To facilitate meta-analysis of diverse study findings, a mixed linear model with fixed random effects is presented and illustrated with data from teacher expectancy experiments. The standardized effect size is viewed as random and the variation among effect sizes is modeled as a function of study characteristics. (Author/BS).

Describes experiments relating information to decision making. The experiments were developed to validate previously suggested conceptual model of information flow and its relation to decision making and to establish specific values for significant parameters involved. Background and summary of recent research and experimental design and research…

A meta analysis of research on children's attributions for success and failure was conducted to test the adequacy of the egotistic bias hypothesis for children in grades one to seven. Results supported the egotism hypothesis and indicated that both question wording and research context are important determinants of children's attributions.…

Given the increased data-based capabilities of educational institutions, educational researchers should have more opportunities to use sequential designs. This paper illustrates how to analyze educational data from a cohort-sequential design. University data pertaining to grade inflation were analyzed using a variant of multiple regression.…

The appropriateness of within-course time series analyses for instructor ratings and the potency of inducing rater perceptions of the rating process as an interactive variable in course evaluations were assessed. A specific positive psychological set prior to evaluation tended to produce more favorable evaluations than general, brief instructions.…

Using observational data on classroom teachers, statistical procedures are presented for studying two questions on the stability of teacher behavior over time: (1) Is the individual teacher's behavior consistent? and (2) Are individual differences among teachers consistent? Approaches and methods of previous temporal stability studies are…

Argues that experimental and field research can now demonstrate causal relationships between teaching techniques and learning, and that effective teaching practices can be taught. Urges, therefore, that improving teacher education be given high priority. (MCG)

Examines usefulness of DIALOG as legal research tool through use of DIALOG's DIALINDEX database to identify those databases among almost 200 available that contain large numbers of records related to federal securities regulation. Eight databases selected for further study are detailed. Twenty-six footnotes, database statistics, and samples are…

Describes design and development of a thesaurus based on lexical-semantic relations, and compares results of experiments with queries enhanced using thesauri based on several different groups of relations against performance with original queries run on IRS information retrieval system developed at Illinois Institute of Technology. Twenty-one…

Data from a 1977 telephone survey of 501 urban to rural North Carolina migrants show global satisfaction measures reflect more than is included in standard lists of community attributes and reflect satisfaction with few attributes in particlar. The analysis demonstrates community satisfaction can help explain respondents' potential for moving…

Within-class regression is a method, developed in this paper, of comparing a large number of nonequivalent groups. This study indicated that within-class regression was a less biased method of data analysis and will yield more accurate estimates of treatment effects than analysis of covariance. (PN)

In behavior research using cognitive and affective measures, there is often incongruity between the statistical analysis employed and the intended inference. This paper argues that incorporating items as levels of a random facet via generalizability theory allows the statistical examination of the inferential question in the desired universe of…

Discusses a case study describing the philosophy of teaching design to architecture students as practiced by one professor. A model of his architectural design curriculum emerged. Three issues arose: constructing theory from data grounded in experience, posing appropriate research questions, and understanding the roots of ethnographic inquiry.…

Reasons for carrying out cross-cultural and international health education research are presented, along with suggestions for adapting research methods to different cultures. Selection of appropriate topics, research design, development of measurement instruments, and data collection methods are considered. (PP)

Examines data analysis at three levels: analysis of data; secondary analysis is the re-analysis of data for the purpose of answering the original research question with better statistical techniques, or answering new questions with old data; and, meta-analysis refers to the statistical analysis of many analysis results from individual studies for…
