A study on the development and analysis of a test of pedagogical content knowledge(PCK) of elementary school pre-service teachers in the areas of geometry and measurement

Objectives The purpose of this study was to develop and analyze items that could test elementary pre-service teachers' pedagogical content knowledge (PCK) in the areas of geometry and measurement. Methods We developed a test instrument to assess pedagogical content knowledge (PCK) in the area of geometry and measurement and conducted a test on 219 prospective elementary school teachers in Gyeongnam. Through this, we verified the validity and reliability of the test instrument. In addition, we analyzed the pedagogical content knowledge (PCK) of prospective elementary school teachers in the area of g eometry and measurement. Results The test instrument consisted of 27 items in four factors: mathematics curriculum, mathematics curriculum content, mathematics teaching and learning content, and mathematics teaching and learning methods. The reliability of the developed test instrument was .917, and each factor and item had internal consistency. The average of mathematics curriculum knowledge was 2.75, the average of mathematics teaching and learning method knowledge was 4.44, and there was a difference in didactic content knowledge between the second and fourth grades. Conclusions This study diagnoses the didactic content knowledge of elementary school pre-service teachers in the areas of geometry and measurement, and provides implications for the design and direction of pre-service teacher education programs.
