The purpose of the two experiments was to investigate the potential effects of different types of visualizations and self-explanation prompts on learning human cardiovascular system in a multimedia environment. In Experiments 1 and 2, 70 and 44 college students were randomly assigned to one of the four conditions in a 2 × 2 factorial design with…

Describes the process used to develop two examinations, an achievement test of computer literacy and a computer anxiety index. Highlights include a definition of computer literacy, determination of the validity and reliability of the tests, and a study to evaluate the final versions of the tests. (Author/LRW)

Examines effects of overview mode and computer experience on achievement, attitude and instructional time in a hypertext learning environment. Results indicated participants with high computer experience learned more from the program than those with low experience. Participants receiving structured or unstructured overview spent significantly more…

Exploration of concepts crucial to development of new computer-based learning environments focuses on process rather than product and the computer's ability to record, represent, and communicate the underlying process. Cognitive, pedagogical, and sociological issues relevant to creation of learning environments in five domains (empowering…

Describes study that was conducted to determine whether four- and five-year-old preschoolers could be taught reading skills with computer-assisted instruction, and whether they could learn basic computer literacy skills without direct instruction and drill. Software is described, and the pretest/posttest single group design is explained. (16…

Conducted to determine whether use of computerized file-management programs can enhance the development of information processing skills, this two-treatment experiment found that seventh through twelfth grade students in the computer-using/structured activities group received significantly higher mean scores than the…

Discusses the current plan to introduce computer literacy into Soviet schools; examines the resources needed (hardware, software, personnel) to carry out the plan; examines the directions Soviet research on educational applications of computers is likely to take; and looks at factors that may influence the success of the program. (EM)

Presents methods and outcomes of a semester-long course involving cooperative hypermedia authoring and instructional strategies for preservice teachers. Posttest findings revealed that participants showed a decrease in computer anxiety through their involvement in the course, and the lowest levels of anxiety were associated with graduate rank and…

Data from a national survey of microcomputer uses in schools are used to demonstrate differences in access to and uses of computers by students. Factors examined include race, socioeconomic status, sex, achievement, and ability level. Also discussed are inequality and inequity and the need for additional research on computer impact. (RP)

A study of 50 students (grade 9) enrolled in a computer course found that home computer access for females was a predictor of early success for using computers as a learning resource and that enrollment in a computer course was greater for females who had access to home computers. Initial advantages diminished with continued use of computers. (PEN)
