This research investigated the relationship between online students' behaviors in a learning management system and their learning performance, as measured by their final grades. Four online information technology classes in a major U.S. library and information science program were studied. The course sites' log data, as well as the students' final grades were analyzed at both the class level and the general level using the aggregated data from all four classes. The results show that the number of days students delayed in accessing weekly lecture materials had a significantly negative correlation with the final grade, while an increased number of discussion board postings had a positive correlation with the final grade. This correlation was significant on borderline, at p = 0.05 level. In one class an increase in the frequency of accessing the syllabus was significantly correlated with the final grade. The implications of the results are discussed. Based on the findings, suggestions on strengthening e-learning are proposed.
