Operationalizes a psychological theory of productivity with data from a large sample of 13-year-old students administered eight items concerning voluntary science activities in the National Assessment of Educational Progress (NAEP). Discusses validity of model of the productivity theory and usefulness of secondary analyses of NAEP data. (Author/JN)

The popular view of a permanent Black underclass falling farther behind an expanding Black middle class is disputed by empirical evidence that the underclass is experiencing upward mobility. The discrepancy stems from social scientists' overreliance on cross-sectional data rather than longitudinal data in analyzing economic change among Blacks.…

Argues that secondary analysis of existing data sets provides an important opportunity for science education researchers. Reviews basic arguments for secondary analysis (quality, cost, scientific merit of multiple analyses of a common data set), discusses new forces fostering these analyses, and provides three examples of secondary analysis…

Suggests how data from the Ginzberg-Yohalem Survey of Educated Women might be analyzed to address the Ginzberg-Yohalem Survey of (1) person-situation interaction; (2) attitudes and behavior; (3) attribution theory; (4) helping behavior; and (5) social motivation. (Author/GC)

Describes multidimensional scaling and cluster analysis and the type of problems they can help solve. Cites major literature sources concerning their use. Reviews applications of these methods in rehabilitation research. Discusses possible advantages of nonmetric data-reduction techniques over metric approaches, such as factor analysis. (Author)

Six areas of staff development program evaluation in which participants may be meaningfully involved are: (1) clarification of the program's goals; (2) development of a design for the evaluation study; (3) development of methods for measurement; (4) analysis of information; (5) response to evaluation instruments; and (6) reporting on an evaluation…

Analysis of U.S. census data provides evidence that decreased labor force participation of older people, 1980 to 1970, was due to the disproportionate growth in numbers of persons aged 65 or older and the growing economic dominance of industries that provide relatively few opportunities for older people's participation.

Used aggregate ratings of teacher behavior as data for a multitrait-multimethod validity analysis. Scaled ratings using Rasch latent trait scaling model and traditional scaling techniques. Compared Rasch-scaled multitrait-multimethod matrix to the traditionally scaled multitrait-multimethod matrix. Results showed Rasch scaling resulted in higher…

The developmental process of postsecondary administrators was studied at Rutgers. The research procedure, research population, typical survey questions, data analyses, and findings are reported. Five variables (entry level, performance-contingent rewards, performance appraisal process, level of formal education, job complexity, and responsibility)…

Low socioeconomic status, lack of equal opportunities, and high concentrations of minorities in urban slums were found to correlate highly with crimes committed by and against minorities according to this study. Studies indicate that violent and property related crimes are committed more often against Blacks than Whites at neighborhood and…

A model is described which illustrates two general uses of multiple analyses to evaluate quasi-experiments: obtaining estimates of the treatment effect, and checking the validity of the experiment. (MH)

Erroneous conclusions relating to the interrelationship among unemployment rates, demographics, and crime rates of Black youths are discussed. A reexamination of the data shows that crime by Black youths bears a close relationship with prevailing economic conditions. (Author/RC)

Argues that the field of educational administration can and should develop a systematic, cumulative, and practice-oriented body of knowledge to inform administrative practice that concentrates on practical appplications, maximizing student achievement, and the effects of administrative actions. (Author/WD)

A reanalysis of research reported in the "Journal of Industrial Teacher Education" demonstrates a tendency among researchers to base interpretations of data entirely on the results of tests for statistically significant differences. The appraisal suggests that several of the published findings should be reviewed using additional data…

The tailoring of grants-in-aid to wage levels in the localities which receive them enjoys growing popularity among federal policymakers; two ongoing programs illustrate the flexibility of this technique. The article describes the procedures currently used to index the CETA and Medicare programs and their data source, the ES-202 system. (CT)
