Critically examining common statistical approaches and their strengths and weaknesses is an important step in advancing recreation and leisure sciences. To continue this critical examination and to inform methodological decision making, this study compared three approaches to determine how alternative approaches may result in contradictory…

The interpretation of subtest profiles from intelligence testing remains popular among many practitioners who use subtest performance to draw diagnostic conclusions, in spite of criticism by some researchers, who point to the low reliability and predictive validity of subtest scores in predicting achievement outcomes. Prior research outlines two…

The authors contend that most research in education lacks statistical power. They feel that the poor use of statistics as a tool for enhancing internal validity must be remediated. The adoption of a new convention is proposed in order to put statistical certainty into reasonable perspective. (RLV)

The Cooperative Institutional Research Program (CIRP) of the American Council on Education is an example of a systematic program of social and educational research in which survey methods using questionnaires constitute a major technique for collecting data. This longitudinal research program is dedicated to the study of higher education,…

The generation of empirically-based equations is within the grasp of most researchers in occupational education. This paper was designed to develop a sensitivity to the need for cross-validation in these circumstances. Program CROSVAL is a means of bridging the gap between the need for, and mechanization of, cross validation. (Author/DS)

Where do those in schools start sorting the wheat from the chaff, genuine growth potions offering long-term improvement from the elixirs, short-term opportunism and/or unrealistic expectations? The current and growing emphasis on evidence informed policy and practice is as good a place as any. The purpose of this article is to take up the issues…

This memorandum reports results of an analysis designed to obtain answers to the following questions: (1) How does the Overall High School Average compare with Converted Rank in Class as a predictor of Freshman Year Grades in college? and (2) Will more detailed information provided by analysis of high school records by subject help to improve…

The impact of open education on today's curriculum has been extensive. Of the many requests for research in this area, none is more important than instrument validation. This study examines the internal structure of Barth's Assumptions about Learning and Knowledge scale and explores its relationship to established "progressivism" and…

Results are described for the first two phases of a study to develop and evaluate models of student progress in a technical training course being offered in a computer managed instructional environment at Lowry Air Force Base, Colorado. Several categories of models were developed in Phase I and defined by model type and by the type of variables…

The study of teacher effectiveness is confronted by a number of problems that are generally associated with the conduct of behavioral research. It is possible in some instances to resolve or circumvent some of the current methodological stumbling blocks that tend to reduce the credibility of research findings. This paper discusses three…
