Physics Illuminations: Supplementing Instruction via Web-Based Self-Study

Gaining conceptual understanding of physics is difficult for many students. Interactive engagement classroom techniques have been shown to help alleviate this problem. This paper describes progress in addressing the problem from a different direction – that of students’ out-ofclass study. Results from investigations employing several commonly-used assessment instruments indicate that out-of-class study time can indeed be utilized to improve student learning of basic physics concepts.
