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)

The study developed and evaluated computer simulations for teaching apparel merchandising concepts. Evaluation results indicated that teaching method (computer simulation versus case study) does not significantly affect cognitive learning. Student attitudes varied, however, according to topic (profitable merchandising analysis versus retailing…

Describes a computer simulation called "Supercontinent Aggregation and Dispersal" designed to model the interplay between the movement of the continents and the flow patterns of rock in the mantle. Discusses the strengths and weaknesses of the program in relation to the effects of continents on the mantle. (CW)

Description of microcomputer-based simulations used to help teachers-in-training acquire basic teaching and classroom intervention skills highlights the Speech Synthesizing Simulation, which is designed to train speech language clinicians. Computer-generated verbal exchanges between a teacher and a class of computer-defined pupils during a…

Simulations provide practice in aspects of care without harm or inconvenience to the actual patient. Five types of simulations have been identified that vary in their fidelity to real situations - written simulations, three-dimensional models, computer-based patient management problems, multi-media approaches and simulated patients. Uses and…

Evaluates MUSICSHAPES, a graphic music construction software program which manipulates sound in terms of pitch, rhythm, timbre, and sequence to help students create complex synthesizer compositions. Intended for ages eight to adult, the program utilizes Apple II computers and additional hardware. Discusses how MUSICSHAPES can be used effectively…

Eighteen undergraduates participated in two consecutive microcomputer simulation sessions, receiving specific information about classroom management between sessions. Among results were a significant increase in mean number of appropriate management responses made to computer-generated student talkouts and a significant decrease in amount of time…
