Talking Physics in Labwork Contexts - A Category Based Analysis of Videotapes

This study has two aims: to give some overview of methods used previously by other researchers for analysing labwork in science education and to describe a new method for analysing labwork using a category-based analysis of videotapes from labwork (CBAV). In this CBAV method, two types of categories are defined: categories for labwork contexts and categories for verbalised knowledge during work in these contexts. The method was used in five studies of labwork in France and Germany in upper secondary school and university physics classes (see contributions of Buty, Theysen et al., Hucke et al., and Sander et al., all in this volume; Haller 1999). Specific results can be found there. The method among others can help to answer questions about the link between theory and practice in different labwork contexts. It can be used complementary to other methods and permits to analyse a lot of video data in a relatively short time.
