reilly Media Inc.:

Sometimes the "rules" aren't really even rules. Gordon Bruce, the former CIO of the city of Honolulu, explained to me that when he entered government from the private sector and tried to make changes, he was told, "That's against the law." His reply was "OK. Show me the law." "Well, it isn't really a law. It's a regulation." "OK. Show me the regulation." "Well, it isn't really a regulation. It's a policy that was put in place by Mr. Somebody twenty years ago." "Great. We can change that!" [...] Laws should specify goals, rights, outcomes, authorities, and limits. If specified broadly, those laws can stand the test of time. Regulations, which specify how to execute those laws in much more detail, should be regarded in much the same way that programmers regard their code and algorithms, that is, as a constantly updated toolset to achieve the outcomes specified in the laws. [...] It's time for government to enter the age of big data. Algorithmic regulation is an idea whose time has come.

In 2017, Ukraine's Ministry of Justice ran experimental government auctions using blockchain technology to ensure transparency and hinder corruption in governmental transactions. "Government by Algorithm?" was the central theme introduced at Data for Policy 2017 conference held on 6–7 September 2017 in London.

Examples

Smart cities

Architecture of the IoT for home care systems

A smart city is an urban area where collected surveillance data is used to improve various operations. Increase in computational power allows more automated decision making and replacement of public agencies by algorithmic governance. In particular, the combined use of artificial intelligence and blockchains for IoT may lead to the creation of sustainable smart city ecosystems. Intelligent street lighting in Glasgow is an example of successful government application of AI algorithms. A study of smart city initiatives in the US shows that it requires public sector as a main organizer and coordinator, the private sector as a technology and infrastructure provider, and universities as expertise contributors.

The cryptocurrency millionaire Jeffrey Berns proposed the operation of local governments in Nevada by tech firms in 2021. Berns bought 67,000 acres (271 km2) in Nevada's rural Storey County (population 4,104) for $170,000,000 (£121,000,000) in 2018 in order to develop a smart city with more than 36,000 residents that could generate an annual output of $4,600,000,000. Cryptocurrency will be allowed for payments. Blockchains, Inc. "Innovation Zone" was canceled in September 2021 after it failed to secure enough water for the planned 36,000 residents, through water imports from a site located 100 miles away in the neighboring Washoe County. Similar water pipeline proposed in 2007 was estimated to cost $100 million and to would have taken about 10 years to develop. With additional water rights purchased from Tahoe Reno Industrial General Improvement District, "Innovation Zone" would have acquired enough water for about 15,400 homes - meaning that it would have barely covered its planned 15,000 dwelling units, leaving nothing for the rest of the projected city and its 22 million square-feet of industrial development.

In Saudi Arabia, the planners of The Line assert that it will be monitored by AI to improve life by using data and predictive modeling.

Reputation systems

Model of cybernetic thinking about organisation. On the one hand in reality a system is determined. On the other hand, cybernetic factory can be modeled as a control system.

Tim O'Reilly suggested that data sources and reputation systems combined in algorithmic regulation can outperform traditional regulations. For instance, once taxi-drivers are rated by passengers, the quality of their services will improve automatically and "drivers who provide poor service are eliminated". O'Reilly's suggestion is based on control-theoreric concept of feed-back loopimprovements and disimprovements of reputation enforce desired behavior. The usage of feed-loops for the management of social systems is already been suggested in management cybernetics by Stafford Beer before.

These connections are explored by Nello Cristianini and Teresa Scantamburlo, where the reputation-credit scoring system is modeled as an incentive given to the citizens and computed by a social machine, so that rational agents would be motivated to increase their score by adapting their behaviour. Several ethical aspects of that technology are still being discussed.

China's Social Credit System was said to be a mass surveillance effort with a centralized numerical score for each citizen given for their actions, though newer reports say that this is a widespread misconception.

Smart contracts

Smart contracts, cryptocurrencies, and decentralized autonomous organization are mentioned as means to replace traditional ways of governance. Cryptocurrencies are currencies, which are enabled by algorithms without a governmental central bank. Central bank digital currency often employs similar technology, but is differentiated from the fact that it does use a central bank. It is soon to be employed by major unions and governments such as the European Union and China. Smart contracts are self-executable contracts, whose objectives are the reduction of need in trusted governmental intermediators, arbitrations and enforcement costs. A decentralized autonomous organization is an organization represented by smart contracts that is transparent, controlled by shareholders and not influenced by a central government. Smart contracts have been discussed for use in such applications as use in (temporary) employment contracts and automatic transfership of funds and property (i.e. inheritance, upon registration of a death certificate). Some countries such as Georgia and Sweden have already launched blockchain programs focusing on property (land titles and real estate ownership) Ukraine is also looking at other areas too such as state registers.

Algorithms in government agencies

According to a study of Stanford University, 45% of the studied US federal agencies have experimented with AI and related machine learning (ML) tools up to 2020. US federal agencies counted the number of artificial intelligence applications, which are listed below. 53% of these applications were produced by in-house experts. Commercial providers of residual applications include Palantir Technologies.

Agency Name Number of Use Cases
Office of Justice Programs 12
Securities and Exchange Commission 10
National Aeronautics and Space Administration 9
Food and Drug Administration 8
United States Geological Survey 8
United States Postal Service 8
Social Security Administration 7
United States Patent and Trademark Office 6
Bureau of Labor Statistics 5
U.S. Customs and Border Protection 4

In 2012, NOPD started a collaboration with Palantir Technologies in the field of predictive policing. Besides Palantir's Gotham software, other similar (numerical analysis software) used by police agencies (such as the NCRIC) include SAS.

In the fight against money laundering, FinCEN employs the FinCEN Artificial Intelligence System (FAIS) since 1995.

National health administration entities and organisations such as AHIMA (American Health Information Management Association) hold medical records. Medical records serve as the central repository for planning patient care and documenting communication among patient and health care provider and professionals contributing to the patient's care. In the EU, work is ongoing on a European Health Data Space which supports the use of health data.

US Department of Homeland Security has employed the software ATLAS, which run on Amazon Cloud. It scanned more than 16.5 million of records of naturalized Americans and flagged approximately 124,000 of them for manual analysis and review by USCIS officers regarding denaturalization. There were flagged due to potential fraud, public safety and national security issues. Some of the scanned data came from Terrorist Screening Database and National Crime Information Center.

The NarxCare is a US software, which combines data from the prescription registries of various U.S. states and uses machine learning to generate various three-digit "risk scores" for prescriptions of medications and an overall "Overdose Risk Score", collectively referred to as Narx Scores, in a process that potentially includes EMS and criminal justice data as well as court records.

In Estonia, artificial intelligence is used in its e-government to make it more automated and seamless. A virtual assistant will guide citizens through any interactions they have with the government. Automated and proactive services "push" services to citizens at key events of their lives (including births, bereavements, unemployment, ...). One example is the automated registering of babies when they are born. Estonia's X-Road system will also be rebuilt to include even more privacy control and accountability into the way the government uses citizen's data.

In Costa Rica, the possible digitalization of public procurement activities (i.e. tenders for public works, ...) has been investigated. The paper discussing this possibility mentions that the use of ICT in procurement has several benefits such as increasing transparency, facilitating digital access to public tenders, reducing direct interaction between procurement officials and companies at moments of high integrity risk, increasing outreach and competition, and easier detection of irregularities.

Besides using e-tenders for regular public works (construction of buildings, roads, ...), e-tenders can also be used for reforestation projects and other carbon sink restoration projects. Carbon sink restoration projects may be part of the nationally determined contributions plans in order to reach the national Paris agreement goals

Government procurement audit software can also be used. Audits are performed in some countries after subsidies have been received.

Some government agencies provide track and trace systems for services they offer. An example is track and trace for applications done by citizens (i.e. driving license procurement).

Some government services use issue tracking system to keep track of ongoing issues.

Justice by algorithm

Judges' decisions in Australia are supported by the "Split Up" software in case of determining the percentage of a split after a divorce. COMPAS software is used in USA to assess the risk of recidivism in courts. According to the statement of Beijing Internet Court, China is the first country to create an internet court or cyber court. The Chinese AI judge is a virtual recreation of an actual female judge. She "will help the court's judges complete repetitive basic work, including litigation reception, thus enabling professional practitioners to focus better on their trial work". Also Estonia plans to employ artificial intelligence to decide small-claim cases of less than €7,000.

Lawbots can perform tasks that are typically done by paralegals or young associates at law firms. One such technology used by US law firms to assist in legal research is from ROSS Intelligence, and others vary in sophistication and dependence on scripted algorithms. Another legal technology chatbot application is DoNotPay.

Algorithms in education

Due to the COVID-19 pandemic in 2020, in-person final exams were impossible for thousands of students. The public high school Westminster High employed algorithms to assign grades. UK's Department for Education also employed a statistical calculus to assign final grades in A-levels, due to the pandemic.

Besides use in grading, software systems like AI were used in preparation for college entrance exams.

AI teaching assistants are being developed and used for education (e.g., Georgia Tech's Jill Watson) and there is also an ongoing debate on whether perhaps teachers can be entirely replaced by AI systems (e.g., in homeschooling).

AI politicians

In 2018, an activist named Michihito Matsuda ran for mayor in the Tama city area of Tokyo as a human proxy for an artificial intelligence program. While election posters and campaign material used the term robot, and displayed stock images of a feminine android, the "AI mayor" was in fact a machine learning algorithm trained using Tama city datasets. The project was backed by high-profile executives Tetsuzo Matsumoto of Softbank and Norio Murakami of Google. Michihito Matsuda came third in the election, being defeated by Hiroyuki Abe. Organisers claimed that the 'AI mayor' was programmed to analyze citizen petitions put forward to the city council in a more 'fair and balanced' way than human politicians.

In 2018, Cesar Hidalgo presented the idea of augumented democracy. In an augumented democracy, legislation is done by digital twins of every single person.

In 2019, AI-powered messenger chatbot SAM participated in the discussions on social media connected to an electoral race in New Zealand. The creator of SAM, Nick Gerritsen, believes SAM will be advanced enough to run as a candidate by late 2020, when New Zealand has its next general election.

In 2022, the chatbot "Leader Lars" or "Leder Lars" was nominated for The Synthetic Party to run in the 2022 Danish parliamentary election, and was built by the artist collective Computer Lars. Leader Lars differed from earlier virtual politicians by leading a political party and by not pretending to be an objective candidate. This chatbot engaged in critical discussions on politics with users from around the world.

In 2023, In the Japanese town of Manazuru, a mayoral candidate called "AI Mayer" hopes to be the first AI-powered officeholder in Japan in November 2023. This candidacy is said to be supported by a group led by Michihito Matsuda 

In the 2024 United Kingdom general election, a businessman named Steve Endacott ran for the constituency of Brighton Pavilion as an AI avatar named "AI Steve", saying that constituents could interact with AI Steve to shape policy. Endacott stated that he would only attend Parliament to vote based on policies which had garnered at least 50% support. AI Steve placed last with 179 votes.

Management of infection

A schematic of app-based COVID-19 contact tracing

In February 2020, China launched a mobile app to deal with the Coronavirus outbreak called "close-contact-detector". Users are asked to enter their name and ID number. The app is able to detect "close contact" using surveillance data (i.e. using public transport records, including trains and flights) and therefore a potential risk of infection. Every user can also check the status of three other users. To make this inquiry users scan a Quick Response (QR) code on their smartphones using apps like Alipay or WeChat. The close contact detector can be accessed via popular mobile apps including Alipay. If a potential risk is detected, the app not only recommends self-quarantine, it also alerts local health officials.

Alipay also has the Alipay Health Code which is used to keep citizens safe. This system generates a QR code in one of three colors (green, yellow, or red) after users fill in a form on Alipay with personal details. A green code enables the holder to move around unrestricted. A yellow code requires the user to stay at home for seven days and red means a two-week quarantine. In some cities such as Hangzhou, it has become nearly impossible to get around without showing one's Alipay code.

In Cannes, France, monitoring software has been used on footage shot by CCTV cameras, allowing to monitor their compliance to local social distancing and mask wearing during the COVID-19 pandemic. The system does not store identifying data, but rather allows to alert city authorities and police where breaches of the mask and mask wearing rules are spotted (allowing fining to be carried out where needed). The algorithms used by the monitoring software can be incorporated into existing surveillance systems in public spaces (hospitals, stations, airports, shopping centres, ...) 

Cellphone data is used to locate infected patients in South Korea, Taiwan, Singapore and other countries. In March 2020, the Israeli government enabled security agencies to track mobile phone data of people supposed to have coronavirus. The measure was taken to enforce quarantine and protect those who may come into contact with infected citizens. Also in March 2020, Deutsche Telekom shared private cellphone data with the federal government agency, Robert Koch Institute, in order to research and prevent the spread of the virus. Russia deployed facial recognition technology to detect quarantine breakers. Italian regional health commissioner Giulio Gallera said that "40% of people are continuing to move around anyway", as he has been informed by mobile phone operators. In USA, Europe and UK, Palantir Technologies is taken in charge to provide COVID-19 tracking services.

Prevention and management of environmental disasters

Tsunamis can be detected by Tsunami warning systems. They can make use of AI. Floodings can also be detected using AI systems. Wildfires can be predicted using AI systems. Wildfire detection is possible by AI systems (i.e. through satellite data, aerial imagery, and GPS phone personnel position) and can help in the evacuation of people during wildfires, to investigate how householders responded in wildfires and spotting wildfire in real time using computer vision. Earthquake detection systems are now improving alongside the development of AI technology through measuring seismic data and implementing complex algorithms to improve detection and prediction rates. Earthquake monitoring, phase picking, and seismic signal detection have developed through AI algorithms of deep-learning, analysis, and computational models. Locust breeding areas can be approximated using machine learning, which could help to stop locust swarms in an early phase.

Reception

Benefits

Algorithmic regulation is supposed to be a system of governance where more exact data, collected from citizens via their smart devices and computers, is used to more efficiently organize human life as a collective. As Deloitte estimated in 2017, automation of US government work could save 96.7 million federal hours annually, with a potential savings of $3.3 billion; at the high end, this rises to 1.2 billion hours and potential annual savings of $41.1 billion.

Criticism

There are potential risks associated with the use of algorithms in government. Those include algorithms becoming susceptible to bias, a lack of transparency in how an algorithm may make decisions, and the accountability for any such decisions. According to a 2016's book Weapons of Math Destruction, algorithms and big data are suspected to increase inequality due to opacity, scale and damage.

There is also a serious concern that gaming by the regulated parties might occur, once more transparency is brought into the decision making by algorithmic governance, regulated parties might try to manipulate their outcome in own favor and even use adversarial machine learning. According to Harari, the conflict between democracy and dictatorship is seen as a conflict of two different data-processing systems—AI and algorithms may swing the advantage toward the latter by processing enormous amounts of information centrally.

In 2018, the Netherlands employed an algorithmic system SyRI (Systeem Risico Indicatie) to detect citizens perceived being high risk for committing welfare fraud, which quietly flagged thousands of people to investigators. This caused a public protest. The district court of Hague shut down SyRI referencing Article 8 of the European Convention on Human Rights (ECHR).

The contributors of the 2019 documentary iHuman expressed apprehension of "infinitely stable dictatorships" created by government AI.

Due to public criticism, the Australian government announced the suspension of Robodebt scheme key functions in 2019, and a review of all debts raised using the programme.

In 2020, algorithms assigning exam grades to students in the UK sparked open protest under the banner "Fuck the algorithm." This protest was successful and the grades were taken back.

In 2020, the US government software ATLAS, which run on Amazon Cloud, sparked uproar from activists and Amazon's own employees.

In 2021, Eticas Foundation has launched a database of governmental algorithms called Observatory of Algorithms with Social Impact (OASI).

Algorithmic bias and transparency

An initial approach towards transparency included the open-sourcing of algorithms. Software code can be looked into and improvements can be proposed through source-code-hosting facilities.

Public acceptance

A 2019 poll conducted by IE University's Center for the Governance of Change in Spain found that 25% of citizens from selected European countries were somewhat or totally in favor of letting an artificial intelligence make important decisions about how their country is run. The following table lists the results by country:

Country Percentage
France 25%
Germany 31%
Ireland 29%
Italy 28%
Netherlands 43%
Portugal 19%
Spain 26%
UK 31%

Researchers found some evidence that when citizens perceive their political leaders or security providers to be untrustworthy, disappointing, or immoral, they prefer to replace them by artificial agents, whom they consider to be more reliable. The evidence is established by survey experiments on university students of all genders.

A 2021 poll by IE University indicates that 51% of Europeans are in favor of reducing the number of national parliamentarians and reallocating these seats to an algorithm. This proposal has garnered substantial support in Spain (66%), Italy (59%), and Estonia (56%). Conversely, the citizens of Germany, the Netherlands, the United Kingdom, and Sweden largely oppose the idea. The survey results exhibit significant generational differences. Over 60% of Europeans aged 25-34 and 56% of those aged 34-44 support the measure, while a majority of respondents over the age of 55 are against it. International perspectives also vary: 75% of Chinese respondents support the proposal, whereas 60% of Americans are opposed.

The novels Daemon and Freedom™ by Daniel Suarez describe a fictional scenario of global algorithmic regulation. Matthew De Abaitua's If Then imagines an algorithm supposedly based on "fairness" recreating a premodern rural economy.

A teacher of a Latin school and two students, 1487

A teacher, also called a schoolteacher or formally an educator, is a person who helps students to acquire knowledge, competence, or virtue, via the practice of teaching.

Informally the role of teacher may be taken on by anyone (e.g. when showing a colleague how to perform a specific task). In some countries, teaching young people of school age may be carried out in an informal setting, such as within the family (homeschooling), rather than in a formal setting such as a school or college. Some other professions may involve a significant amount of teaching (e.g. youth worker, pastor).

In most countries, formal teaching of students is usually carried out by paid professional teachers. This article focuses on those who are employed, as their main role, to teach others in a formal education context, such as at a school or other place of initial formal education or training.

Duties and functions

A teacher's role may vary among cultures.

Teachers may provide instruction in literacy and numeracy, craftsmanship or vocational training, the arts, religion, civics, community roles, or life skills.

Formal teaching tasks include preparing lessons according to agreed curricula, giving lessons, and assessing pupil progress.

A teacher's professional duties may extend beyond formal teaching. Outside of the classroom teachers may accompany students on field trips, supervise study halls, help with the organization of school functions, and serve as supervisors for extracurricular activities. They also have the legal duty to protect students from harm, such as that which may result from bullying, sexual harassment, racism or abuse. In some education systems, teachers may be responsible for student discipline.

Competences and qualities required by teachers

Teaching is a highly complex activity. This is partially because teaching is a social practice, that takes place in a specific context (time, place, culture, socioeconomic situation etc.) and therefore is shaped by the values of that specific context. Factors that influence what is expected (or required) of teachers include history and tradition, social views about the purpose of education, accepted theories about learning, etc.

Competences

The competences required by a teacher are affected by the different ways in which the role is understood around the world. Broadly, there seem to be four models:

the teacher as manager of instruction;
the teacher as caring person;
the teacher as expert learner; and
the teacher as cultural and civic person.

The Organisation for Economic Co-operation and Development has argued that it is necessary to develop a shared definition of the skills and knowledge required by teachers, in order to guide teachers' career-long education and professional development. Some evidence-based international discussions have tried to reach such a common understanding. For example, the European Union has identified three broad areas of competences that teachers require:

Working with others
Working with knowledge, technology, and information, and
Working in and with society.

Scholarly consensus is emerging that what is required of teachers can be grouped under three headings:

knowledge (such as: the subject matter itself and knowledge about how to teach it, curricular knowledge, knowledge about the educational sciences, psychology, assessment etc.)
craft skills (such as lesson planning, using teaching technologies, managing students and groups, monitoring and assessing learning etc.) and
dispositions (such as essential values and attitudes, beliefs and commitment).

Qualities

Enthusiasm

A teacher interacts with older students at a school in New Zealand.

It has been found that teachers who showed enthusiasm towards the course materials and students can create a positive learning experience. These teachers do not teach by rote but attempt to invigorate their teaching of the course materials every day. Teachers who cover the same curriculum repeatedly may find it challenging to maintain their enthusiasm, lest their boredom with the content bore their students in turn. Enthusiastic teachers are rated higher by their students than teachers who did not show much enthusiasm for the course materials.

A primary school teacher on a picnic with her students, Colombia, 2014

Teachers that exhibit enthusiasm are more likely to have engaged, interested and energetic students who are curious about learning the subject matter. Recent research has found a correlation between teacher enthusiasm and students' intrinsic motivation to learn and vitality in the classroom. Controlled, experimental studies exploring intrinsic motivation of college students has shown that nonverbal expressions of enthusiasm, such as demonstrative gesturing, dramatic movements which are varied, and emotional facial expressions, result in college students reporting higher levels of intrinsic motivation to learn. But even while a teacher's enthusiasm has been shown to improve motivation and increase task engagement, it does not necessarily improve learning outcomes or memory for the material.

There are various mechanisms by which teacher enthusiasm may facilitate higher levels of intrinsic motivation. Teacher enthusiasm may contribute to a classroom atmosphere of energy and enthusiasm which feeds student interest and excitement in learning the subject matter. Enthusiastic teachers may also lead to students becoming more self-determined in their own learning process. The concept of mere exposure indicates that the teacher's enthusiasm may contribute to the student's expectations about intrinsic motivation in the context of learning. Also, enthusiasm may act as a "motivational embellishment", increasing a student's interest by the variety, novelty, and surprise of the enthusiastic teacher's presentation of the material. Finally, the concept of emotional contagion may also apply: students may become more intrinsically motivated by catching onto the enthusiasm and energy of the teacher.

Interaction with learners

Research shows that student motivation and attitudes towards school are closely linked to student-teacher relationships. Enthusiastic teachers are particularly good at creating beneficial relations with their students. Their ability to create effective learning environments that foster student achievement depends on the kind of relationship they build with their students. Useful teacher-to-student interactions are crucial in linking academic success with personal achievement. Here, personal success is a student's internal goal of improving themselves, whereas academic success includes the goals they receive from their superior. A teacher must guide their student in aligning their personal goals with their academic goals. Students who receive this positive influence show stronger self-confidence and greater personal and academic success than those without these teacher interactions.

Students are likely to build stronger relations with teachers who are friendly and supportive and will show more interest in courses taught by these teachers. Teachers that spend more time interacting and working directly with students are perceived as supportive and effective teachers. Effective teachers have been shown to invite student participation and decision making, allow humor into their classroom, and demonstrate a willingness to play.

Teaching qualifications

In many countries, a person who wishes to become a teacher must first obtain specified professional qualifications or credentials from a university or college. These professional qualifications may include the study of pedagogy, the science of teaching. Teachers, like other professionals, may have to, or choose to, continue their education after they qualify, a process known as continuing professional development.

The issue of teacher qualifications is linked to the status of the profession. In some societies, teachers enjoy a status on a par with physicians, lawyers, engineers, and accountants, in others, the status of the profession is low. In the twentieth century, many intelligent women were unable to get jobs in corporations or governments so many chose teaching as a default profession. As women become more welcomed into corporations and governments today, it may be more difficult to attract qualified teachers in the future.

Teachers are often required to undergo a course of initial education at a College of Education to ensure that they possess the necessary knowledge, competences and adhere to relevant codes of ethics.

There are a variety of bodies designed to instill, preserve and update the knowledge and professional standing of teachers. Around the world many teachers' colleges exist; they may be controlled by government or by the teaching profession itself.

They are generally established to serve and protect the public interest through certifying, governing, quality controlling, and enforcing standards of practice for the teaching profession.

Professional standards

The functions of the teachers' colleges may include setting out clear standards of practice, providing for the ongoing education of teachers, investigating complaints involving members, conducting hearings into allegations of professional misconduct and taking appropriate disciplinary action and accrediting teacher education programs. In many situations teachers in publicly funded schools must be members in good standing with the college, and private schools may also require their teachers to be college members. In other areas these roles may belong to the State Board of Education, the Superintendent of Public Instruction, the State Education Agency or other governmental bodies. In still other areas Teaching Unions may be responsible for some or all of these duties.

Professional misconduct

Misconduct by teachers, especially sexual misconduct, has been getting increased scrutiny from the media and the courts. A study by the American Association of University Women reported that 9.6% of students in the United States claim to have received unwanted sexual attention from an adult associated with education; be they a volunteer, bus driver, teacher, administrator or other adult; sometime during their educational career.

A study in England showed a 0.3% prevalence of sexual abuse by any professional, a group that included priests, religious leaders, and case workers as well as teachers. It is important to note, however, that this British study is the only one of its kind and consisted of "a random ... probability sample of 2,869 young people between the ages of 18 and 24 in a computer-assisted study" and that the questions referred to "sexual abuse with a professional," not necessarily a teacher. It is therefore logical to conclude that information on the percentage of abuses by teachers in the United Kingdom is not explicitly available and therefore not necessarily reliable. The AAUW study, however, posed questions about fourteen types of sexual harassment and various degrees of frequency and included only abuses by teachers. "The sample was drawn from a list of 80,000 schools to create a stratified two-stage sample design of 2,065 8th to 11th grade students". Its reliability was gauged at 95% with a 4% margin of error.

In the United States especially, several high-profile cases such as Debra LaFave, Pamela Rogers Turner, and Mary Kay Letourneau have caused increased scrutiny on teacher misconduct.

Chris Keates, the general secretary of National Association of Schoolmasters Union of Women Teachers, said that teachers who have sex with pupils over the age of consent should not be placed on the sex offenders register and that prosecution for statutory rape "is a real anomaly in the law that we are concerned about." This has led to outrage from child protection and parental rights groups. Fears of being labelled a pedophile or hebephile has led to several men who enjoy teaching avoiding the profession. This has in some jurisdictions reportedly led to a shortage of male teachers.

Pedagogy and teaching

Teachers facilitate student learning, often in a school or academy or perhaps in another environment such as outdoors.

The objective is typically accomplished through either an informal or formal approach to learning, including a course of study and lesson plan that teaches skills, knowledge or thinking skills. Different ways to teach are often referred to as pedagogy. When deciding what teaching method to use teachers consider students' background knowledge, environment, and their learning goals as well as standardized curricula as determined by the relevant authority. Many times, teachers assist in learning outside of the classroom by accompanying students on field trips. The increasing use of technology, specifically the rise of the internet over the past decade, has begun to shape the way teachers approach their roles in the classroom.

The objective is typically a course of study, lesson plan, or a practical skill. A teacher may follow standardized curricula as determined by the relevant authority. The teacher may interact with students of different ages, from infants to adults, students with different abilities and students with learning disabilities.

Teaching using pedagogy also involve assessing the educational levels of the students on particular skills. Understanding the pedagogy of the students in a classroom involves using differentiated instruction as well as supervision to meet the needs of all students in the classroom. Pedagogy can be thought of in two manners. First, teaching itself can be taught in many different ways, hence, using a pedagogy of teaching styles. Second, the pedagogy of the learners comes into play when a teacher assesses the pedagogic diversity of their students and differentiates for the individual students accordingly. For example, an experienced teacher and parent described the place of a teacher in learning as follows: "The real bulk of learning takes place in self-study and problem solving with a lot of feedback around that loop. The function of the teacher is to pressure the lazy, inspire the bored, deflate the cocky, encourage the timid, detect and correct individual flaws, and broaden the viewpoint of all. This function looks like that of a coach using the whole gamut of psychology to get each new class of rookies off the bench and into the game."

Perhaps the most significant difference between primary school and secondary school teaching is the relationship between teachers and children. In primary schools each class has a teacher who stays with them for most of the week and will teach them the whole curriculum. In secondary schools they will be taught by different subject specialists each session during the week and may have ten or more different teachers. The relationship between children and their teachers tends to be closer in the primary school where they act as form tutor, specialist teacher and surrogate parent during the course of the day.

This is true throughout most of the United States as well. However, alternative approaches for primary education do exist. One of these, sometimes referred to as a "platoon" system, involves placing a group of students together in one class that moves from one specialist to another for every subject. The advantage here is that students learn from teachers who specialize in one subject and who tend to be more knowledgeable in that one area than a teacher who teaches many subjects. Students still derive a strong sense of security by staying with the same group of peers for all classes.

Co-teaching has also become a new trend amongst educational institutions. Co-teaching is defined as two or more teachers working harmoniously to fulfill the needs of every student in the classroom. Co-teaching focuses the student on learning by providing a social networking support that allows them to reach their full cognitive potential. Co-teachers work in sync with one another to create a climate of learning.

Classroom management

Teachers and school discipline

Throughout the history of education the most common form of school discipline was corporal punishment. While a child was in school, a teacher was expected to act as a substitute parent, with all the normal forms of parental discipline open to them.

In past times, corporal punishment (spanking or paddling or caning or strapping or birching the student in order to cause physical pain) was one of the most common forms of school discipline throughout much of the world. Most Western countries, and some others, have now banned it, but it remains lawful in the United States following a US Supreme Court decision in 1977 which held that paddling did not violate the US Constitution.

30 US states have banned corporal punishment, the others (mostly in the South) have not. It is still used to a significant (though declining) degree in some public schools in Alabama, Arkansas, Georgia, Louisiana, Mississippi, Oklahoma, Tennessee and Texas. Private schools in these and most other states may also use it. Corporal punishment in American schools is administered to the seat of the student's trousers or skirt with a specially made wooden paddle. This often used to take place in the classroom or hallway, but nowadays the punishment is usually given privately in the principal's office.

Official corporal punishment, often by caning, remains commonplace in schools in some Asian, African and Caribbean countries.

Currently detention is one of the most common punishments in schools in the United States, the UK, Ireland, Singapore and other countries. It requires the pupil to remain in school at a given time in the school day (such as lunch, recess or after school); or even to attend school on a non-school day, e.g. "Saturday detention" held at some schools. During detention, students normally have to sit in a classroom and do work, write lines or a punishment essay, or sit quietly.

A modern example of school discipline in North America and Western Europe relies upon the idea of an assertive teacher who is prepared to impose their will upon a class. Positive reinforcement is balanced with immediate and fair punishment for misbehavior and firm, clear boundaries define what is appropriate and inappropriate behavior. Teachers are expected to respect their students; sarcasm and attempts to humiliate pupils are seen as falling outside of what constitutes reasonable discipline.

Whilst this is the consensus viewpoint amongst the majority of academics, some teachers and parents advocate a more assertive and confrontational style of discipline (refer to Canter Model of Discipline). Such individuals claim that many problems with modern schooling stem from the weakness in school discipline and if teachers exercised firm control over the classroom they would be able to teach more efficiently. This viewpoint is supported by the educational attainment of countries—in East Asia for instance—that combine strict discipline with high standards of education.

It's not clear, however that this stereotypical view reflects the reality of East Asian classrooms or that the educational goals in these countries are commensurable with those in Western countries. In Japan, for example, although average attainment on standardized tests may exceed those in Western countries, classroom discipline and behavior is highly problematic. Although, officially, schools have extremely rigid codes of behavior, in practice many teachers find the students unmanageable and do not enforce discipline at all.

Where school class sizes are typically 40 to 50 students, maintaining order in the classroom can divert the teacher from instruction, leaving little opportunity for concentration and focus on what is being taught. In response, teachers may concentrate their attention on motivated students, ignoring attention-seeking and disruptive students. The result of this is that motivated students, facing demanding university entrance examinations, receive disproportionate resources. Given the emphasis on attainment of university places, administrators and governors may regard this policy as appropriate.

Obligation to honor students rights

Sudbury-model democratic schools claim that popularly based authority can maintain order more effectively than dictatorial authority for governments and schools alike. They also claim that in these schools the preservation of public order is easier and more efficient than anywhere else. Primarily because rules and regulations are made by the community as a whole, thence the school atmosphere is one of persuasion and negotiation, rather than confrontation since there is no one to confront. Sudbury model democratic schools' proponents argue that a school that has good, clear laws, fairly and democratically passed by the entire school community, and a good judicial system for enforcing these laws, is a school in which community discipline prevails, and in which an increasingly sophisticated concept of law and order develops, against other schools today, where rules are arbitrary, authority is absolute, punishment is capricious, and due process of law is unknown.

Occupational hazards

Teachers face several occupational hazards in their line of work, including occupational stress, which can negatively impact teachers' mental and physical health, productivity, and students' performance. Stress can be caused by organizational change, relationships with students, fellow teachers, and administrative personnel, working environment, expectations to substitute, long hours with a heavy workload, and inspections. Teachers are also at high risk for occupational burnout.

A 2000 study found that 42% of UK teachers experienced occupational stress, twice the figure for the average profession. A 2012 study found that teachers experienced double the rate of anxiety, depression, and stress than average workers.

There are several ways to mitigate the occupational hazards of teaching. Organizational interventions, like changing teachers' schedules, providing support networks and mentoring, changing the work environment, and offering promotions and bonuses, may be effective in helping to reduce occupational stress among teachers. Individual-level interventions, including stress-management training and counseling, are also used to relieve occupational stress among teachers.

Apart from this, teachers are often not given sufficient opportunities for professional growth or promotions. This leads to some stagnancy, as there is not sufficient interests to enter the profession. An organisation in India called Centre for Teacher Accreditation (CENTA) is working to reduce this hazard, by trying to open opportunities for teachers in India.

Teaching around the world

There are many similarities and differences among teachers around the world. In almost all countries teachers are educated in a university or college. Governments may require certification by a recognized body before they can teach in a school. In many countries, elementary school education certificate is earned after completion of high school. The high school student follows an education specialty track, obtain the prerequisite "student-teaching" time, and receive a special diploma to begin teaching after graduation. In addition to certification, many educational institutions especially within the US, require that prospective teachers pass a background check and psychiatric evaluation to be able to teach in classroom. This is not always the case with adult further learning institutions but is fast becoming the norm in many countries as security concerns grow.

International schools generally follow an English-speaking, Western curriculum and are aimed at expatriate communities.

Australia

Education in Australia is primarily the responsibility of the individual states and territories. Generally, education in Australia follows the three-tier model which includes primary education (primary schools), followed by secondary education (secondary schools/high schools) and tertiary education (universities or TAFE colleges).

Canada

Teaching in Canada requires a post-secondary degree Bachelor's Degree. In most provinces a second Bachelor's Degree such as a Bachelor of Education is required to become a qualified teacher. Salary ranges from $40,000/year to $90,000/yr. Teachers have the option to teach for a public school which is funded by the provincial government or teaching in a private school which is funded by the private sector, businesses and sponsors.

France

In France, teachers, or professors, are mainly civil servants, recruited by competitive examination.

Germany

In Germany, teachers are mainly civil servants recruited in special university classes, called Lehramtstudien (Teaching Education Studies). There are many differences between the teachers for elementary schools (Grundschule), lower secondary schools (Hauptschule), middle level secondary schools (Realschule) and higher level secondary schools (Gymnasium). Salaries for teachers depend on the civil servants' salary index scale (Bundesbesoldungsordnung).

India

In ancient India, the most common form of education was gurukula based on the guru-shishya tradition (teacher-disciple tradition) which involved the disciple and guru living in the same (or a nearby) residence. These gurukulam was supported by public donations and the guru would not accept any fees from the shishya. This organized system stayed the most prominent form of education in the Indian subcontinent until the British invasion. Through strong efforts in 1886 and 1948, the gurukula system was revived in India.

The role and success of a teacher in the modern Indian education system is clearly defined. CENTA Standards define the competencies that a good teacher should possess. Schools look for competent teachers across grades. Teachers are appointed directly by schools in private sector, and through eligibility tests in government schools.

Ireland

Salaries for primary teachers in Ireland depend mainly on seniority (i.e. holding the position of principal, deputy principal or assistant principal), experience and qualifications. Extra pay is also given for teaching through the Irish language, in a Gaeltacht area or on an island. The basic pay for a starting teacher is €27,814 p.a., rising incrementally to €53,423 for a teacher with 25 years service. A principal of a large school with many years experience and several qualifications (M.A., H.Dip., etc.) could earn over €90,000.

Teachers are required to be registered with the Teaching Council; under Section 30 of the Teaching Council Act 2001, a person employed in any capacity in a recognised teaching post - who is not registered with the Teaching Council - may not be paid from Oireachtas funds.

From 2006 Garda vetting has been introduced for new entrants to the teaching profession. These procedures apply to teaching and also to non-teaching posts and those who refuse vetting "cannot be appointed or engaged by the school in any capacity including in a voluntary role". Existing staff will be vetted on a phased basis.

Philippines

To become a teacher in the Philippines, one must have a bachelor's degree in education. Other degrees are also allowed as long they are able to get 18 units of professional education subjects (10 units for arts and sciences degrees). A board exam must be taken to become a professional teacher in the Philippines. Upon passing the board exam, the Professional Regulatory Commission will issue a teaching licence.

United Kingdom

Education in the United Kingdom is a devolved matter with each of the countries of the United Kingdom having separate systems.

England

Salaries for nursery, primary and secondary school teachers ranged from £20,133 to £41,004 in September 2007, although some salaries can go much higher depending on experience and extra responsibilities. Preschool teachers may earn an average salary of £19,543 annually. Teachers in state schools must have at least a bachelor's degree, complete an approved teacher education program, and be licensed.

Many counties offer alternative licensing programs to attract people into teaching, especially for hard-to-fill positions. Excellent job opportunities are expected as retirements, especially among secondary school teachers, outweigh slowing enrollment growth; opportunities will vary by geographic area and subject taught.

Scotland

In Scotland, anyone wishing to teach must be registered with the General Teaching Council for Scotland (GTCS). Teaching in Scotland is an all graduate profession and the normal route for graduates wishing to teach is to complete a programme of Initial Teacher Education (ITE) at one of the seven Scottish Universities who offer these courses. Once successfully completed, "Provisional Registration" is given by the GTCS which is raised to "Full Registration" status after a year if there is sufficient evidence to show that the "Standard for Full Registration" has been met.

For the salary year beginning April 2008, unpromoted teachers in Scotland earned from £20,427 for a Probationer, up to £32,583 after 6 years teaching, but could then go on to earn up to £39,942 as they complete the modules to earn Chartered Teacher Status (requiring at least 6 years at up to two modules per year.) Promotion to Principal Teacher positions attracts a salary of between £34,566 and £44,616; Deputy Head, and Head teachers earn from £40,290 to £78,642. Teachers in Scotland can be registered members of trade unions with the main ones being the Educational Institute of Scotland and the Scottish Secondary Teachers' Association.

Wales

Education in Wales differs in certain respects from education elsewhere in the United Kingdom. For example, a significant number of students all over Wales are educated either wholly or largely through the medium of Welsh: in 2008/09, 22 per cent of classes in maintained primary schools used Welsh as the sole or main medium of instruction. Welsh medium education is available to all age groups through nurseries, schools, colleges and universities and in adult education; lessons in the language itself are compulsory for all pupils until the age of 16.

Teachers in Wales can be registered members of trade unions such as ATL, NUT or NASUWT and a report in 2010 suggested that the average age of teachers in Wales was falling with teachers being younger than in previous years. It was suggested that a proportion of older teachers had faced discrimination and did not have their experience valued. A growing cause of concern at that time was that attacks on teachers in Welsh schools reached an all-time high between 2005 and 2010.

United States

In the United States, each state determines the requirements for getting a license to teach in public schools. Teaching certification generally lasts three years, but teachers can receive certificates that last as long as ten years. Public school teachers are required to have a bachelor's degree and the majority must be certified by the state in which they teach. Many charter schools do not require that their teachers be certified, provided they meet the standards to be highly qualified as set by No Child Left Behind. Additionally, the requirements for substitute/temporary teachers are generally not as rigorous as those for full-time professionals. The Bureau of Labor Statistics estimates that there are 1.4 million elementary school teachers, 674,000 middle school teachers, and 1 million secondary school teachers employed in the U.S.

In the past, teachers have been paid relatively low salaries. However, average teacher salaries have improved rapidly in recent years. US teachers are generally paid on graduated scales, with income depending on experience. Teachers with more experience and higher education earn more than those with a standard bachelor's degree and certificate. Salaries vary greatly depending on state, relative cost of living, and grade taught. Salaries also vary within states where wealthy suburban school districts generally have higher salary schedules than other districts. The median salary for all primary and secondary teachers was $46,000 in 2004, with the average entry salary for a teacher with a bachelor's degree being an estimated $32,000. Median salaries for preschool teachers, however, were less than half the national median for secondary teachers, clock in at an estimated $21,000 in 2004. For high school teachers, median salaries in 2007 ranged from $35,000 in South Dakota to $71,000 in New York, with a national median of $52,000. Some contracts may include long-term disability insurance, life insurance, emergency/personal leave and investment options.

The American Federation of Teachers' teacher salary survey for the 2006–07 school year found that the average teacher salary was $51,009. In a salary survey report for K-12 teachers, elementary school teachers had the lowest median salary earning $39,259. High school teachers had the highest median salary earning $41,855. Many teachers take advantage of the opportunity to increase their income by supervising after-school programs and other extracurricular activities. In addition to monetary compensation, public school teachers may also enjoy greater benefits (like health insurance) compared to other occupations. Merit pay systems are on the rise for teachers, paying teachers extra money based on excellent classroom evaluations, high test scores and for high success at their overall school. Also, with the advent of the internet, many teachers are now selling their lesson plans to other teachers through the web in order to earn supplemental income, most notably on TeachersPayTeachers.com. The United Nations Sustainable Development Goal 4 also aims to substantially increase the supply of qualified teachers through international cooperation by 2030 in an effort to improve the quality of teaching around the world.

According to a 2024 study, the status of being a teacher in the United States (as measured by occupational prestige, interest among students, the number of individuals preparing for entry, and on-the-job satisfaction) was at its lowest levels since the 1950s.

Assistant teachers

Assistant teachers are additional teachers assisting the primary teacher, often in the same classroom. There are different types around the world, as well as a variety of formal programs defining roles and responsibilities.

One type is a Foreign Language Assistant, which in Germany is run by the Educational Exchange Service (Pädagogischer Austauschdienst).

British schools employ teaching assistants, who are not considered fully qualified teachers, and as such, are guided by teachers but may supervise and teach groups of pupils independently. In the United Kingdom, the term "assistant teacher" used to be used to refer to any qualified or unqualified teacher who was not a head or deputy head teacher.

The Japanese education system employs Assistant Language Teachers in elementary, junior high and high schools.

Learning by teaching (German short form: LdL) is a method which allows pupils and students to prepare and teach lessons or parts of lessons, with the understanding that a student's own learning is enhanced through the teaching process.
