This report describes a large scale research effort to validate and improve the Armed Services Vocational Aptitude Battery (ASVAB) aptitude area (AA) composites now used by the Army to select and classify enlisted personnel. Data were collected from existing Army sources on over 60,000 soldiers and over 60 Military Occupational Specialties (MOS).…

The effects of the violation of the assumption of normality coupled with the condition of multicollinearity upon the outcome of testing the hypothesis Beta equals zero in the two-predictor regression equation is investigated. A monte carlo approach was utilized in which three differenct distributions were sampled for two sample sizes over…

Reports use of social networking to recruit 64 Mexican-American children for an assessment of diet and exercise habits. Describes friendship, social, consanguineal, and coparenthood networks. Compares results of direct contact versus network contact. Discusses implications for recruiting ethnic groups for research. (LFL)

This paper examines issues related to the statistical power of impact estimates for experimental evaluations of education programs. The focus is on "group-based" experimental designs, because many studies of education programs involve random assignment at the group level (for example, at the school or classroom level) rather than at the student…

The Schools and Staffing Survey (SASS) is the largest sample survey of the characteristics and conditions of U.S. public and private schools and their teachers and principals. This booklet provides an overview of the aims of the SASS and the information it provides. In 1999, nearly 124,000 SASS questionnaires were mailed to collect information on…

The 1996 National Household Education Survey (NHES:96) was a random digit dial telephone survey of households that was developed by the National Center for Education Statistics and conducted by Westat, Inc. The NHES:96 included two topical survey components, "Parent and Family Involvement in Education," (PFI) which collected data about…

This volume documents the data collection of the 1990-91 Schools and Staffing Survey (SASS). People wishing to determine whether their research needs can be served by SASS data will find a description of the survey's contents and objectives in the Overview. This volume contains the following chapters: (1) "Overview"; (2) "Changes in…

A nationally representative sample of eighth-graders were first surveyed in the spring of 1988. A sample of these respondents were then resurveyed through four follow-ups in 1990, 1992, 1994, and 2000. On the questionnaire, students reported on a range of topics including: school, work, and home experiences; educational resources and support; the…

This article discusses the advantages and disadvantages of the Vineland Adaptive Behavior Scales for measuring adaptive behavior in adults with mental retardation. It concludes that the advantages of the coverage of the main domains of adaptive behavior, their standardization, impressive psychometrics, and brevity are becoming outweighed by…

A meta-analysis determined the importance of feedback in computer-based learning; 59 studies were collected and evaluated for inclusion in the meta-analysis in terms of design, sample size, and availability of appropriate statistics. Achievement outcomes were found to be greater for the feedback group than the control group. (AEF)

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)

This study examined the structure, distribution, and correlates of a new measure of self-reported callous-unemotional (CU) traits in 1,443 adolescents (774 boys, 669 girls) between the ages of 13 to 18 years. The Inventory of Callous-Unemotional Traits was subjected to exploratory factor analysis and confirmatory factor analysis. Exploratory…

A review of relevant literatures led to the construction of a self-report instrument designed to measure two subtypes of student engagement with school: cognitive and psychological engagement. The psychometric properties of this measure, the Student Engagement Instrument (SEI), were assessed based on responses of an ethnically and economically…

Using a sample of 522 students at a Lutheran university in the Southwestern United States, researchers examined differences in the predictive strength of high school grades and standardized test scores for student involvement, academic achievement, retention, and satisfaction. Findings indicate that high school grades are stronger predictors of…

The author conducted an empirical study based on structural equation modeling with a convenience sample of 246 individuals with the goal of demonstrating that recycling behavior is a routine conduct and should be addressed as such in educational materials. Although the classic hierarchy of effects dominates the interpretation of recycling behavior…
