The existence, preponderance, and stability of misconceptions related to evolution continue as foci of research in science education. In their 2006 study, Geraedts and Boersma question the existence of stable Lamarckian misconceptions in students, challenging the utility of Conceptual Change theory in addressing any such misconceptions. To support…

Much of educational administration research suffers from lack of conformity between data analysis and research design, inattention to the test/retest stability of measurement instruments, and the use of statistics for nominal or interval data with ordinal data, random-sample statistics with nonrandom samples, and unnecessarily complex statistical…

Views intercoder reliability as a sampling problem for content analyses. Develops a formula for generating sample sizes needed to have valid reliability estimates. Suggests steps for reporting reliability. (TB)

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…

Educational researchers have claimed that the quantitative and qualitative approaches to educational inquiry are, indeed, compatible. However, it would be unfortunate to discontinue this debate. The quantitative-qualitative debate began with the interpretive approach to social inquiry. Dilthey argued that since cultural/moral sciences differ from…

Problems in current special education categorical research practices are discussed in terms of consistency and reliability, student heterogeneity, and lack of distinct categorical groups. Suggested changes include characteristic-oriented categorization, corresponding changes in dissemination of research findings, and greater specificity and…

The major finding of the Law-Related Education Evaluation Project report for Year 1 (1981), that law-related education courses can reduce juvenile delinquency, is of limited use to educational decision makers and could be misleading. The research design leaves much to be desired; however, that fact must be considered in light of the difficulty of…

This paper offers reasons for using traditional quantitative research methods and illustrates some of the considerations demanding rigor in a study on gender discrimination in school-administrator salaries. Traditional quantitative methods provide a meaningful language based on numbers and objectivity, and they are less time-consuming and complex…

Social studies research has told us very little in the past 30 years. There are several reasons for this state of affairs in social studies. First, inferential statistics has become much too prominent in research thinking and practice. Replication should be used by researchers to build a useful body of knowledge. A second reason for lack of…

This paper evaluates the logic underlying various criticisms of statistical significance testing and makes specific recommendations for scientific and editorial practice that might better increase the knowledge base. Reliance on the traditional hypothesis testing model has led to a major bias against nonsignificant results and to misinterpretation…
