The Physics Education Research Group at the University of Maryland has been conducting research of student understanding in physics. We have investigated student understanding of mechanical waves in our calculus-based physics courses. Our methods include the analysis of free response conceptual questions, examination questions, and interviews with the students. Examples of our results include student difficulties with the speed of waves and with superposition. Based on this research, we have developed new, student centered instructional materials using interactive video tools on the computer.
