Background: Rigorous meta-analysis holds promise to answer the ultimate important question in education: which interventions work and for whom? Evidence-based reform in education has contributed to a proliferation of well-designed experiments in recent years, which calls for updated systematic reviews. However, this proliferation is a double-edged…

As evidence-based reform becomes increasingly important in educational policy, it is becoming essential to understand how research design might contribute to reported effect sizes in experiments evaluating educational programs. The purpose of this study was to examine how methodological features such as types of publication, sample sizes, and…

Briefly describes the objectives and design of the MicroRead Index, a microcomputer-based index which utilizes word and sentence length to measure readability of written materials. The program computes a reading level and a consistency index for comparative analysis and determines whether the sample size used was adequate. (MBR)

Discusses two alternative metrics to detect computer software plagiarism: the Halstead metric drawn from the software science discipline and an ad hoc method drawn from program grading experience and identified by factor analysis. Possible explanations as to why the ad hoc method is more useful in identical-task environments are considered.…

Examines relationship between popular computer games and their players to discern how games motivate their players and general outcomes of popular computer game play in terms of substantive learning. The computer game environment, game economics and software, player characteristics, and how new and familiar games are played are described. (MBR)

Computer software that is intended to assist the qualitative researcher in the analysis of textual data is relatively new. One such program, the Data Collector, is a HyperCard computer program designed for use on the Macintosh computer. A tool for organizing and analyzing textual data obtained from observations, interviews, surveys, and other…

This paper discusses the incorporation of heuristics in computerized decision aids that are used for structuring decision problems. Decision theory is described in terms of linked subsystems, and sites where it is necessary to employ heuristic rather than normative, algorithmic procedures are identified. Production systems are then used to…

This paper describes a Prolog execution model which serves as the uniform basis of textbook material, video-based teaching material, and an advanced graphical user interface for Prolog programmers. The model, based upon an augmented AND/OR tree representation of Prolog programs, uses an enriched "status box" in place of the traditional…

This study used multiple regression analysis to relate computer user satisfaction to communication monitor (CM) variables. Results indicate the variables of user expectations, manufacturers, and vendors are most significant in affecting overall satisfaction, whereas number of systems represented and not using communication monitors have least…

Considers possibility of developing a computer tutor around an explicit concept-learning theory derived from machine learning techniques. Some problems with using the focusing (and similar) algorithms in this role are discussed and possible solutions are developed. Design for a guided discovery learning system for tutoring concepts is proposed.…

Reviews literature on conceptual conflict as facilitator of student learning and alternative conceptions, describes theories explaining occurence of alternative conceptions and conflict role in conceptual change, discusses a model of learning as conceptual change and its instructional implications, and presents results of studies which apply the…

Describes technique involved in designing a clinical simulation problem for the allied health field of respiratory therapy; discusses the structure, content, and scoring categories of the simulation; and provides a sample program which illustrates a programming technique in BASIC, including a program listing and a sample flowchart. (MBR)

This paper argues that research findings from the study of teaching could be very useful in enhancing knowledge and tools for the design of both conventional and intelligent instructional software. It also suggests that if the ways in which teachers effectively conduct instruction are different and in certain ways better than other media, and if…

This overview of computer uses in occupational training discusses three computer-based training modes--embedded, stand-alone, and adjunct training. An adjunct training system is described which captures task realism through a simulation to teach the use of a command and control system. A pilot study of this adjunct system's use is described.…

Describes two experiments which demonstrate improvement in reading speed as a result of an uncomplicated BASIC computer program which automatically assigns phrase structure to grammatical sentences to produce syntactically formatted text. Both experiments indicate poor readers are aided by this type of format. (MBR)
