An overview is presented of decision-oriented educational research, based on experiences in a large urban school district and on the literature. Alternative definitions of research use and evaluation use are discussed, with particular attention to the dissemination of research outcomes. (GDC)

Explores reasons for the tenuous relationship between educational research and educational practice. Suggests changes in research and policy to bring educational research directly to bear on educational problems. The major problem is that researchers are searching for variables that relate to improved outcomes, whereas educational innovators are…

Notes the inconsistent findings that characterize research on marital instability and proposes several potential methodological sources of these inconsistencies. Presents an illustrative application to data from two recent national representative probability samples. (JAC)

Reviews several potential problems that often invalidate statistical tests of social theories. Discusses how there may be very serious identification problems in the estimation of the relationship between executions and homicides, and that serious questions may be raised regarding the validity of any particular estimation of this relationship.…

Explains multiple regression, demonstrates its flexibility for analyzing data from various designs, and discusses interpretation of results from multiple regression analysis. Presents regression equations for single independent variable and for two or more independent variables, followed by a discussion of coefficients related to these. Compares…

To predict suicide, explicit causal models of suicide outcome are needed in which predictors are temporally ordered and then tested statistically. Because suicide is a dichotomous, nominal scale outcome, only certain statistics for prediction are appropriate. Logistic regression, which utilizes the likelihood ratio test of statistical inference,…

The purpose of "What Works in Reading?" was to identify the factors that contribute most strongly to achievement growth in reading. The study, which investigated fourth graders in 25 schools, was run jointly by the Philadelphia School District and the Federal Reserve Bank of Philadelphia, and the respect and understanding that developed…

This paper discusses path analysis and the applicability of this methodology to the field of family studies. The statistical assumptions made in path analysis are presented along with a description of the two types of models within path analysis, i.e., recursive and non-recursive. Methods of calculating in the path model and the advantages of…

Describes the method of discriminant analysis, including the concept of discriminant function, discriminant score, group centroid, and discriminant weights and loadings. Discusses methods for testing the statistical significance of a function, methods of using the function in classification, and the concept of rotating functions. Illustrates the…

Presents conceptual framework for organization of factors (independent variables) affecting online bibliographic retrieval. Roles that variables play in research studies are described and examples considering various elements--setting, user, request, database, search system, searcher, search process, search outcome--are provided. Twenty-one…

Reexamined previous statistical comparisons of two models for adolescent drug abuse using new statistical estimation methods in causal modeling not requiring assumptions about normally distributed variables. An asymptotically distribution free method shows that the models fit even better than assumed in the initial work. (Author/JAC)

With the development of refined theory and increased measurement sophistication in family research, multidimensional concepts and multiple indicators are appearing in the literature. This paper provides a nonmathematical introduction to canonical correlation analysis and three empirical examples that demonstrate the technique's applicability in…

The 1983 North Carolina Dropout Study and the 1988 North Carolina Follow-Up Dropout Study were conducted to provide baseline dropout data for North Carolina public high schools, to provide estimates of dropout rates, and to explore possible factors contributing to a student's decision to leave high school. The results of the 1983 study indicated…

Compiles data from 27 studies comprising the Cooperative Research Program in First-Grade Reading Instruction. Reveals ability to recognize letters of the alphabet prior to beginning reading instruction was the best predictor of first-grade reading achievement. Indicates various nonbasal programs tended to be superior as measured by word…

Three groups of secondary school students were identified in the sample of over 7,000 high school students from the 1987/88 California Substance Use Survey based on patterns of involvement with alcohol and other drugs. Of primary interest are high risk users (HRUs) who engage in socially deplored and often dangerous forms of substance use. HRU…
