The program of research on teacher-student relationships described in this issue is an important part of the field of classroom learning environments, although it has its own distinctive and significant features. The questionnaire on teacher interaction (QTI), the main instrument used in this research, follows the strong tradition in learning…

Background information about the importance of improving educational productivity, Walberg's nine-factor model of educational productivity, and the general approach followed in educational productivity research are outlined. The approach is aimed at identifying factors linked to the achievement and attitude scores of students. (TJH)

Research syntheses of individual bivariate studies of the effects of specific predictor variables on student outcomes are considered. Walberg's nine-factor model of educational productivity is used to organize the syntheses and to identify aptitudinal, instructional, and environmental variables linked with student achievement and learning. (TJH)

Meta-analyses of past studies in numerous countries on factors influencing student outcomes are synthesized to examine educational productivity in the learning of science. A systems approach and Walberg's productivity model are used to perform the analyses. (TJH)

Major issues in models of student learning (Carroll's, Bloom's, and Glaser's models) are discussed, and a model that retains the salient features of these models (time, prior learning, and learning processes) is outlined. The final model also addresses other facets having unique effects on achievement and interactions among facets. (TJH)

A multivariate study of factors linked to science achievement and attitude scores of 9-, 13-, and 17-year-old students (1,960, 2,025, and 1,955 subjects, respectively) tested Walberg's model of educational productivity. Analysis of data from the 1981-82 NAEP Assessment in Science supports bivariate study results concerning the model's validity.…
