Content Knowledge For Teaching

This study aims to develop and validate a new instrument for measuring chemistry teachers’ perceptions of Pedagogical Content Knowledge for teaching Chemistry Core Competencies (PCK_CCC) in the context of new Chinese chemistry curriculum reform. The five constructs and the initial 17 items in the new instrument were contextualized by the PCK pentagon model (Park S. and Oliver J. S., (2008), J. Res. Sci. Teach., 45(7), 812–834.) with the notions of the Senior High School Chemistry Curriculum Standards (Ministry of Education, P. R. China, 2017). 210 chemistry teachers from a University-Government-School initiative voluntarily participated in this study. The findings from item analysis, confirmatory factor analysis and correlation analysis provide sufficient empirical evidence to support the convergent and discriminant validity of the instrument. The concurrent validity of the instrument was confirmed by testing mean differences among teacher demographic groups. The high Cronbach's coefficient alpha values show good internal consistency reliability of the instrument. Integrating the evidence from theory and data, we documented a valid and reliable PCK_CCC instrument with five constructs consisting of 16 items. This study provides a thorough process for developing and validating instruments that address teacher perceptions of their PCK in a particular subject domain. The valid and reliable PCK_CCC instrument would be beneficial for teacher education researchers and teacher professional programs.
