This study investigated how a group of Sri Lankan pre-service teachers changed their understanding of effective teaching during the twenty days student teaching (student teaching) period of their teacher preparation program. In order to explore changes in their understanding across this period, two methods were combined: concept maps and structured interviews. The study involved twelve student teachers preparing for teaching in secondary mathematics and science as participants. The student teachers were asked to draw concept maps of effective teaching three times: prior to beginning their student teaching period, in the middle of student teaching, and at end of the student teaching period. Half of the participants received their previous maps before developed their second and third concept maps; the other half drew their maps without reference to previous maps. Shortly after they drew their concept maps, participants were interviewed at these three stages. These interviews were audio recorded. Data were triangulated from concepts maps and interviews. Based on these data, multiple case studies were developed. Using qualitative analysis, these case studies were used to identify the changes in the student teachers� understanding about teaching and the factors that influenced these alternations. The results of the case studies were used to interpret patterns of change in participants� understanding about effective teaching. The prominent change across the maps was that over the time the participants� views of effective teaching had broadened significantly. The simple constructions of their first and second maps had become much more complex, with more concepts, more levels and more cross links. In their interviews, the student teachers provided some possible explanations for the changes, including the nature of their school experience, the support provided by workshops at their college and own their own reflections. On the basis of the these findings the study makes several recommendations for developing Sri Lankan teacher preparation and some directions for further research.
