The objective of this paper is to review the outputs of selected computer programs often used to carry out a "discriminant analysis" with respect to two purposes of such an analysis, discrimination and classification. The programs selected are three BMD programs. (Author/JKS)

Two approaches to regression-based reading-level-match research designs, one of which used matched Rasch-scaled "w" scores, were tested with 544 primary grade children of different reading levels. Results call into question the conclusion that orthographic skills are compensatory for reading-disabled children. (SLD)

Reviews current computer-assisted scoring (CAS) systems and reviews the current practice of validating CAS-system generated scores. Also presents a conceptual framework and general recommendations for designing validation studies for CAS procedures. (SLD)

Presents fourth editorial in series, this one describing research design and explaining its relationship to statistical design. Research design, validity, and research approaches are examined, quantitative research designs and hypothesis testing are described, and control and statistical designs are discussed. Concludes with section on the art of…

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…

Compared the power of analysis of covariance (ANCOVA) and two types of randomized block designs as a function of the correlation between the concomitant variable and the outcome measure, the number of groups, the number of participants, and nominal power. Discusses advantages of ANCOVA. (Author/SLD)

Contrasts ideas of culture in social constructionist and cultural study research designs, addressing how each type of design impacts issues that can be analyzed in research studies. Explores implications for objectivity and validity in speculative cultural study research. Suggests how technical writing can be constituted as an object of study…

Describes the design, implementation, and release of the 1999 National Household Education Survey (NHES). Includes discussion of the goals of the survey, selection of survey topics, and design of the survey instruments. (Author)

This article addresses the characterization and circumvention of E. H. Simpson's paradox in designs involving two ordered variables and illustrates the recommended procedure using a two-sample application involving estimation of correlation and a single-subject application involving the estimation of lag(1) autocorrelation.

Purpose. Even though consumer-directed care models are being advocated for use among elder populations, there are few data on the extent of elder interest in participating in the management of community long-term-care services, who they want involved in making these decisions, or their perceptions regarding the relative importance of different…

This article considers the emerging method of design experimentation, and its developing use in educational research. It considers the extent to which design experiments are different from other, more established, methods and the extent to which elements of established methods can be adapted for use in conjunction with them. One major issue to be…

In the past quarter century, research on adolescence has expanded from a near exclusive focus on intraindividual processes to a concern with individuals in an interpersonal context. Today, studies of the impact of relationships within families, with peers, and with romantic partners account for a large proportion of research in the field. This…

The purpose of this study was to investigate the response of kindergarten students at-risk for reading failure to a two-tiered vocabulary intervention delivered in the context of a shared storybook reading activity employing rich and robust vocabulary instruction. Rich vocabulary instruction is defined as explicit vocabulary instruction in which…

This handbook is a much expanded version of the original Learning Activities Survey published by Dr. Kathleen P. King of Fordham University in 1998. Based on her ground breaking research in this field where she used a mixed methodology research approach to study transformative learning, the book will provide a model of research, firsthand…

A 2 x 2 experiment was conducted in which instructor nonverbal immediacy and verbal immediacy were manipulated in a college classroom to examine causal links with cognitive and affective learning outcomes. Previous criticisms concerning immediacy and learning research were considered and multiple operationalizations of cognitive learning (i.e.,…
