Description

The article organizes experimental work on geometry teaching around three questions: whether the desired results are obtained under a given method, what the best method of obtaining them is, and whether obtaining them transfers to other subjects. It states that "If the three lines of investigation indicated were carefully carried out and the questions involved settled, there would be no doubt as to the correct aims and proper methods in teaching the subject." The framework links aim-verification, method comparison, and transfer testing into one research program.
