The purpose of this City Data study was to explore sources of data outside the National Evaluation study of Follow Through to determine the usefulness of such information in the overall assessment. The two major objectives of the study were to judge the representativeness of the Project Follow Through sample and to check on the credibility of…

Various aspects of Confidence Weighting are examined. Variant of Confidence Weighting, its effect on test reliability, and the validity of Confidence Weighting are discussed. (DG)

Experimental results indicate that: (1) the Teaching Situation Reaction Test has potential for predicting inservice social studies teachers' verbal and cognitive classroom behavior patterns; and (2) these patterns are related to current developments in social studies instruction. (MS)

A summary is provided of the rationale for questioning the applicability of classical reliability measures to criterion referenced tests; an extension of the classical theory of true and error scores to incorporate a theory of dichotomous decisions; a presentation of the mean split-half coefficient of agreement, a single-administration test index…

Describes two QuickBASIC programs that provide students direct experience with interpreting correlation scatter-plots. Maintains that the programs can be used in classroom exercises to highlight factors that influence the size of a Pearson correlation coefficient. (CFR)

Describes a QuickBASIC program for demonstrating the differences between main effects and interactions in factorial designs. The program can be used in conjunction with a traditional lecture to improve student understanding and develop skills in recognizing main effects and interactions from graphic displays. (CFR)

Discusses the evaluation of second and foreign language programs, focusing on whether such evaluations should be summative or formative; use outside experts or program staff; emphasize qualitative or quantitative data; and concentrate on the process or the product. An annotated bibliography discusses six important works in the field. (78…

Researchers studying monitoring accuracy currently use two different indexes to estimate accuracy: relative accuracy and absolute accuracy. The authors compared the distributional properties of two measures of monitoring accuracy using Monte Carlo procedures that fit within these categories. They manipulated the accuracy of judgments (i.e., chance…

Understanding that the behavior of people takes place within a context, over the past 20 years research in education and the sport sciences has witnessed an increasing development of multilevel frameworks that are both conceptually and methodologically sound. Despite these advances, the use of multilevel models and research designs in education…

Statistically based risk assessment devices are widely used in criminal justice settings. Their promise remains largely unfulfilled, however, because assumptions and premises requisite to their development and application are routinely ignored and/or violated. This article provides a brief review of the most salient of these assumptions and…

This study reviews the literature on the social and behavioral characteristics of only children in China. Of 16 studies that reported differences in the characteristics of only and non-only children, only 2 indicated that only children exhibited more socially desirable behaviors than did non-only children. The remaining studies reported that,…

The problem of determining optimal test lengths with fixed total testing time has proved to be a difficult one for criterion-referenced test developers. An algorithm is needed which can be used by test developers to allocate available testing time to maximize the validity of their total criterion-referenced tests or testing programs. To be…

Educators designing procedures for identifying students as learning disabled are faced with serious technical difficulties. A student with a learning disability is one who "has a severe discrepancey between achievement and intellectual ability" in one or more designated areas. The methods of quantifying achievement, intellectual ability,…

Previous research has studied the effects of different methods of item option weighting on the reliability and concurrent and predictive validity of achievement tests. Increases in reliability are generally found, but with mixed results for validity. Several methods of producing option weights, (i.e., Guttman internal and external weights and…

To evaluate the accuracy of the 1970 census' occupational classification system, a comparison was made between that year's responses to census questions and the replies by the same population group to the 1972 Postcensal Manpower Survey (PMS). Each of these questionnaires relied on a different methodology; in the PMS the respondent classified…
