The need to increase US competitiveness in the world economy is a driving factor in the recent push to internationalize university campuses across the country. Technical and subject area expertise are no longer sufficient to succeed in the 21st-century global workplace. Intercultural competence is becoming more valued as part of the desired…

Written by a social worker for social work students, this is a nuts and bolts guide to statistics that presents complex calculations and concepts in clear, easy-to-understand language. It includes numerous examples, data sets, and issues that students will encounter in social work practice. The first section introduces basic concepts and terms to…

On the basis of a review of the literature and the results of three experiments with dog experts, Robbins and McKone [Robbins, R. A., & McKone, E. (2006). No face-like processing for objects-of-expertise in three behavioural tasks, "Cognition"] argue that there is little or no evidence supporting an expertise account of the differences in…

This report describes the midterm and final tests administered to pupils in the Quality Assurance classes using the First Year Communication Skills Program. The tests included both selected and constructed response items and were designed to be individually administered to pupils. The results are reported for each eight outcome subscores (selected…

This research investigated the use of the Rasch simple logistic model in obtaining test-free ability estimates. Tests employing word, picture, symbol and number analogies were administered to college and high school students. The results show that the Rasch model does not offer an improvement over the use of percentile ranks in estimating…

The purposes of this study were to examine and evaluate the importance of three variables of Bloom's mastery learning model. The variables studied were specification of objectives, use of diagnostic-progress (d-p) tests, and use of alternate resources. The study used four seventh grade and four eighth grade classes; each grade classes were…

Problems of scale typically arise when comparing test score trends, gaps, and gap trends across different tests. To overcome some of these difficulties, we can express the difference between the observed test performance of two groups with graphs or statistics that are metric-free (i.e., invariant under positive monotonic transformations of the…

Utilizing the Test of English Proficiency, developed by Seoul National University (TEPS), examined comparability between the paper-based language test and the computer-based language test based on content and construct validation employing content analyses based on corpus linguistic techniques in addition to such statistical analyses as…

Researchers sometimes need a statistical test of the hypothesis that two values of Cronbach's alpha reliability coefficient are equal. The situation may involve scores from two different measures administered to independent random samples or from the same measure administered to random samples from two different populations. Feldt derived a test…

The study investigated the effect of note-taking on comprehension of lectures by 44 undergraduate EFL students who are in the first year of their undergraduate level in the Department of Foreign Language Education in Middle East Technical University. The participants were divided into two groups, namely experimental and control groups. The…

The underachievement of ethnic minority youth from disadvantaged neighborhoods is a pervasive educational issue this nation is facing. Based on an ecological perspective, we examined the contextual effects of neighborhood ethnic density and neighborhood disadvantage on the academic achievement of Hmong immigrant youths. Utilizing hierarchical…

The gold standard in making causal inference on program effects is a randomized trial. Most randomization designs in education randomize classrooms or schools rather than individual students. Such "clustered randomization" designs have one principal drawback: They tend to have limited statistical power or precision. This study aims to…

Too few researchers understand what statistical significance testing does and does not do, and consequently their results are misinterpreted. This Digest explains the concept of statistical significance testing and discusses the meaning of probabilities, the concept of statistical significance, arguments against significance testing,…

The Rasch item analysis model is supposed to yield norm-free estimates of ability and easiness values, but there are several possible interpretations of the nature and extent of such norm-freeness. One such interpretation was that to involve the scores of one single experimental group of testees which were embedded in four differently skewed…

A discussion of selected applications of new tests developed within the context of a large-scale curriculum for educable mentally retarded (EMR) children, the Social Learning Curriculum (SLC), is presented in this paper which investigates three types of reliability that need to be demonstrated in order to provide a basis of these applications. The…
