Investigates the impact of computer simulation on students' academic achievement and their mastery of science process skills with regard to their cognitive stages. Based on the computer simulation program "The Growth Curve of Microorganisms" which requires 10th grade biology students to use problem solving skills while simultaneously…

Describes a study that examined the effects of goal setting on undergraduate students competing in a computerized business simulation. Group cohesiveness is discussed, treatments for the experimental and control groups are described, perceived team success is measured, and team simulation performance is evaluated. (30 references) (LRW)

Reviews the research literature on the use of computer-assisted instruction (CAI) in the education of health professionals. The use of tutorial software, computer simulation, and interactive multimedia are discussed; the fields of nursing, medical, pharmaceutical, and allied health occupations education are covered; and further research needs are…

Describes an activity to solve an applied problem using a random-number-based simulation. Provides objectives, prerequisites, directions, extensions, answers, a computer program, and worksheets for the activity. Six references are listed. (YP)

Describes simulation software that was used with an LCD overhead display and laptop computers for large introductory psychology courses. The use of experiment simulators to increase student interest and activity is discussed, hardware is explained, and interaction between students, instructor, and the simulation is described. (14 references) (LRW)

Three correlation matrices (PEARSON, POLYCHORIC, and TOBIT) were used to obtain reliability estimates on ordered polytomous variable models. A Monte Carlo study with different levels of variable asymmetry and 400 sample correlation matrices demonstrated that the PEARSON matrix did not perform as well as did the other 2 matrices. (SLD)

Compares retention of popular science material by fifth grade students using either computer simulation software or expository text as the instructional tool. Finds a statistically significant superiority in favor of the expository text group. (RS)

Describes projects developed through the Long Distance Learning Network (LDLN) that experimented with using telecommunications in classrooms in the United States and in other countries. A creative writing project involving elementary school students in the United States, Canada, and Australia is described, and a seventh-grade geography project is…

Discusses the use of the mathematics classroom for discovering the relationship among computers, mathematics, and real-world problems. Provides three probability problems and compares the results of three methods, actual trial, computer simulation, and mathematical solution. (YP)

A probabilistic item response theory (IRT) model is developed for pair-comparison design in which the unfolding principle governing the choice process uses a discriminant process analogous to Thurstone's Law of Comparative Judgment. A simulation study demonstrates the feasibility of estimation, and two examples illustrate the implications for…

Shows that graphs can reveal much about feedback systems that formula conceal, especially as microcomputers can provide complex graphs presented as animations and allow students to interact easily with them. Describes feedback systems, evolution of the system, and phase diagram. (YP)

Explains a computer simulation on post-revolutionary Russia in which students must make decisions in order to retain power and improve the economy. Decision areas include improving agricultural productivity, increasing industrial productivity, and establishing the production of consumer goods. (LS)

A procedure--based on item response theory--for testing the hypothesis of unidimensionality of the latent space is proposed. Use of the procedure is supported by an asymptotic theory and a Monte Carlo simulation study. The procedure tests for unidimensionality in test construction and/or compares two tests. (SLD)

Illustrates some of the practical issues and problems connected with the design and use of computerized business games by describing three games which have been developed and operated by staff at Leeds Polytechnic Department of Business Management (United Kingdom). Sample input and output forms are included. (nine references) (LRW)

Presents model of instructional strategy planning that links specific cognitive learning and thinking processes with specific computer-based instructional strategies. Topics discussed include memory systems; types of knowledge; drill and practice; tutorials; task-oriented simulations; problem-oriented simulations; and self directed experiences.…
