This paper describes the effects of the implementation of constructivist techniques with interactive computer simulations on conceptual understanding of plant nutrition and critical thinking skills in heterogeneously grouped secondary biology classrooms. The study focused on three strategies for teaching plant nutrition: (1) traditional; (2)…

The purpose of this report is to communicate findings on current knowledge of simulation design, development, and evaluation. Research on this project was guided by questions posed by the Defense Systems Management College in Fort Belvoir, Virginia. These questions fall into three categories: the constituents of good instructional simulations, the…

A Monte Carlo study was conducted to compare the performance of three statistical indices of test item bias in small samples of examinees. The statistical indices compared were the Delta method, the Mantel-Haenszel (MH) method, and the Standardization method. Sample sizes of 50, 100, and 200 were examined. One thousand samples of each size were…

This study examined performance of a simulated computerized adaptive test that was designed to help direct the development of a medical recertification examination. The item pool consisted of 229 single-best-answer items from a random sample of 3,000 examinees, calibrated using the two-parameter logistic model. Examinees' responses were known. For…

In order to build robust natural language processing systems that can detect and recover from miscommunication, the investigation of how people communicate and how they recover from problems in communication described in this artificial intelligence report focused on reference problems which a listener may have in determining what or whom a…

An overview of the current status of the videodisc industry and observations on future directions for videodisc technology are presented in this paper. Information was drawn from interviews with presenters at the 1984 Nebraska Videodisc Symposium and the February 1985 Society for Applied Technology Conference, discussions with hardware…

The paper discusses a number of issues concerning the practical usefulness of cognitive psychology research, and presents a case study of pilot training methods to illustrate a model of research processes that produces outcomes which contribute to both basic and applied research goals. Research studies are described as varying in the degree to…

Describes three studies which explored the use of computer assisted instruction with mildly handicapped secondary school students. Comparisons with non-handicapped students are made in vocabulary development, using drill and practice; concept instruction in elementary logic, using a tutorial approach; and problem solving in health education, using…

The purpose of this study was to use realistically simulated data to evaluate various CAT designs for use with the verbal reasoning measure of the Medical College Admissions Test (MCAT). Factors such as item pool depth, content constraints, and item formats often cause repeated adaptive administrations of an item at ability levels that are not…

This study looked at the effect of contextual advisement and competition on transfer of mathematics skills in a computer-based instructional simulation game and simulation in which game participants helped their "aunt and uncle" fix up a house. Competition referred to whether or not the participant was playing against a computer…

Presents an alternative model for using the computer as an aid in teaching mathematics. Highlights include a mathematics teaching model; computer software for drill and practice, tutorials, simulation, games, and computer managed instruction; integrating computers into the mathematics curriculum; and examples of computer activities for…

Describes a study that examined the effects of an interactive video computer-aided simulation program on instructing preservice education majors in classroom management issues. Topics include student achievement, class rank, stages of concern, computer anxiety, learning modality, the Classroom Management Achievement Test, and student reactions.…

Describes a self-administered microcomputer-based simulation that allows teacher educators to create customized simulated classroom experiences for their students. Lesson performance measures are discussed, postlesson feedback variables are described, self-perception measures are explained, and results of a posttraining evaluation of the…

System-initiated adaptive advice and learner-requested nonadaptive background information were investigated in computer simulation game experiments with 64 seventh graders, 38 college students, and 80 seventh and eighth graders in Germany. Results are discussed in terms of theories of problem solving, intelligence, memory, and information…

This article describes the results of a survey of 93 final-year degree students concerning their views toward using Thavikulwat's DEAL: A Business Gaming Simulation. The focus is on students' perception of the usefulness of using computer simulation as a learning tool in a strategic management course. Certain comparison was made with other similar…
