Graphical plans for construction of machinery and architecture have evolved over the last 6,000 years beginning from hieroglyphics to drawings on printable media, from the "Golden Age" of engineering graphics to the innovation of computer graphics and prototyping. The evolution of engineering design graphics as a profession has also evolved. Years…

This is the final evaluation report of the On Growth and Form (OGAF): Learning Concepts of Probability and Fractals by Doing Science project that aimed at engaging high school students in hands-on science activities, experiments, and computer simulations that use probability and fractal geometry to model ragged structures in the real world.…

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 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…

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 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 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)…

Credentialing agencies that use multi-test examinations (MTEs) should be concerned with the quality of pass/fail outcomes as well as with the proportion of candidates passing. This study addressed three questions: (1) the effects on passing rate of MTE reliability, number of tests comprising a MTE, and correlations between pairs of component…

A study of 228 undergraduate psychology students examined the effectiveness of a prototype of "heatlab," a laboratory simulation written in PCE-PROLOG, intended for remedying misconceptions of the concepts "heat" and "temperature." The effect of varying the amount of structure on students' understanding and the…

Instructional television (ITV) is an effective medium for improving teaching and learning at all levels of education. Thirteen brief case studies provide teacher's insights into how ITV can be integrated with newer computer and satellite technologies to provide instructional opportunities in numerous academic subjects for all students. The voices…

This presentation provides an in-process review of researching efforts at the U.S. Army Research Institute and the Institute for Defense Analysis to update their earlier studies of Computer Based Instruction (CBI) cost-effectiveness. In the presentation five topics are addressed: (1) the differences between education and training, and why they…

This report describes the first of three stages in a study in the domain of problem solving: the definition and explication of schema knowledge. One objective of this research is to understand how schema knowledge is acquired and used in the chosen domain. The focus is on ways in which instruction influences the development of specific knowledge…
