In this study, learners worked with a simulation of harmonic oscillation. Two supportive measures were introduced: model progression and assignments. In model progression, the model underlying the simulation is not offered in its full complexity from the start, but variables are gradually introduced. Assignments are small exercises that help the…

As part of the research leading to the implementation of computer-based case simulations (CCS) for the licensing examinations of the National Board of Medical Examiners, gender differences in performance were studied for one form consisting of 18 cases. A secondary purpose of the study was to note differences in style or approach that might…

This brief paper is an anecdotal commentary on a class exercise developed for an advanced European History course covering the period 1815 to the present. It describes a role-play, case-study exercise designed to reinforce previously covered material. Students are directed to attend a mock peace conference to consider if any one country was…

In person-fit analysis, the object is to investigate whether an item score pattern is improbable given the item score patterns of the other persons in the group or given what is expected on the basis of a test model. In this study, several existing group-based statistics to detect such improbable score patterns were investigated, along with the…

The booklet is part of a grade 10-12 social studies series produced for bilingual education. The series consists of six major thematic modules, with four to five booklets in each. The interdisciplinary modules are based on major ideas and designed to help students understand some major human problems and make sound, responsive decisions to improve…

This pamphlet presents brief reviews of 38 population education software and online systems currently available. It includes mathematical models, simulations, databases, problem-solving games, online systems, and associations. The review includes a description of the program, the level at which it is aimed, required computer hardware, the vendor's…

This report describes and evaluates the K-12 driver and traffic safety education program at the Des Moines (Iowa) public schools. Four perspectives are evaluated: context, input, process, and product. The school district's mission, the program's philosophy, and the supervisor's viewpoint are outlined. The current program and its course content is…

This paper describes an item response theory (IRT) based method of differential item functioning (DIF) detection that involves neither separate calibration nor ability grouping. IRT is used to generate residual scores, scores free of the effects of person or group ability and item difficulty. Analysis of variance is then used to test the group…

A multidimensional item response theory (IRT) model for polytomously scored items, based on the graded response model and using the normal ogive, is developed; and an EM algorithm that may be used to estimate the parameters of the model is also discussed. The model is illustrated through a simulation study in which the polytomous item responses of…

The National Assessment of Educational Progress (NAEP) recently expanded its national survey to include state representative samples on a trial basis. In 1992, the NAEP undertook studied non-response in the trial assessment through two simulation projects. The first looked at state assessments that were similar to NAEP tests for states with low…

A business English course taught to adults in Ukraine is described, focusing on the classroom approach that incorporates imaginative continuous simulations and critical analysis tasks. It is noted that simulations ordinarily in business English courses have two shortcomings: they are disconnected episodes; and the situation, conditions, and…

A systematic study was conducted with a group of 10- to 12-year-olds using computer assisted instruction in a unit on fire which included a computer simulation of combustion. Three research questions were addressed to learn more about how the computer experience challenged the students' preconceptions: what the students thought the computer knew,…

This personal finance guide assists teachers and curriculum committees in the selection of appropriate materials. The listings follow a common format: title; a brief description of the materials; the areas covered; the cost of materials; and information on how to obtain them. Materials cover the following areas: financial planning; purchase of…

This paper establishes the roots of computers and automated teaching in the field of psychology and describes Dr. S. L. Pressey's presentation of the teaching machine; B. F. Skinner's teaching machine; Meyer's steps in composing a program for the automated teaching machine; IBM's beginning research on automated courses and the development of the…

This guide for using computers in the whole language classroom provides teachers with practical ideas for the use of computers to promote group interaction and cooperative learning, including: (1) software webs to assist theme development; (2) pre-computer activities to motivate students; (3) computer activities to develop software competence; (4)…
