This study focuses on one particular aspect of usability, namely, user satisfaction, for an educational website used as a supportive tool for various courses by employing only one specific usability testing technique, a questionnaire. The researcher aimed to find out whether eighth semester undergraduate students of Computer Education and Instructional Technologies (CEIT) Department at the Middle East Technical University (METU) Ankara, Turkey, are satisfied with the website that is used as a supportive tool for a traditional classroom. Students enrolled in "CEIT 419 Internet for Teachers" undergraduate course were invited to participate in a study designed to understand the user satisfaction levels of a website used as a supportive tool for a course in a traditional classroom. The researcher administered the questionnaire during two hours of the ninth week of the semester due to the nature of the questionnaire, since the questionnaire is typically offered to users after they have completed a session of work with a particular system or program. Participants consisted of 33 out of 37 (30% female, 70% male) students ranging in age from 20 to 24 with a mean age of 22 (SD = 0.92). The researcher employed the Questionnaire for User Interaction Satisfaction (QUIS) based on OAI (Object-Action Interface) model, developed by Shneiderman in the Human-Computer Interaction Laboratory at the University of Maryland and refined by Norman and Chin (Schneiderman, 1998). The results of the study indicated that the users were initially impressed and satisfied with the website. Additionally, they found the website easy to use and powerful, in spite of the lack of flexibility and stimulating attributes of the website.
