This study introduces the first Arabic Vocabulary Levels Test (Arabic-VLT), created for foreign learners of Arabic. We present compelling evidence to substantiate its validity and reliability. The Arabic-VLT was developed according to five levels, beginning with the most frequently used words (Level 1) to the least frequently used ones (Level 5),…

Diploma and degree completion have become the fundamental standard for judging the performance of secondary and postsecondary educational institutions. Increasingly, leaders of education and workforce policy and programs assume that these measures of attainment effectively serve as indicators of adequate levels of essential literacy and numeracy…

This paper includes a nontechnical description of methods for calculating effect sizes in intellectual and developmental disability studies. Different hypothetical studies are used to illustrate how null hypothesis significance testing (NHST) and effect size findings can result in quite different outcomes and therefore conflicting results. Whereas…

Districts now have access to a wealth of new information that can help target students with appropriate supports and bring focus and coherence to college readiness efforts. However, the abundance of data has brought its own challenges. Schools and school systems are often overwhelmed with the amount of data available. The capacity of districts to…

Male perpetrated sexual aggression has long been recognized as a serious problem on college campuses. The purpose of this multiple regression correlation study was to assess the relationship between levels of moral development (measured by the Defining Issues Test) and the degree to which first-year college men (N = 161) ascribed to rape…

This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

Recent work has shown that multidimensionally scoring responses from different tests can provide better ability estimates. For educational assessment data, applications of this approach have been limited to binary scores. Of the different variants, the de la Torre and Patz model is considered more general because implementing the scoring procedure…

Recent research shows that U.S. 15-year-olds are behind their international counterparts in problem solving and mathematics literacy, ranking 24th of 29 nations (Lemke et al. 2004). Therefore, a key concern among policymakers and educators is improving the quantitative and analytical skills of American youth, who face job prospects in an economy…

Thirty-five gifted elementary children were tested with the Wechsler Intelligence Scale for Children III (WISC-III) and results were compared to a previous administration of the WISC (Revised). Scores were significantly higher on all three WISC-R global scales and most subtest scaled scores. Correlation coefficients between the tests were…

Describes a study that examined the relationship between academic ability or aptitude, as measured by grade point average and American College Test scores, and achievement with and without computer-assisted instruction. (15 references) (CLB)

The decline in standardized test scores during the 1960s and 1970s is well documented and is seen in both aptitude and achievement test scores. This paper describes and analyzes the test score trends over the 1960s, 1970s and early 1980s for five aptitude tests: (1) the Scholastic Aptitude Test; (2) the American College Test; (3) the Preliminary…

The No Child Left Behind Act of 2001 mandated statewide accountability testing and focused the accountability conversation on reading. Therefore, the current study examined the relationship between curriculum-based measurement for reading (R-CBM) and state accountability test scores, potential grade differences in relationship magnitude, and…

Attitude measures frequently produce distributions of item scores that attenuate interitem correlations and thus also distort findings regarding the factor structure underlying the items. An actual data set involving 260 adult subjects' responses to 55 items on the Love Relationships Scale is employed to illustrate empirical methods for…

This paper explores the functioning of the low-inference observation system used as part of the Tennessee Career Ladder evaluation system, which provides teachers with the opportunity to qualify for additional pay on the basis of outstanding performance. The analysis of the functioning of this form is intended to provide the basis for the ongoing…

This study is an attempt at a cohesive characterization of the concept of essay reliability. As such, it takes as a basic premise that previous and current practices in reporting reliability estimates for essay tests have certain shortcomings. The study provides an analysis of these shortcomings--partly to encourage a fuller understanding of the…
