Abstract

Research has shown that right triangle trigonometry poses a significant learning challenge for high school geometry students. One potential source of this challenge is the tendency for students to experience right triangle trig as an exclusively action-oriented set of strategies (i.e. SOHCAHTOA). This article describes a teaching experiment where students built understanding of right triangle trig using a unique set of manipulatives and direct measurement. Results of the experiment show that the lessons provided opportunities for students to develop their understanding beyond action-oriented strategies.
