Empirical research on teachers' professional knowledge is mostly conducted worldwide with reference to the construct 'pedagogical content knowledge' (PCK) introduced by Lee S. Shulman. In the 'Consensus Model' (CM) and the 'Refined Consensus Model' (RCM), PCK was further developed and differentiated. Nevertheless, neither PCK nor CM and RCM…

Recent research and reform efforts in science education have consistently stressed the importance of coherent science instruction, in which learning opportunities are connected and contextualized by meaningful phenomena, focus on a small set of core ideas over time, and generate a need-to-know about new ideas through a set of connected lessons.…

This study investigates the relationships between professional knowledge, self-concept, and interest of pre-service physics teachers. In order to support student learning and interest development alike, teachers need a profound professional knowledge and respective motivational orientations. Developing both professional knowledge and motivational…

Using three-dimensional physical models elaborately in their learning, students can develop high-level understanding of models and modeling in science, thereby attaining higher achievement. However, there are in the literature few indications of how teachers should use three-dimensional physical models in instruction and whether teachers'…

Many educational technology proponents support the Technological Pedagogical Content Knowledge (TPACK) model as a way to conceptualize teaching with technology, but recent TPACK research shows a need for empirical studies regarding the development of this knowledge. This proof-of-concept study applies mixed-methods to investigate the…

Elements of statistical modeling can be implemented already in primary school. A prerequisite for this approach is that teachers are well-educated in this domain. Content knowledge, pedagogical content knowledge and (pedagogical) content related technological knowledge are core components of teacher education. We designed a course for elementary…

To address the special challenges of teaching computer science, adequate development of teachers' competencies during their education is extremely important. In particular, pedagogical content knowledge and teachers' beliefs and motivational orientations play an important role in effective teaching. This research field has been sparsely…

Teachers need knowledge and skills to make effective use of the growing variety of media and technology texts and tools available for use in elementary and secondary education. For this reason, pedagogical media competencies are highly relevant for teachers' professional development. The theory of media pedagogical competencies is first defined…

The integration of decision-making competence or comparable constructs into science education has been strongly enforced during the last twenty years. Germany captured the tendency with the introduction of national standards for science education that included a domain that refers to decision-making competence. This domain--"evaluation and…

Web-based digital video tools enable learners to access video sources in constructive ways. To leverage these affordances teachers need to integrate their knowledge of a technology with their professional knowledge about teaching. We suggest that this is a cognitive process, which is strongly connected to a teacher's mental model of the tool's…

Based on a major international teacher education research project--the Mathematics Teaching in the 21st Century Study (MT21)--this book investigates the pre-service preparation of middle school mathematics teachers in the United States, South Korea, Taiwan, Germany, Bulgaria, and Mexico. The study was funded by the National Science Foundation and…

In this article, a new research model for the study of pedagogical content knowledge (PCK) is presented which aims to improve teacher education. This model called "educational reconstruction for teacher education" (ERTE) represents the framework for an integrative approach to the study of science teachers' topic specific PCK, which is a…
