Anchored instruction is designed to present problems in a meaningful context to allow for investigations into real life environments. The Jasper Project was created to allow students to investigate mathematical dilemmas using anchored instruction techniques. This study uses case study methods to examine the perceptions that preservice teachers have toward the use of anchored instruction after having the opportunity to investigate and evaluate a Jasper predicament as a group. The guiding research questions were: 1) Through exploration and evaluation, are preservice teachers able to determine significance of using anchored instruction with their future students? And if they see significance, 2) How do preservice teachers envision student learning and mathematical growth using anchored instruction? Four individual cases were evaluated, specifically examining the features of anchored instruction each preservice teacher described. The preservice teachers were optimistic about the utilization of anchored instruction and described features that support student learning and growth.

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) problembased 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.

After interacting with a Best Practices video case whole class and individually, preservice teachers were asked to reflect on what features they deemed helpful. In addition, they were asked to reflect on what additional features they would find desirable. The constant comparative method was used to analyze the data (Glaser, 1965). Three features were considered constructive: (1) modeling of teaching techniques (2) supplemental materials to support the video case and (3) observing classroom management. Concerning additional features, they wanted (1) an analysis of the lesson (2) improvements in technology and editing and (3) extended video case selections. The expressed features can guide the creation and use of video cases in preservice teachers’ education by providing direction for integration and development.
