A visual display is introduced that enables one to compare the predictive validities of all possible non-negatively weighted sums of two predictors. This two-predictor validity curve assesses the level of predictability of a criterion from composites of two predictors. Derivations are presented for the general case. For illustrative purposes, the…

Fertility research among four groups of Chicanas showed intragroup differences in fertility rates and in relationships between fertility and independent socioeconomic variables. A literature review suggested that research on minority group fertility failed to recognize intragroup variations. Data from the 1980 Public-Use Microdata Sample yielded a…

This paper describes the Multiple Assessment Programs and Services (MAPS) Placement Research Service. Students entering nonselective colleges show a wide range of ability. The College Board offers these colleges a number of tests of reading, writing, and mathematics skills for use in placing students appropriately. The MAPS Placement Research…

The purpose of this study was to examine the nature of the expectancy-performance relationship for each sex and to determine whether cross-sex comparisons are appropriate. Students' expectancies for academic performance and the relationship of the expectancies to actual grades were examined. Subjects were 331 students (168 women and 163 men)…

This nationwide study examined the following factors in terms of predictive relationships between home environment and child adjustment within mother-employed households: (1) marital status; (2) number of hours worked per week; (3) full- versus part-time employment; (4) mother's occupational classification; (5) family income; (6) child rearing…

This report addresses the problem of sample size in developing prediction equations for college freshman grade averages under the American College Testing (ACT) Assessment Program. For the ACT Assessment, the prediction weights are estimated by standard least squares procedures. Because prediction weights are estimated regression coefficients…

Background information needed to understand the literature on the impact of price on college attendance (i.e. price-response literature) is provided. After briefly introducing price theory and its use in demand studies in higher education, the major expository articles are reviewed, and major analytical methods used by researchers are examined.…

The single parent who has to assume the role and the responsibilities of both mother and father provides a different sex-role model for the child than that provided in the two-parent family. Research has indicated that single parents are more androgynous than parents in intact families. To investigate the sex roles of 332 college students (213…

A model of internal principle for integrating past research findings on adult altruism postulates that although individuals' shared beliefs result in significant group effects, there remains a significant portion of variation due to a subject's "factor" or unique internal rule. To examine the influence of both the level (degree or amount) and the…

A study of the effect of implementing educational innovations in local schools across the country explored several factors affecting successful improvement. This paper provides a general overview of the interrelation among these factors, with illustrative diagrams. Particular attention is paid to innovations requiring major changes in teacher…

The purpose of the present longitudinal study was to determine how well a broad, comprehensive battery of tests administered in kindergarten predicts reading achievement in elementary school grades 1 through 6. The test variables were reduced to six predictive factors by factor analysis, and these, together with the variables, Child's Sex and…

This paper reports the results of a longitudinal study of the relationship between affect and achievement in high school science. The conceptual model for science-related affect proposes that students' enjoyment in, and enthusiasm for science are determined by their perceptions of their past performance in science, their expected future…

Results are presented from a study examining the organizational decision process used by graduating students to select an organization for which to work. Since college recruitment efforts provide more than 50% of the new qualified individuals hired each year, a better understanding is needed of how these students make the decision. The study…

Valid indicators for a school district's Chapter 1 program that would help districts make decisions and shape policy are defined and explored. The March 1988 report of the School District of Philadelphia's Chapter 1 task force proposed a 2-year phase-in of a totally restructured Chapter 1 program for the Philadelphia schools. The definition of…

The second phase of a 1977 University of Pittsburgh research study that focused on the resistance to technology in libraries, this parallel study of library school students and faculty continued the investigation to determine: (1) the extent to which technological transformation of library systems will tend to encounter resistance as…
