When the former Soviet Union appeared to have gained a temporary advantage in a "space race" with the United States by launching Sputnik, the first artificial Earth satellite, part of the American response was to develop new curricula for science and mathematics instruction. One component of the new curriculum was the "new math," an emphasis on abstract mathematical principles in place of rote learning of mathematical facts. The "new math" was at best a partial success. Ignoring the tradition of Pestalozzi and his followers, it expected students to deal with abstract concepts without having had the opportunity to become familiar with the facts and techniques of ordinary addition and multiplication at the concrete and operational level.

In hindsight, Pestalozzi appears to have been part of an educational tradition that includes Maria Montessori , John Dewey , and Jean Piaget. The research of these educators and psychologists has focused on the mental development of children and their growth through gradual progression through stages of concrete thinking, operationalism, and later abstract thinking, with the abstract conceptual stage considered the highest or most mature stage of development.

This position is not without controversy.

Any alternative school of thought holds that individuals differ in "learning style," and that individuals not comfortable with abstract relationships may function as well or better in all important human activities than "abstract thinkers" do. This group includes teachers who consider themselves "ethnomathematicians" and feel that traditional mathematics instruction depends too heavily on the assumptions of white European culture, and that more concrete ways of thinking also provide a valid approach to mathematical truth.

A number of important associations of mathematicians and mathematics teachers are now involved in decisions affecting mathematics education in the United States. The American Mathematical Society was originally founded as the New York Mathematical Society in and, adopting its present name in , is devoted primarily to original research in mathematics.

The Mathematical Association of America was organized in for individuals primarily interested in the teaching of mathematics on the college level. Concern with the teaching of mathematics at the primary and secondary levels would rest with the National Education Association , originally organized as the National Teacher's Association in This organization appointed a number of committees over the period to make recommendations about the content of secondary school mathematics and the mathematics to be required for college admission.

In the National Council of Teachers of Mathematics was formed by the National Education Association in order to bridge the gap between the more general concerns of the National Education Association and the Mathematical Association of America.

It is likely that debate about the proper way or ways to teach mathematics will continue for some time. In recent years the relatively poor showing of American students compared to students from other nations has served to renew debate on the best ways to tech mathematics in a culturally diverse society. With the number of employment opportunities for the mathematically literate increasing rapidly, means will need to be found, either to involve more professional mathematicians in the educational process or to provide the future mathematics teacher with a better understanding of mathematics and the methods of teaching it to contemporary students.

Nineteenth-Century Efforts to Promote Mathematics Education from Grade School to the University Level Overview Economic and political factors combined to foster an increased emphasis on mathematics education over the course of the nineteenth century.

Background Ever since Plato refused some 2, years ago to admit to his academy students who were ignorant of mathematics, there has been a connection between mathematics and education. Learn more about citation styles Citation styles Encyclopedia.

The product or quotient of a debt and a fortune is a debt. The product or quotient of a fortune and a debt is a debt. The ancient Greeks did not really address the problem of negative numbers, because their mathematics was founded on geometrical ideas. Lengths, areas, and volumes resulting from geometrical constructions necessarily all had to be positive. Their proofs consisted of logical arguments based on the idea of magnitude. Magnitudes were represented by a line or an area, and not by a number like 4.

In this way they could deal with 'awkward' numbers like square roots by representing them as a line.

For example, you can draw the diagonal of a square without having to measure it see note 2 below. Negative numbers did not begin to appear in Europe until the 15th century when scholars began to study and translate the ancient texts that had been recovered from Islamic and Byzantine sources. This began a process of building on ideas that had gone before, and the major spur to the development in mathematics was the problem of solving quadratic and cubic equations. As we have seen, practical applications of mathematics often motivate new ideas and the negative number concept was kept alive as a useful device by the Franciscan friar Luca Pacioli - in his Summa published in , where he is credited with inventing double entry book-keeping.

In the 17th and 18th century, while they might not have been comfortable with their 'meaning' many mathematicians were routinely working with negative and imaginary numbers in the theory of equations and in the development of the calculus. Negative numbers and imaginaries are now built into the mathematical models of the physical world of science, engineering and the commercial world. There are many applications of negative numbers today in banking, commodity markets, electrical engineering, and anywhere we use a frame of reference as in coordinate geometry, or relativity theory.

Although the first set of rules for dealing with negative numbers was stated in the 7th century by the Indian mathematician Brahmagupta, it is surprising that in the British mathematician Francis Maseres was claiming that negative numbers " In BCE the Chinese number rod system see note1 below represented positive numbers in Red and Negative numbers in black.
