Rosenthan's (1979) concept of fail-safe N has thus far been applied to probability levels exclusively. This note introduces a fail-safe N for effect size. (Author)

Questioned the statistical analyses of the Moleski and Tosi investigation of rational-emotive therapy versus systematic desensitization. Suggested means for lowering the error rate through a more efficient experimental design. Recommended a reanalysis of the original data. (LLL)

Argues against the indiscriminate use of the term "ethnography" and offers various criteria that have been suggested as distinguishing the ethnographic investigation. (HOD)

Describes a research project that will measure whether student achievement, blood pressure, height, and weight gain are influenced by the choice of color and/or the source of artificial light in the classroom. Four third-grade classrooms will be the treatment groups involving two colors and three different artificial light sources. (MLF)

Responds to Elliot Eisner's claim (Phi Delta Kappan, v. 65, p. 447-52) that educational research often affects educational practice subtly rather than overtly. Also argues, like Eisner, that educational research often is too indebted to social science language and too removed from practical applications. (JW)

An investigation into two forms of group reinforcement techniques in control of disruptive classroom behavior is described. Implications of results on behavior modification in the natural environment are discussed, as well as future research and educational trends. (Author/AV)

Concerns itself with the degree to which the nucleus of new leadership, the present generation of Botswana university students, feels committed towards their nations' desire for the creation of a unified, self-reliant, non-racial democracy which will provide economic and social justice for all. (Author/RK)

In the 1972 Studies summary of his dissertation, Gene Mittler provided an instructional strategy that promised to be an effective means of improving elementary education majors' attitudes toward art. Article gave a brief overview of his study and a reexamination of his research design. (Author/RK)

An evaluative study was carried out by the author to determine the effects of an art-based remediation program on the psycholinguistic abilities of twenty learning disabled children. (Author)

Multidimensional scaling configurations were obtained for the same set of 11 stimuli using data from two different judgmental tasks completed by the same group of subjects. The procedure was felt to be a way of obtaining useful information regarding environmental perception. (RH)

In three experiments, it was demonstrated that human newborn heart rate level can be reliably modified through classical conditioning procedures. Findings support the idea that early learning may occur under a variety of conditions and different theories may account for the results. (Author/SB)

This chapter examines the core analytic elements of randomized experiments for social research. Its goal is to provide a compact discussion for faculty members, graduate students, and applied researchers of the design and analysis of randomized experiments for measuring the impacts of social or educational interventions. Design issues considered…

Cover story, in the sense of context, is a potentially relevant factor in the assessment of reasoning and problem solving in science, given repeated demonstration of its effects on laboratory tasks. This study follows up on a preliminary interview study that showed cover story influenced the way students were assessed at the end of an…

This chapter describes how the mean of fractal processes does not exist and is not a meaningful measure of some data. It discusses how important it is to stay open to the possibility that sometimes analytic techniques fail to satisfy some assumptions on which the mean is based. (KHR)

Task-based language assessment (TBLA) grows from the observation that mastering the grammar and lexicon of a language is not sufficient for using a language to achieve ends in social situations. In TBLA, language use is observed in settings that are more realistic and complex than in discrete skills assessment and that typically require the…
