This article describes the development and validation of the new CATSS (Computer Adaptive Test of Size and Strength), which measures vocabulary knowledge in four modalities -- productive recall, receptive recall, productive recognition, and receptive recognition. In the first part of the paper we present the assumptions that underlie the test --…

Many medical schools have adopted multiple mini-interviews (MMI) as an advanced selection tool. MMIs are expensive and used to test only a few dozen candidates per day, making it infeasible to develop a different test version for each test administration. Therefore, some items are reused both within and across years. This study investigated the…

This study explains mathematical difficulties of students who immigrated from the Former Soviet Union (FSU) vis-à-vis Israeli students, by identifying the existing bias factors in achievement tests. These factors are irrelevant to the mathematical knowledge being measured, and therefore threaten the test results. The bias factors were identified…

Two structural laws for intelligence tests are discussed: one law concerns the sign of correlation coefficients and gives conditions under which all correlations between test items will be positive; and one law concerns the relative sizes of the correlation coefficients between intelligence items. A cylindrical structure extends these laws. (SLD)

Discusses the comparison of groups of individuals who were administered different forms of a test. Focuses on the situation in which there is little overlap in content between the test forms. Reviews equating problems in national tests in Canada and Israel. (SLD)

Studied whether differential item functioning (DIF) in translated verbal items could be reduced or eliminated by revising these items. Results for six sections of an Israeli college admission test translated from Hebrew to Russian show that revisions can reduce DIF considerably. Discusses costs of the revision process. (SLD)

Focused on whether differential item functioning (DIF) is related to item type in translated test items and the causes of DIF using data from an Israeli college entrance test in Hebrew and a Russian translation. Results from 24,304 college applicants indicate that 34% of items functioned differently across items. (SLD)

Students' justifications for the three-item formats provided were compared. The study confirmed the usefulness of justifications as a diagnostic tool and offered recommendations regarding the use of justifications, including their use in the construction of two-tier items. (Author/CW)

When a test is translated from a source language to a target language, the result is generally not two psychometrically equivalent tests. If the sources of differential item functioning (DIF) across languages could be predicted, this could have important implications for test adaptations. This study examined item revision as a tool for improving…

A study conducted in Israel investigated the relevance of subject-specific reading passages to performance on reading comprehension tests for advanced university students of English as a second language. The research specifically examined (1) whether students performed better when the reading test content was directly related to their field of…

The proportionality model assumes that total testing time is proportional to the number of test items and the number of options per multiple choice test item. This assumption was examined, using test items having from two to five options. The model was not supported. (Author/GDC)

The multifaceted structure of sentence-completion test items was analyzed to explain verbal comprehension. The three stimulus constituents were technical, logical-semantic, and associative-contextual. Guttman's facet and order theories and smallest space analysis were used. Results confirmed the multiple skills involved in solving these tasks.…

A study of possible test bias in the Arabic and Hebrew versions of a standardized scholastic aptitude test used in Israel found a slight overprediction of performance for Arabs, but the findings appear to be more consistent with psychometric than cultural bias. (Author/MSE)
