This research in progress is part of a study being submitted for dissertation. The purpose of this study is to determine what types of students will be impacted by Classroom Response Systems (CRS) technology. Additionally, this research explores the nature of the outcomes experienced by students and their perceptions of leading pedagogy and practices for CRS technology in the classroom. An extensive review of the literature on CRS is included. A theoretical model based on Task- Technology Fit and Kirkpatrick's four-level model of educational outcomes is proposed as a framework to organize the existing CRS technology research and study the impact of CRS technologies.
