Catherine Stern
Catherine Brieger Stern (1894–1973) was a German psychologist and educator. Born under the name Käthe Brieger, she developed sets of mathematical manipulatives similar to Cuisenaire rods for children to use in building up their number sense and knowledge of arithmetic. Her book, ''Children Discover Arithmetic'' (1949) was used by others to work on the problems that children face when learning arithmetic. In 1938, she emigrated to the United States. From 1940 to 1943, she was a research assistant to Max Wertheimer at the New School for Social Research.

Mathematical Manipulatives
In mathematics education, a manipulative is an object which is designed so that a learner can perceive some mathematical concept by manipulating it, hence its name. The use of manipulatives provides a way for children to learn concepts through developmentally appropriate hands-on experience. The use of manipulatives in mathematics classrooms throughout the world grew considerably in popularity throughout the second half of the 20th century. Mathematical manipulatives are frequently used in the first step of teaching mathematical concepts, that of concrete representation. The second and third steps are representational and abstract, respectively. Mathematical manipulatives can be purchased or constructed by the teacher. Examples of common manipulatives include number lines, Cuisenaire rods; fraction strips, blocks, or stacks; base ten blocks (also known as Dienes or multibase blocks); interlocking linking cubes (such as Unifix); construction sets (such as Polydron and Zo ...

Cuisenaire Rods
Cuisenaire rods are mathematics learning aids for students that provide an interactive, hands-on way to explore mathematics and learn mathematical concepts, such as the four basic arithmetical operations, working with fractions and finding divisors. In the early 1950s, Caleb Gattegno popularised this set of coloured number rods created by Georges Cuisenaire (1891–1975), a Belgan primary school teacher, who called the rods ''réglettes''. According to Gattegno, "Georges Cuisenaire showed in the early 1950s that students who had been taught traditionally, and were rated 'weak', took huge strides when they shifted to using the material. They became 'very good' at traditional arithmetic when they were allowed to manipulate the rods." History The educationalists Maria Montessori and Friedrich Fröbel had used rods to represent numbers, but it was Georges Cuisenaire who introduced the rods that were to be used across the world from the 1950s onwards. In 1952 he published ''Les nombres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arithmetic
Arithmetic () is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers— addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today. History The prehistory of arithmetic is limited to a small number of artifacts, which may indicate the conception of addition and subtraction, the best-known being the Ishango bone from central Africa, dating from somewhere between 20,000 and 18,000 BC, although its interpretation is disputed. The earliest written records indicate the Egyptians and Babylonians used all the elementary arithmetic operations: addition, subtraction, multiplication, and division, as early as 2000 BC. These artifacts do not always reveal the specific process used for solving problems, but t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max Wertheimer
Max Wertheimer (April 15, 1880 – October 12, 1943) was an Austro-Hungarian psychologist who was one of the three founders of Gestalt psychology, along with Kurt Koffka and Wolfgang Köhler. He is known for his book, ''Productive Thinking'', and for conceiving the phi phenomenon as part of his work in Gestalt psychology. Wertheimer became interested in psychology and studied under Carl Stumpf at the University of Berlin.Hothersall, D. (2003) Wertheimer then went on to obtain his PhD in 1904 under Oswald Külpe, at the University of Würzburg and then began his intellectual career teaching at the Institute for Social Research at Frankfurt University. For a short time, he left Frankfurt to work at the Berlin Psychological Institute, but returned in 1929 as a full professor. Wertheimer eventually joined the faculty of The New School in New York, a position he held until his death. Early life Max Wertheimer was born on April 15, 1880, in Prague, then part of the Bohemian Austria-Hunga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New School For Social Research
The New School for Social Research (NSSR) is a graduate-level educational institution that is one of the divisions of The New School in New York City, United States. The university was founded in 1919 as a home for progressive era thinkers. NSSR explores and promotes what they describe as global peace and global justice. It enrolls more than 1,000 students from all regions of the United States and from more than 70 countries. History The New School for Social Research was founded in 1919 by, among others, Charles Beard, John Dewey, James Harvey Robinson, and Thorstein Veblen. In 1933, what became known as the University in Exile, had become a haven for scholars who had been dismissed from teaching positions by the Italian fascists under Benito Mussolini or had to flee Adolf Hitler and the National Socialist German Workers Party. The University in Exile was initially founded by the director of the New School, Alvin Saunders Johnson, through the financial contributions of Hiram Ha ...

Random House
Random House is an American book publisher and the largest general-interest paperback publisher in the world. The company has several independently managed subsidiaries around the world. It is part of Penguin Random House, which is owned by German media conglomerate Bertelsmann. History Random House was founded in 1927 by Bennett Cerf and Donald Klopfer, two years after they acquired the Modern Library imprint from publisher Horace Liveright, which reprints classic works of literature. Cerf is quoted as saying, "We just said we were going to publish a few books on the side at random," which suggested the name Random House. In 1934 they published the first authorized edition of James Joyce's novel ''Ulysses'' in the Anglophone world. ''Ulysses'' transformed Random House into a formidable publisher over the next two decades. In 1936, it absorbed the firm of Smith and Haas—Robert Haas became the third partner until retiring and selling his share back to Cerf and Klopfer in 19 ...
