The focus article by Coburn and Turner (this issue) seeks to provide a comprehensive framework for understanding data use in the context of data-use interventions. This commentary focuses on what the authors see as a glaring omission in what is otherwise a valuable framework: the issue of "useful data." It is their contention that the usefulness…

A simulation study compared the performance of robust normal theory maximum likelihood (ML) and robust categorical least squares (cat-LS) methodology for estimating confirmatory factor analysis models with ordinal variables. Data were generated from 2 models with 2-7 categories, 4 sample sizes, 2 latent distributions, and 5 patterns of category…

Praxeological research is a necessary contribution to the research field in early childhood education and care, which is currently dominated by an evidence-based paradigm that tends to consider the measurement of predefined outcomes as the most valid form of research. We analyse the history of the evidence-based paradigm in the field of medicine…

Despite the growing volume of research on data use systems or data use activities in which teachers engage, micro-process studies--investigations of what teachers and others actually do under the broad banner of "data use" or "evidence-based decision making"--remain substantially underdeveloped. Starting with a review of the…

Lynn (2010) suggests that differences in average intelligence explain many of the differences observed across the Italian regions. This paper puts forward a methodological critique to his study, coupling it with an empirical test showing that Lynn's analysis is not sufficiently robust to support its conclusions. (Contains 2 tables.)

Using data from a new household survey on environmental attitudes, behaviors, and policy preferences, we find that current weather conditions affect preferences for environmental regulation. Individuals who have recently experienced extreme weather (heat waves or droughts) are more likely to support laws to protect the environment. We find…

Many measurement biases affect student evaluations of instruction (SEIs). However, two have been relatively understudied: halo effects and ceiling/floor effects. This study examined these effects in two ways. To examine the halo effect, using a videotaped lecture, we manipulated specific teacher behaviors to be "good" or "bad"…

This report presents the findings of a rigorous experimental impact evaluation and implementation study of one such intervention, the Content Literacy Continuum (CLC), developed by researchers at the University of Kansas Center for Research on Learning. This evaluation of CLC was conducted by three partnering organizations: REL Midwest, MDRC, and…

To investigate the construct validly of a section of a high stakes test, an exploratory factor analysis using principal components analysis was employed. The rotation used was varimax with the suppression level of 0.30. Eleven factors were extracted out of 35 reading comprehension items. The fact that these factors emerged speak to the construct…

Both California state law and the federal No Child Left Behind Act (NCLB) require that all schools assess the English language proficiency of newly enrolled students who speak a language other than English at home and, annually, all English learners (ELs) already enrolled. California meets this requirement by administering the California English…

School voucher and education tax credit programs have proliferated in the United States over the past 2 decades. Advocates have argued that they will enable families to become active consumers in a free and competitive education marketplace, but some fear that these programs may bring a heavy regulatory burden that could stifle market forces.…

As evidence-based practices become increasingly advocated for and used in the human services field it is important to integrate issues raised by three perspectives on evidence: empirical-analytical, phenomenological-existential, and post-structural. This article presents and discusses an evidence-based conceptual model and measurement framework…

Facing substantial financial pressure, many districts close schools in order to preserve solvency and improve student outcomes. Using a new longitudinal data set on all non-Cook County Illinois schools, we examine the determinants of high school closure decisions from 1986 through 2006. Our dataset combines information from a wide variety of…

Social scientists usually are more interested in consumers' dichotomous choice, such as purchase a product or not, adopt a technology or not, etc. However, up to date, there is nearly no model can help us solve the problem of multi-network effects comparison with a dichotomous dependent variable. Furthermore, the study of multi-network…

A new report titled "The Long-Term Impacts of Teachers" concludes that teachers whose students tend to show high gains on their test scores (called "high value-added teachers") also contribute to later student success in young adulthood, as indicated by outcomes such as college attendance and future earnings. To support this claim, it is not…
