Student conceptions of three-dimensional solids
Page: 209
In the exploratory study presented in this paper, the authors aim to construct a model for the processes by which students in a multivariable calculus class conceptualize solid regions in three dimensions. We designed and recorded student work from two tasks in which students must decode a description of a solid figure and answer questions assessing the strength of their con- ception of the figure. Presented here are findings and common themes that emerged from the analysis of interviews and group work on two of these tasks, including five generalizable obser- vations about how students process three-dimensional information.
