This study examined whether sociocontextual and sociocognitive variables explained the math/science goals of 409 Mexican American youth using a modified version of R. W. Lent, S. D. Brown, and G. Hackett's (1994) social cognitive career theory. Results from structural equation modeling indicated that the hypothesized model explained a significant…

This article addresses the problem of ascertaining the most suitable learning environment for learning diagnostic skills in health education--specifically diagnostic reasoning and the selection of therapy--through the design, development, and evaluation of a videodisc program. It describes the design, development, and formative evaluation of a…

This study was designed to gain a better understanding of interactive video instruction and its effects on individual learning in high school students in Taiwan. The study had three objectives: (1) to identify students' background information and involvement in computer assisted instruction; (2) to assess whether there is a linear relationship…

Introduction: A number of theoretical works focus on the potential revolutionary impact of the Internet and other Information and Communication Technologies (ICT) upon Competitive Intelligence, but only a few empirical research papers can be found on it. Is the real impact still unknown, or is it too insignificant to talk about? The present paper…

This study of the role which learner control plays in the success of interactive courseware (ICW) was designed to determine whether providing students with an option to review content in ICW--when attempting to answer embedded questions--improves their achievement on a posttest without adversely affecting the amount of time it takes to complete…

A study was carried out at Pennsylvania State University to examine the effects of both textual and computer animated orienting activities--i.e., mediators through which new information is presented to the learner--and practice on the application and problem solving skills of elementary school students. It was hypothesized that students provided…

Two studies were conducted to compare the advance organizer and concept elaboration models of instruction with a task analysis approach. It was hypothesized that the concept elaboration group would achieve significantly higher than either the advance organizer group or the task analysis group on concept learning and principle learning. A pilot…

The rule space model permits measurement of cognitive skill acquisition, diagnosis of cognitive errors, and detection of the strengths and weaknesses of knowledge possessed by individuals. Two ways to classify an individual into his or her most plausible latent state of knowledge include: (1) hypothesis testing--Bayes' decision rules for minimum…

The Memphis Apple Classroom of Tomorrow (ACOT), one of seven ACOT locations, was a joint project of the city schools and Apple Computer. The ACOT consisted of a class of 30 fifth grade students in an inner city school, who were selected on the basis of the willingness of the students and their parents to participate and to use computers in the…

This paper evaluates the logic underlying various criticisms of statistical significance testing and makes specific recommendations for scientific and editorial practice that might better increase the knowledge base. Reliance on the traditional hypothesis testing model has led to a major bias against nonsignificant results and to misinterpretation…

This study assessed the effect of group size and presentation mode on acquisition of the process skill of forming and testing hypotheses and selected attitudes. Preservice elementary teachers (N=87) in five intact classes received two 1-hour sessions presented by microcomputer, 1 week apart. Half of the subjects were assigned to three-member…

Data drawn from 30 journal articles and ERIC documents reporting on gender differences in natural science achievement were re-examined. Three meta-analysis methods were used: (1) vote counts and vote-counting estimation procedures; (2) tests of combined significance; and (3) analyses of effect sizes. The three methods produced seemingly…

Some examinees' test-taking behavior may be so idiosyncratic that their scores are not comparable to the scores of more typical examinees. Appropriateness indices, which provide quantitative measures of response-pattern atypicality, can be viewed as statistics for testing a null hypothesis of normal test-taking behavior against an alternative…

Learners at primary level had learning impediments in divisions of mathematics, which was eliminated by a student mentor's kind approach, conducive motivation, spot guidance, friendly facilitation and guidance to achieve required competency. Hence the student mentor can motivate the learners to achieve the expected learning outcomes in stipulated…

Fifty-eight studies relating to the "knowledge gap" hypothesis (a theory that correlates public knowledge to educational level and mass media exposure) are examined in this report. In the opening sections, the theory is defined, and the early information diffusion studies and public opinion polls that led to its formulation in 1970 are…
