This document discusses using an interactive student response system called iRespond Lite in a 9th grade math class. iRespond Lite allows teachers to poll students and receive immediate feedback using clickers. When used along with an interactive whiteboard, iRespond Lite can be used for formative and summative assessments. The teacher found that using this technology increased student engagement and participation, improved test scores, and decreased behavior problems. Students also enjoyed being able to anonymously answer questions. While the batteries have a short life and replacements are expensive, the teacher feedback on iRespond Lite was overall very positive.
