According to a recent survey, the quality of educational software is the single most stated concern of computer educators in Canada. Only a small fraction of the educational software is evaluated. The evaluation approaches that have emerged to deal with this problem are subjective and unreliable, and they do not provide an overall impression of a…

In keeping with current Department of Defense policies on integrated diagnostics and a reduced reliance on paper-based documentation, the concept of a portable, expert-system-based job aid and training device was proposed to assist inexperienced electronics maintenance technicians in learning to maintain sophisticated equipment. A prototype was…

The first goal of this research project was to demonstrate the use of computer assisted video instruction (CAVI) for teaching mildly handicapped students school to community transition skills. Two CAVI learning modules were developed on asking for help and budgeting. The first includes eight lessons focusing on questions of why, when, who, what,…

The purpose of this teaching unit is to approach elementary probability problems in three ways. First, actual trials are performed and results are recorded. Second, a simple computer simulation of the problem provided on diskette and written for Apple IIe and IIc computers, is run several times. Finally, the mathematical solution of the problem is…

This report describes the Intelligent Maintenance Training System (IMTS), a set of software tools for composing and delivering simulation-based technical training. The goal in developing IMTS was to generate instructional interactions from device models composed of instances of generic objects. Problem selection in IMTS relies on the use of a…

The use of new extension of standard Item Response Theory (IRT) modeling of dichotomous items to include external variables is proposed. External variables may appear both as categorical grouping variables and as continuous variables; this requires the formulation of a model for the relationships between the external variables and the response…

These three volumes list and describe a total of 65 new educational software products. The lists are the result of February and September 1988 polls of 10 computer coordinators from large educational software preview centers and evaluation agencies, who were asked to identify new products they had seen which, in their professional opinion, were…

An integral part of the curriculum in introductory biology courses is the study of Mendelian genetics. Results from genetics learning studies and needs assessments demonstrated the need for additional intensive research in biology education and genetics learning. There exists a lack of detailed information describing reasoning patterns and…

The expert system computer simulation detailed in this report is designed to investigate patterns of valuing in decision-making about dossiers of performance data used in teacher promotion evaluations. The knowledge base for the simulation consists of 111 questions organized into 117 rules. The questions and linked advice were derived from…

In order to evaluate our methods and approaches of estimating the operating characteristics of discrete item responses, it is necessary to try other comparable methods on similar sets of data. LOGIST 5 was taken up for this reason, and was tried upon the hypothetical test items, which follow the normal ogive model and were used frequently in…

Designed to provide teacher-trainees with practice before entering a real classroom, a microcomputer-based simulation of classroom interaction became a key component in the curriculum of two introductory methods courses offered at the University of Virginia. Twenty-two participants used IBM-PC equipment to complete two skill modules. Each module…

The effects of varying degrees of correlation between abilities and of various correlation configurations between item parameters on ability and item parameter estimation using the three parameter logistic model were examined. Ten two-trait configurations and one unidimensional test configuration for 30 item tests were simulated. Each…

This paper describes DATASIM, a comprehensive software package which generates simulated data for actual or hypothetical research designs. DATASIM is primarily intended for use in statistics and research methods courses, where it is used to generate "individualized" datasets for students to analyze, and later to correct their answers.…

The essays in this volume explore the ways the Speech Communication Association (SCA) might use the computing technology of the microprocessor. The six chapters focus on the following topics: (1) ways the new technology will impact on the processing of manuscripts for speech journals and the SCA's national conventions, with particular emphasis on…

Responses to a sample test were simulated for examinees under free-response and multiple-choice formats. Test score sets were correlated with randomly generated sets of unit-normal measures. The extent of superiority of free response tests was sufficiently small so that other considerations might justifiably dictate format choice. (Author/DWH)
