Integrating the Study of Trigonometry, Vectors, and Force Through Modeling.

Peer reviewed

Doerr, Helen M. – School Science and Mathematics, 1996

Investigates the construction of understanding of the motion of an object down an inclined plane which takes place through the process of model building in an integrated algebra, trigonometry, and physics class. Discusses four major themes related to student learning through modeling that emerged from the results. Discusses implications for…
