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)

Simulation studies were used to explore the relationship between Type I error rates (statistical conclusion validity) and multiple testing in data sets exhibiting varying degrees of independence. Implications for reporting and interpreting educational data are discussed, and methods of determining or reducing Type I error incidence are presented.…

The distinction between deterministic and statistical reasoning in the application of models to educational measurement is explicated. Issues addressed include the relationship between data and estimation equations, distinction between parameters and parameter estimates, and power of tests of fit of responses across the ability continuum. (TJH)

It is demonstrated, theoretically and empirically, that item sets can be selected that meet the unidimensionality assumption of most item response theory models, even though they require more than one ability for a correct response. A method for identifying such item sets for test development purposes is presented. (SLD)
