This paper presents research on the concept of idealized learning environments called Havens that facilitate learning, introduces the topic of technologically-created Havens, and discusses various components of Havens that can facilitate comprehension. Three experiments involving college students at Vanderbilt University are described. Designed to…

A computer-aided instructional system has been developed which utilizes dynamic computer-controlled graphic displays and which requires student interaction with a computer simulation in an instructional mode. A numerical scheme has been developed for digital simulation of a uniform, distortionless transmission line with resistive terminations and…

Describes five studies which investigate the effectiveness of computer use: (1) cost effectiveness in elementary school mathematics; (2) evaluation of computer use in a college chemistry course; (3) evaluating science software; (4) computer-videotape instruction in junior-secondary level mathematics; and (5) comparing microcomputers and flash card…

Describes study designed to investigate dental students' attitudes toward computer-assisted teaching as applied in programs for oral radiology in Denmark. Programs using personal computers and slide projectors with varying degrees of learner and teacher control are described, and differences in attitudes between male and female students are…

Three adaptive models encompassing variations of instructional support, incentives, and context of presentations were developed and validated through eight separate studies which compared the teaching of statistics under computer-managed instruction or teacher-managed systems. Results indicate instructional support adaptations were effective, but…

A study of eighth grade science students compared the instructional effectiveness and the cost effectiveness of an interactive video system with the use of 16mm films for teaching a science unit. Results indicated that interactive video can be significantly more effective than conventional methods of instruction. (eight references) (LRW)

Discussion of reading strategies focuses on a study of high school students that used three presentation modes via computer, with and without explanations about the value of text review. Highlights include pretests and posttests, student characteristics, test anxiety, prior knowledge, and implications for aptitude treatment interaction research…

Describes research with Dutch secondary school students that studied the effects of the presentation of more general (superordinate) concepts on the attainment of basic concepts, and the effects of two different forms of example presentation on concept learning. Computer based instruction and interactive video used in the study are described. (18…

This study compared the effects of chunking sentences on the retention and comprehension of two groups of learning disabled high school students, who received chunked reading via computer assisted instruction (CAI) or traditional methods. Both experimental groups performed better on the posttest than the control group, who received CAI without…

Describes study that examined the effects of combining word processors, spelling checkers, and spelling drill and practice programs to individualize spelling instruction for fifth- and sixth-grade students. Treatments for the experimental and control groups are explained, selection of software is discussed, and suggestions for software development…

Describes a study of 80 undergraduate foreign language learners that compared the use of a hyper-reference source incorporating an electronic dictionary and a conventional paper dictionary. Measures of consultation frequency, study time, efficiency, and comprehension are examined; bilingual and monolingual dictionary use is compared; and further…

Discussion of the educational effectiveness of textbooks focuses on a model of a virtual textbook that relies on hypermedia. Highlights include changing roles of teachers, students, and content; systemwide features of the virtual textbook, including interface and object-oriented design; classroom environment; sequencing; and a prototype. (Contains…

Discussion of various types of feedback used in computer-assisted instruction focuses on a study of low-ability eleventh graders that compared the effectiveness of answer until correct (AUC) feedback with knowledge of correct response (KCR) feedback. Achievement data on posttests as well as time data are analyzed. (11 references) (LRW)

This study examined the effectiveness of a computer algebra system in teaching secondary school mathematics. Pre- and posttest results and time on task were compared for students receiving conventional instruction and those receiving computer-assisted instruction using an enhanced version of muMath, a standard computer algebra package. (four…

Compares the performance of education undergraduates with high or low spatial-skill scores who learned how to calculate surface area using hypertext, computer-assisted instruction, conventional paper materials, or program control. Results are reported for misconceptions, correct problems, time on lesson, enjoyment rating, screens viewed, and…
