Describes a case study of secondary schools in Ibadan (Nigeria) that was conducted to determine whether programed instruction was more effective than traditional classroom methods in teaching chemistry. Treatment of control and experimental groups is described, gender differences are examined, and implications for educational practice and further…

Describes a study of secondary school students in the Netherlands that compared the use of paper and pencil or computer spreadsheets to solve correlational problems in geography. Discusses results of videotape transcripts that compared teacher and student behaviors and considered mechanisms through which computers contribute to learning.…

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…

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…

Discusses results of a study of high school students that was conducted to determine, through measures of student achievement, the educational effectiveness of interactive satellite delivery compared with traditional classroom instruction in anatomy and physiology and to compare the attitudes toward anatomy and physiology of distance students and…

A study examined the use of Telidon, the Canadian videotex system, as a delivery vehicle for computer-based distance education in an introductory high school mechanics course. Specifically analyzed were (1) the relative educational effectiveness of Telidon, traditional correspondence, and traditional, in-school modes of instruction; (2) the…

Discussion of teaching complex knowledge domains through exploration highlights two experiments that investigated the educational value of a Dutch computer simulation program which models the relationship between erosion and agriculture in a developing country as part of the secondary school geography curriculum. Learning by doing versus learning…

Describes study that compared the attainment gains of Guyanan secondary school children in science and geography following two different learning regimes, i.e., systematically designed learning materials, and conventional teaching. Implications of the results for curriculum design and teacher training are discussed. (Author/LRW)
