통계수업 관찰에서 나타나는 예비 중등 수학교사의 전문가적 안목(professional vision)

Abstract

This study investigated preservice secondary mathematics teachers’ professional vision as they watched a statistics lesson video clip and compared it with U.S. preservice teachers’ professional vision in a previous study conducted in the similar context(Shin, 2020). Data were collected from 7 preservice teachers who reported noteworthy teaching-learning moments in the video clip and analyzed based on their selective attention and knowledge-based reasoning. Findings showed that the preservice teachers paid attention to the teacher, students, and lesson environments evenly while observing the statistics lesson video. The extent to which the preservice teachers attended to students and students’ statistical thinking was similar to those of preservice teachers in the United States. While the U.S. preservice teachers focused mostly on the teacher’s pedagogical decisions, the preservice teachers in the current study paid also attention to technological tools, statistical contents, and classroom atmosphere. In addition, compared to the U.S. preservice teachers, the preservice teachers in the present study were more likely to describe and evaluate what they attended to and interpret students’ thinking based on general pedagogical knowledge rather than statistical knowledge for teaching. Based on the findings, the needs for preservice teacher education to develop professional vision based on statistical knowledge for teaching were discussed.
