| Abstract Title: | Sines and Signs - Student difficulties with trigonometric vector component problems |
|---|---|
| Abstract: | We investigated student understanding of simple vector component problems. Students in a calculus-based introductory physics class were given a variety of vector component questions, with the angle placed in various orientations. For example, the angle could be given with respect to vertical/horizontal, or with respect to the tip/tail of the vector. Student solution methods, as well as relative frequencies of different errors, were found to depend on the configuration of the given angle. Overall results suggest that many students based their answers on the most commonly seen canonical angle configuration, while others used their own methods to maintain the validity of the canonical solution path. Possible training methods to correct for the misconceptions involved are discussed. |
