Investigated the effect of prior knowledge and strategy training on monitoring accuracy among college students, comparing debilitative, no-impact, and facilitative hypotheses. Overall, knowledge acquired through brief strategy training improved performance, confidence, and monitoring accuracy independent of general ability and general mathematics…

Compared the effect of problem solving-based computer- assisted instruction (PSCAI) and lecture-Internet-discussion instruction (LIDI) on Taiwanese high school students' science achievement and attitudes. Pretest-posttest investigation indicated that PSCAI students scored higher, but not significantly higher, than LIDI students. There were…

Used hierarchical linear models to estimate the extent to which five inquiry-based teacher practices promoted student achievement and reduced achievement gaps among diverse students. Data from the National Education Longitudinal Study suggest that teacher practices that improve overall academic excellence simultaneously are as likely to contribute…

Examined the effects of positive interdependence versus no interdependence on college students' academic achievement. Students took weekly electronic quizzes where they could interact with groupmates in a chat room. Achievement was measured via biweekly examinations. Students in the positive interdependence condition engaged in significantly more…

Evaluated the Connected Mathematics Project (CMP), a middle school reform mathematics curriculum used in Louisiana's Lafayette parish. Analysis of Iowa Test of Basic Skills and Louisiana Education Assessment Program mathematics data indicated that CMP schools significantly outperformed non-CMP schools. Surveys of teachers and students showed that…

Developed a heuristic strategy (SOLVED) to explain the processes involved in understanding and solving mathematical word problems (problem translation, problem interpretation, solution planning, solution execution, and solution monitoring) among upper elementary students. Results indicated that SOLVED was more effective in aiding both short-term…

The concept of a behavior domain is a reasonable and essential foundation for psychometric work based on true score theory, the linear model of common factor analysis, and the nonlinear models of item response theory. Investigators applying these models to test data generally treat the true scores or factors or traits as abstractive psychological…

This article extends recent research on item parameter drift by investigating the robustness properties of basic unidimensional IRT models. Specifically, the article explores whether it is possible to advocate the consistent choice of one model over another based on its robustness properties under drift. On the one hand, it is shown that the…

Described in this paper are the first three activities of a research program designed to assess the differential validity and utility of successive and simultaneous approaches to the development of equivalent achievement tests in the French and English languages. Two teams of multilingual/multicultural French-English teachers used the simultaneous…

This article applies the Breslow-Day test of trend in odds ratio heterogeneity (BD) to the detection of nonuniform DIF. A simulation study was conducted to assess the power and Type I error rate of BD, as well as a combined decision rule (CDR), whereby a decision of the existence of DIF was based on a combination of the decisions made using BD and…

It is an established matter that the total information in multivariate data is defined as the sum of eigenvalues of the variance-covariance matrix. In this article, we challenge this time-honored tradition and look at another definition of the total information in data from a dual scaling perspective. This proposal is a step toward unifying the…

The purpose of this study was to examine the potential effect of false assumptions regarding the motivation of examinees on item calibration and test construction. A simulation study was conducted using data generated by means of several models of examinee item response behaviors (the three-parameter logistic model alone and in combination with…

In this article the authors demonstrate two instances where the jackknife can be used to enhance hierarchical linear model (HLM) analyses. The jackknife was used to improve the HLM estimates of composite measures by jackknifing over items. The first study examined fixed-effects and variance component estimation. The jackknife appeared to reduce…

This article examines principals' espoused values and their values in action. It provides a reanalysis of previously collected data through a values lens. The original research study was an international quantitative and qualitative investigation of principals' leadership approaches that was based in 15 schools. This particular excerpt of the…

The purpose of this study was to examine the learning outcomes of students who had recently completed a two-year community-based Native Teacher Education Program (NTEP). The participants were 22 graduates of an NTEP who responded to open-ended items in a questionnaire on what they had learned throughout the program. Four women also participated in…
