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…

Some of the problems that occur for researchers using the TICCIT computer assisted instructional system are described. The underlying learning strategy of the TICCIT system states that the student rather than the developer is best able to select the order of instructional frames. In order to successfully engage in research with the TICCIT system,…

Since about 1962, researchers have explored the effectiveness of educational software in the schools under various conditions, and many have concluded that computer assisted instruction (CAI) is effective. Many of the studies reviewed to support this conclusion, however, had design flaws. Reviews of educational software effectiveness studies have…

Reviews research conducted to determine if learning to program in Logo has a positive effect on other aspects of thinking, based on Seymour Papert's findings on Logo. The appropriateness of research on Logo and programming is discussed, and research studies involving elementary and secondary school children are briefly described. (LRW)

Proposes directions to help researchers balance instructional technology goals with the performance of well-designed and scientifically sound studies. Issues concerning the external validity of studies, use of media replications, and learner control as a means of adapting instructional strategies to individuals are emphasized, and designs for…

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…

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…

To control for interactions in learning research due to subjects' prior knowledge of the instructional material presented, an imaginary curriculum was presented with a computer assisted technique based on Carl Berieter's imaginary science of Xenograde systems. The curriculum consisted of a classification system for ten conceptual classes of…

The suspected sources of confounding in current meta-analytic studies of computer based instruction (CBI) are uncontrolled effects of instructional method and/or the John Henry Effect (i.e., compensatory rivalry). To determine which confounding is most plausible, a random 30% sample of the 128 studies which formed the original Kulik meta-analyses…

Provides an overview of research on the effectiveness of microcomputer applications with at-risk students and suggests that many findings in the literature are questionable because of flaws in research methodology. Issues relating to measurement, learning environment, computer utilization, gender, and socioeconomic status are addressed, and…

The second of four symposium papers brings together the results of four separate statistical analyses of findings on computer-based instruction (CBI) in 199 comparative studies, of which 32 were conducted in elementary schools, 42 in high schools, 101 in universities and colleges, and 24 in adult education settings. Each was a controlled,…

Eight articles review and report on research involving computers and problem solving skills. Topics discussed include research design; problem solving skills and programing languages, including BASIC and LOGO; computer anxiety; diagnostic programs for arithmetic problems; and relationships between ability and problem solving scores and between…

A study was conducted to determine the relative effectiveness of the traditional and infused (computer-assisted instruction or CAI) approach to basic skills instruction for students in a vocational education program. The sample for the study consisted of 41 male students in the air conditioning/refrigeration program at the Houston Community…
