This study investigated trends in the number and types of research articles published in selected special education journals in 1968, 1977, and 1986. Approximately half of the articles were not data based. Qualitative research accounted for about 6 percent of the research. Relatively stable rates of quantitative and qualitative research were found…

A review of 158 applied behavior analysis studies with children as subjects, published in the "Journal of Applied Behavior Analysis" between 1980 and 1990, found that (1) 16% measured the accuracy of independent variable implementation, and (2) two-thirds did not operationally define components of the independent variable. Specific recommendations…

Explains the statistical technique of survival analysis which is suggested as appropriate for evaluation of longitudinal speech and language data. In survival analysis, probabilities are calculated not just for groups but also for individuals in a group, a major advantage for clinical studies. Both nonparametric and semiparametric survival…

Discussion of the relationship between child maltreatment and child disability identifies three categories: (1) maltreatment causes many disabilities; (2) children with disabilities are more vulnerable to maltreatment; and (3) other primary causal factors increase risk for both violence and disability. Maltreatment is also seen as impeding student…

This study presents detailed distributional analyses of voice onset times (VOTs) from seven 5-year-old children and 14 adults. Distributional non-normality was common in both data sets with children showing greater skew. Results suggest that theories of VOT development should not be based solely on means and standard deviations but need to address…

The purpose of this article is to critically examine some stated discrepancies between qualitative and quantitative research by taking actual studies as a starting point. It is argued that in ordinary empirical research within psychology and education, both approaches should be considered based on critical realism, and that the ordinary validity…

Combining psycholinguistic technologies and systems analysis created advances in motivational profiling and numerous new behavioral engineering applications. These advances leapfrog many mainstream statistical research methods, producing superior research results via cause-effect language mechanisms. Entire industries explore motives ranging from…

Selecting a statistical framework for a behavioral study has profoundly different results than does a linguistically framed research strategy. The linguistic strategy overcomes many limitations inherent in statistical strategies and offers more meaningful results. Inferential statistical studies often discuss how the findings "explain" the results…

In this article the authors discuss issues faced by early career researchers, including the dichotomy, which many research textbooks and journal articles create and perpetuate between qualitative and quantitative research methodology despite considerable literature to support the use of mixed methods. The authors review current research literature…

This paper assesses the value of research, not on its methodology type but on its goal and accomplishments. It outlines an idea for developing a knowledge base capable of informing teacher education program planning and other educational policy decisions. Studies are described that advance knowledge about causal relationships between classroom…

Qualitative and quantitative social science research methods rather than representing opposing research methods instead are reinforcing research traditions. The ability of either research methodology to make lasting and important contributions requires the ability to synthesize and integrate with the other approach. While the assumptions of each…

Band, orchestra, and choir festival evaluations are a regular part of many secondary school music programs, and most such festivals engage adjudicators who rate each group's performance. Because music ensemble performance is complex and multi-dimensional, it does not lend itself readily to precise measurement; generally, musical performances are…

The original nine programs for semantic differential analysis have been condensed into three programs which have been further refined and augmented. They yield: (1) means, standard deviations, and standard errors for each subscale on each concept; (2) Evaluation, Potency, and Activity (EPA) means, standard deviations, and standard errors; (3)…

In previous research, no relationship was found between test factor structure and test hierarchical structure. This study found some correspondence between test factor structure and test inter-item dependency structure, as measured by a log-linear model. There was an inconsistency, however, which warrants further study: more significant two-item…

Both common factor analysis and components analysis are useful techniques for reducing the number of variables in a data set or for identifying underlying covariance structures that exist among a set of variables. Although researchers have for some years debated the appropriateness of selecting one of these methods over the other, components…
