This study aims to compare the effectiveness of case-based instruction over traditional instruction in improving 11th grade students' understanding of electrochemistry concepts, attitudes toward chemistry, chemistry self-efficacy beliefs, and motivation to learn chemistry. In total, 113 students (47 males and 66 females) from three high schools participated in this study. Two of the classes from each school were randomly assigned to be either the experimental or control group. The experimental g...

This study combined two important frameworks—teacher self-regulation and pedagogical content knowledge (PCK)—to reveal whether they were related to each other. To fulfill this aim, researchers utilized a case-study design. Data were collected from five preservice chemistry teachers through semi-structured interviews, lesson plans in the form of content representations, and video recordings of teaching practice. Both deductive and inductive analyses were used to analyze the data. Results indicate...

In this self-study, we aimed to delve into how re-designing and teaching re-designed practicum course offered to pre-service teachers (PTs) enriched our, as science teacher educators, development of pedagogical content knowledge (PCK) for teaching science teachers. This self-study was conducted during a compulsory practicum course in which we served as teaching assistants (TAs). The qualitative data collected through journal entries written by the help of mentoring experience, Content Representa...

Abstract This secondary analysis study focused on how interactions among preservice teachers' pedagogical content knowledge (PCK) components developed throughout a 14-week CoRe-based mentoring-enriched practicum course, and the nature of those interactions. Data were collected from three preservice teachers, information-rich cases, by the use of content representation (CoRe) and semi-structured interviews. Content analysis and the constant comparative method were employed in the data analysis. R...

The purpose of this research was twofold. The first was to investigate the development of preservice teachers’ knowledge base for science teaching on the rate of reaction topic within the 14-week content representation (CoRe)-based mentoring-enriched practicum course. In this course, CoRe design was used as a form of lesson planning and intensive educative mentoring was provided by teaching assistants. The second purpose was to identify which aspects of the practicum course contributed to preser...

This study investigated pre-service chemistry teachers' pedagogical content knowledge of the nature of science (NOS) in the content of the particle nature of matter. Qualitative research design was utilized. Data were collected from seven pre-service chemistry teachers (PCTs) by using open-ended questions, interviews, observations, lesson plans, and reflection papers. The results indicated that while most of the PCTs showed improvement in terms of understanding of the target aspects of NOS, know...

The purpose of the present study was to adapt the Sources of Self-Efficacy Inventory (SOSI) into Turkish. The scale was developed by Kieffer and Henson (2000) for teachers considering four sources of selfefficacy proposed by Bandura (1997) which are mastery experience, vicarious experience, social persuasion, and physiological and emotional states. In the pilot study, the scale was administered to 256 pre-service teachers and then revised based on the results of confirmatory factor analysis. In ...
