This study examines performance differences between students with disabilities and students without disabilities students using differential item functioning (DIF) analyses in a high-stakes reading assessment. Results indicated that for Grade 9, many items exhibited DIF. Items that exhibited DIF were more likely to be located in the second half…

The information and assessment materials in these resources have been designed to assist teachers to gauge their own students' proficiency in Information and Communication Technologies (ICT) literacy. By examining modules from the National Year 6 and Year 10 ICT Literacy Assessment teachers may be able to design similar tasks and to judge their…

The purpose of this study was to develop general outcome measures (GOM) in mathematics so that teachers could focus their instruction on needed prerequisite skills. We describe in detail, the manner in which content-related evidence was established and then present a number of statistical analyses conducted to evaluate the technical adequacy of…

BRT Math Screening Measures focus on students' mathematics performance in grade-level standards for students in grades 1-8. A total of 24 test forms are available with three test forms per grade corresponding to fall, winter, and spring testing periods. Each form contains computation problems and application problems. BRT Math Screening Measures…

Previous studies have indicated that A-level students in the UK and Singapore have difficulty learning the topic of ionisation energy. A two-tier multiple-choice instrument developed in Singapore in an earlier study, the Ionisation Energy Diagnostic Instrument, was administered to A-level students in the UK, advanced placement high school students…

Psychometric properties and demographic correlates of a German form of R. W. Hubbard and J. L. McIntosh's (1992) Revised Facts on Suicide Quiz (RFOS), an inventory for assessing overall knowledge about suicide, were investigated in a sample of 1,093 Austrian medical and psychology students. Internal consistency of the RFOS was weak, as were many…

This article studies accessible assessment design to large-scale English language proficiency assessments that are now mandatory for elementary and secondary English language learners in public schools. Using a modified Delphi approach, a panel of 33 experts from the areas of assessment, English as a second language or bilingual education, and…

Computerized adaptive testing in personality assessment can improve efficiency by significantly reducing the number of items administered to answer an assessment question. Two approaches have been explored for adaptive testing in computerized personality assessment: item response theory and the countdown method. In this article, the authors…

The purpose of this study is to examine the effects of a false assumption regarding the motivation of examinees on test construction. Simulated data were generated using two models of item responses (the three-parameter logistic item response model alone and in combination with Wise's examinee persistence model) and were calibrated using a…

This article examined two item-writing guidelines: the format of the item stem and homogeneity of the answer set. Answering the call of Haladyna, Downing, and Rodriguez (2002) for empirical tests of item writing guidelines and extending the work of Smith and Smith (1988) on differential use of item characteristics, a mock multiple-choice driver's…

Within the context of behavioral economics, the ratio of response requirements to reinforcer magnitude is called "unit price." In this investigation, we yoked increases in reinforcer magnitude with increases in intervals of differential reinforcement of other behavior (DRO) to thin DRO intervals to a terminal value. (Contains 1 figure.)

If examinees are permitted to choose to answer a subset of the questions on a test, just knowing which questions were chosen can provide a measure of proficiency that may be as reliable as would have been obtained from the test graded traditionally. This new method of scoring is much less time consuming and expensive for both the examinee and the…

The present study is designed to cross-validate the findings of an earlier component analysis of orthographic-projection, spatial-ability items. The earlier research identified four design components that contribute to the difficulty of orthographic-projection items. The research found that increasing Rasch item difficulties on component…

In actual test development practice, the number of test items that must be developed and pretested is typically greater, and sometimes much greater, than the number eventually judged suitable for use in operational test forms. This has proven to be especially true for analytical reasoning items, which currently form the bulk of the analytical…

A procedure for checking the score equivalence of nearly identical editions of a test is described. The procedure employs the standard error of equating (SEE) and utilizes graphical representation of score conversion deviation from the identity function in standard error units. Two illustrations of the procedure involving Scholastic Aptitude Test…
