This seminar accompanies mentored student teaching field placements in a PreK-6 classroom with computer science (CS) content. The course addresses aspects of classroom practice as related to CS instruction at various levels, including teaching and management, the delivery of CS content and planning strategies that address the needs of all students, especially students with disabilities and emergent bilinguals. In addition, the course helps pre-service teachers develop productive habits of planning and reflecting on the teaching and learning of CS.
