Abstract
Abstract. Spatial thinking represents an ongoing challenge in
geoscience education, but concrete manipulatives can bridge this gap by
illustrating abstract concepts. In an undergraduate optical mineralogy lab
session, TotBlocks were used to illustrate how crystal structures influence
properties such as cleavage and pleochroism. More abstracted properties,
e.g., extinction angles, were increasingly difficult to illustrate using
this tool.
