Previous work has shown that the formation of misconceptions remains one of the most significant barriers to progress for chemistry students. Determination and visualization of the shapes of molecules using valence shell electron pair repulsion theory (VSEPR theory) is an example of an abstract concept that students often find difficult to learn. Concepts may be better understood if the learning process were supported by innovative, interactive, learning resources. In order to address the conceptual difficulties that students may encounter when using VSEPR theory, an activity has been developed that is supported by simple molecular models. Activity cards give students the opportunity to work through the steps required to predict the shape of a molecule in an engaging manner that promotes social learning. Students were tested before and after the activity. A statistically significant improvement in scores (p = 0.001) was found, which indicates that the activity cards and molecular models could help students understand the topic.
