A variety of paired comparison, triple comparison, and ranking experiments are discussed as generalized linear models. All such models can be easily fit by maximum likelihood using the GLIM computer package. Examples are presented for a variety of cases using GLIM. (SLD)

Reviews the literature dealing with the role of computers in psychiatric interviewing, and with the role of the computer as a patient or as a therapist. Efforts to develop forms of computer-assisted therapy are described, and implications for the mental health field are suggested. (40 references) (LRW)

Results of a Monte Carlo study with 4 populations (3,072 conditions) indicate that when distributions depart markedly from normality, nonparametric analysis and parametric analysis of transformed data show superior power to parametric analysis of raw data. Under conditions studied, parametric analysis of transformed data is more powerful than…

Discusses model-based simulation for training, explains an object-oriented approach, and describes RAPIDS, an authoring system for the production of interactive graphical models and instruction based on those models. Highlights include intelligent tutoring systems; transaction shells; tools for authoring models; and a course on retinal information…

Coefficient alpha was examined through computer simulation as an estimate of test reliability under violation of two assumptions. Coefficient alpha underestimated reliability under violation of the assumption of essential tau-equivalence of subtest scores and overestimated it under violation of the assumption of uncorrelated subtest error scores.…

Gives an overview of the development of multimedia, from the combination of film and computer graphics used during the 1960s to present day jet aircraft simulators. Definitions of multimedia, virtual reality, the use of compact disks to deliver digitally recorded information, and the economic need for the technology are discussed. (KRN)

Effects of overextracting factors and components within and between maximum likelihood factor analysis and principal components analysis were examined through computer simulation of a range of factor and component patterns. Results demonstrate similarity of component and factor scores during overextraction. Overall, results indicate that…

Whether it is possible to develop a classification function that identifies the underlying range restriction from sample information alone was investigated in a simulation. Results indicate that such a function is possible. The procedure was found to be relatively accurate, robust, and powerful. (SLD)

Discusses instructional gaming and examines the impact of Thomas Malone's theory of intrinsically motivating instruction. Relevant literature is reviewed to establish common threads, and implications of the gaming literature for future study of gaming and instructional design are suggested. (Contains 25 references.)

A numerical approach for computing standard errors (SEs) of a linear equating is described in which first partial derivatives of equating functions needed to compute SEs are derived numerically. Numerical and analytical approaches are compared using the Tucker equating method. SEs derived numerically are found indistinguishable from SEs derived…

A Fisher's Z transformation is developed for the corrected correlation for conditions when the criterion data are missing because of selection on the predictor and when the criterion was missing at random, not because of selection. The two Z transformations were evaluated in a computer simulation and found accurate. (SLD)

A computer simulation compared significance tests of correlation coefficients calculated from initial scores, from ranks assigned by the Spearman method, and from three kinds of modified ranks. Implications of findings for the idea that rank correlation is a nonparametric correlation method are discussed. (SLD)

Similarities in content, methods, sequence, and social context between adult education and cognitive apprenticeship make the latter an appropriate approach for a computer-assisted learning program for adults. (SK)

Based on a spiral model of technology evolution, elementary students used LOGO computer software to become both developers and users of technology. The computerized environment enabled 87% to reach intuitive understanding of physical concepts; 24% expressed more formal scientific understanding. (SK)

Describes the results of an effectiveness evaluation of an "intelligently coached simulation," the SINCGARS Tutor, that was developed to train military officers how to operate a SINCGARS radio. Posttests showed officers trained on the computerized tutor performed more accurately than a group trained on the actual equipment. (Author/LRW)
