The problem of change scores' correlation with initial status and the problem of low reliability in the measurement of change are addressed. By treating the correlation between initial status and change as a design problem rather than a statistical issue, research questions can be formulated in terms of changes in the shapes of growth curves…

Fred N. Kerlinger has been hailed as having contributed to the transformation of the way that behavioral scientists and educators read research reports, design and execute research, and draw conclusions about research. In 1960 he introduced the notion that educational research is fraught with mythology. Three of the research myths that he…

Although it makes a great deal of sense to attempt to design reading research so as to be able to generalize beyond the particular reading passages used in an experiment, the suggestion that tests of statistical significance are a necessary part of making valid generalizations is nonsense. (HOD)

Model identification of time-series data is essential to valid statistical tests of intervention effects. Model identification is, at best, inexact in the social and behavioral sciences where one is often confronted with small numbers of observations. These problems are discussed, and the results of independent identifications of 130 social and…

This article is the first of 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 decision makers can use with confidence to identify current practices that merit continuation and to create or…

An aim of many students of human development is to penetrate behavioral variability in such a way as to reveal stable phenomena. This broad aim is challenged on numerous fronts when researchers study infant behavior, for students of infants are everywhere confronted with variability. But, in the context of research, variability of subjects'…

This article describes the use of a schematic model for developing and distributing online surveys. Two empirical studies that developed and implemented online surveys to collect data to measure satisfaction in various aspects of human resource development and adult education exemplify the use of the model to conduct online survey research. The…

A number of issues involved in the large-scale assessment of science and mathematics education were illustrated during the conduct of two national surveys: the 1977 National Survey of Science, Mathematics, and Social Studies Education and the 1985 National Survey, Science and Mathematics Education. Development of the survey questionnaires started…
