Homework gives students the opportunity to practice new skills in both familiar and unfamiliar situations, and to develop an understanding of related concepts. Although some of these goals can be easily accomplished in online homework, many systems are less useful for handling open-ended questions. Written homework, on the other hand, takes time to grade and delays feedback. To fill the gap left between these approaches in lower-level courses, I supplement online homework with "homework presentations." Students put worked problems up on the board to earn points, and we discuss the problems together. In addition to reducing grading load, homework presentations provide students with feedback at the optimal place in the learning process.
