Transformations in the Plane: Towards Interpretations and Proofs of Linearity
Page: 1469
In recent years, student reasoning in linear algebra has been a rich area of research, but relatively few studies have focused on linearity and proof in this area (Stewart et al., 2019). In this study, we analyze students’ evoked concept images of linear transformations in the context of a Desmos module focused on transformations in the plane and identify aspects of the module that students reported finding helpful for their learning. This report draws on the written responses of 54 U.S. undergraduate linear algebra students at the end of a unit on linear transformations.
