Estimates of program effects from a compensatory preschool intervention were investigated using econometric simultaneous modeling, latent variable structured modeling, and ordinary least squares regression. Data for 806 black children indicated that different quasi-experimental estimation methods that attempt to control for selection bias can…

Whether the external validity of the Personality Inventory for Children (PIC) was moderated by age, sex, or race was studied using 1,333 children and adolescents referred for mental health services. Race and sex generally did not moderate the relation of PIC scales to symptom checklists. Some relationships were age modified. (SLD)

The relationship between adolescent loneliness and factors associated with adult loneliness (attributional style, self-esteem, social anxiety, and social skills) was investigated for 107 male and 79 female ninth graders completing 7 difference measures. Social skills, self-esteem, and attributional style are significant predictors of loneliness,…

Examines extent that predictor variables commonly used as teacher admission, retention, and certification standards predicted teacher success. Sample included 207 teachers with BA degrees from University of North Carolina teacher education program during 1985-86 through 1989-90 and were currently teaching in North Carolina. Predictor variables…

Discusses how students generate meanings for mathematical word problems, develops a generative predicational model to account for students' comprehension of word problems, and describes an empirical study of Israeli sixth graders that was designed to test the model. Talk aloud protocols of the students are analyzed, and hypotheses tested are…

The general intelligence factor (g) was investigated using 170 university students across three batteries of ability measures: (1) a short-term memory battery; (2) the Multidimensional Aptitude Battery; and (3) a reaction time battery. Results support the notion of g and suggest short-term memory as an essential aspect of intelligence. (SLD)

This paper argues that efficacy of early intervention must be assessed in relation to both program and extra-program variables. A framework outlining five classes of independent variables and two classes of outcomes to be considered in efficacy research is presented, and regression and path analytic techniques are suggested as tools for addressing…

Describes research conducted with employees of the NCR Corporation that examined relationships between learning style preference, as measured by the Kolb Learning Style Inventory, and the effectiveness and acceptance of interactive video instruction to determine how best to individualize instruction.

Based on interview and survey data from 220 upper- and middle-level managers within a Fortune 500 manufacturing firm, this case study describes how differences in organizational values influence the frequency with which decision makers use oral, written, and electronic sources of information for environmental scanning.

Item response theory (IRT) is used to develop a form of adjusted cumulative grade point average (GPA) for use in predicting college academic performance appropriately for males and females. For 1,564 students at Stanford University (California), the IRT-based GPA was more predictable from preadmission measures than the cumulative GPA. (SLD)

An evaluation of the rules-of-thumb used to determine the minimum number of subjects required to conduct multiple regression analyses suggests that researchers who use a rule of thumb rather than power analyses trade simplicity of use for accuracy and specificity of response. Insufficient power is likely to result. (SLD)

Statistical analysis of racially polarized voting prepared for the Garza v County of Los Angeles (California) (1990) voting rights case is reviewed to demonstrate that ecological regression is a flexible, robust technique that illuminates the reality of ethnic voting, and superior to the neighborhood model supported by the defendants. (SLD)

The effects of time spent on reading at school and at home on 195 intermediate grade students' reading achievement was assessed. A stepwise multiple regression analysis, in which prior standardized reading comprehension scores served as a covariate, revealed that time spent on reading contributed significantly to reading achievement. (TJH)

A quiz is presented that may call the attention of school personnel to regression effects in educational measurement, and clarify the meaning of statistical regression for educators in schools. Ten questions and their answers explore regression in the contexts of classroom testing, grading, and performance assessment. (SLD)

Investigates the relative contribution of computer simulations and case studies for improving undergraduate students' self-efficacy in strategic management courses. Results of pre-and post-test data, regression analysis, and analysis of variance show that simulations result in significantly higher improvement in self-efficacy than case studies.…
