Willmott's comparison of General Certificate of Education (GCE) scores in 1968 and 1973 is reexamined. The trend toward an increasing percentage of students who pass is confirmed, but estimates of standard errors indicate that subtest differences may be attributed to the sampling plan. (CP)

Scores in reading and comprehension on the University of Minnesota Reading and Speed of Reading examinations for the years 1928 and 1978 were compared. The 1978 freshmen were found to be at least one grade level below their 1928 counterparts in vocabulary, reading comprehension, and rate of reading. (MLW)

Do junior high school students agree on the characteristics of competent teachers? This broad question was divided into three areas--academic characteristics, personality, and physical characteristics--and asked of junior high school students. (Editor)

A study tested a resampling methodology (bootstrap simulation) by examining the effects of class size and student motivation on students' ratings of teaching effectiveness. Results suggest that evaluations based on student ratings should look at more than class averages, and that class size and student motivation affect overall ratings. Examples…

Expresses the importance of scientifically based research in education reform and explains how to judge the validity of educational research. Describes control groups, randomized and matched experiments, statistical educational significance, sample size, and the difference between scientifically based and rigorously evaluated research. (Contains…

Provides a short BASIC program, RANVAR, which generates random variates for various theoretical probability distributions. The seven variates include: uniform, exponential, normal, binomial, Poisson, Pascal, and triangular. (MVL)

Data from a sample of Egyptian university students was used to analyze the determinants of secondary school choice and the factors likely to affect secondary school certificate marks. High social background as well as attendance at a private school have a positive effect on examination marks. (Author/MLW)

Maintains that few statistical representations are as tenuous as public opinion. Maintains that social studies students need to be taught to analyze statistical data carefully. Presents and discusses four guidelines for students reviewing statistical information. (CFR)

Concepts behind plausible values in estimating population characteristics from sparse matrix samples of item responses are discussed. The use of marginal analyses is described in the context of the National Assessment of Educational Progress, and the approach is illustrated with Scholastic Aptitude Test data for 9,075 high school seniors. (SLD)

Using the Mayo Older Americans Normative Studies (MOANS) group (526 55-to 97-year-old adults), factor models were examined for the Wechsler Adult Intelligence Scale-Revised (WAIS-R); the Wechsler Memory Scale (WMS); and a core battery of the WAIS-R, the WMS, and the Rey Auditory-Verbal Learning Test. (SLD)

Procedures for obtaining student samples for the National Assessment of Educational Progress (NAEP) and deriving survey weights for analysis of survey data are described. Sample designs are economically and operationally feasible, and weighting procedures result in increased precision of estimates as they account for the probabilities of student…

A stratified probability sample of 4,745 adults in Colorado was surveyed to determine the need for alcohol, drug abuse, and mental health services. Findings that variation in need prevalence across 48 subareas of the state substantially challenge the assumptions of a uniform rate of need in a state. (SLD)

Methods used to follow, for 18 months after pregnancy resolution, 241 premaritally pregnant urban adolescents in a longitudinal drug use study are described. One respondent dropped out after the first interview. Temporary attrition at each data collection wave was between 1 percent and 3 percent. Sample recruitment and retention are discussed.…

A study of job satisfaction at a college registrar's office investigated overall job satisfaction, physical working environment, motivational culture, and worker needs. Findings included significant differences in satisfaction between registration and admissions units. Recommendations for improved sampling, choice of variables, and research design…

University legal counsel advising public institutions about the constitutionality of student-athlete drug testing must be prepared to show that the need for such programs outweighs the invasion of privacy. Performance-enhancing drugs should be distinguished from ordinary street drugs because competitive pressures to use the former justify random…
