Describes mechanisms of thought associated with making predictions. Concludes that successful predictors had high initial knowledge of the subject matter and were formally operational. Unsuccessful predictors had low initial knowledge and were concretely operational. Systematic manipulation, note taking, and higher-level thinking skills were…

This paper reports estimates of the distribution of individual private rates of return to undergraduate and community college education by field of study for Canada. It is important to know the dispersion of the private rate of return to post-secondary education, as well as its average level. There are very different implications for…

Inconsistencies in scores from computer-simulated and "hands-on" science performance assessments have led to questions about the exchangeability of these two methods in spite of the highly touted potential of computer-simulated performance assessment. This investigation considered possible explanations for students' inconsistent performances: (1)…

This paper discusses the role of high school chemistry teachers' beliefs in implementing computer visualization software to teach atomic and molecular structure from a quantum mechanical perspective. The informants in this study were four high school chemistry teachers with comparable academic and professional backgrounds. These teachers received…

Discussion of instructional visuals and practice techniques as effective learning strategies focuses on a study of undergraduates that examined the effects of animated instruction and practice on adult learning in a computer-based science lesson. Analyses of the results indicate that practice affects performance measures more than visual…

Describes a study designed to assess the effectiveness of 2 science simulation programs for 11- and 12-year-olds in a developing country (Guyana). Computer-assisted learning (CAL) results are compared with results from written assignments, effect size is discussed, gender differences are examined, and ability levels are considered. (14 references)…

Reports on a program developed in Indiana public schools to hold software evaluation workshops that would compare teacher and student evaluations of the same software. The evaluation process is discussed; tutorials, drill and practice programs, simulations, and games are examined; and tests for correlation are described. (21 references) (LRW)

A regression model of teacher stress was evaluated through the use of LISREL models at six selected points in time over an autumn term for 142 grade 1 through 12 teachers. Home environment and relations with colleagues and students were significant factors at various times throughout the study period. (TJH)

Describes a study conducted at the University of Iowa College of Dentistry that compared the effectiveness and efficiency of adaptive instruction with nonadaptive instruction using interactive videodisc patient simulations. The Dental Diagnosis and Treatment (DDx&Tx) System is explained, and problem-solving skills and study time are discussed.…

Developed is an examination to determine a student's visualization capabilities. This examination has two versions, both developed to measure visualization ability, time to visualize, and reaction time. This test indicates the learner's ability to visualize complex three-dimensional objects from six principal views. Included are the results from a…

Describes a HyperCard-based simulation/tutorial for the Macintosh that is designed to teach users to search the Medline CD-ROM database on an IBM microcomputer. Results of a user survey are reported, and the potential of HyperCard for bibliographic instruction, including the use of the tutorial to develop transparencies, is discussed. (MES)

Describes a computer-based clinical simulation for medical education that incorporated problem-based learning and reports on a field-based study that implemented this approach with first-year medical students. Questions designed to bridge the gap between clinical skills and conceptual science knowledge provided a context for collaborative…

This study examined the psychometric properties of performance measures for three novel, interactive virtual reality vignette exercises developed to assess social competency skills of at-risk adolescents. Performance data were collected from 117 African-American male 15-17 year olds. Data for 18 performance measures were obtained, based on…

In this paper, ULearn (University of Surrey learning on-line) and e-learning techniques are used to enhance the students' understanding and participation in Dynamics modules for an undergraduate programme in the School of Engineering, University of Surrey. The Dynamics modules are taught at Levels 2 and 3 and contain several mechanisms and…

The purpose of this study was to investigate the effects of using individual, cooperative-dyad, and collaborative-dyad learning structures with a computer simulation. College students implemented and experienced one of the three learning structures while using a computer simulation designed to teach the technical and procedural aspects of…
