An increasing effort has been put into dealing with the question of time-series analysis regarding institutional efficiency, including in the area of higher education. Universities are important institutions for economies and societies and are expected to provide excellence as well as efficiency in their processes and outputs. This is reflected in…

Evaluators of education interventions are increasingly designing studies to detect impacts much smaller than the 0.20 standard deviations that Cohen (1988) characterized as "small." While the need to detect smaller impacts is based on compelling arguments that such impacts are substantively meaningful, the drive to detect smaller impacts…

In this paper, tables for the appropriate sample sizes are presented and discussed in the context that the determination of the effect size must precede the determination of the sample size. (Author/PN)

Results from numerous school- and teacher-effectiveness studies suggest that variation between classes is more significant than variation between schools, though evidence often seems contradictory. This article considers why different studies generate different findings, identifies key study design issues, and relates these observations to…

Psacharopoulos has found a declining rate-of-return to education pattern across levels of per capita income, using international data. A reexamination of Psacharopoulos's cross-country data refutes his declining rate-of-return hypothesis and points to diversity of cross-country experience as a possibly significant factor in interpreting the data.…

The Schools and Staffing Survey (SASS) is an integrated set of surveys that has been conducted by the U.S. Census Bureau for the National Center for Education Statistics (NCES) in 1987-88, 1990-91, and 1993-94. In each of those school years, the Census Bureau also conducted a reinterview of the administrators, schools, and teachers. This report…

Since its appearance in 1974, the Snyder Self-Monitoring Scale has been employed in research dealing with self-presentation, attribution, and attitude expression. The Scale was developed to measure the degree to which people are concerned with the social appropriateness of their behavior, are aware of relevant social cues, and regulate their…

During round 16 of the National Longitudinal Survey of Youth (NLSY), 900 NLSY sample members were randomly assigned to be interviewed about the period since their round 14 interview. Their responses were compared to those of approximately 8,000 NLSY sample members who were assigned to be interviewed about the 1-year period since their round 15…

One of a series of annual studies undertaken by the Library Research Center for and on behalf of the Illinois State Library, this report provides a detailed, question-by-question examination of the 143 responses (84% of the 170 Illinois academic libraries polled) to the 1981/82 Higher Education General Information Survey/Library General…

This study of early childhood and the family in member countries of the Organisation for Economic Co-Operation and Development (OECD) employs two statistical approaches to the problem of providing an accurate picture of modern conditions of family life. A classical demographic approach to population studies is initially used, then is critiqued,…

In 1976, a study determined that student retention had increased markedly following Barstow College's transition from a semester to a quarter system. In 1979, another study was conducted to determine: (1) the accuracy of the 1976 figures; (2) the effect of the shortness of the time period considered in the 1976 study on its reliability; (3) the…

In 1991, a national survey was conducted of institutional research directors at 150 two- and four-year colleges to investigate practitioner perceptions of institutional research effectiveness and productivity. Randomly selected directors of institutional research were mailed a one-page questionnaire, requesting information about institution size…

Volume 2, the second of eight publications developed by the Intercultural Development Research Association (IDRA) as part of the "Texas School Dropout Survey Project," focuses on the issue of the computation of a dropout rate. Three important factors which influence the mathematical computation of a dropout rate are identified: time…

This 4-year longitudinal study of logical reasoning found complex interrelationships among different cognitive processes of children ages 6 to 15. Piaget's stage theory is discussed in the introduction, with a focus on the concrete operational stage in middle childhood. In the study, a representative array of logical concept tasks and short-term…

The advantages that computer adaptive testing offers over linear tests have been well documented. The Computer Adaptive Test (CAT) design is more efficient than the Linear test design as fewer items are needed to estimate an examinee's proficiency to a desired level of precision. In the ideal situation, a CAT will result in examinees answering…
