STUDENTS INTERACTION WITH COMPUTER REPRESENTATIONS - ANALYSIS OF DISCOURSE IN LABORATORY GROUPS

Language use in student laboratory groups makes apparent students' con ceptions in science, their interpretation of the activity or task, and the negotiation of the roles of the members. This article reports on a methodological approach to analyze student discourse systematically. Four Grade 12 lab groups working on microcomputer-based laboratories (MEL) are the focus of the study. The MBL experiences were used to hel p students link oscillatory motion to graphical representations. Study of student discourse reveals the role the computer plays in the group context and the ways that this context is shaped by the computer. Dev eloping a better understanding of the role of the computer in student conversations suggests ways to fruitfully construct contexts for learn ing physics.
