In this professional development video, Liberty High School physics teacher Tim Lamb takes steps to explain a fundamental principle that is often confusing for students: the difference between mass and weight. As the lesson begins, Tim uses a student responder tool to assess students’ prior knowledge and beliefs about weight and mass. Based on that data, he provides direct instruction and poses questions to guide student thinking. Importantly, Tim actively encourages students to engage in social constructivism, a process by which students construct meaning by solving problems together in collaborative groups.
