The purpose of this study was to improve the pedagogical content knowledge (PCK) of pre-service chemistry teachers using a school experience course enriched with PCK development tools such as CoRe as a lesson planning form, observations of mentor teachers' teaching by using an observation form prepared based on PCK components, discussion sessions…

In this convergent-parallel mixed-methods study, we explored the effect that teaching remotely during the first months of the pandemic had on teachers' TPACK and how teachers leveraged their new and existing knowledge to facilitate remote instruction. Survey results indicated that teachers' self-reported knowledge decreased across multiple TPACK…

Pedagogic Content Knowledge (PCK) is variously considered a useful framework, construct, model and tool to both understand and help form the knowledge base for teaching. There exists extant literature on the PCK of science. Building on this literature, this study aims to contribute towards an understanding of implementing curriculum reforms in…

In this paper, we report on changes to teachers' knowledge and practices as a result of their participation in a professional learning initiative focused on cognitively challenging tasks and the pedagogies for enhancing student reasoning as such tasks unfold.
