Three studies examined the hypotheses that: (1) codability and not extent of distance determines difficulty; (2) critical features and not whole objects are coded; and (3) implicit perceptual axes provide a frame of reference for coding the display. Results supporting these hypotheses are discussed in terms of a description of spatial…

This paper explores the nature of the contribution that can be made to administrative theory by recent developments in the philosophy of science and the emerging new views of science: notably, the arguments of Richard Bates and Thomas Greenfield. These emerging views of science can sustain a science of administration that escapes their major…

Describes a study that determined which reference sources, including nongovernment, were most useful in answering questions about U.S. congressional matters by using a computer science technique called state-transition modeling. Implications for document librarians, the Government Printing Office, and the Superintendent of Documents are discussed.…

Explains exploratory sequential data analysis (ESDA) and outlines ESDA characteristics that could help human-computer interaction investigators using sequential data make better conceptual and methodological choices. Behavioral, cognitive, and social factors are considered, and failures of expertise, time management, and databased problems are…

This article compares three models that have been the foundation for approaches to the analysis of statistical significance in early childhood research--the Fisherian and the Neyman-Pearson models (both considered "classical" approaches), and the Bayesian model. The article concludes that all three models have a place in the analysis of research…

Alternative tests are presented for the between-by-within interaction null hypothesis and for two within-subjects main effects null hypothesis in a split plot design. Estimated Type I error rates for the interaction tests and for several tests of the second null hypothesis are reported. (SLD)

Examines a model for children's strategies for inclusion tasks. Suggests that young children are not consistent in task strategies and that they display mixed response strategies. Strategies may change with development. (ET)

Explores the ongoing debate over quantitative versus qualitative research, arguing that qualitative research has evolved from a methodological approach into a social and political ideology. The current emphasis on narrative ways of sharing knowledge raises concerns about evaluation and hypothesis testing. (SLD)

Explains how indexers choose keywords and how results can differ between indexers by focusing on certain properties of the terms rather than on the terms themselves. Based on research in semiotics, cognitive science, discourse analysis, and reading theories. Indexing terms from 833 bibliographic records from an environmental database are analyzed.…

Examines the effectiveness of quantitative and qualitative evidence in impacting initial attitude change and the persistence of that change. Finds that both types of evidence are equally effective in changing attitudes but that the attitude change elicited by qualitative evidence tends to be significantly more persistent over time and that recall…

Combining information to estimate standardized partial regression coefficients in a linear model is discussed. A combined estimate obtained from the pooled correlation matrix is proposed, and its large sample distribution is obtained. The method is generalized to handle a random effects model in which correlation parameters vary across studies.…

This article explains and illustrates the estimation of the power of statistical tests used to analyze data in early childhood special education research, and discusses advantages and disadvantages of various ways to increase power, such as using a directional alternate hypothesis or using a parametric, rather than nonparametric, statistical test.…

Describes a study designed to evaluate the performance of an experimental semiautomatic map cataloging advisor, Mapper, in the descriptive cataloging of single-sheet maps from U.S. publishers. Hypotheses tested are discussed, treatment of experimental and control groups is described, and it is reported that Mapper helped produce better cataloging…

The hypothesis that attentional demands of word recognition covary with other measures of reading efficiency was tested with 27 undergraduates performing naming and probe-detection tasks singly and in combination. Findings support the assumption that attentional demands of basic reading are a source of differences in reading skill. (SLD)

This third in a series of articles on the effectiveness of educational technologies in higher education institutions focuses on a study of universities in Ohio that investigated faculty perceptions of the quality and importance of educational technology services. Results indicate faculty viewed quality to be inferior to importance. (39 references)…
