Immediate, Informative Feedback Using a New Homework System

Students often complain about the traditional homework system for inefficiency and lack of enough resources for help during the problems solving practices. The Physics Education Research Group at The Ohio State University is exploring a new homework system for introductory physics courses, in which students are given the solutions to their assignments before the due date. Each homework problem is also labeled with A, B or C to show the difficulty level as an additional feedback for students to evaluate their progress. We will report the outcome of this research and the effectiveness of this new system.
