The primary goal of teaching is to successfully facilitate learning. Testing can help accomplish this goal in two ways. First, testing can provide a powerful motivation for students to prepare when they perceive that the effort involved leads to valued outcomes. Second, testing can provide instructors with valuable feedback on whether their…

The aim of this study was to compare the small sample (N = 1, 3, 5, 10, 15) performance of a Bayesian multivariate vector autoregressive (BVAR-SEM) time series model relative to frequentist power and parameter estimation bias. A multivariate autoregressive model was developed based on correlated autoregressive time series vectors of varying…

This study examines a 118-year continuous record of retention and graduation rates at a public university for long-term trends not observable in shorter studies. While the first year retention rates stayed level over much of this period, second year rates increased steadily by 1.2% per decade. In contrast, graduation rates at 4 years compared to 6…

An in-class activity is described that can be used not only to motivate hypothesis testing, but also to understand and compute the p-value and power in a statistical test. (Contains 3 figures.)

Common rates employed in classificatory testing are the true positive rate (TPR), false positive rate (FPR), positive predictive power (PPP), and negative predictive power (NPP). FPR and TPR are estimated from research samples representing populations to be distinguished by classificatory testing. PPP and NPP are used by clinicians to classify…

This essay updates the two articles that were previously published in the Winter 1975/1976 and 1984 issues respectively of "Education Libraries," and featured the Educational Testing Service (ETS) Test Collection. At the time of the writing of the 1975/1976 article, the collection was known as The ETS Test Collection. However, since the collection…

In computerized adaptive testing (CAT), ensuring the security of test items is a crucial practical consideration. A common approach to reducing item theft is to define maximum item exposure rates, i.e., to limit the proportion of examinees to whom a given item can be administered. Numerous methods for controlling exposure rates have been proposed…

Michael Russell, Thomas Hoffmann, and Jennifer Higgins describe how the principles of universal design were applied to the development of an innovative computer-based test delivery system, NimbleTools, to meet the accessibility and accommodation needs of students with a wide range of disabilities and special needs. Noting the movement to…

Nigeria has embraced the Open and Distance Learning (ODL) mode of education in order to make education affordable and to reach the teaming population of qualified citizens yearning to have quality education but are left out of it. Most universities in the country run the single mode conventional system of education; some run the dual mode while…

An accurately calibrated item bank is essential for a valid computerized adaptive test. However, in some settings, such as occupational testing, there is limited access to test takers for calibration. As a result of the limited access to possible test takers, collecting data to accurately calibrate an item bank in an occupational setting is…

Using personal narratives and research on teacher "communities of practice," the authors outline a proactive response to high-stakes testing policies that places teacher learning at its center. Although research on the effects of these policies is mixed, the authors are troubled by the ways in which the policies have been used to strip teachers of…

Many postsecondary institutions currently administer standardized tests of general college outcomes; more than a quarter of Association of American Colleges and Universities (AAC&U) member institutions do so. Using standardized tests for accountability purposes has been contentious mainly because these tests do not measure every important…

A clear understanding of basic gene structure is critical when teaching molecular genetics, the central dogma and the biological sciences. We sought to create a gene-based teaching project to improve students' understanding of gene structure and to integrate this into a research project that can be implemented by instructors at the secondary level…

In "Updating the Duplex Design for Test-Based Accountability in the Twenty-First Century," Bejar and Graf (2010) propose extensions to the duplex design for large-scale assessment presented in Bock and Mislevy (1988). Examining the range of people who use assessment results--from students, teachers, administrators, curriculum designers,…

We provide a response to a commentary by Wiers and Stacy (2010) on our model of the alcohol-behavior link (Moss & Albery, 2009). Whereas Wiers and Stacy generally supported our model, they took issue with our conceptualization of the alcohol expectancy construct. We address the major concerns of Wiers and Stacy by demonstrating that our own view…
