General guidelines are developed to assist practitioners in devising operational computerized adaptive testing systems based on the graded response model. The effects of the following major variables were examined: item pool size; stepsize used along the trait continuum until maximum likelihood estimation could be calculated; and stopping rule…

Discusses the extent to which computers can understand natural language. Considers assertions that computers can be described as literate, and considers more generally the purpose of designing machines which perform like humans. (RS)

Explores a method of combining convention and intention by representing conversation structure with conversation MOPs (schematic structures that store conversation rules as generalized episodes associated with goals the episodes achieved). Discusses how conversation MOPs process the opening portion of a dialogue in an interactive advice-giving…

Investigates the growing popularity of computerized economic modeling as a computer-assisted instructional aid and the associated educational benefits. Provides an overview of current modeling, simulation, and econometrics programs and attempts to identify trends in computer-assisted instruction in economics. (Author/GEA)

The purpose of this study was to determine differences in learning outcomes of students taught computer applications through supervised laboratory instruction versus video simulation. No differences were observed for time required to complete an application, proper use of commands, or retention of the learned application. (Author)

Describes the application of case analysis to a learner-centered microcomputer-based instructional model. Topics discussed include the use of computer-based case analysis with adult students; case planning; and two sample cases, one a decision-making model and one a technical model. (21 references) (LRW)

Provides commentaries on professional and personal experiences in the development of simulations in the study of international affairs. Describes the evolution in Simulated International Processes projects from a person-machine format to an all-computer simulation. Discusses work with the military, field work, teaching experiences, difficulties,…

This simulation investigated two procedures that reduce differences between paper-and-pencil testing and computerized adaptive testing (CAT) by making CAT content sensitive. Results indicate that the price in terms of additional test items of using constrained CAT for content balancing is much smaller than that of using testlets. (SLD)

The interact simulation environment has the potential to overcome problems associated with simulations by improving the lack of cost effectiveness, providing online guidance to students, and tailoring the supporting material to suit a wide range of contexts. Results show a flexible teaching and learning environment allows for teacher creativity.…

Describes the architecture of a distributed, networked, multimedia learning environment for macroeconomics, which employs gaming and simulation methods. Details include a conceptualization of the system and discussion of its function and structure. (JKP)

Includes four articles: "Virtual Reality" (Kopf), description of its uses in computer-assisted design, architecture, and technical training; "SME (Society of Manufacturing Engineers) Robotics Contest Opens Doors to Future" (Wagner); "Superconductivity" (Canady), description of classroom demonstrations and experiments;…

Describes a linguistic analysis computational system that responds to highly complex queries about morphosyntactic and semantic structures contained in large sets of language acquisition data by identifying, displaying, and analyzing sentences that meet the defined linguistic criteria. (30 references) (Author/CB)

Smallest exact confidence intervals for the ability parameter of the Rasch model are derived and compared to the traditional asymptotically valid intervals based on Fisher information. Tables of exact confidence intervals, termed Clopper-Pearson intervals, can be drawn up with a computer program developed by K. Klauer. (SLD)

Six computer applications in education are word processing, computer-assisted instruction, computer-aided design, computer authoring systems, computer data systems, and computer storage. Computers may assist students with three learning stages: acquisition, transformation, and evaluation of information. Advances in computer programing, software,…

Using a Monte Carlo simulation, a bootstrap procedure was evaluated for setting a confidence interval on the unrestricted population correlation (rho) assuming various degrees of incomplete truncation on the predictor. Sample size was the most important factor in determining accuracy and stability. Sample size should be at least 50. (SLD)
