A reanalysis of research reported in the "Journal of Industrial Teacher Education" demonstrates a tendency among researchers to base interpretations of data entirely on the results of tests for statistically significant differences. The appraisal suggests that several of the published findings should be reviewed using additional data…

Few educators pay attention to educational research results because the research is removed from the realities of the classroom, relies almost exclusively on tests of statistical significance, and is usually the result of the publication requirements of universities. Cites 10 more reasons for poor research and advises typical research pitfalls to…

Review of research investigating gender differences in computer-related behavior examines statistical and methodological flaws. Issues addressed include sample selection, sample size, scale development, scale quality, the use of univariate and multivariate analyses, regressional analysis, construct definition, construct testing, and the…

This article has three purposes: to explain the two different uses of power analysis that can be used in health education research; to examine the extent to which power analysis is being used in published health education research; and to explain the implications of not using power analysis in research studies. Articles in seven leading health…

This review critiques the use of Lev Vygotsky's concept of the zone of proximal development (ZPD) in quantitative research that focuses on the role communication plays in learning. A study that makes claims in terms of the ZPD should include a pretest, a problem-solving activity, and a posttest. Without these minimal elements, researchers are not…

The methodology of five national surveys designed to estimate the scale and scope of training was analyzed to identify the reasons underlying the variability and unreliability of estimates of education and training. The five surveys were as follows: May Triennial Adult Education Supplement to the Current Population Survey, National Longitudinal…

Third in a series, the monograph summarizes the key evaluation issues, design approaches, and statistical techniques used in conducting the 1980-1983 impact evaluation of Indian Education Act Title IV Part A programs. The monograph describes the major problems in evaluating the program to determine the degree of its positive contribution to…

Since about 1962, researchers have explored the effectiveness of educational software in the schools under various conditions, and many have concluded that computer assisted instruction (CAI) is effective. Many of the studies reviewed to support this conclusion, however, had design flaws. Reviews of educational software effectiveness studies have…

This study guide provides an overview and model of business research. First, introductory material defines research and discusses the benefits of studying business research methods for both producers and consumers of research. In the next section different types of research are discussed, including experimental, ex post facto, quasi-experimental,…

In this revised version of ED 127 248, the author has re-evaluated response data from a survey of 1680 selected engineering freshmen at 42 schools. The survey was an effort to identify distinguishing characteristics of the increasing numbers of women entering engineering programs. Respondents, who included men and women, were asked to give…

Since problems associated with the statistical methodology of educational research are becoming increasingly important, this paper examines a subset of problems associated with the analysis and interpretation of aggregated data. Two major questions arise: (1) if a researcher knows the level (e.g., individual, teacher/classroom, school, school…

The present paper contributes to research methodology as practiced in the field by providing practitioners with a concise statement of the problems in analyzing unbalanced designs, and by clarifying the conditions under which the analysis alternatives are most appropriate. The purposes of the present paper are: (1) to examine the analysis…

In an effort to identify distinguishing characteristics of the increasing numbers of women entering engineering programs, a survey was made of 1,680 selected engineering freshmen at 42 schools. The 230-question survey required male and female students to respond to multiple-choice items covering their family and educational background, study…

A proposal to monitor and summarize the experience that will be gained during the course of the ATS-F Education Satellite Communications Demonstration is described. The goals of the demonstration and the context in which it must be evaluated are discussed in an introduction. Subsequent sections deal with specific analytic approaches proposed, the…

The problem of the comparability of change scores is investigated. Change quotients and residual change scores are evaluated as alternative approaches and methods for estimating the true change and true score residual, the reliability of change scores and residuals, and procedures for constructing confidence intervals for residuals are explored.…
