Two variables that designers should consider when developing computer-based instruction (CBI) text screens are text density, which manipulates the context of the information presented, and screen density, which is a measurement of the amount of information presented at one time on the screen. A study on text density was designed to identify…

Reports on a descriptive study of the effects of remoteness on the attitude levels of secondary school students taking audiographic teleconferencing courses. Attitudes of students taking courses on site with a teacher were compared to those of students taking the courses at remote locations. No significant differences were found. (52 references)…

Sixth graders (n=124) were tested for their perceptions of self-efficacy with print and TV, perceived media realism, and attributions of failure and success with each medium. The amount of invested mental effort (AIME) and achievement were measured. The roles of a priori perceptions and AIME in learning are discussed. (Author/BS)

Although some aspects of the educational effects of computer assisted instruction (CAI) are still unclear, some research findings are now quite definite. Two meta-analysis reviews of CAI have been completed at the University of Michigan, one on secondary school teaching and one on college teaching, and their findings have been independently…

Student attitudes were investigated in an attempt to determine systematic attitudinal differences among various types of instructional control. Ninety-nine undergraduate students from a basic educational media course volunteered for this study. Six interactive video lessons--covering basic technical aspects of 35 millimeter photography--were…

The level of abstraction of the message and the educational effects of five media presentations (Print, verbal sound, print/pictures, print/verbal sound, and pictures/verbal sound) were experimentally investigated. The media components were presented singly or in combination to 6th grade students in a uniformly controlled consistent environment.…

This discussion of research on media influences on learning describes a study of 611 students, grades three through 10, that examined user preconceptions about learning activities; examined differences in preconceptions across demographic subgroups based on gender and grade level; and interpreted results according to a theoretical learning model.…

Describes study that investigated the effects of medium of instructional practice, task difficulty, and gender on continuing motivation. Microcomputers and paper and pencil format were compared on tasks at a hard or easy difficulty level with fifth and sixth grade students, and questionnaires were used to determine student attitudes.

A critical process in developing lessons for computer-based instruction (CBI) is to determine the manner in which information will be displayed on the screen, taking care not to ignore the computer's special display capabilities. The underlying assumption of this study was that reducing the density of text presentation would be effective for…

Research evaluated captioned educational films for the deaf for possible use in classes with normal hearing slow learners. Specifically, the project sought to determine the effects of captioning on attention, vocabulary level and reading ability, using conjugate reinforcement as an evaluation procedure. The results indicated that, under certain…

This meta analysis of 101 studies of computer-based education in colleges highlights examination performance, student attitudes toward instruction and computers, the relationship of publication source to study outcome, and time needed for instruction. One hundred twenty-one references are listed. (Author/LRW)

This metaanalysis of 32 comparative studies shows that computer-based education has generally had positive effects on the achievement of elementary school pupils. However, these effects are different for off-line computer managed instruction and interactive computer assisted instruction (CAI); interactive CAI produces greater increases in student…
