General pedagogical knowledge among pre-service vocational teachers : measurement and development during teacher education

Abstract

„The relevance of general pedagogical knowledge (GPK) for vocational teachers is internationally recognised but has not yet been systematically investigated. In this study, the GPK of pre-service vocational teachers is analysed using an established GPK test. Structural equation modelling was used to analyse the test's psychometric quality and GPK development using a cohort-sequential design (N = 374). The results indicate that the test measures GPK one-dimensionally and that there is substantial GPK development among pre-service teachers (d = .68–1.63). Our study suggests that previous studies may have been biased (e.g., because they assumed the test measures GPK multidimensionally).” (authors’ abstract; BIBB-Doku)
