Web-based homework systems are becoming more common in general chemistry as instructors face ever-increasing enrollment. Yet providing meaningful feedback on assignments remains of the utmost importance. Chemistry instructors consider completion of homework integral to students' success in chemistry. This study compares the use of five Web-based systems to the traditional paper-and-pencil homework used over nine semesters in first-semester general chemistry. Data consisting of diagnostic pre/post-tests, GALT, and final semester grades are analyzed within the groups of successful and unsuccessful students. Statistically significant results suggest a chemistry instructor should carefully consider options when selecting a homework system.
