Öğretmen Adaylarının İstatistiği Öğretme Bilgilerinin Öğretmenlik Uygulaması Temelli Ders Araştırmaları Bağlamında İncelenmesi
Özet
The aim of this study was to improve pre-service middle school mathematics
teachers’ statistical knowledge for teaching via practicum based lesson study. Also
how practicum based lesson study supports or restricts statistical knowledge for
teaching was examined. Holistic single case study design was adopted. The
participants were three pre-service teachers who enrolled in a public university in
Ankara. Pre-service teachers implemented three lesson study cycles. The data
were collected through statistical knowledge for teaching tasks, interviews,
documents, video recordings, observations, field notes and reflective papers. The
descriptive analysis was used. Key developmental understandings were defined
and changes in participants’ knowledge of content, teaching and students were
examined. Also, how participants’ knowledge has changed among and within
lesson study cycles was examined. In addition, how lesson study has supported or
restricted participants’ development was examined. Results showed that
participants improved statistical knowledge for teaching by attending practicum
based lesson study. When pre-service teachers realized that doing statistics
started with the formulation of questions, other key developmental understandings
have developed. It was observed that the changes in knowledge of content
supported the development of knowledge of teaching and students. Furthermore
changes in knowledge of teaching and of students were also found related. To
conclude, the practicum based lesson study developed pre-service teachers’
knowledge for teaching statistics. Hence, the integration of lesson study to
undergraduate programs for teacher education is recommended. The key
developmental understandings emerged in this study could contribute to the
theoretical framework for describing teacher knowledge for teaching statistics.
