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.…

Investigated the effects of group size and exposure time in the use of a commercially prepared tutorial program or drill-and-practice software by 168 fifth and sixth graders. Found that exposure time was related to students' scores on posttests. Results suggested a need to examine allocated time in microcomputer learning situations. (LB)

Discussion of multimedia instruction focuses on a pilot study that compared the relative effectiveness of three interactive media formats in a DVI/RTV (Digital Video Interactive/Real Time Video) computer-mediated instructional lesson for a military communications system. Hypotheses tested are discussed, and the educational importance is…

Introduces an interactive distance learning environment prototype developed jointly by Rensselaer Polytechnic Institute (RPI) and AT&T which allows students to participate in virtual classroom environments by using computer teleconferencing. Student collaboration, note taking, question answering capabilities, project background, learning…

Argues that acquisition of computer technology by public schools will make entrepreneurs and bankers rich without improving educational quality. Evidence of commercial interest in promoting technology and educator interest in acquiring technology is given. Comparisons of educational achievement in America and other countries and suggestions for…

Reports on a study of the influence of problem-solving computer software on the attitudes of secondary school students toward mathematics while using computer-assisted instruction. Student performance on pretests and posttests are compared, gender differences are discussed, and implications for mathematics instruction are suggested. (10…

This metanalysis reviews 32 studies that compared 2 groups of students receiving identical writing instruction, with only 1 group using word processing for writing assignments. Word processing improved the quality of student writing but did not improve student attitudes. Suggestions are given for using word processing more effectively. (SLD)

Explains the combination of hypertext and knowledge maps into hypermaps, and describes a study of undergraduates learning statistical material that compared the effectiveness of using hypertext versus hypermaps. Recall, reference time and accuracy, and student satisfaction are investigated, and needs for further studies are suggested. (10…

Discussion of the use of computer networks to create electronic communities highlights a research strategy that compared educational activities conducted across electronic networks to examine features of successful and unsuccessful electronic communities. Networks described include university researchers' networks; teacher networks; student…

Discussion of peer-based collaborative learning focuses on two related studies: a micro-structure comparative analysis of students' psycho-social behaviors in computer-based collaborative learning experiments conducted in face-to-face and distributed learning environments; and an examination of cognitive effects of peer-based collaborative…

Describes the design of a hypermedia tool for helping preservice teachers learn about the growth and development of children's mathematical reasoning based on research in cognitive science, and discusses results of an experiment that used single-subject methodology to compare preservice teachers' learning with the hypermedia tool versus learning…

Describes a study of ninth-grade students that evaluated the ability of the Word Problem Solving Tutor, a cognitive tutoring system, to improve the abstract-reasoning component of word-problem solving. Compares combinations of traditional instruction, computer-assisted instruction, and the tutoring program and discusses implications for math…

The authors examined the efficacy of Web-assisted instruction for promoting the use of social cognitive theory (SCT) strategies related to physical activity. They recruited college students attending health courses. The authors created 3 groups (Web-assisted, comparison, and control) based on the course structure. The Web-assisted group received…

This study was conducted to assess the effectiveness of two programs developed by the Frostig Center Research Department to improve the reading and spelling of students with learning disabilities (LD): a computer Speech Recognition-based Program (SRBP) and a computer and text-based Automaticity Program (AP). Twenty-eight LD students with reading…

This study examined the factors that contribute to learners' perceptions of the ease or difficulty of learning a specific task using a specific medium were studied, specifically whether the preconceptions of preservice teachers vary by learning domain (verbal, intellectual, affective, and psychomotor) or medium of presentation (interactive video,…
