Design and implementation of record and playback features in Classroom Learning Partner

Abstract

In this study two new recording and playback features were added to the tablet-PC-based classroom interaction system called Classroom Learning Partner. A student interaction history provides visual playback of students problem solving methods, and an audio feature provides recording and playback of student oral explanations of their problem solving. Both of these features give teachers information about students learning processes that is not available with traditional paper and pencil assessments, or even with other technology available today. In addition, the features can provide students with alternate means of expression besides writing. The system was tested in a fourth grade classroom during math lessons, with students wirelessly sending their work to the teacher. Modifications were made to the system to accommodate network restrictions on the size of the messages transmitted wirelessly. User interface design decisions were made through an iterative process. The effectiveness of the new recording and playback features was evaluated by means of classroom observations and interviews with the fourth grade students and their teacher.
