摘要

As there has recently been an onslaught of video cases being developed and implemented with preservice teachers, it is important to evaluate how we should use these cases. This research investigates the features elementary preservice teachers consider valuable when using video cases in mathematics education. The researchers used hierarchical cluster analysis to create a dendrogram that displayed statistically significant features. The study revealed two primary clusters-(a) cross-subject lessons emphasizing adaptations and techniques to reach a variety of learners and (b) problem-based lessons with students in groups supported by lesson analysis-as well as (c) a small third cluster of collection and distribution of materials. Ultimately, such findings can be used to guide the design and incorporation of tools for using mathematics-based video cases. (Keywords: video cases, tool-based instruction, preservice teachers, technology use)
