Teaching Philosophy

The CORAL group believes that classrooms should provide places where students have the opportunity to be learners "actively working" together on specific learning objectives in a team environment. Thus a collaborative work team advocates commitment to working together, understanding individual and team autonomy, defining purpose of teams objectives, learning how to use distributed leadership and negotiations skills, defining team norms and codes of conduct, developing member roles for task completion, nurturing sub-groups, and allowing for members to resolve their own disputes. I developed the CORAL model as a "student / faculty partnership" focusing on a learning project utilizing the Internet as a collaborative tool connecting university-level students in varied disciplines and at distant sites to complete an applied joint (collaborative) project. We utilize students as 'Peer Mentors' (I call them Project Guides) in teaching 'Peers' how social constructivism is utilized to emulate the workplace environment.
