As one of the important stakeholders in the academic process, students and their preferences should be considered when the instructor selects the various course design features. Although students are not the only stakeholders in the academic process, their receptiveness to classroom instruction is clearly a central focus of that process. This…

The classification problem in educational testing is a decision problem. One must assign subjects to one of several available treatments on the basis of test scores, where the success of each treatment is measured by a different criterion. Examples of classification decisions include individualized instruction, counseling, and clinical settings.…

This handbook treats a restricted set of statistical procedures for addressing some of the most prevalent technical issues that arise in domain-referenced testing. The procedures discussed here were chosen because they do not necessitate extensive computations. The five major sections of the paper cover: (1) item analysis procedures for using data…

A theoretical model is developed for analysis of intervention effects in multiple autocorrelated time-series which may be classified or blocked two ways. The intervention effect is estimated independently for each series. The estimates are then entered as observations in two-factor analysis of variance with one observation per cell, utilizing a…

Eight discriminators were identified and data were obtained from the records of 80 graduate students who attained one of four achievement levels at the conclusion of a beginning course in educational statistics. Although the internal discriminatory power of the set of eight measures was very high, estimates of the true power were discouragingly…

This final report indicates the general areas of investigation in a program of research in the prediction of personal adjustment, conducted over a seventeen-year period. The crucial problems in the prediction of personal adjustment are fundamentally concerned with the data matrix which reflects the experimental designs and displays the essential…

Authors of the taxonomy made various claims about its properties that concern both educational and psychological issues; these claims have stimulated investigations of the taxonomy's validity. As the taxonomy is now entering its twenty-second year, this review attempts to survey these investigations and appraise the findings. (Author/CP)

The difficulties in collecting data on library inventories and expenditures are discussed first by Heron in a reply to Machlup's earlier book, and then by Machlup in a rebuttal. (LBH)

The methodology employed in fourteen motivational orientation studies is reviewed. All studies used either the Education Participation Scale, the Continuing Learning Orientation Index, or the Reasons for Educational Participation Scale. Issues discussed concern factor scoring, factor analysis, rotation, scaling, reliability, and the extent to…

Five problems involved in the task of presenting a number of different education systems in statistical terms that are meaningful and useful to educational researchers, planners, and laymen are discussed. They include developing a classification system and conversion guides, providing a framework for updating work, and coordination among…

Presents a method to improve client classification. Reviews clinical prediction models and statistical prediction issues. In classifying clients for remedial services, utility of the prediction scheme depends on gains accrued by its use over program base rates and relative cost. This assumes that differential treatments parallel diagnostic…

Errors of misclassification and their effects on categorical data analysis are discussed. The chi-square test for equality of two proportions is examined in the context of errorful categorical data. The effects of such errors are illustrated. A correction procedure is developed and discussed. (Author/MH)

When 43 experienced school psychologists were asked to evaluate discrepancy scores, it was found that they made inconsistent choices, failed to use standard statistical procedures for testing differences between scores, and tended to misinterpret percentile ranks as useful for discrepancy analysis. Implications for learning-disabilities…

American Sign Language uses the face to express vital components of grammar in addition to the more universal expressions of emotion. The study of ASL facial expressions has focused mostly on the perception and categorization of various expression types by signing and nonsigning subjects. Only a few studies of the production of ASL facial…

The comments presented here were made after the presentation of four papers and commentary by two other symposium participants. They address issues in language comparison and classification. First, comments are made on the papers ("An African Test Case in Comparative Methodology,""The Mathematics of Multilateral Comparison,""Testing a Basic…
