Neelu Sinha, Laila Khreisat, and Kiron Sharma describe how learner-interface interaction promotes active learning in computer science education. In a pilot study using technology that combines DyKnow software with a hardware platform of pen-enabled HP Tablet notebook computers, Sinha, Khreisat, and Sharma created dynamic learning environments by integrating classroom and computing environments. Results of the pilot study indicate that the learner-interface interaction provided by this versatile learning environment, which is based on a hands-on approach with real-time feedback, has enabled active learning for face-to-face computer science courses from introductory to advanced levels. These new technologies facilitate the creation of a nonthreatening, flexible, and challenging learning environment with a focus on practical applications, potentially narrowing the perceived gap between theory and practice in computer science education and aiding in student and teacher recruitment and retention.
