Internet Learning Journal that the majority preferred print course materials to electronic course materials (Baron, 2016 as cited in Schaub, 2016). Margolin, Driscoll, Toland, and Kegler (2013) presented undergraduates with electronic and print versions of narrative and expository passages and then measured reading comprehension. While the study found no significant difference in reading comprehension for the two formats, Margolin et al. suggest that additional research is needed to examine if resource format affects reading comprehension of informational passages. Studying a general education psychology course, Shepperd, Grace, and Koch (2008) did not find a difference in course grades for students using a physical versus electronic text. Similarly, a multi-institutional study found that across courses in four disciplines, student performance was similar in courses using OERs versus traditional resources (Fischer, Hilton, Robinson, & Wiley, 2015). Measuring undergraduate student experience retaining information from print and electronic presentations, Green, Perera, Dance, and Myers (2010) found no difference in reading comprehension and information recall between the two mediums. In contrast with these studies, other research suggests that student performance may be reduced when using electronic materials. For example, Ackerman and Goldsmith (2011) found that in untimed assessments, college students who had print versions of reading materials performed better on comprehension and retention tasks than students who had electronic reading materials. Study Overview In this study, we build on earlier research examining the effect of print and electronic course materials on reading comprehension and retention (Ackerman & Goldsmith, 2011; Baron, 2016 as cited in Schaub, 2016). This study examines if the type of course materials (electronic, print) is related to undergraduate student performance in an online course at an online institution serving adult learners. Adult learners in online courses tend to approach learning with a high degree of self-motivation, autonomy, and motivation to relate new learning to prior experience (Conaway & Zorn-Arnold, 2016). In this completely virtual environment, students are accustomed to an online learning experience, including asynchronous delivery of course content and participation. Thus, students may be more comfortable and agile with electronic reading. At this institution, undergraduate students also receive course materials as part of the program cost, meaning that all students have access to the course materials. We predicted that students who received electronic course materials will have equal levels of reading comprehension and retention, demonstrated through their performance on assessments, compared with students who received physical course materials. Methods This study examined undergraduate students in a high enrollment, introductory level online 6
