Eight discriminators were identified and data were obtained from the records of 80 graduate students who attained one of four achievement levels at the conclusion of a beginning course in educational statistics. Although the internal discriminatory power of the set of eight measures was very high, estimates of the true power were discouragingly…

Described is a study to determine the degree of relationship between selected classroom and teacher variables and science teaching strategies. The perceived strategies were recorded and measured by the Class Activity Checklist (CAC) which is a modification of the Science Class Activities Checklist (SCAC), (Yeany, 1974). The observed teacher…

Properly manipulated residuals resulting from "status predicting status" regressions constitute a precise and unique measurement of status inconsistency without the definitional and methodological problems and limitations of simple and simultaneous cross-classification techniques associated with the typical "dummy variable regression" approach.…

The paper states and proves three propositions regarding the usefulness of the ITED (Iowa Tests of Educational Development) in preparing adult basic education students to take the GED tests. The first proposition, that the ITED can be a useful practice test for GED candidates, is supported by the fact that the ITED tests are designed to measure…

Described is a three-year study which concentrated on determining why freshmen in college remain in or leave engineering programs. Three aspects of the study are reviewed, and one of them is analyzed in depth. The latter compares the perceptions of 2,600 freshmen while still in engineering to their status as sophomores. The categories of academic…

This volume presents a compilation of more than 70 studies on the prospective scientist and his career. These studies range from childhood, family influence, and academic experiences, to the intellectual and personality traits which have been examined in the past as precursors to choosing science as adult work. The mechanisms involved in…

The conventional paradigm for testing expectancy theory predictions of work behavior has been to correlate expectancy-value reports with concurrent measures of motivation and performance. Although this static, two-variable approach has typically yielded statistically significant results, correlations have not been sizable. This study, using a…

The international system exhibits very sharp phase boundaries, the most striking of which is the boundary between war and peace. A phase boundary for water would be the difference between water and ice, influenced by pressure and temperature. Similarly the phase boundary between war and peace is influenced by national strength and stress. Although…

The effects of physical attractiveness, warmth, and sex of an adult model on imitation behavior of adult males and females were investigated. Subjects were randomly paired with confederates of low or high facial attractiveness who interacted with the subject in a cold-unfriendly or warm-friendly manner. The imitation task involved the confederate…

Mount Royal College, a Canadian community college, has an open door policy on admissions. Hence it needs a strong counseling division in order to place entering students at appropriate skill levels. Since the American College Testing Program tests have seen limited use in Canada, research is needed to establish and validate local norms. The…

This final report indicates the general areas of investigation in a program of research in the prediction of personal adjustment, conducted over a seventeen-year period. The crucial problems in the prediction of personal adjustment are fundamentally concerned with the data matrix which reflects the experimental designs and displays the essential…

Personality and attitude measures taken before training (of 70 primary grade student teachers and 71 teachers of grades 4-9) were compared, by multiple linear regression analyses, with instructor, self, and pupil evaluations of their teaching performance, at the end of training. Pupil evaluations were highly reliable; instructor and self-ratings,…

A battery of 11 nonverbal tests were administered to a sample of 2,362 non-prior service enlistees who had been selected to one of seven technical schools. The usefulness of additional aptitudinal and educational data was also investigated. The number of significant relationships between certain nonverbal tests and final technical school grade…

In recent studies, several structural variables have accounted for a good portion of the score variances on verbal problem solving tests. This study investigated changes in the variance accounted by structural variables on problem solving tests when subjects were given instruction to overcome the structural variable influence. Effects on subjects'…

The major purpose of this study was to determine whether data from the 1970 Census could be used to account for at least 70 percent of the variance in grade-level achievement scores in the elementary schools of a big city, without including variables directly denoting race or ethnicity. This goal was attained when it was found that a regression…
