A method is suggested to incorporate instruction in the concept and the application of power considerations into an applied statistics course. This is based on designing one table usable for a wide range of the type of statistical tests usually introduced in such a course. (Author)

On the premise that the more formal algebraic presentation of statistics must be placed in a concrete context to facilitate student understanding, the author presents a pedagogical device involving the construction of miniature numerical examples that illustrate how the statistical model imposes structure on empirical data.

Multiple linear regression is a versatile model for encompassing analysis of variance, analysis of covariance, and aptitude-by-treatment interaction designs. The questions of how to teach the coding of levels of a qualitative variable is addressed in this paper. (Author/LMO)

Four sections of introductory psychology were involved in a study of aptitude-treatment interactions. Two sections were taught with a high-structure curriculum, and two with a low-structure curriculum. Students' preference for structure was measured with the Inventory of Beliefs (IOB). During eight weeks of instruction, observers recorded…

A teaching aid appropriate for a beginning course on experimental design is presented. The aid is a numerical example which illustrates some of the theoretical interrelations among three competing design analysis strategies for estimating treatment effects in random assignment designs. The analysis strategies considered are analysis of variance…

The purposes of this study were to investigate the effects of occupational information classes on the vocational interest patterns of slow learning senior high school boys, and to develop and utilize an occupational information curriculum appropriate to the intellectual level of the students involved. From a random sample of 80 slow learning 11th…

The educational priorities of 90 key decisionmakers -- school administrators, teachers, and community members -- from school districts representing three economic levels, were investigated to determine: (1) the types of educational objectives preferred by each group, (2) the agreements within and among the three groups of decisionmakers in these…

The personal characteristics of teachers and the situational characteristics of work settings were identified and studied in relation to adoption and implementation of innovations among teachers. One hundred teachers were administered a questionnaire to identify teacher and situational characteristics. A subsequent interview determined the…

Presents the results of an experiment that evaluated the efficiency of analogy in the conceptual restructuring of a science topic. The experiment involved a fifth-grade class studying water and heat flow. Discovered that analogy can act as an effective trigger for restructuring knowledge. (MJP)

SINCE NO TESTS OF SPANISH SPEAKING ABILITY AT THE ELEMENTARY LEVEL WERE AVAILABLE WHEN THE PROJECT BEGAN (1960), IT DEVISED THREE CAREFULLY CONSTRUCTED ITEMS TESTING THE SEPARATE ASPECTS OF THE SPEAKING SKILL--PHONETIC ACCURACY, STRUCTURE, AND EASE AND NATURALNESS OF EXPRESSION. A RANDOM SELECTION OF FIFTH-GRADE PUPILS WERE TESTED INDIVIDUALLY,…

One hundred and thirteen students of general speech were assigned to an experimental group (54) and a control group (59), of which only the former could view themselves on a video tape-recorder. The hypothesis was that students would more easily evolve an actual self closer to their ideal self, would evolve a self-awareness which is more similar…

A summary and comparison of the statistical analysis and results of the first three GUME research projects investigating foreign language teaching methods are presented in this report. The methods investigated are the habit-formation or implicit theory and the cognitive-code learning or explicit theory with either source-language or…

The evaluation report is one of seven produced for the Occupational Exploration Program (OEP), a series of simulated occupational experiences designed for junior high school students. Describing the pilot testing of the simulation dealing with education, the report contains sections describing the simulation context, evaluation procedures,…
