Objective: This study examined whether distributed practice could improve performance and attitudes in statistics, a subject that students report finding…

This study investigated how resource-demanding reading tasks and stressful conditions affect 1st-language (L1) and intermediate 2nd-language (L2) reading comprehension. Using the attentional control theory framework (Eysenck, Derakshan, Santos, & Calvo, 2007), we investigated the roles of central executive working memory (WM) resources,…

Online learning has gained importance in education over the last 20 years, but the well-known problem of high dropout rates still persists. According to the multi-dimensional learning tasks model, the cognitive (over)load of learners is essential to attrition when dealing with five challenges (e.g. technology, user interface) of an online training…

This study compared levels of statistics anxiety and attitude toward statistics for graduate students in on-campus and online statistics courses.
