This volume provides alternatives for tackling existing empirical, methodological, and analytical challenges. It does so by providing a broad overview of less established, as well as emerging methods, which are of great relevance for current research on professional learning and development. As such, it offers a comprehensive collection of…

An opportunistic experiment is a type of randomized controlled trial that studies the effects of a planned intervention or policy change with minimal added disruption and cost. This guide defines opportunistic experiments and provides examples, discusses issues to consider when identifying potential opportunistic experiments, and outlines the…

As evidence-based reform becomes increasingly important in educational policy, it is becoming essential to understand how research design might contribute to reported effect sizes in experiments evaluating educational programs. The purpose of this study was to examine how methodological features such as types of publication, sample sizes, and…

The scientificalization of educational research methods was always the most predominant in the two tides of educational experiment in China in the twentieth century, the result of which was unexpectedly dissatisfactory, because researchers misunderstood the connotation of scientificalization in such a degree that resulted in the worship for…

In recent years, national policy experts have questioned the overall quality of educational research, and they have suggested that researchers strengthen their scientific methods by maximizing the use of experimental designs. To promote more rigorous methodology, we discuss several new and often-overlooked opportunities for incorporating…

Using meta-analysis, randomized experiments in education that either clearly did or clearly did not experience student attrition were examined for the baseline comparability of groups. Results from 35 studies suggested that after attrition, the observed measures of baseline comparability of groups did not differ more than would be expected given…

Explains the characteristics and importance of random assignment in experimental research on education. Considers factors supporting causal inferences, the nature of "assignment units," differences between random sampling and random assignment, the characteristics of randomization tests, forms of random assignment, and effects of experimental…

Criticizes an earlier essay that questioned the validity of contemporary educational research practices, especially those involving experimentation. Argues that research using experimentation is valid and can lead to new and generalizable knowledge. (FMW)

Experimental studies conducted since 1980 were reviewed. Each of the 34 studies concerning problem solving is briefly summarized, followed by comments, criticisms, and/or concerns. A summary indicates that experimental research of the 1980s seems to focus on: (1) children's processes, understanding, functioning, difficulties, and representations;…

Two interventions were studied in this project: a drama program presented by three visiting drama consultants in five classes and a daily story-reading period presented by the teacher in three classes and by the co-investigator in another three classes. The interventions lasted for 12 weeks. Subjects were 325 first grade pupils from 21 classrooms…

Discusses the characteristics and development of a computer simulation laboratory for educational administration research at the University of Wisconsin at Madison, and reviews an experimental study performed at the laboratory on stress in decision-making. Explores how simulations provide researchers access to experimental conditions unavailable…

Examines the psychology of learning and its application to work in the laboratory. States that the working memory capacity of students is limited; therefore the amount of information they can process needs to be controlled and "recipe following" in the laboratory is perfectly reasonable. (RT)

Experimental methods have been used extensively for many years to conduct research in education and psychology. However, applications of experiments to investigate technology and other instructional innovations in higher education settings have been relatively limited. The present paper examines ways in which experiments can be used productively…

The nine-volume Survey Kit is designed to help readers prepare and conduct surveys and become better users of survey results. All the books in the series contain instructional objectives, exercises and answers, examples of surveys in use, illustrations of survey questions, guidelines for action, checklists of "dos and don'ts," and…

This article suggests the use of structural equation modeling in special education research, to analyze multivariate data from both nonexperimental and experimental research. It combines a structural model linking latent variables and a measurement model linking observed variables with latent variables. (Author/DB)
