This is the second of two the Designing to Support Learning sessions where participants think critically about designing learning experiences. In this session, participants focus on applying some of the insights and understandings they’ve gained in the course so far to the development of their activity with their partner. Participants are guided in the development of their designed activity using a COSIA Activity Design Starter, in an environment of support from their peers and instructors. This activity and design template helps them understand the complexity of designing activities to effectively address a science concept. They are guided to incorporate the pedagogy presented in previous sessions, including the learning cycle and effective teaching approaches, while designing their activity, to help learners come to some level of understanding of a science concept.
