This article describes the strengths and weaknesses of different models of classification (primarily monothetic and polythetic) and then focuses on cluster analysis as a method of pursuing a polythetic model. Design features that need to be incorporated in a cluster analytic study are discussed in relation to theory formulation, internal validity,…

This article is the third contribution to a research methods series dedicated to getting good results from survey research. In this series, "good results" is a stenographic term used to define surveys that yield accurate and meaningful information that decision makers can use with confidence when conducting program evaluation and policy assessment…

Mixed methods research has increased in popularity over the past 20 years. Literature reveals that exploratory qualitative analysis followed by confirmatory survey research is common and concurrent studies outnumber longitudinal design. Longitudinal studies using quantitative and qualitative methods in sequence for exploratory purposes are rare,…

Short-term studies often do not capture the full story of the effect that a researcher is trying to describe. If one wishes to elucidate long-term educational processes and outcomes, the only direct way of doing so is to stretch the duration of research projects and to study the same subjects over time. The limited availability of valid…

This manual discusses cost effectiveness in evaluating training modalities in population education for Asian and Pacific nations. Chapter 1 defines training modalities and offers 10 models that are in use in this geographic region. Chapters 2 and 5 discuss evaluation, cost effectiveness versus cost benefit analyses, estimating and analyzing costs,…

Children ages 1 1/2 to 3 years were tested to determine their comprehension of the terms "in,""on," and "under." It was found that children who listened to a pretest story involving the objects to be used in the study showed markedly better comprehension of the terms than children not exposed to the pretest activity.…

Delineates various levels of theory with implications for research in library and information science. Based upon a review of literature on theory building and research methods in the social sciences, a model is proposed which displays a taxonomy of theory in hierarchical form. (EM)

Although the primary responsibility rests with the authors of articles reporting nonsignificant results to demonstrate the worth of the results by discussing the power of the tests, consumers should be prepared to conduct their own power analyses. This article demonstrates the use of power analysis for the interpretation of nonsignificant…

Discussion of conceptual and methodological aspects of reading intervention research focuses on nine specific design limitations of previous intervention research; ways to measure and analyze change as a function of development, treatment intervention and ecological influences; assumptions of individual growth models; and advantages, conditions,…

Addresses issues concerned with the investigation of creativity across various human cultures, including data collection from a limited cultural base, a three-level approach to cross-cultural studies of creativity, identification of basic cultural paradigms characteristic of a specific culture, and barriers to mature cross-cultural relativism.

Because of the importance of single-subject studies in mental retardation research, a meta-analysis of the literature examining interrater agreement for visual analysis of single-subject data was conducted. Analysis revealed an overall itinerant agreement value of 0.58 for 14 studies representing 789 raters. Effects of data type, design type,…

This study examined the representativeness of a time-sampling observational procedure to evaluate students with behavior disorders by examining error in samples of varying size in comparison to a criterion measure. Analyses of both single subject and multiple subject designs suggested that samples of 16 to 20 observational sessions of eight-minute…

Examination of methodological issues in the design and interpretation of studies on the genetics of reading disability suggests three tests of increasing rigor for determining whether reading score distributions are categorical and thus not subject to analyses which assume a continuous normal distribution. Also noted are interactive relationships…

Ethnography derives from traditional anthropology, where time in the field is needed to discern both the depth and complexity of social structures and relations. Funding bodies, seeking quick completion, might see ethnographies as unlikely to satisfy 'value for money' criteria, in spite of the rewards to be gained from time-consuming 'thick…

The purpose of this study was to assess the effectiveness of a Social Story [TM] intervention in teaching a young child with hyperlexia to appropriately obtain the attention of his peers. The Social Story intervention consisted of verbal and visual cues incorporated into an age-appropriate storybook format. Attempting to obtain the attention of a…
