The purpose of this case study was to investigate how pre-service chemistry teachers' science teaching orientations change during a two-semester intervention designed to enhance their pedagogical content knowledge (PCK) for teaching the nature of science (NOS). Moreover, the way that pre-service chemistry teachers translated their change in orientation into both their instructional planning and their PCK was examined. Thirty pre-service chemistry teachers enrolled in a Research in Science Education course participated in the study. Responses to an open-ended instrument, interviews, observations, and documents such as lesson plans and reflection papers were used as qualitative data sources. Through in-depth analysis of explicit PCK and further deductive analysis, we identified the influence of the intervention on participants' orientation and how participants translated their orientation into their planning and PCK. Analysis of data revealed that most of the pre-service teachers' naive and transitional views about NOS changed into informed ideas after explicit-reflective NOS instruction. Participants revised their science teaching orientations by including more reform-based orientations at the end of the course (i. e., teaching NOS-related orientations). Their plans included at least one NOS aspect as an objective, which indicates that all of the participants designed their lesson plans with more informed views about at least one NOS aspect. In terms of aligning their reform-based orientations with other PCK components, pre-service chemistry teachers were more able to align their orientation with knowledge of instructional strategy and assessment than with knowledge of the learner. Implications for science teacher education and research are discussed.

The Investigation of pedagogical content knowledge of teachers : the case of teaching genetics Aydemir, Murat; Çakıroğlu, Jale; Öztekin, Ceren; Department of Elementary Education (2014) In this study science teachers’ content knowledge and pedagogical content knowledge (PCK) on genetics was investigated with respect to science teachers’ knowledge of curriculum, knowledge of students, and knowledge of teaching strategies. Five experienced science teachers (one male and four female) teaching genetics to 8th grades from five middle schools participated in the study. Case study, one of the qualitative research designs, was adopted as a research design. In order to gather information on content...
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...
Interaction between experienced chemistry teachers' science teaching orientations and other components of pedagogical content knowledge in mixtures Ekiz Kıran, Betül; Boz, Yezdan; Department of Secondary Science and Mathematics Education (2016) 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...
Development of pre-service chemistry teachers' pedagogical content knowledge for nature of science : an intervention study Demirdöğen, Betül; Kondakçı, Esen; Köseoğlu, Fitnat; Department of Secondary Science and Mathematics Education (2012) 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 fo...
Examination of interaction between pre-service chemistry teachers’ pedagogical content knowledge and content knowledge in electrochemistry Kutucu, Elif Selcan; Boz, Yezdan; Department of Secondary Science and Mathematics Education (2016) The purpose of this study was to examine the interaction between pre-service chemistry teachers’ pedagogical content knowledge (PCK) and content knowledge (CK) while teaching electrochemistry. Two pre-service chemistry teachers enrolled in practice teaching course in chemistry education program. All PCK components were studied in the current study to examine participants’ PCK. In order to get detailed information and understand deeply the interaction between CK and PCK, qualitative methodology was used and ...
