The Art of Teaching: Rectangular Coordinates and Signed Numbers in Seventh Grade Mathematics

Abstract

In discussing modern trends in mathematics, Professor Reeve of Columbia University, has often mentioned the gradual “leveling down” in this field. That is, instead of introducing various phases of the subject at an earlier stage of the teaching process, it is deferred until later. Thus we are now able to find college algebra texts that should provide no challenge to a good high-school group.
