Özet:

The aim of this study was to examine the developments in prospective middle school mathematics teachers’ subject matter knowledge and pedagogical content knowledge about quadrilaterals as they attended to a teaching experiment that was designed in a video case-based learning environment. Data was collected from eight prospective teachers during the fall semester of 2014-2015 in the scope of an elective course. In data collection process, multiple data sources were utilized such as clinical individual pre- and post-interviews, initial and revised lesson plans, teaching experiment sessions, reflection papers, group discussions and field notes. Data was analyzed by using qualitative methods. Clinical pre-interviews and initial lesson plans indicated that prospective teachers had various difficulties and inadequacies in definitions, constructions, classifications, and properties of quadrilaterals. However, in the progress of teaching experiment sessions requiring analyzing and discussing student’s mathematical thinking in micro-case videos, considerable improvements were observed mostly in prospective teachers’ pedagogical content knowledge about quadrilaterals. Thus, they developed awareness about what students’ possible conceptions, misconceptions, difficulties and their possible reasons can be. Furthermore, they enriched their instructional strategies to overcome problematic situations in students’ mathematical thinking regarding quadrilaterals. On the other hand, post-interviews revealed that there were also great developments in subject matter knowledge about quadrilaterals in addition to pedagogical content knowledge about quadrilaterals. In this sense, they corrected their errors in pre-interviews and they expanded their knowledge about definitions, constructions, classifications, and properties of quadrilaterals.
