A commitment to pursue problems from multiple angles, methods, and theoretical positions means that research teams require strategies to navigate the tensions and conflict that inevitably emerge, particularly when the intent is to find ways to integrate different disciplinary perspectives.

Preventing items in adaptive testing from being over- or underexposed is one of the main problems in computerized adaptive testing. Though the problem of overexposed items can be solved using a probabilistic item-exposure control method, such methods are unable to deal with the problem of underexposed items. Using a system of rotating item pools,…

Although Q methodology has been especially well used by researchers in a variety of social and behavioral sciences, student affairs researchers have not been inclined to deploy this methodology. This article examines Q methodology and uses a case study to explore the potential for student affairs assessment and research. Overall, the authors…

A Monte Carlo study examined the statistical performance of single sample and bootstrap methods that can be used to test and form confidence interval estimates of indirect effects in two cluster randomized experimental designs. The designs were similar in that they featured random assignment of clusters to one of two treatment conditions and…

Recently, nonparametric methods have been proposed that provide a dimensionally based description of test structure for tests with dichotomous items. Because such methods are based on different notions of dimensionality than are assumed when using a psychometric model, it remains unclear whether these procedures might lead to a different…

Many important research hypotheses concern conditional relations in which the effect of one predictor varies with the value of another. Such relations are commonly evaluated as multiplicative interactions and can be tested in both fixed-and random-effects regression. Often, these interactive effects must be further probed to fully explicate the…

In the context of reviewing an article for this journal (van der Linden & Sotaridona, this issue, pp. 283-304) the topic of unconditional and conditional hypothesis testing came under consideration. While this is hardly a new issue (consider, for example, arguments regarding the chi square vs. Fisher exact test of independence for a 2 x 2…

The authors propose new procedures for evaluating direct, indirect, and total effects in multilevel models when all relevant variables are measured at Level 1 and all effects are random. Formulas are provided for the mean and variance of the indirect and total effects and for the sampling variances of the average indirect and total effects.…

There has been renewed discussion of the scientific method, with many voices arguing that it presents a very limited or even wholly incorrect image of the way science is really done. At the same time, the idea of a scientific method is pervasive. This article identifies the scientific method as a simple model for the process of scientific inquiry.…

Medicine is a profession with a long history of research and high standards of methodological rigour and evidence-based decision making. These standards are being transferred into medical education. Universities are starting to collect high-quality data on their admissions systems. This has not been a short-term proposition. Medical courses are…

The purposes of this study were to (a) identify how leadership in a successful rural school districts has helped raise student achievement levels beyond those of comparable school districts as measured by state and federal mandated test scores, (b) investigate the district leadership that aligns with identified effective practices, and (c)…

This paper presents qualitative research completed in two groups of hospitals in the United Kingdom, as part of a larger mixed methods study. It involved eight qualified nurses caring for patients with gastro-intestinal cancer in general surgical wards. It explored the nurses' experiences of using an online programme and their perceptions of the…

This research aimed at developing a methodological framework to investigate the alignment of the Lebanese national math exam tests with the curriculum at the middle school level, during the transitory period of a major curricular reform. The focus is on exploring the characteristics of an "assessment culture" set by the national exams…

Frank Aydelotte is best remembered for developing in the 1930s and 1940s the nation's most innovative and influential honors program, based on the education he received as a Rhodes Scholar at Oxford. As coordinator of freshman English at Indiana University, Aydelotte attacked the dominant Harvard model of instruction while promoting a method…

Based on the idea that certain critical skills mark the thoughtful person, inform the workplace, and provide for lifelong learning, this book provides classroom teachers with the ability to teach various subjects to students in a manner that simultaneously develops students' critical thinking, reading, writing, listening, and speaking skills. A…
