Could the research you read be fundamentally flawed? Could critical defects in methodology slip by you undetected? To become informed consumers of research, students need to thoughtfully evaluate the research they read rather than accept it without question. This second edition of a classic text gives students the tools they need to apply critical…

The state of Texas has committed to increased access to Higher Education (HE) for all state residents. Among the steps Texas has undertaken to raise inclusion is specific attention to equitable placement testing in community colleges. The purpose of this study was to determine if placement is affected by the instrument applicants use,…

Many states have responded to teacher shortages by granting certification to individuals traditionally prepared out-of-state; now, out-of-state prepared teachers comprise a sizable percentage of the teacher workforce in many states. We know little about these teachers, and therefore, in the present study, we estimate the effectiveness of…

There are so many different intervention programs for educators to use to increase the reading achievement of below grade level students, that it can often be difficult to choose the appropriate one for the students. Most programs are scripted and are used with small groups of students. Reading Recovery is not a scripted program and is taught in a…

Creative self-concept has become a notable construct of interest in creativity literature in the last decade. The predictors, correlates, determinants, and consequences of self-rated creativity, creative self-efficacy, creative personal identity, and creative metacognition--as well as other self-concept constructs--have been studied intensively,…

Classification consistency and accuracy are viewed as important indicators for evaluating the reliability and validity of classification results in cognitive diagnostic assessment (CDA). Pattern-level classification consistency and accuracy indices were introduced by Cui, Gierl, and Chang. However, the indices at the attribute level have not yet…

Computer-assisted personal interviewing (CAPI) offers many attractive benefits over paper-and-pencil interviewing. There is, however, mixed evidence on the impact of CAPI on interview "length," an important survey outcome in the context of length limits imposed by survey budgets and concerns over respondent burden. In this article,…

The case is presented of an 8-year-old boy who was referred for psycho-educational assessment because of difficulties with writing. The article provides an example of the way in which a case unfolds as further assessment data become available, and describes a number of challenging aspects of the assessment process. In this case, dilemmas arose…

Infants have shown variable success in quantity comparison tasks, with infants of a given age sometimes successfully discriminating numerical differences at a 2:3 ratio but requiring 1:2 and even 1:4 ratios of change at other times. The current explanations for these variable results include the two-systems proposal--a theoretical framework that…

This study investigates the hypothesis that there is a natural number bias that influences how students understand the effects of arithmetical operations involving both Arabic numerals and numbers that are represented by symbols for missing numbers. It also investigates whether this bias correlates with other aspects of students' understanding of…

Michael Kane writes in this article that he is in more or less complete agreement with Professor Koretz's characterization of the problem outlined in the paper published in this issue of "Measurement." Kane agrees that current testing practices are not adequate for test-based accountability (TBA) systems, but he writes that he is far…

Theories of relational concept acquisition (e.g., schema induction) based on structured intersection discovery predict that relational concepts with a probabilistic (i.e., family resemblance) structure ought to be extremely difficult to learn. We report four experiments testing this prediction by investigating conditions hypothesized to facilitate…

In educational testing, differential item functioning (DIF) statistics must be accurately estimated to ensure the appropriate items are flagged for inspection or removal. This study showed how using the Rasch model to estimate DIF may introduce considerable bias in the results when there are large group differences in ability (impact) and the data…

The invited colloquium on New Directions in Language Assessment held at the American Association for Applied Linguistics (AAAL) annual meeting in Portland, Oregon on March 22, 2014 brought together an international panel of scholars to together explore the possibilities and challenges of translanguaging and bi/multilingual approaches in…

Two practical activities are described, which aim to support critical thinking about statistics as they concern multiple outcomes testing. Formulae are presented in Microsoft Excel spreadsheets, which are used to calculate the inflation of error associated with the quantity of tests performed. This is followed by a decision-making exercise, where…
