Investigated factors which influenced teachers' (N=5) behaviors during the implementation of an audio-tutorial freshman college biology course in a high school setting and developed a structural model showing the interrelationships of these factors. (JN)

Investigated classroom management practices in 26 classes taught by 13 junior high and middle/junior high school teachers using student-on-task, off-task, and disruptive student behaviors as primary criteria of management effectiveness. Effective management practices for general classroom procedures, laboratory procedures, managing student…

Reports on the development of a paper-pencil instrument which consists of five concrete experiences related to environmental concepts. Results indicate an acceptable level of validity. Results also show that the reasoning level of adolescents was well below the theoretical levels predicted for them by theory. (Author/JN)

Results of this study indicate that students' (N=155) self-concepts and gender role perceptions were related to both achievement and attitudes toward science, but more related to attitudes than achievement. In addition, these relationships became more pronounced for students as they matured from seventh to eighth graders. (Author/JN)

Investigated: (1) "potent" testing cues that were identified by high-test-anxious (HTA) and low-test-anxious (LTA) undergraduate students (N=133); (2) differences between HTA (N=93) and LTA (N=40) students for frequencies and intensities of responses to testing cues; and (3) differences between HTA and LTA students for attentional direction to…

Applies Kuhn's model of the structure of scientific revolutions, Popper's hypothetic-deductive model of science, and Lakatos' methodology of competing research programs to a historical biological episode. Suggests using Kuhn's model (emphasizing the nonrational basis of science) and Popper's model (emphasizing the rational basis of science) in…

Determined which of 10 rational thinking powers are measured by 12 commercially-available standardized science tests. One result reported is that 90 percent of the test items required only recall. The conclusion was drawn that the producers of standardized tests are not concerned with measuring student achievement of the rational powers.…

Describes methods designed to add new studies to published meta-analysis results, focusing on a procedure using Bayesian analysis and showing how new findings complement previous meta-analysis and extend its conclusions. Also considers how studies are to be weighted, which variables are to be examined, and how often meta-analyses are to be…

Tested the effect of two systematically designed persuasive communications on attitudes toward energy conservation of 85 preservice elementary teachers differing in energy-related developmental advancement. One finding is that two-sided communication was more effective than one-sided communication regardless of level of developmental advancement…

A multi-institutional project was initiated to integrate findings of research studies directed toward major science education research questions. Overall operation of the project, research questions identified, and some rudiments of meta-analysis are described. (Author/JN)

Summarizes results of the meta-analysis of 105 research studies dealing with effects of new science curricula on student performance. Twenty-seven different new science curricula involving one or more measures of student performance were included in the analysis. Positive performance patterns were found in all new curricula examined. (JN)

Reports results of the meta-analysis of 130 research studies on effects of instructional systems used in science teaching. Studies coded gave rise to 341 effect sizes. Systems examined included audio-tutorial, computer-linked, individualized, and media-based instructional systems, personalized system of instruction, mastery learning, self-directed…

Two areas of research were explored in this meta-analysis: comparison of inductive versus deductive approaches and use of advance organizers. The study involved 128 characteristics for 39 studies spanning the period from 1957 through 1980. Coding variables included 57 concerned with treatment features and 12 with outcome attributes. (Author/JN)

A meta-analysis was conducted of 65 studies related to relationships between science teacher background characteristics and either their classroom behavior or student outcomes. In general, low relationships were found between these characteristics and classroom teaching behavior and student outcome characteristics. Summary tables showing strongest…

Relationships of student characteristics to student performance/attitudes were explored by meta-analysis for studies for years 1960-1981. Six characteristics (general ability, language ability, mathematics ability, socio-economic status, sex, and race) were selected for inclusion in the study. Indicates strong positive relationships between…
