Secondary computer science teachers who attended a special institute took part in a coordinated team software development exercise. The exercise was intended to provide experiences with collaborative learning in computer science, particularly to provide project design experiences and to allow students to practice new methodologies that could be employed in their classrooms. This exercise also addresses many of the computer science competencies prescribed by the National Council for Accreditation of Teacher Education (NCATE). This paper provides an overview of the team project methodology and of its fulfillment of the NCATE guidelines. (Author/BEW)
