In our research we investigate the use of online homework in principles of accounting classes where some classes required online homework while other classes did not. Users of online homework, compared to nonusers, had a higher grade point average and earned a higher grade in class. On average, both required and not-required users rated the online homework experience positively. Additionally, low-performing students appear to get more benefit than high-performing students from using online homework. Because of individual differences, no one study tool will be best for all students or in all situations. However, we conclude that use of online homework is an effective way to motivate students and may be particularly beneficial for less motivated or poorer performing students.
