The purpose of this study is to examine the ways in which PSMTs' professionally notice middle school students' mathematical thinking on a technology enhanced mathematical task. Findings show that every preservice mathematics teacher included a discussion of the middle school students' interaction with the technology in their noticing prompts, demonstrating that PSMTs recognized that the middle school students' mathematical understanding was tied to their interactions with the technology. Additionally, results from PSMTs' justifications for their predictions of middle school students' responses to the task, incorporated the middle school students language and described how the middle school students would interact with the technology.
