Bilim Sanat Merkezi Matematik Öğretmenlerinin Kurdukları Geometrik İnşa Problemlerine Bilişsel Seviye Düzeyleri Açısından Ders İmecesi Çalışmalarının Etkisi

Turkish

This research aims to explore the effect of the lesson study practices conducted by mathematics teachers who teach gifted students to develop geometrical construction problems in terms of the Trends in International Mathematics and Science Study (TIMSS) of cognitive levels.Having used a case study method, the research was carried out with 3 mathematics teachers teaching the gifted students.With two-lesson study cycle, this research employed observation notes, interviews and students' notes as data collection tools.The data were analyzed through qualitative data analysis methods.Research results have revealed that Science Art Center mathematics teachers pose problems at the levels of recognition and applying before conducting lesson study practices.Only one teacher could address questions to the students at the level of elaborating.However, all teachers have begun to pose problems at the level of elaborating thanks to lesson study practices.This was made possible by the fact that teachers could see the effective aspects of lesson study practices and the existence of different problem types in terms of cognitive levels.Thus, similar professional development approaches should be used for the development of Science Art Center mathematics teachers.
