John Farley (Physics) gave a departmental colloquium at the Missouri University of Science and Technology (formerly University of Missouri, Rolla) in October. Titled "Beyond the Lecture: What Have We Learned from Physics Education Research?," the colloquium examined how conventional lecture-based instruction is surprisingly ineffective in introductory physics classes. Students learn nearly twice as much when taught in a more interactive way, using "active learning," which also is called "interactive engagement."
