This paper is meant to highlight the occurrence of Simpson's Paradox when using aggregated data obtained from two IEA studies in Israel, while ignoring the effect of a powerful intervening variable in the local context--the ethnicity factor. It will demonstrate faulty conclusions regarding either the absence of relationships between a contextual…

In this paper we discuss several key challenges encountered when conducting a study of the continuity of participation in the child care subsidy program. While many of these issues are familiar to those who have studied participation dynamics in other assistance programs, and to those familiar with survival analysis, we describe these challenges…

Standardized tests have been selected as a key assessment factor in expanding the academic achievement of the national student population. However, these tests position immigrant students at the risk of academic failure, leading education experts to search for new strategies and teaching models. The "Handbook of Research on Assessment…

Since Topping published his literature review on peer assessment in 1998, the number of studies on this subject has doubled, if not tripled. However, along with this expansion, the diversity of peer assessment applications increased equally fast. Based on recent literature, this contribution focuses specifically on the diversity that has come to…

Written in a refreshing conversational style, this text thoroughly prepares students, program administrators, and new evaluators to conduct evaluations or to use them in their work. The book's question-driven focus and clear discussions about the importance of fostering evaluation use by building collaborative relationships with stakeholders set…

The vital role of principalship in improving schools in general and enhancing student achievement in particular has been well documented. Given its importance, there is a need for tools to improve principalship, particularly ones emphasizing those dimensions associated with student achievement. Given the accountability movement, with its…

The Fifth Edition of the :Handbook of Research on Teaching" is an essential resource for students and scholars dedicated to the study of teaching and learning. The volume covers a vast array of topics ranging from the history of teaching to technological and literacy issues. In each authoritative chapter, the authors summarize the state of…

The nation is showing an unprecedented focus on increasing the rigor in education and preparing students for college. The college readiness trend is driving changes in the ways in which the nation uses student test data. Educational data are no longer limited to static data snapshots showing the status of a student performance at one point in…

Eight different variable selection techniques for model-based and non-model-based clustering are evaluated across a wide range of cluster structures. It is shown that several methods have difficulties when non-informative variables (i.e., random noise) are included in the model. Furthermore, the distribution of the random noise greatly impacts the…

In a recent paper, Hessen ("Psychometrika" 70(3):497-516, 2005) introduces the class of constant latent odds-ratios models as an extension of the Rasch model for which the sum score is still the sufficient statistic for ability. In this paper the relation between both the general and the general parametric constant latent odds-ratios model and the…

The classification by many scholars of numerical research processes as quantitative and other research techniques as qualitative has prompted the construction of a third category, that of "mixed methods", to describe studies that use elements from both processes. Such labels might be helpful in structuring our understanding of phenomena. But they…

This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

This annotated bibliography surveys key resources and research related specifically to language learning and literacy. It focuses on resources that will be valuable to teaching professionals and researchers who specialize in the areas of foreign and second language teaching, language arts and first and second language literacy. Significant…

The authors investigated the association between adaptive and maladaptive perfectionism and relationship quality in 197 engaged couples. When both partners were maladaptive perfectionists, they were more likely to be grouped into less functional couple types. Couples in which both partners were adaptive perfectionists tended to cluster in more…
