One of the great strengths of Jim Kaput's research program was his relentless drive towards scaling up his innovative approach to teaching the mathematics of change and variation. The SimCalc mission, "democratizing access to the mathematics of change," was enacted by deliberate efforts to reach an increasing number of teachers and students each…

Present research connected with computer-based instruction indicates that many investigators rely on conventional experimental design and data analysis to address the research question. Although this is appropriate in many cases, the limits of hard and software resources and sample size in other cases have made conventional approaches a poor…

This paper presents five designs (three one-group and two two-group) which can be effectively employed to study computer-based methods in non-laboratory settings, including actual classroom implementation, where a non-treatment control design may not be feasible. These designs are sequential analysis, value-added analysis, non-equivalent dependent…

Computer-assisted observer training of 12 college students using interactive videotapes produced observational repertoires that accurately reflected a wide range of targeted events. Maintenance (thinning feedback) and nonmaintenance (no feedback) training generated equivalent degrees of observational accuracy. Data indicated the standard practice…

Presents five research designs--sequential analysis, value added analysis, nonequivalent dependent variables, regression discontinuity, cohort design--for studying computer-based teaching methods when a randomized two-group design is impractical; provides examples of studies employing these designs and decision flowchart; and discusses selection…

The Apple Classroom of Tomorrow (ACOT) project is an attempt to alter the instructional premises of a selected group of seven experimental classrooms in the United States by saturating them with computer technology. A recent proposal submitted to Apple Computer described STAR (Sensible Technology Assessment/Research), which includes both…

Along with cost, and hence availability of hardware and quality educational courseware, the major barrier to full implementation of microcomputers is the lack of knowledge possessed by researchers and educational practitioners alike regarding the nature of the knowledge, skills, and attitudes a teacher must have to successfully use microcomputers…

Separate meta-analyses have been completed recently on the effectiveness of computer-based education (CBE) in elementary schools, high schools, colleges, and nontraditional postsecondary institutions. Several conclusions can be drawn from these meta-analyses. First, although CBA has not been uniformly successful in all its guises and at all…

Reviews, analyzes, and critically assesses a sample of articles reporting research findings related to the instructional effectiveness of computer-assisted instruction (CAI). Problems in CAI research are described, including validity of the experimental research design, and current trends in CAI research are discussed. (31 references) (LRW)

Addresses the implicit assumption that instructional media represent meaningful experimental variables independent of instructional content or strategy. Results of computer-based instruction (CBI) studies (both well-designed and flawed) and meta-analyses are reviewed to support the authors' position that this assumption is invalid, and new…

Critiques comparative research and evaluation methods used to assess effectiveness of interactive video and proposes alternative models of research design that go beyond comparative analysis into understanding and control of the effective dimensions of interactive video, i.e., controlled correlation; instructional events, cognitive psychology, and…

Presents an overview of computer assisted instruction (CAI) as an instructional technique; describes studies on CAI effectiveness in compensatory education; discusses elements that need to be addressed to create a positive relationship between CAI, compensatory education, and achievement gains; and reviews evaluation designs appropriate in…

Describes a feasibility study designed to investigate interactive video and the balance of student versus program control with respect to the sequence of content presentation, the choice of how many practice exercises to do, and the strategy for alternating between the modes of receptive and active learning.

This examination of the research on computer-based instruction for the major academic subjects in the elementary and secondary grades considers three varieties of empirical data--surveys of computer-using teachers, school district program evaluations, and experimental field studies. A discussion of the findings of two national surveys of…

This study investigated the degree to which seventh- and eighth-grade students of different abilities acquired strategic planning knowledge from a problem-solving computer game called Wumpus. Regression analysis was used to determine the influences of individual differences and either activating or modeling instruction, and to assess transfer of…
