This dissertation describes a qualitative case study that investigated novice teachers’ video-aided reflection on their own teaching. To date, most studies that have investigated novice teachers’ video-aided reflective practice have focused on examining novice teachers’ levels of reflective writing rather than the cognitive processes involved during their reflection. Few studies have probed how novice teachers schematize and theorize their newly acquired and/or existing knowledge during video-aided reflection. The purpose of this study was to explore novice teachers’ cognitive processes, particularly video-aided schematization and theorization (VAST), which is a set of cognitive processes that help novice teachers construct, restructure and reconstruct their professional knowledge and pedagogical thinking while reflecting on videos of their own teaching. The researcher measured novice teachers’ VAST by examining their schema construction and automation in terms of schema accretion, schema tuning and schema restructuring. The study attempted to answer the following questions: a) What is the focus of novice teachers’ video-aided reflection? and b) How do novice teachers connect the focus of their reflections to their prior knowledge and future actions? The findings indicate that video-aided reflection could help novice teachers (1) notice what was needed to improve in their teaching practice, (2) realize how various elements in teaching were interrelated, and (3) construct, restructure, or reconstruct their professional knowledge – in other words, develop their schemata about teaching and learning through VAST. With a more developed and mature schemata, novice teachers could be able to better understand the various elements involved in teaching and learning, and handle the situations they encounter in their teaching. This may be because people’s schemata can provide the link between concepts and patterns of what they do (Rumelhart, 1980). This research has provided a new way to look at novice teachers’ video-aided reflection: how the cognitive processes they experience during their reflection can help them develop the knowledge about teaching and learning, and how their cognitive development can help them grow toward becoming teaching experts. The research findings add to the knowledge base about the use of video technology in teachers’ self-reflection and professional development in teacher education.
