This study was designed to examine the amount of incidental physical science knowledge possessed by fourth-, fifth-, and sixth-grade students in elementary schools in Western State of Nigeria, and to determine what relationship exists between the amount of such knowledge and the pupils' performance on science-related Piagetian tasks. The pupils…

Recent trends in college admissions are discussed in terms of their influence test validation procedures. In particular, the effects of new college admission practices are considered with respect to the problem of validating placement tests. Traditional test validation techniques are reviewed and compared to the needs specific to placement tests;…

The purpose of this study was to test the hypothesis that there are positive correlations among: (1) attitudes toward science, (2) self-concept, and (3) achievement of science process skills. The 68 students who served as subjects were juniors and seniors enrolled in science methods courses in elementary education. The Moore and Sutman (1970)…

The prediction of creativity is an intricate and difficult problem for which there is no currently accepted method of solution. At least two conceptually discernable types of creativity are identifiable in research on the topic. The first type conceives creativity to be a trait which is distributed across the population in a fashion analogous to…

Eleven indexes of rurality and their effect on the classification of Michigan's 83 counties were investigated. The indexes were based on different concepts of rurality: (1) percent of employment in agriculture, fishing, and forestry; (2) population density and distance to urban centers; and (3) economic conditions. Index rankings were compared to…

The study employs stepwise regression analysis to relate work and total job satisfaction with the following measures: job characteristics as reflected by job dimension scores and work quality dimensions, both being based on the Position Analysis Questionnaire; job-related interests expressed by job incumbents, as measured by the Job Activity…

As part of the Final Report of the National Study of American Indian Education, this paper reports on the reliability of rating scales used in analyzing the interviews conducted during the study. Approximately 4,000 interviews, which covered "adequate samples of people in the schools and communities" that were studied, were deemed valid as a…

Two theorems concerning F in analysis of covariance with two groups (experimental and control) and one covariable (pretest score) are presented. The first shows explicitly that F is a direct function of the ratio of the variance about the regression line for the total sample to the variance about the within-group regression line. The second…

"How interesting did you find the material in the unit which you just completed?" This and other questions were asked in a student questionnaire during the field testing and evaluation of twelve short units, "Episodes in Social Inquiry Series", developed by the Sociological Resources for the Social Studies Project. By assigning…

The assumptions of the classical test-theory model are used to develop a theory of reliability for criterion-referenced measures which parallels that for norm-referenced measures. It is shown that the Spearman-Brown formula holds for criterion-referenced measures and that the criterion-referenced reliability coefficient can be used to correct…

For a heterogeneous sample, the correlation coefficients between the Basic Interest Scales and the Occupational Scales and between the Basic Interest Scales and the Nonoccupational Scales of the Strong Vocational Interest Bland for Women (SVIB-W) are presented. Although the pattern of intercorrelations may be somewhat different for other samples,…

This study tested the relationship between self-perceptions of leader behavior by 57 directors of university conference operations, and their perceived degree of autonomy and role conception. The directors responded to an instrument consisting of five background questions, 100 leader behavior statements, 25 items on autonomy in decision making,…

This paper reports three studies designed to determine if significant increases could be made in the prediction of elementary school pupils' academic achievement by adding personality measures to intellectual measures after mental age and intelligent quotient leveling. A fourth study examined the utility of leveling pupils on socioeconomic…

An investigation was undertaken of the intercorrelations among residuals obtained by applying regression techniques under two conditions: (1) mean sixth-grade Metropolitan Achievement Test reading scores predicted by mean second-grade Stanford Achievement Test reading scores, and (2) mean sixth-grade reading scores predicted by mean second-grade…

Evaluated was the relationship of the personal and marital adjustment of 31 sets of parents to their own behavior as parents and the behavior problems of their children (mean age 7.7 years). Families who had been referred for behavioral counseling regarding child problems were given a diagnostic battery which included home observations as well as…
