In this paper, we consider an online study program that isattended by students who mostly work full-time and therefore studypart-time. We investigate whether relationships can be found betweenstudents’ interactions in online courses of this program and their performancein courses. Though the study program and the courses are bothonline, their delivery through the learning management system (LMS)Moodle has not been designed to store comprehensive student interactionsautomatically. Therefore, we investigated whether the weekly regularityof students in the LMS is correlated to their performance in thecourse. Weekly regularity has been introduced in the context of MOOCs(Massive Open Online Courses) in [5]. We obtained inconclusive results.In only a few courses we could find a strong or moderate correlation. Weconjecture that this might be due to two factors: the limitation of ourdataset and the fact that, in the context of an online degree program,successful students do not necessarily access the learning material on aregular weekly basis.
