Author evaluated Dr. Thorne's psychological views, his approach toward diagnostic testing and the need for better methods of personality evaluation, and compared his attitudes and Thorne's regarding the development of clinical psychology. (Author/RK)

This paper focuses on Melvin Kohn's suggestive hypothesis that white-collar parents stress the development of internal standards of conduct in their children while blue-collar parents are more likely to react on the basis of the consequences of the child's behavior. This hypothesis was supported. (Author)

A personal understanding of the concepts of scholarship, knowledge, and research is presented. The basic task of scholarship is to study reality with a view to finding out what it is like, the relations of different parts to each other, and the applications to which the findings can lead. The scholarly search must be a rational procedure.…

Concepts from organizational theory are used to interpret and review major findings of school effectiveness research to develop a broader perspective for understanding school effectiveness. Results of school-effectiveness research in the Netherlands are compared with those from research in the United States and England. A more-or-less established…

This simple method for simulating the Central Limit Theorem with students in a beginning nonmajor statistics class requires students to use dice to simulate drawing samples from a discrete uniform distribution. On a chalkboard, the distribution of sample means is superimposed on a graph of the discrete uniform distribution to provide visual…

Power is an indicator of the ability of a statistical analysis to detect a phenomenon that does in fact exist. The issue of power is crucial for social science research because sample size, effects, and relationships studied tend to be small and the power of a study relates directly to the size of the effect of interest and the sample size.…

The problem of determing how many significant discriminant functions are present in a given data set for a one-way, fixed-effects multivariate analysis of variance design is studied using a Monte Carlo procedure. A variety of procedures, including the popular partitioned-U procedure, are compared with respect to their Type I error rates and power…

A correction of the standard F-ratio for unreliability of the dependent measure has recently been proposed by Winne; the rationale is analogous to that of correcting a correlation for attenuation. However, there are two problems associated with Winne's correction of which potential users should be aware. First, the corrected statistic, F*, has…

Part and bi-partial canonical correlations were developed by extending the definitions of part and bi-partial correlation to sets of variates. These coefficients may be used to help researchers explore relationships which exist among several sets of normally distributed variates. (Author)

A major factor in the failure to successfully implement an innovation such as team teaching, is the absence of a mechanism to identify and treat difficulties arising from the effort to implement the innovation. The hypothesis was tested that teachers who are ambivalent toward team teaching and teachers who experience frustration in attempting to…

This report presents the procedures, results, and conclusions of a study designed to compare the achievement in beginning college physics of students completing PSSC high school physics with students completing a traditional high school physics course. Factors of ability and achievement were held constant while scores on the criterion of marks in…

To test the hypothesis that learning depends on the influence and interaction of three primary variables--instruction, learner aptitude, and learning environment--an explanatory model was tested during the 1967-68 school year in an experiment conducted with the cooperation of a simple random sample of 56 teachers drawn from the National Science…

Three critical issues in the design and analysis of evaluation studies suggested at the conference are (1) the univariate versus multivariate dependent variable studies, (2) the choice of a response surface design over the conventional fixed model, and (3) the tendency to interpret every study as if it were being done for the first time. Taking…
