Reflections of a First-Year Chemistry Teacher: Intersecting PCK, Responsiveness, and Inquiry Instruction.

Many educators agree that science instruction should be dominated by inquiry strategies, while others stress the need for responsive practices to place a focus on student learning and understanding. Some scholars believe the two approaches exist on opposite ends of an instructional spectrum, while others believe they may be aligned and intertwined. Pedagogical content knowledge (PCK), the broadly accepted gold standard for science education, seems to include both. Understanding how teachers incorporate inquiry strategies and responsiveness and how the two intersect could lead to a more complete framework for K–12 science instruction and help streamline science teacher education. This qualitative single-case study examined the reflections of a first-year chemistry teacher by exploring how she demonstrated responsiveness to students while maintaining a teaching orientation of inquiry-based instruction. Results indicated that responsiveness depended on a high level of PCK and led to higher or lower levels of inquiry based on the students' need for teacher support. Additionally, findings showed that the teacher's stated and demonstrated beliefs about inquiry were disconnected. Finally, a gap between science conceptual understanding and mathematics PCK suggested the need to support more innovative mathematics pedagogical strategies during physical science teacher education.
