Two theorems concerning F in analysis of covariance with two groups (experimental and control) and one covariable (pretest score) are presented. The first shows explicitly that F is a direct function of the ratio of the variance about the regression line for the total sample to the variance about the within-group regression line. The second…

Feuerstein's mediated learning theory was applied to a deaf population for investigating the cognitive modifiability of this population. The learning Potential Assessment Device (LPAD) was employed for determining transfer of learning along cognitive and behavioral dimensions. Results showed that the groups who received examiner mediation…

Maturation and education improve Air Force Officer Qualifying Test (AFOQT) scores. Since the AFOQT is given at different educational levels for the several commissioning programs, differences, largely spurious, exist between the programs. To assess differences produced by maturation and education, the AFOQT was given to 415 Air Force Reserve…

Using the Component Display Theory as an analyzing tool, this study compared the effects of expository and discovery methods of instruction on two learning outcomes, application and transfer. One hundred ninth grade students in each of four earth science classes were randomly assigned to five groups--four experimental groups designed to test four…

Describes research conducted with employees of the NCR Corporation that examined relationships between learning style preference, as measured by the Kolb Learning Style Inventory, and the effectiveness and acceptance of interactive video instruction to determine how best to individualize instruction. (13 references) (LRW)

Discussion of hypertext structures focuses on three studies of preservice teachers that assessed the effects of different methods of explicitly mapping expert knowledge structures onto hypertext on the acquisition of structural knowledge. Topics addressed include time on task, semantic networking, cognitive limitations of browsing behavior, and…

Describes a study of undergraduates that examined the effects of behavioral versus cognitive review strategies on learning outcomes and depth of processing during computer-based instruction. Near and far transfer learning are discussed, the use of locus of control is explained, and posttest differences are examined. (eight references) (LRW)

A study was made of the effects of programed instruction versus the use of course objectives and reference materials on learning, transfer, and attitudes in two adult experimental groups. The subject was mathematical concepts basic to introductory statistics. Mathematical tests and attitude scales were administered before and after the experiment.…

This investigation of the relationship of computer anxiety reduction to instructional strategies and learner characteristics used multiple repeated measures in a 2x2x2 quasi experimental design with arousal-seeking tendency, coping style, sex, computer skill mastery, and locus of control as the independent variables. Discrete dependent variables…

Describes study of undergraduates that investigated learners' preconceptions of the difficulty of interactive video, instructional television, and television. The effects of actively or covertly responding to practice questions on perceived mental effort, recall, and inferences are examined, and correlations between lesson time and inference or…

Describes the design and evaluation of a multimedia course on integrated circuit manufacturing that was developed at the University of California at Berkeley using IC-HIP (Integrated Circuit-Hypermedia in PICASSO), a hypermedia-based instructional system. Learning effects based on prior knowledge, methods of navigation, and other factors are…

This project was conducted in order to determine the practicality of using specialized videodisc instruction to help preservice elementary school teachers learn the Language Experience Approach (LEA) to teaching reading more effectively. Texas Tech University students enrolled in an interactive video course planned and produced the interactive…

Describes a study of undergraduate students that investigated the effects of two types of learner control and two types of incentives--task-contingent and performance-contingent--on learners' achievement, attitudes, use of options, and time on program using computer-delivered instruction. Implications for instructional design and research are…
