This study assessed the perceptions of adult learners in online distance learning programs regarding the instructional quality of Web-based courses via WebCT. The results showed an overall positive perception regarding the instructional quality of online courses delivered via WebCT (M = 3.51, SD = 1.1362). The mean obtained for students’ perceptions regarding the instructional quality items ranged from 3.7 to 3.37. The visual appeal of Web site and appropriateness of the course materials received the highest rating (M = 3.625). Clarity and purpose in introduction to content components earned the lowest ratings (M = 3.37). These results were closely correlated to students’ responses regarding the important aspects of instructional quality of online courses. The most important aspect indicated by students was the idea of having online course content and materials relevant to the course. The results of the study also indicated other perceived aspects that affect students’ views of the instructional quality of an online course, including interaction, design, convenience, feedback, and usability.
