Confucius pointed out that the first step toward wisdom is calling things by the right name. The term "Differential Item Functioning" (DIF) did not arise fully formed from the miasma of psychometrics, it evolved from a variety of less accurate terms. Among its forebears was "item bias" but that term has a pejorative connotation…

In his 2003 article in the "Harvard Educational Review" (HER), Freedle claimed that the SAT was both culturally and statistically biased and proposed a solution to ameliorate this bias. The author argued (Dorans, 2004a) that these claims were based on serious computational errors. In particular, he focused on how Freedle's table 2 was…

In their paper "Unfair Treatment? The Case of Freedle, the SAT, and the Standardization Approach to Differential Item Functioning" (Santelices & Wilson, 2010), the authors studied claims of differential effects of the SAT on Latinos and African Americans through the methodology of differential item functioning (DIF). Previous…

Santelices and Wilson (2010) claimed to have addressed technical criticisms of Freedle (2003) presented in Dorans (2004a) and elsewhere. Santelices and Wilson's abstract claimed that their study confirmed that SAT[R] verbal items do function differently for African American and White subgroups. In this commentary, I demonstrate that the…

In this commentary, the author discusses two recent replications (Santelices & Wilson, 2010; Scherbaum & Goldstein, 2008) of some of his earlier work on SAT items using the differential item functioning (DIF) statistic wherein he contrasted the test performance of African American examinees with White examinees (Freedle, 2003). In this…

This paper is the transcript of a talk given to those who use test information but who have little technical background in test theory. The concepts of modern test theory are compared with traditional test theory, as well as a probable future test theory. The explanations given are couched within an extended metaphor that allows a full description…

In educational testing, one is concerned to get as much information as possible about a given examinee from each minute of testing time. Maximum information is obtained when the difficulty of each test exercise matches the estimated ability level of the examinee. The goal of adaptive testing is to accomplish this. Adaptive patterns are reviewed…

Research has shown that multiple-choice questions formed by transforming or paraphrasing a reading passage provide a measure of student comprehension. It is argued that similar transformation and paraphrasing of lesson questions is an appropriate way to form parallel multiple-choice items to be used as a posttest measure of student comprehension.…

An alternate-choice test item is a simple declarative sentence, one portion of which is given with two different wordings. For example, "Foundations like Ford and Carnegie tend to be (1) eager (2) hesitant to support innovative solutions to educational problems." The examinee's task is to choose the alternative that makes the sentence…

The item bank (Rasch model) has serious limitations for the national assessment of subject performance: it requires agreement about the scope and organization of each school subject and about the difficulty level of each test item; and items tend to focus on factual knowledge, ignoring other desirable learning outcomes.

This article discusses the application of the Golden Rule procedure to items of the Scholastic Aptitude Test. Using item response theory, the analyses indicate that the Golden Rule procedures are ineffective in detecting biased items and may undermine the reliability and validity of tests. (Author/JAZ)

Extends dynamic model of cognitive growth proposed by van Geert in three directions: (1) added a term to consider exposure to material to be learned; (2) developed method to apply model to cross-sectional studies; and (3) developed procedure to scale cognitive abilities tests with items of varying difficulty. Tests model with 2- to 15-year-olds'…

This paper argues that no single measurement strategy serves all purposes and that applying methods and techniques which allow a variety of data elements to be retrieved and juxtaposed may be an investment in the future. Item response theory, Rasch model, and latent trait theory are all approaches to a single conceptual topic. An abbreviated look…

The merits and hazards of minimum competency testing for the individual student or for student groups are discussed. Types of groups which lend themselves to group application and some important factors in determining the parameters of a group are discussed. Ten critical issues related to minimum competency testing are identified: (1) scope of…
