Abstract

Given its high importance as a central competence in the natural sciences in schools, scientific inquiry is not yet adequately represented in preservice science teacher education at university level. In preservice chemistry teacher education at Technische Universität Braunschweig, scientific inquiry is taught explicitly and promoted with experimental problem solving in an organic chemistry laboratory. In addition, cognitive scaffolding is provided by explanatory videos on scientific reasoning and practical skills for students’ prelaboratory preparation. In the article, the explanatory videos are introduced as a tool for learning and evaluated regarding their influence on students’ self-concept of ability. While significant gains were found in the students’ self-concept of ability due to participation in the laboratory, there was no interaction of the exposure to the videos. The insights on explanatory videos for the undergraduate laboratory are discussed.
