Development and Changes in Student Teachers´ Knowledge Concerning Diagnostic in Chemistry Teaching - A Longitudinal Case Study

Abstract

A knowledge about pedagogical diagnosis is important for professional teachers for teaching heterogeneous chemistry classes. For chemistry teachers, the knowledge about their students` perceptions, attitudes, knowledge, previous experience or their interest is crucial for planning lessons. Therefore, the diagnosis is a key component of teachers` knowledge. However, research in this area is still underrepresented. It is clear, that the development of teachers` knowledge about diagnosis in chemistry teaching and learning should be started during the university teacher education program. But, how does this knowledge develop or change during the teacher training program in chemistry education? This paper attempts to investigate this development with a longitudinal interview case study. Two chemistry student teachers participated the study and were interviewed at seven different time points during their teacher education program. The interview and the analysis are based on the definition by Jäger with a focus on the four dimensions of the diagnostic competence: i. Competence Knowledge, ii. Conditional Knowledge, iii. Technological Knowledge and iv. Knowledge of Change. The analysis of the interviews follows documentary method. The results show a different development of student teachers, which allowed a contrasting view of the students. From this, implications for the teacher training will be presented.

Impact of an Experiment-Based Intervention on Pre-Service Primary School Teachers’ Experiment-Related and Science Teaching-Related Self-Concepts

“…There are two to four stations per session with several sets of experimental materials. In the following, a 'pedagogical biplane' (Tolsdorf & Markic, 2018;Wahl, 2013) is applied: Being in the role of learners, the preservice teachers can learn science content, learn about scientific inquiry (e.g. principles of systematic observations), and learn to do inquiry (e.g.…”

Development of a Learning Environment to Enhance Preservice Physics Teachers’ Diagnostic Competence in Terms of Students’ Conceptions

“…Several approaches to enhance preservice teachers' diagnostic competence have already been undertaken in the field of science subjects (see e.g., Steffentorweihen & Theyßen, 2018;Tolsdorf & Markic, 2018). However, these studies do not identify how preservice teachers' learning processes are shaped concerning diagnosis and which factors influence diagnosis itself.…”
