Jean PiagetJean Piaget (August 9, 1896 – September 16, 1980) was a Swiss developmental psychologist, famous for working out a sequence of stages of cognitive development, and notable for his idea that children (and indeed adults) are continually generating theories about the external world (which are kept or dismissed depending on whether we see them working or not in practice). Biography: early lifeHe was born in Neuchâtel in the French-speaking part of Switzerland. His father, Arthur, was a professor of medieval literature at the University of Neuchâtel. He was a precocious child and developed an interest in biology, particularly of mollusks, to the point of publishing a number of papers before he graduated from high school. His long scientific career began in 1907 at the age of eleven with the publication of a short paper on the albino sparrow. Over the next seven decades he wrote more than sixty books and several hundred articles. He received a Ph.D. in natural science from the University of Neuchâtel and studied briefly at the University of Zürich. During this time, he published two philosophical papers which showed the direction of his thinking at the time, but which he later dismissed as adolescent work. His interest in psychoanalysis can also be dated to this period. He then moved from Switzerland to France, where he taught at the school for boys run by Alfred Binet, the developer of the Binet intelligence test, in Grange-aux-Belles. In 1921, he returned to Switzerland as director of the Rousseau Institute in Geneva. In 1923, he married Valentine Châtenay, and they had three children, whom he studied from infancy. The stages of cognitive developmentPiaget became a professor of psychology at the University of Geneva from 1929 to 1975 and is best known for organizing cognitive development into a series of stages-- the levels of development corresponding to infancy, childhood, and adolescence. These four stages are labeled the Sensorimotor stage, which occurs from birth to age two, (children experience through their senses), the Preoperational stage, which occurs from ages two to seven (motor skills are acquired), the Concrete operational stage, which occurs from ages seven to eleven (children think logically about concrete events), and the Formal Operational stage, which occurs after age eleven (abstract reasoning is developed here). Advancement through these levels was explained through biology and culture along with a "third factor" called equilibration, working inter-dependently with the other two. Piaget's view of the child's mindPiaget viewed children as little philosophers and scientists building their own individual theories of knowledge. Some people have used his ideas to focus on what children cannot do. Piaget however used their problem areas to help understand their cognitive growth and development. For example children may not be able to conserve five checkers spread out and report that there are more checkers. If you reduce the number to three they could conserve numbers. By focusing on the fact they cannot conserve numbers for five items you would be slow to pick up that they can do it for lower numbers. Another surprise is if you tell them a magic bunny moved the objects they would conserve higher numbers. Most people miss that children are theoretical. But many children have imaginary playmates and love to play the game of let's pretend. InfluencePiaget's theory of cognitive development has proved influential, notably on the work of Lev Vygotsky and of Lawrence Kohlberg. Among others, the philosopher and social theorist Jürgen Habermas has incorporated it into his work, most notably in The Theory of Communicative Action. Piaget also had a considerable impact in the field of computer science and artificial intelligence. Seymour Papert used Piaget's work while developing the Logo programming language. Alan Kay used Piaget's theories as the basis for the Dynabook programming system concept, which was first discussed within the confines of the Xerox Palo Alto Research Center, or Xerox PARC. These discussions led to the development of the Alto prototype, which explored for the first time all the elements of the graphical user interface (GUI), and influenced the creation of user interfaces in the 1980's and beyond. The philosopher Thomas Kuhn credited Piaget's work in helping him understanding the transition between modes of thought which characterised his theory of paradigm shifts. Piaget has had a substantial impact on approaches to education. In Conversations with Jean Piaget, he says: "Education, for most people, means trying to lead the child to resemble the typical adult of his society... But for me, education means making creators... You have to make inventors, innovators, not conformists." (Bringuier, 1980, p.132). Major works and achievementsSingle "best read"

He died in Danbury, Connecticut. In Conversations with Jean Piaget, he says: "Education, for most people, means trying to lead the child to resemble the typical adult of his society.. His many accomplishments included a breed of chicken that at one point accounted for the overwhelming majority of all egg-laying chickens sold across the globe. Piaget has had a substantial impact on approaches to education. During his later years he made a number of advances in the field of agricultural science. The philosopher Thomas Kuhn credited Piaget's work in helping him understanding the transition between modes of thought which characterised his theory of paradigm shifts. Wallace resumed his farming interests, and resided in South Salem, New York. These discussions led to the development of the Alto prototype, which explored for the first time all the elements of the graphical user interface (GUI), and influenced the creation of user interfaces in the 1980's and beyond. In 1952 Wallace published Why I Was Wrong, in which he explained that his seemingly-trusting stance toward the Soviet Union and Stalin stemmed from inadequate information about Stalin's excesses and that he, too, now considered himself an anti-Communist. Alan Kay used Piaget's theories as the basis for the Dynabook programming system concept, which was first discussed within the confines of the Xerox Palo Alto Research Center, or Xerox PARC. Some of his followers believed that his warnings of a possible American pre-emptive attack on the Soviet Union may have prevented such a war. Seymour Papert used Piaget's work while developing the Logo programming language. The party's opposition to Truman's hard-line stance against the Soviets brought it into disrepute especially as events in Europe aroused fears of Soviet expansionism. Piaget also had a considerable impact in the field of computer science and artificial intelligence. His acceptance of the support of American Communists also drew the ire of the Anti-Communist sentiment of the time. Among others, the philosopher and social theorist Jürgen Habermas has incorporated it into his work, most notably in The Theory of Communicative Action. His campaign was unusual for his time in that it included African American candidates campaigning alongside white candidates in the American South, and during the campaign he refused to appear before segregated audiences or eat/stay in segregated establishments. Piaget's theory of cognitive development has proved influential, notably on the work of Lev Vygotsky and of Lawrence Kohlberg. Many of his proposals were eventually enacted, such as the Civil Rights Act of 1964, the Voting Rights Act of 1965, Medicare (1965) and Medicaid (1965). But many children have imaginary playmates and love to play the game of let's pretend. His platform was far ahead of its time, advocating such positions as an end to segregation, full voting rights for blacks, and universal government health insurance. Most people miss that children are theoretical. presidential election. Another surprise is if you tell them a magic bunny moved the objects they would conserve higher numbers. He left his editorship position in 1948 to make an unsuccessful run as a Progressive Party candidate in the 1948 U.S. By focusing on the fact they cannot conserve numbers for five items you would be slow to pick up that they can do it for lower numbers. On the declaration of the Truman Doctrine in 1947, he predicted it would mark the beginning of "a century of fear". If you reduce the number to three they could conserve numbers. Following his term as Secretary of Commerce, Wallace became the editor of The New Republic magazine, using his position to criticize vociferously Truman's hawkish foreign policy. For example children may not be able to conserve five checkers spread out and report that there are more checkers. Truman, who had become president when Roosevelt's death midterm, and who regarded Wallace as too critical of Truman's foreign policy. Piaget however used their problem areas to help understand their cognitive growth and development. Wallace served in this post from March 1945 to September 1946, when he was fired by Harry S. Some people have used his ideas to focus on what children cannot do. Roosevelt placated Wallace by appointing him Secretary of Commerce. Piaget viewed children as little philosophers and scientists building their own individual theories of knowledge. Franklin D. Advancement through these levels was explained through biology and culture along with a "third factor" called equilibration, working inter-dependently with the other two. Truman as the new Vice Presidential candiate. These four stages are labeled the Sensorimotor stage, which occurs from birth to age two, (children experience through their senses), the Preoperational stage, which occurs from ages two to seven (motor skills are acquired), the Concrete operational stage, which occurs from ages seven to eleven (children think logically about concrete events), and the Formal Operational stage, which occurs after age eleven (abstract reasoning is developed here). Thus due to concerns over his far left beliefs, perceived naivete regarding Joseph Stalin, and unorthodox New Age tendencies, the Democratic Party bumped Wallace from its ticket in 1944 They replaced Wallace with Missouri Senator Harry S. Piaget became a professor of psychology at the University of Geneva from 1929 to 1975 and is best known for organizing cognitive development into a series of stages-- the levels of development corresponding to infancy, childhood, and adolescence. 1944, as FDR's health began to fail, their was a growing likelyhood that Wallace, as his running-mate in the upcomming presidential election, would succeed him. In 1923, he married Valentine Châtenay, and they had three children, whom he studied from infancy. Department of Commerce. In 1921, he returned to Switzerland as director of the Rousseau Institute in Geneva. This met opposition from the U.S. He then moved from Switzerland to France, where he taught at the school for boys run by Alfred Binet, the developer of the Binet intelligence test, in Grange-aux-Belles. These clauses required producers to pay fair wages and provide safe working conditions for their employees, and it committed the United States to paying for up to half of the required improvements. His interest in psychoanalysis can also be dated to this period. He convinced the BEW to add "labor clauses" to contracts with Latin American producers. During this time, he published two philosophical papers which showed the direction of his thinking at the time, but which he later dismissed as adolescent work. Wallace was far ahead of his time in trade relationships with Latin America. in natural science from the University of Neuchâtel and studied briefly at the University of Zürich. His trip proved a success and helped convince 12 Latin American countries to declare war on Germany. He received a Ph.D. In 1943 Wallace made a goodwill tour of Latin America, shoring up support among important allies. Over the next seven decades he wrote more than sixty books and several hundred articles. The speech, and the book of the same name which appeared the following year, proved quite popular, but it earned him enemies among the Democratic leadership, among important allied leaders like Winston Churchill, and among business leaders and conservatives. His long scientific career began in 1907 at the age of eleven with the publication of a short paper on the albino sparrow. This speech, grounded in Christian references, laid out a positive vision for the war beyond the simple defeat of the Nazis. He was a precocious child and developed an interest in biology, particularly of mollusks, to the point of publishing a number of papers before he graduated from high school.
