Student conceptions of three-dimensional solids
Page: 1393
In the 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 several tasks in which students must decode a de- scription of a solid figure and answer questions assessing the strength of their conception of the figure. Presented here are findings from the analysis interviews and group work on one of these tasks in which students are asked to build a clay model of the solid region described by a set of inequalities in three variables.
