Using cases as triggers for teachers’ thinking about practice: A comparison of responses to animations and videos

By Patricio Herbst and Karl W. Kosko

Abstract

The AERA proposal is preserved here as summary. The full paper presented in AERA 2012 (Vancouver) is in the Main Article.This study compared conversations among groups of teachers of high school geometry that had been triggered by either a video or an animation representation of instruction and managed with an open-ended agenda. All triggers represented scenarios that departed from what was hypothesized as normative. We used as dependent variable the proportion of modal statements about instructional practice made by a group, which we argue is a good quantitative indicator of the presence of tacit group knowledge about the norms of practice. Animations and videos produced similar proportion of modal statements, but that the types of modal statements differed—with animations being associated with more statements of probability and obligation and videos being associated with more statements of inclination
