Effects of altering test difficulty on examinee ability measures and test length in a computer adaptive test were studied for 225 medical technology students in 3 test difficulty conditions. Results suggest that, with an item pool of sufficient depth and breadth, acceptable targeting to test difficulty is possible. (SLD)

Effectiveness of the Mantel-Haenszel statistic in detecting differentially functioning test items was studied when the internal criterion was varied, using a dataset from a life skills examination taken by 1,000 Anglo-American and 1,000 Native American high school students. Choice of criterion variable has a substantial effect on detection. (SLD)

Methods used by adults to read numerals were investigated by asking graduate students in education to read and solve mathematics problems. Eye movement studies noted reading patterns. Distinct first reading and rereading phases and two distinct methods of reading numerals were identified. (SLD)

Discusses the process of developing a communicative reading/writing test based on authentic materials for university students in economics, political science, or law who are nonnative English speakers. (27 references) (CFM)

The reliability and validity of multiple-choice tests were computed as a function of the number of options per item and student ability for 435 parochial high school juniors, who were administered the Washington Pre-College Test Battery. Results suggest the efficacy of the three-option item. (SLD)

A procedure for interpreting multiple-discrimination indices from a multidimensional item-response theory analysis is described and demonstrated with responses of 1,635 high school students to a multiple-choice test. The procedure consists of converting discrimination parameter estimates to direction cosines and analyzing the angular distances…

Three different differential item functioning (DIF) detection methods were used to examine the extent to which items in a mathematics performance assessment functioned differently for matched gender groups from a sample of 1,782 sixth and seventh graders. Implications of the finding that two items were potentially biased are discussed. (SLD)

Skill in reading diverse genres of scientific texts, including media reports, is an important aspect of scientific literacy that some experts argue should be included in the science curriculum. To understand current and potential uses of media reports in classrooms, we conducted research in three areas. First, we examined major science education…

Technology today offers many new opportunities for innovation in educational assessment through rich new assessment tasks and potentially powerful scoring, reporting and real-time feedback mechanisms. One potential limitation for realizing the benefits of computer-based assessment in both instructional assessment and large scale testing comes in…

The aim of this study was to develop a means of tracking the reading performance of low-progress readers on a weekly basis, so as to inform instructional decision-making. A representative sample of 261 primary school children from Years 1 to 5 were tested on 21 different text passages taken from a developing passage reading test, the Wheldall…

There are indications that the new technologies could have radical implications for conventional teaching and learning processes. It notes that, in reconfiguring how teachers and learners gain access to knowledge and information, the new technologies challenge conventional conceptions of both teaching and learning materials, and teaching and…

In this technical report, we describe the development and piloting of a series of mathematics progress monitoring measures intended for use with students in grades kindergarten through eighth grade. These measures, available as part of easyCBM[TM], an online progress monitoring assessment system, were developed in 2007 and 2008 and administered to…

The purpose of the study was to investigate whether selected test and item characteristics in the Scholastic Aptitude Test (SAT) are associated with unexpected differential item functioning (DIF) for males and females and for majority and minority group members (i.e., White performance compared with Black, Asian American, Hispanic American, and…

This packet contains a textbook, an instructor's guide, and a student workbook for a course on conducting financial investigations to detect and solve crimes. The topics covered in the 11 chapters of the textbook and the ancillaries are the following: (1) why financial investigation?; (2) laws related to financial crimes; (3) evidence; (4) sources…

Item response theory (IRT) has been used extensively to study differential item functioning (dif) and to identify potentially biased items. The use of IRT for diagnostic purposes is less prevalent and has received comparatively less attention. This study addressed differential objective function (dof) to identify potentially biased content units.…
