Although it is often assumed that the larger the bandwidth of the connection to the Internet, the better, few studies have actually been conducted to investigate the impact of various bandwidth connections on student performance in online courses. The goals of this study were to compare student online behaviors under different bandwidth connections and to investigate whether the type of course might be related to the impact of bandwidth for the behaviors. The present findings suggest that, while the use of "dial-up" versus "broadband" was related to some effects of behavioral differences, this relationship was not consistent across courses with different learning tasks. The study suggests that for online courses that are heavily learner-to-learner oriented, special considerations for students using dial-up access be considered.
