|Scharfenberg, F-J; Bogner, FX: A New Role-Change Approach in Pre-service Teacher Education for Developing Pedagogical Content Knowledge in the Context of a Student Outreach Lab., Research in Science Education, 46(5), 743–766 (2016) [Link]|
How pre-service teachers (PST) develop pedagogical content knowledge (PCK) during science teacher education is an open research question. Our teacher-education module, theoretically based on PCK, specifically combines biology PSTs’ education with high school students’ biology education and includes an innovative role-change approach. Altogether, 41 PSTs each participated in three subsequent module days with students of 50 classes (N = 823). The module’s content dealt with the syllabus topic Genetic Fingerprinting. During participation, the PSTs changed their role by assuming a student’s role on the first day, a tutor’s role on the second day, and a teacher’s role on the third day. By quasi-experimentally administering pre- and delayed posttests, we qualitatively monitored, then content-analytically categorized, and finally quantitatively analyzed three specific PCK components. In contrast to a control group (which did not participate in the module), our treatment preferentially changed the PSTs’ orientations toward teaching biology to a more student-centered orientation (both intra- and inter-group differences with medium effect sizes). Additionally, our treatment PSTs differed before and after module participation in how they addressed potential student learning difficulties and identified potential instructional strategies for avoiding these difficulties. The changes in these PCK components point to a step-by-step development of the PSTs’ PCK. In this process, our participating PSTs assessed the importance of their three roles on the three days quite differently; most notably, we found one relationship between the teacher role and the PSTs’ student centeredness. We specifically discuss the potential and importance of our role-change approach within science teacher education.
