This study presents a generalized version of the residual differential item functioning (RDIF) detection framework in item response theory, named GRDIF, to analyze differential item functioning (DIF) in multiple groups. The GRDIF framework retains the advantages of the original RDIF framework, such as computational efficiency and ease of…

Assessment is an integral part of any teaching learning process. Assessment has large number of functions to perform, whether it is formative or summative. This paper analyse the issues involved and the areas of concern in the classroom assessment practice and discusses the recent reforms take place. [This paper was published in Edutracks v20 n8…

In this study we examined variations of the nonequivalent groups equating design for tests containing both multiple-choice (MC) and constructed-response (CR) items to determine which design was most effective in producing equivalent scores across the two tests to be equated. Using data from a large-scale exam, this study investigated the use of…

The problem of test bias has been a growing concern in recent years. Of the several available methods for determining test bias, probably the most effective means involves collecting criterion information. This data collection process often provides a considerable barrier to the researcher, especially for the small test user and for someone who…

Selective Testing provides students with equivalent test options that control the sequence and quantification of individual items. Essay and objective test construction is modified to allow the student to combine units and create an individualized test. An example of a test on the American Revolution is presented. (FG)

Utilizing eight apprentices in the mentals trades, this study empirically evaluated a number of techniques designed to produce performance tests that are economically feasible, reliable, content-valid, and less disadvantageous to minority group members than paper-and-pencil measures. The final test was economically feasible, reliable with respect…

In this analysis of intelligence testing of minority group children, the implications of inadequate testing practices are discussed. Several aspects of test design are examined: deficiencies in intelligence testing, cultural bias, construct validity, and diagnostic utility. A sample set of results derived from a Stanford-Binet test administered to…

"Educational Measurement" has been the bible in its field since the first edition was published by ACE in 1951. The importance of this fourth edition of "Educational Measurement" is to extensively update and extend the topics treated in the previous three editions. As such, the fourth edition documents progress in the field and…

Adult educators in the state of New Jersey have expressed concern about the adequacy of the 1978 General Educational Development (GED) test. Based on these concerns research was conducted in the use and applicability of the current GED test. The project investigated whether the existing GED test was meeting the needs of the large majority of GED…
