This article describes the analysis of regression-discontinuity designs (RDDs) using the R packages rdd, rdrobust, and rddtools. We discuss similarities and differences between these packages and provide directions on how to use them effectively. We use real data from the Carolina Abecedarian Project to show how an analysis of an RDD can be…

Suggests that, by looking for commonalities and differences across settings, tasks, working methods, goals, and values, a framework for understanding collaboration can be constructed that preserves the benefits of rich descriptive accounts of collaboration. Emphasizes the importance of multiple definitions and multiple models of collaborative…

Discusses ways in which the dialectic between differing approaches to studying, theorizing, and representing collaboration may illuminate issues related to the nature and scope of scholarly inquiry. Contains 15 references. (Author/SLD)

The heuristic value of Chilcott's essay lies less in its support for structural functionalism and more in its concern to reexamine theory in the work of earlier educational anthropologists for what earlier theories and practices can add to current research. (SLD)

A set of concerns related to home education that is infrequently studied, namely, the content and direction of research in education, is examined. Issues surrounding home education have not been given adequate attention. A sample of home education researchers was gathered by compiling a list of authors who had published in the "Home School…

This book uses concepts familiar to those with a working knowledge of basic statistics and classical test theory to present item response theory models that are currently in wide use in both practical testing and research. The book would serve as a good entry-level graduate text in psychometrics and measurement methods. (SLD)

To the debate between the Rortyan pragmatic model of scientific research advocated by Cleo Cherryholmes and the scientific realism espoused by Ernest R. House is added another model for educational research based on the realism of John Dewey's pragmatism. Constructivist and behaviorist aspects of Dewey's philosophy are explored. (SLD)

The Jansen and Roskam (1986) approach to joining categories of graded responses presents valid arguments that are subject to empirical test. The multiplicative Poisson (MPM) model of D. Andrich can be seen as an approximation to the continuous response model of Muller (1987). An extension of the MPM is suggested. (SLD)

These further remarks on the nondichotomization of graded responses attempt to clarify the differences in perspective between the two previous articles. The special case of the multiplicative Poisson model reveals why the joining assumption and dichotomization are not, in general, properties of the unidimensional Rasch model. (SLD)

Discusses methodology to examine the problem of spatial mismatch of jobs, showing how the simple accessibility measures used by Daniel Immergluck (1998) are poor reflections of the availability of jobs to an individual and explaining why a gravity model is a favorable alternative. Also discusses the unsuitability of aggregate data for testing the…

Discusses the methodology used to analyze the availability of jobs for residents of a particular neighborhood, examining the spatial mismatch hypothesis in the context of jobs available to young minority males in cities. Considers the use of gravity models and the importance of large-scale data sets. (SLD)

D. F. Halpern and her colleagues criticize overly narrow scholarship and examine the economics of scholarship and the criteria for evaluation. Psychology needs a historically grounded, open-minded, and theoretically sophisticated view of scholarship that emphasizes the responsibilities of educational institutions in meeting the needs of society.…

Reflects on "Scholarship in Psychology" from the perspective of liberal arts college professors. Applauds features of the report's multidimensional understanding of scholarship, suggests clarifications and criticisms, and outlines ways to define faculty priorities and rewards. (SLD)

The Task Force on Defining Scholarship in Psychology has called for an increased emphasis on the scholarship involved in teaching for faculty evaluation processes. Each college and university should also examine its own institutional goals and interests and translate these into their own faculty-evaluation processes. (SLD)

Reviews Barbara J. King's detailed observations of free-ranging baboons in Amboseli, Kenya; these observations contain a mass of recent research and report studies of divergent theories in primatology and paleontology. King's studies supply direct evidence about primate behavior that conveys information and show how natural information transfer is…
