Teaching High School Mathematics; First Course; Isomorphism: Developing the Concept Part 1
Mathematician Max Beberman instructs students from the Mathematics Institute how to teach the concept of isomorphism to their pupils.
He shows that when students are first introduced to real numbers they find that the numbers of arithmetic are sometimes inadequate for situations that require knowing both magnitude and
direction. Beberman addresses these questions: Are the nonnegative real numbers different from the numbers of arithmetic? Why can we sometimes find the answer to one problem by solving another
one instead? This is part one of a two-part lesson. Black and white picture with sound. Eastman Kodak edge code reads "triangle square," which correlates to 1964.
