The Just-in-Time Teaching (JiTT) methodology of Novak and collaborators (1999) uses web-based tools to gather student responses to content-specific questions on pre-class reading assignments. This approach defined a new and successful way to teach undergraduates physics. However, the technological requirements of JiTT and the content-specific nature of the pre-class questions may prevent some instructors or even entire institutions from implementing it. We present our own approach to JiTT, which uses publicly and freely available Web 2.0 technologies such as blogs and wikis and discipline-neutral pre-class questions. Our approach follows from our primary instructional objective of fostering deep, conceptual understanding of core course material, and from a set of five supporting objectives developed vis-à-vis Bransford (2000) and colleagues’ framework for the four “centrisms” contributing to successful learning environments.
