This longitudinal study serves as a model for examining and understanding the role of editing and its contributing factors in writing center tutorials. The study quantifies the frequency of and time devoted to editing in over 4,000 writing center tutorials and finds these quantities differ in statistically significant ways when broken down by user…

The developmental sequence of mathematics courses in most 2-year and 4-year colleges is designed to prepare students to succeed in college-level math courses. That is, students must complete this sequence in order to progress to courses such as statistics, college algebra, precalculus, calculus, and differential equations. Research on the…

Describes two classroom experiments that investigated the effects of using projected-display computers: the first compared teaching a course using a projected display with teaching the course in a computer lab; and the second compared using a computer and projected display with standard lectures. Effects on test scores are discussed. (three…

Reports on ways in which interactive video-based courseware is being used with students studying for vocational qualifications at Thames Valley University (United Kingdom). Two alternative models using interactive video are described, one using multiple workstations and one using a single workstation led by a tutor. (Contains six references.) (LRW)

Describes a CD-ROM version of a basic course in exercise physiology that was developed in the United Kingdom to overcome problems of staff time, expense, ethical considerations, and large student numbers. Compares it to a traditional course and concludes that adding more active learning approaches to the CD-ROM would enhance student learning. (LRW)

Discusses the use of computers in college classrooms as presentation systems, as structured laboratories, to modify traditional lectures, and for self-paced instruction. Classroom dynamics are discussed, needed curricular modifications are considered, appropriate evaluation techniques are suggested, and problems are examined, including a lack of…

Describes a study conducted by the U.S. Navy that compared training effectiveness and user acceptance of live instruction and six different alternative instructional television (ITV) technologies that had differing levels of audio and video communication. The ITV laboratory configuration is explained, and instructor preferences and skills are…

This article is a review of the impact upon science learning of classroom and laboratory uses of computers in grades K-16 as revealed by published, peer-reviewed research from 1988-95. Highlights include problems with media-comparison studies, computer-assisted instruction, computer simulations, microcomputer-based laboratories, interactive video,…

Describes a study that explored the impact of using interactive video in a seventh grade earth sciences curriculum. The effectiveness of interactive video and traditional text instructional methods in different settings (computer lab versus classroom) are compared, gender differences are examined, and recommendations for future research are given.…

Describes a study of high school students that investigated the impact of computer-assisted learning (CAL) integrated with classroom-laboratory instruction versus classroom-laboratory work alone on students' achievement and mastery of science process skills in a microbiology course. Posttest scores are compared and the curriculum integration of…

Describes the use of a HyperCard-based computer-assisted instructional program at Otago Polytechnic (New Zealand) that replaces traditional lectures in analytical chemistry. Topics discussed include the instructor's role; computer-managed testing; writing the computer program; computer simulations; digitized video movies; and student reactions.…
