USING VIDEO ANNOTATION SOFTWARE TO ANALYZE CLASSROOM TEACHING EVENTS
While video has long been used to capture teaching episodes, illustrate classroom case studies, and demonstrate effective teaching, recent developments in video annotation applications offer the possibility for teachers to analyze and reflect upon their own teaching. Video annotation applications enable teachers to capture, code and analyze teaching episodes in authentic classroom contexts and to share those with others collaboratively (Rich & Hannafin, 2009).
This paper describes a pilot project between the researcher and two teachers using the open source video annotation applications VCode and VData (Hagedorn, Haipern & Karahalios, 2008) to analyze teaching episodes. Using a socio-cultural approach to discourse analysis, videos of teaching episodes were coded and annotated using VCode. The two teachers were trained in the use of VCode and appropriate codes were selected by the researcher and the participants. Once participants were trained, analysis was performed on independent coding of the same series of videos using VData. Cohen's Kappa calculations were made to determine agreement among the coders.
The videos of teaching events were of a teacher discussing current or controversial events with his class. Socio-Cultural Discourse Analysis (Mercer, 2004) requires attention to the moment-by-moment unfolding of events (Green & Wallat, 1981). This unfolding and signaling of interpretations, intentions. and relationships are the means by which people construct a shared definition of learning. They construct a sort of enacted narrative which they signal to each other through verbal, nonverbal, prosodic, and other communicative means. These narratives frequently result in recognized “participant structures” that help in a co-construction of meaning (Bloome, Carter, Christian, Otto & Stuart-Faris, 2005). In this project, coders identified “participation structures” used by the teacher to help students think critically by engaging in what Gordon Wells (2007) calls “triadic dialogue”.
The results of the pilot project suggest that video annotation applications like VCode and VData are useful in supporting fine grained collaborative analysis of classroom teaching. Participants found the applications easy to use and valuable in helping them reflect upon their own teaching and that of colleagues.
