Video cases have frequently been developed to model educational instances from an authentic elementary classroom setting for preservice teachers in mathematics and science. Preservice teachers' predilections regarding mathematics and science video cases should influence how cases are integrated within the university classroom. Using Personal Construct Theory, constructs were identified, used to create repertory grids, rated and then analyzed using hierarchical cluster analysis. Three primary clusters were discovered along with a minor fourth cluster. When designing or using a video case with preservice teachers, these findings can help determine the content for integration.
