Reference Angles of Trigonometric Functions

This learning module focused on using technology to help students visualize trigonometric concepts. The module was self-paced and highly interactive. Students were able to take notes on a companion guide as they learned new concepts.

Current computer technology has the capability of addressing challenges in teaching and learning trigonometry. It allows multiple representations of trigonometric concepts to be illustrated side by side, as well as efficient construction of images needed to help students understand course concepts and to develop their mental visual imagery skills. Additionally, computer technology provides opportunities for students to actively engage in constructivist learning of new concepts while receiving specific and immediate feedback. This module was developed and implemented as a part of my dissertation which focused on the impact of interactive computer-aided instruction in teaching and learning trigonometry. The study hypothesized that the use of interactive computer-aided instruction would have a positive impact on students’ mastery of trigonometry concepts as well as students’ perceptions of trigonometry.
