Teaching High School Mathematics; First Course; Isomorphism: Developing the Concept Part 2
In this film, mathematician Max Beberman continues to teach 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 discover that the numbers of arithmetic may be inadequate for situations that require knowing both magnitude and direction. Beberman addresses these questions: How can a teacher emphasize that the operation used with the first set may be different from the one used with the second set? In what respect do the nonnegative reals act more like the numbers of arithmetic than do the nonpositive reals?
This is part two of a two-part lesson. Black and white picture with sound. Eastman Kodak edge code reads "triangle square," which correlates to 1964.
