Digital lecturing systems (computer and projector, often with PowerPoint) offer physics instructors the ability to incorporate graphics and the power to share and reuse materials. But these systems do a poor job of supporting interaction in the classroom. For instance, with digital presentation systems, instructors have limited ability to…

In the past few decades, the physics teaching community has witnessed a surge in creative and often effective ways of using technology to improve physics instruction. Most of these findings suggest how technology can help instructors create interactive learning environments and how interactivity influences the effectiveness of physics learning.…

Presents techniques aimed at promoting a higher level of student-faculty interaction and active student participation in the learning process in introductory physics lecture classes. Discusses group problem solving, the use of flash cards, and assessment. (JRH)
