Discussion of the use of nonexamples as an effective strategy in teaching concepts focuses on a study of college students that explored the use of common errors to teach the procedure for color correction of color transparencies. Treatments for the experimental and control groups are described, and further research needs are indicated. (Author/LRW)

Two studies investigated robustness of the effect of precise elaborations on memory and relationship of these effects to metacognitions about learning. Sentences which were elaborated in different ways were read to subjects by experimenters to establish levels of meaningfulness and identify effects on performance. Comprehension and confidence…

In a study conducted to examine potential of two-way television as an instructional medium, classroom observation data were collected from 32 presentations--two-way television and conventional--by seven medical faculty to medical students. Results reveal similar instructional strategies regardless of presentation mode, and mixed reaction by…

This field study examined learning effects attributable to instructional design characteristics when eighth-grade science students used a print encyclopedia or a videotex version of the encyclopedia to write term papers. Results suggest that specific effects of instructional design characteristics of a delivery system are of a limited nature. (MBR)

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…

Investigates and describes the current instructor experience of teaching college courses over the Web versus in face-to-face formats in terms of teaching strategies, social issues, and media effects. Discusses communication styles, relationship between students and instructors, instructor workload, and discussion patterns, and proposes a model…

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 instructor's methods compared with those intended by the instructional designer focuses on a study of undergraduate engineering students that was designed to investigate whether instructor delivery of the program as recommended regarding homework would yield higher student achievement. Treatments for the experimental and control…

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…

Describes study that was designed to compare student achievement scores from three different testing methods: paper-administered testing, computer-administered testing, and computerized adaptive testing. The California Assessment Program (CAP) item banks for grades three and six which this study incorporated are described, and results are…

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…
