The effects of some restraints not included in the classical assumptions of the F- and H-Test (e.g., correlation of mean and sample size) were examined in a simulation design. Also simulated was a situation in which two assumptions were not met simultaneously. (Author/BW)

Describes the use of two computer simulations in a journalism class to help teach information-gathering techniques and information evaluation. (HTH)

Computer generated data representative of 16 Auto Regressive Integrated Moving Averages (ARIMA) models were used to compare the results of interrupted time-series analysis using: (1) the known model identification, (2) an assumed (l,0,0) model, and (3) an assumed (3,0,0) model as an approximation to the General Transformation approach. (Author/BW)

Discusses how the power and potential of the computer may shape the classroom of the future by presenting a scenario of a classroom in the year 2001. The role of artificial intelligence in this environment is considered. (JN)

A computer simulation study was conducted to investigate the amount of uncertainty added to National Assessment of Educational Progress estimates by equating error under three different equating methods and while varying a number of factors that might affect accuracy of equating. Data from past NAEP administrations were used to guide the…

This study sought to answer the question, Do all students benefit equally from the use of a hypermedia Goal-Based Scenario (GBS)? GBS is a subcategory of anchored instruction. The correlation between the demographic variables and achievement and specific cognitive variables and achievement was explored using a lesson on DNA, and was tested on…

Situation awareness is defined as an evaluative product based on expert performance criteria. This article examines the importance of training simulation systems in developing situation awareness, focusing on high fidelity procedural training, expert knowledge and experience, and attitude and emotional state. Discusses other related issues. (68…

Examines the effects of power structures in negotiations using a simulation of the historic Lausanne Peace Talks. Compares the two power configurations represented in the talks to a third bilateral configuration. Discusses the impact of the manipulated conditions on perceptions and outcome measures, aspects of the negotiating process, perceptions…

Discusses how students learn to model in scientific contexts. Highlights include current research in science education; a computer-based simulation of a student learning to model; an example of a physics task; collaboration with another student; a dialog mechanism; and external representations. (LRW)

Describes the implementation of an intelligent tutoring system that employs a game environment and object-oriented user interface for teaching and learning, based on a computer game developed for industrial training. Discusses adventure games, game environments in education, simulation support, and user interface design. (Author/LRW)

Studied the relationships between two real time dynamic decision making tasks (microworlds) and one intelligence test with 100 Swedish adults. Raven's Progressive Matrices scores were a predictor of success in the two microworlds. Discusses methodological problems with microworlds. (SLD)

Considers online Internet chatting as a means to resolve simulation tasks in lieu of face-to-face negotiation and suggests that online chatting extends linguistic opportunities for participation in small-group settings while retaining the interactive qualities of spoken conversation. Concludes that language learners who are normally reluctant to…

The equating of results from the PC-BILOG computer program to an underlying metric was studied through simulation when a two-parameter item response theory model was used. Results are discussed in terms of the identification problem and implications for test equating. (SLD)

A large class that must share one computer can still get the benefits of adventure/simulation software if students work in small groups. Teamwork stimulates sharing and cooperation. The importance of planning, useful peripherals, follow-up activities, and product information are included in this article. (IAH)

Parameter recovery in the graded-response model was investigated using the MULTILOG computer program under default conditions. Results from 36 simulated data sets suggest that at least 500 examinees are needed to achieve adequate calibration under the graded model. Sample size had little influence on the true ability parameter's recovery. (SLD)
