In this workshop the participants will learn about the concept of pedagogical content knowledge (PCK) and how this concept relates to the preparation of physics teachers. PCK is what distinguishes a content expert from an expert teacher of that content. Some aspects of physics PCK include knowledge of student ideas in different areas of physics, knowledge of effective instructional methods that help students master fundamental physics ideas and ways of reasoning, and knowledge of assessment of student learning.  The participants will also learn how to design a course/a sequence of courses for future physics teachers where they start building their physics PCK.
