Technological Pedagogical Content Knowledge, one of the frameworks proposed in order to popularize the use of technology in a classroom environment, has been customized and has taken the form of Web Pedagogical Content Knowledge. The Relational Screening Model was used in this study. It aims to determine whether a profile of preservice teachers…

This paper discusses how a seldom-used statistical procedure, recursive regression (RR), can numerically and graphically illustrate data-driven nonlinear relationships and interaction of variables. This routine falls into the family of exploratory techniques, yet a few interesting features make it a valuable compliment to factor analysis and…

Some interpretations of relative variable importance in the contexts of multivariate analysis of variance (MANOVA) and discriminant analysis (DA) are presented. Some indices potentially useful for the interpretations are presented, and the assessment of variable importance is illustrated using real data sets. Both descriptive discriminant analysis…

The use of Procrustean rotation as a procedure for assessing the invariance of study results is proposed. Researchers have long relied on significance testing as a measure of judging the worthiness of empirical findings. However, significance testing has come under fire because it does not provide information about the importance or replicability…

Presents an overview of diffusion theory and the attributes of innovations and their adopting units, as well as the methodology and results of a study designed to increase understanding of innovative behavior by investigating perceptions of both adopters and nonadopters of the consumer-oriented videotex service, Channel 2000.

The objective of this study was to identify those cognitive characteristics that best differentiate the Navy's Basic Electricity and Electronics (BE/E) Preparatory School graduates and failures. Subjects included 207 BE/E students--172 graduates and 35 failures. Before these trainees had commenced BE/E School, they were administered six tests of…

An alternative approach for program evaluation of small, specialized programs when comparison groups are not available is described. This application is illustrated by presenting the results of an analysis of data from Project Talent, a national manpower study, and discussing its application to the evaluation of a medical training program.…

Variables from five domains--demography, social background, service history, satisfaction, and performance--were used in a discriminant analysis approach to distinguishing three groups of naval personnel. Potential usefulness of this method, including implications for better understanding and control of manpower turnover were discussed. (Editor)

This study was concerned with various schemes for reducing the number of variables in a multivariate analysis. Two sets of illustrative data were used; the numbers of criterion groups were 3 and 5. The proportion of correct classifications was employed as an index of discriminatory power of each subset of variables selected. Of the four procedures…

This paper is concerned with the identification and testing of salient variables which show potential for explaining client use of evaluation information. A single-page interview instrument was devised which aggregated the factors and factor categories collected following an extensive review of the literature. Data were collected from a…

A study using discriminant analysis to correct bias in predicting faculty rank is reported. Findings concerning the relationship of prediction error and gender and suggestions for use of the results to study salary-bias problems are also discussed. (Author/MSE)

Change Group Analysis is suggested as a technique for examining the correlates of the differential effects of a compensatory education program within the group of enrolled pupils. It is based on using pretest-posttest relative changes for forming criterion groups and then using multiple disciminant analysis to uncover patterns of predictor…
