Two studies examined effects of computer-assisted (CA) teaching methods in introductory psychology classes. In Study 1, we provided students with lectures supplemented with either overhead transparencies or CA visuals. In Study 2, we compared students who used an optional Web site with students who did not. In both studies we held constant lecture content, course instructor, exams, and assignments. Results of the two studies showed that students liked the CA teaching interventions, although CA instruction had no effect on student performance in the courses. Based on these and other published findings, we recommend that universities examine closely their goals and priorities when devoting resources to instructional technology.

To test the effectiveness of an online introductory psychology course, we randomly assigned students to a large, traditional course or to an online course from a population of students who indicated that either course type was acceptable using a "waiting list" experimental design. Students in the online course performed better on exams and equally well on paper assignments compared to students in the traditional course. Online students also showed greater satisfaction with the course than those in the traditional course. Our results indicate that students who are amenable to taking either an online or a traditional course performed as well in an online course as students enrolled in a large, traditional course.

In this article, we describe and evaluate a Web-based interactive tutorial used to present hypothesis testing concepts. The tutorial includes multiple-choice questions with feedback, an interactive applet that allows students to draw samples and evaluate null hypotheses, and follow-up questions suitable for grading. Students either used the interactive tutorial (n = 15) or completed a standard laboratory assignment (n = 10) covering the same topics. Students who used the tutorial performed better (p =.06) on a quiz than students who completed the standard laboratory, supporting the effectiveness of this freely available online tutorial. A second group of students (n = 112) who did not participate in the assessment overwhelmingly rated the tutorial as easy to use, clear, and useful.

College students (134 women and 55 men) participated in introductory psychology courses that were offered largely online (on the World Wide Web) or in a lecture format. Student comprehension skills were inferred from their scores on a multimedia comprehension battery. The learning of content knowledge was affected interactively by comprehension skill level and course format. Differences between format increased with comprehension skill such that the Web-based course advantage became greater as comprehension skill increased. This same pattern was not seen when self-reports of comprehension ability were used as the predictor. Furthermore, comprehension skill did not predict course satisfaction. Generally, students of all skill levels preferred the lecture courses.

We offered introductory psychology on the World-Wide Web (WWW) and evaluated the on-line format relative to the traditional lecture-test format, using a pretest-posttest nonequivalent control group design. Multiple sections of the introductory course were offered each semester; on-line and lecture sections were taught by the same instructor, the same textbook was used, and the same in-class examinations were taken. For on-line sections, mastery quizzes, interactive individual exercises, and weekly laboratory meetings replaced lectures. Increased content knowledge was greater for the students in the Web sections, as was in-class examination performance. Use of the WWW and computers for academic purposes increased more in the on-line sections, and the on-line students showed a greater decrease in computer anxiety. The students in the on-line sections expressed appreciation for course components and the convenience of the course, but the lecture sections received higher ratings on course evaluations than did the on-line sections. Learning and course satisfaction were dissociated in the two course formats.
