Freezing time: what mathematics and science teachers "see" while teaching

Our methodology was designed to tap directly into teachers' in-the-moment noticing in a way that has not been possible before. Specifically, the idea is that the clips themselves have the potential to reveal the kinds of events that teachers pay attention to during instruction. In addition, the hope is that teachers' comments in the interviews will provide valuable information concerning the ways in which noticing acts during instruction, for example, the extent to which noticing is a conscious process and the reasons behind teachers' attention to various kinds of events. The goal of this presentation is to summarize and illustrate the data we have collected thus far, and then discuss the ways in which the methodology achieved its potential as well as problems we faced in the process.
