THIS REPORT PRESENTS A DISCUSSION OF 2 TECHNIQUES WHICH CAN BE USED TO REPRESENT AND INTERPRET MULTIVARIATE STATISTICAL SYSTEMS WHEN IT IS FELT THAT THERE ARE CAUSAL RELATIONS BETWEEN SOME OF THE VARIABLES. THE BASIC TECHNIQUE IS PATH ANALYSIS AND THE OTHER IS ITS EXTENSION THROUGH THE USE OF RECURSIVE SYSTEMS OF EQUATIONS. THE ANALYSIS IS…

Experiments were performed to determine the feasibility of using ALCAPP as one form of on-line dialogue. Assuming the ALCAPP (Automatic List Classification and Profile Production) system is in an on-line mode, investigations of those parameters which could affect its stability and reliability were conducted. Fifty-two full test documents were used…

The principal aim of the study was to determine whether, in the verbal interaction in a group of nine adults engaged in adult education, a systematic relationship could be shown between members' ego-stage profiles and their patterns of participation. Active ego-stage profiles were constructed of basic ego identity concerns using Erikson's…

Several tasks were developed to investigate adolescents' ability to see correlations in data and to test hypotheses. Emphasis was placed on methodology: do students clearly understand the problem and do the tasks tap the skills they claim to? The 20 ninth-grade and 20 eleventh-grade boys and 15 college freshmen were tested. Most students did…

Utilizing data derived from the U.S. Census, a 10 percent stratified sample of U.S. population from nonmetropolitan counties (276 counties) as of 1950 was examined in terms of 2 opposing hypotheses: (1) the higher the level of manufacturing activity, the higher the quality of the housing in rural areas; and (2) industry attracted to rural areas…

Piaget has hypothesized that concrete and formal operations can be described by specific logical models. The present study focused on assessing various aspects of four concrete operational groupings and two variations of two formal operational characteristics. Six hundred twenty-two 9-14 year old students participating in the Human Sciences…

This study attempted to determine whether the mental test performance of 77 children tested at 6, 12, and 36 months of age could be predicted from scores on an Inventory of Home Stimulation used to assess the children's home environment during their infancy. The Inventory of Home Stimulation had six subscales: (1) emotional and verbal responsivity…

The results are briefly summarized of a study to investigate the relationship of factors other than job skills (such as social skills, life style, mobility, family relationships, and contextual factors) to the long range success of vocational and technical training programs. Data were gathered about students in secondary and postsecondary…

The report describes the Shared Process Evaluation System (SHAPES), a process analysis system designed to facilitate documenting, rationalizing, and evaluating community development projects. The evaluation process requires five steps. First, the project is described with respect to statements about the original problem situation and demographic…

Data derived from the Southern Youth Study (a randomly stratified sample of 250 black and 409 white males from Southern rural counties with lower than average annual incomes) were utilized to analyze veteran status as a determinant of occupational and educational attainment via the interaction effects between race, veteran status, and residential…

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…
