Describes a study that implemented an Internet-based project in a Taiwanese secondary school biology class and investigated its effect on the cognitive preferences held by students and on their performance. Reports results of analyses of covariance that compared scores of short-answer questions, multiple choice items, and total final examination…

Investigated the effects of presentation format (animation, still graphics, text) and the students' prior knowledge on learning a computer-based physics lesson in grades eight and nine. Results of an analysis of covariance indicated that specific presentation formats are not equally effective for the different prior knowledge groups. (Author/LRW)

Describes a study that explored the effects of teacher-centered versus student-centered multimedia computer-assisted instruction on the science achievements of tenth-grade students in Taiwan. Results of analysis of covariance on pretests-posttest scores showed the teacher-centered approach was more effective in promoting students' science…

In 1980, Wichita State University received a grant to introduce microcomputers as interactive teaching tools in large science classrooms. Through this grant, 18 faculty in 11 departments developed software modules illustrating concepts that are often difficult to teach by usual lecture methods. To determine whether the use of microcomputers in…

Describes a study of ninth graders that investigated the effects of learner and program control over content review in science-related computer-assisted instruction (CAI). Results of posttests, continuing motivation measures, and attitude questions are discussed; and future research is suggested. (35 references) (LRW)
