ab: Summary: In this study the effectiveness of an arrow diagram which can help
students apply the Chain Rule was investigated. Different variations of
this diagram were used as mnemonic devices for applying the Chain Rule.
For the investigation two instruments were developed, diagnostic test
and post-test. The diagnostic test was developed to determine the
students’ difficulties with the Chain Rule and to create matched
groups. It was administered to 76 students taking the Advanced Calculus
Course. By matching according to the results of the diagnostic test,
the sample of 24 pairs of subjects is obtained. The results of the
post-test, administered after the teaching program, indicated that the
arrow diagram had positive effects on applying the Chain Rule.
