Wikis have been used in a myriad of innovative ways to enhance learning at Columbia University. This session will focus on how wikis can be used effectively to teach foreign languages, conduct object/art analysis, and write multimedia essays. A wiki can also be used as a platform for Web 2.0 tools such as mapping and tagging. CCNMTL staff will present an array of examples from Columbia courses and Professor Jutta Schmiers-Heller will present challenges and successes of using a wiki to teach German language courses.
