This paper reviews the basic elements of the EM approach to estimating item parameters and illustrates its use with one simulated and one real data set. In order to illustrate the use of the BILOG computer program, runs for 1-, 2-, and 3-parameter models are presented for the two sets of data. First is a set of responses from 1,000 persons to five…

In April of 1982, the German Federal Armed Forces initiated the first empirical pilot project in the area of computerized adaptive testing (CAT). The configuration of hardware, psychological section, and physiological section is discussed, as well as two current problems (data transfer from the TEST 2000 microcomputer to a large sized computer for…

This report is a collection of 11 recent papers by the Human-Machine Interaction Group at the University of California, San Diego. The following papers are included: (1) "Stages and Levels in Human-Machine Interaction," Donald A. Norman; (2) "The Nature of Expertise in UNIX," Stephen W. Draper; (3) "Users in the Real…

Three research efforts that used computer-based simulations for maintenance training were in progress when this report was written: Game-Based Learning, which investigated the use of computer-based games to train electronics diagnostic skills; Human Performance in Fault Diagnosis Tasks, which evaluated the use of context-free tasks to train…

The focus of this study is on the estimation procedures implemented in BILOG, a computer program. One purpose is to compare the item parameter estimates produced by various procedures available in BILOG. Four different models are used: the one, two, and three parameter model and a three parameter model with common guessing parameters. The results…

The focus of this workshop involving people from 13 countries in Asia and the Pacific Region was on using computers to assist learning in mathematics. The report contains the following sections: (1) Introduction; (2) The Mathematics Curriculum: Innovation and Change; (3) The Mathematics Classroom: New Ideas with Computers; (4) Software: Quality…

Different formats for four types of research items were studied for ease of computer data entry. The types were: (1) numeric response items; (2) individual multiple choice items; (3) multiple choice items with the same response items; and (4) card column indicator placement. Each of the 13 experienced staff members of a major university's Data…

Discussed are technological advances applying computer techniques for image acquisition and processing, including digital radiography, computed tomography, and nuclear magnetic resonance imaging. Several diagrams and pictures showing the use of each technique are presented. (YP)

Discussed is a radionuclide imaging technique, including the gamma camera, image analysis computer, radiopharmaceuticals, and positron emission tomography. Several pictures showing the use of this technique are presented. (YP)

Described are applications of computers in the field of medicine, including patient monitoring, patient treatment, patient imaging, patient therapy, and rehabilitation. (YP)

The experience of Coastal Carolina College (South Carolina) suggests that, although the small college often has the same academic reporting demands for intercollegiate athletics as a large institution, the nature of the institution creates different recordkeeping and reporting challenges. Computerization and active institutional research staff…

This paper examines effects of combining long-range planning and computer-based modeling in institutions of higher education, with examples from application at Butler University (Indiana). The model was developed due to a need to obtain a 5-year forecast of revenues and expenditures and consists of eight dynamic submodels--one for each of the five…

The instructional effectiveness of using an IBM personal computer with an Electrohome Character projector and a flat screen to display instructional material was analyzed with 89 students enrolled in a course on management information systems at McGill University. The lesson used was an introduction to VisiCalc, an applications software package,…

These papers from the fifth annual meeting of the Canadian Mathematics Education Study Group are organized similarly to the meeting, presenting materials from the lectures, working groups, special groups, and panel groups, as well as ad hoc groups. Iverson delivered one lecture on computer programming, stressing the place of APL, while Kilpatrick…

This paper reports on the effects of structuring problem solving activities of novices in the domain of physics in a way consistent with the problem solving approaches used by experts. A total of 42 undergraduate students who completed a first semester physics course and received a grade of B or better participated in this study. The treatment…
