The purpose of this study was to delve into the complexities of development of preservice chemistry teachers’ science teaching orientation, knowledge of learner, knowledge of instructional strategies, and knowledge of assessment during Pedagogical Content Knowledge (PCK) for Nature of Science (NOS) instruction. Thirty pre-service chemistry teachers enrolled Research in Science Education course participated to the study. Case study, one of the qualitative research methods, was used as research design. PCK for NOS instruction spanned two semester weeks including learning NOS, explicit-reflective, and learning how to teach NOS, addressed four PCK components, parts. This study only involved the collection of qualitative data sources including responses given to an open ended instrument, interviews, observations, and documents such as lesson plans and reflection papers. In-depth analysis of explicit PCK and constant comparative method were used as data analysis methods. Results revealed that most of the pre-service chemistry teachers had naive and transitional views about NOS. However, they had informed view after explicit-reflective NOS instruction. Although all participants developed PCK for NOS in some extent and nevertheless the participants’ PCK for NOS were different from each other in terms of both the degree of integration among the components and the degree to which these components and connections manifest themselves in their lesson plans and reflection papers. Moreover, there was no clear relationship between the participants’ NOS understandings and their PCK for NOS whereas most of them attempted to teach NOS aspects that they had informed views

Investigation of pre service science teachers perceptions related to pedagogical knowledge and pedagogical content knowledge
Güler, Fulden; Aksu, Meral; Department of Educational Sciences (2015)
The purpose of the present study was to investigate the pre service science teachers’ perceptions related to science teaching. Within this scope, participants’ perceptions related to their pedagogical knowledge (PK) and pedagogical content knowledge (PCK) were examined. Furthermore, it was aimed to investigate the effect of gender and level of achievement on participants’ perceptions regarding PK and PCK. 176 fourth year pre service science teachers from three state universities of Ankara participated in th...

The purpose of this study was twofold: The first one was to investigate all components of experienced chemistry teachers’ pedagogical content knowledge (PCK) which are science teaching orientations (STO), knowledge of learner, knowledge of curriculum, knowledge of instructional strategy and knowledge of assessment, and the second one was to examine the interactions between their science teaching orientations and the other components of PCK. Two experienced chemistry teachers participated in the study and th...
Use of learning trajectories based instruction to restructure pre-service elementary teachers’ mathematical content and student knowledge
Yılmaz, Zuhal; Haser, Çiğdem; Department of Elementary Education (2015)
The purpose of this study was to explore elementary pre-service teachers’ (PTs) mathematical content knowledge (MCK) and student knowledge (SK) restructuring practices for equipartitioning related mathematical ideas. Nine senior PTs from a private university located southeastern part of the Turkey were voluntarily participated to Learning Trajectories Based Instruction (LTBI) teaching experiment. Classroom video data, written works of PTs, pre-post tests and field notes were the main sources of the data col...
