Inquiry in Physical Science Education is a graduate-level professional development course. It is designed to enhance your understanding of inquiry-based approaches to teaching standards-based physical science at the high school level. In two sessions, you will investigate physical science topics and teaching methodologies using a wide range of online resources, including video segments, interactive activities, readings, and other multimedia materials. These resources are drawn from Teachers' Domain, WGBH's digital library service, which provides educational media to teachers and their students, for use in schools, libraries, and homes. The course provides an opportunity to explore novel learning environments and pedagogy applications that foster student interest, involve students in the research process, advance critical thinking/problem-solving skills, and develop conceptual understanding of physical science topics. It uses science inquiry, active learning, and curriculum design strategies to explore atomic structure, chemical reactions, motions and forces, the electromagnetic spectrum, and other important topics.
