This paper describes a department-wide deployment of DyKnow software to support collaborative note taking; classroom interaction; out of class review, replay, and grading of classroom materials; and computer monitoring. We describe diverse ways the software can be used to support computer science education and present the varied hardware environments (including standard laptops, Tablet PCs, interactive pen displays, and graphics tablets) that have supported the deployment. Results from surveys administered to 10 teachers and 81 students are presented. Collectively, these students have taken 431 classes using DyKnow tools. The survey results demonstrate the value students and teachers place on specific aspects of our approach and suggest areas for improvement.
