Developing Pre-Service Teachers’ Pedagogical Content Knowledge: Lessons from a Science Methods Class

A citizen’s ability to thrive in today’s technologically advanced society necessitates robust and nimble scientific literacy. The development of such literacy is rooted in science instruction that engages students with appropriate cognitive tools that enable active knowledge construction through scientific practices. One such instructional approach with proven positive science learning outcomes is project-based learning. However, little is known about future teachers’ takeaways from participation in project-based learning science methods courses and how those takeaways connect to teachers’ developing pedagogical content knowledge. In this qualitative study, we examined pre-service teachers’ end-of-semester reflective blogs and identified the main themes and connections to the five dimensions of pedagogical content knowledge (PCK). Across three cohorts of pre-service science teachers, we found nine common themes connected to the four dimensions of PCK that involve teachers’ orientations towards science teaching, their knowledge of science curricula, instructional strategies, and students’ understanding of science. We found no prominent connections to the dimension that emphasizes a teacher’s knowledge of the scientific literacy assessment. These findings suggest the asymmetrical development of pre-service teachers’ PCK. Teacher educators should explicitly address the scientific literacy assessment and support pre-service teachers as they develop their knowledge of it. We discuss additional implications for research and practice.
