Three techniques for assessing the adequacy of correlation matrices for factor analysis were applied to four examples from the literature. The methods compared were: (1) inspection of the off diagonal elements of the anti-image covariance matrix S(to the 2nd) R(to the -1) and S(to the 2nd); (2) the Measure of Sampling Adequacy (M.S.A.), and (3)…

Multiple matrix sampling (MMS) procedures were utilized to determine the necessary parameters of a Pearson Type I curve. Empirical norms distributions were approximated by both the Type I model and the negative hypergeometric model. Four existing ITED norms distributions, two subtests and two grades, were approximated by the MMS procedures. Two…

Attribution theory predicts that actions seen as specifically directed toward a person have greater impact than those not so directed. It was hypothesized that agreement between self-evaluation and another's evaluation increases personalism of received evaluations, increasing both impact and tendency to reciprocate liking or disliking. In a 2 x 2…

The purpose of this study was to construct-validate the REPI. The judgmental data of 25 content specialists were examined. The response data of 416 students were item analyzed and submitted to principal components analyses with orthogonal and oblique rotations. The items were generally representative of the content universe and 50 items optimally…

The assessment and diagnostic procedures of a comprehensive accountability plan were applied to several elementary schools from a large midwestern state. Pretest and posttest Word Knowledge and Reading scores from the Primary II Metropolitan Achievement Test administered in 1970-71 to third-graders were used. These data were used to compute…

The purpose of this research was to assess the criterion-referenced validity of student ratings of instructors. A total of 480 undergraduates rated their instructors using a special rating scale designed to parallel the Flanders Interaction Analysis Categories. Expert observers also rated the instructors using the standard form of the Flanders…

A random 5% sample of those 6,341 day college students who were enrolled in the fall of 1972-73 but not in the spring of 1972-73 were telephoned to gather followup information. Of the 316 students in the sample, 91 were contacted and provided the following information: (1) most were not currently enrolled in college anywhere; those who were…

The purpose of this study was to identify the factors in attrition over which Southwestern College might exercise some control and through which experimentation could be conducted toward changing the patterns of attrition. Data were gathered from college files on every student who withdrew from one or more classes for the fall 1971 semester. A…

Investigation of publicly supported kindergartens in Saskatchewan, Canada is reported. The Minister's Committee on Kindergarten Education held 12 meetings, received 140 briefs and attended 21 hearings in centers throughout the Province. In response to the investigation, the committee concluded that the time is right to implement publicly-supported…

Piaget explains the stage IV error as a failure to assimilate the new place of hiding rather than a forgetting of it. His hypothesis predicts that the likelihood of error should not vary with the length of the delay interval. Nine-month-old infants delayed 0, 1, 3, or 7 seconds before having the opportunity to search. Infants in all conditions,…

Although they have limited academic ability, mentally retarded children may be quite adept at social interaction or physical, artistic, or other tasks. Research was conducted to examine the creative, self-concept, and impulsive characteristics of MR pupils and to examine and compare, as to age and intellectual development, the performance of both…

This is the second of four reports representing an effort to develop a system of indicators of scientific technical information. This particular report is concerned with the data analyses which led to the system of statistical indicators described in the first report. It includes a discussion of the overall framework upon which the study was based…

Conflicting views have been put forward on the derivation of the distribution of solubilized molecules among micelles. This stems from failure to consider the arrangement of the solubilized molecules in the micelles. In the treatment presented enthalpy effects are ignored as they are not amenable to a simple general theory. (Author/BB)

Explains the link between educational broadcasting and information technology. Some aspects of knowledge organization for information retrieval are explored and illustrated with reference to the University of Aberdeen's Educational Broadcasting Database. A pilot exercise includes communication of user-selected data from the database to…

This paper examines reports of empirical research on Feuerstein's "Instrumental Enrichment" (FIE) as a method of teaching thinking skills and asks what can be concluded from these reports with regard to: (1) the nature and statistical reliability observed FIE effects and (2) the "amount" of FIE for effects to appear.…
