Determined if grouping preservice elementary teachers (N=91) in physical science laboratories by their formal reasoning ability affected: (1) their science content achievement; (2) the learning environment in the laboratory; (3) their formal reasoning ability; and (4) the relationship between individuals in a particular group. (Author/JN)

Reports on the development of a 19-item, Likert-type instrument that measures the attitudes of preservice and inservice teachers toward energy conservation. Focuses on the nine-step process used in developing the instrument. (JN)

This study demonstrated a direct relationship between achievement level (measured by responses to biological items on the 1977 National Assessment of Educational Progress's science survey) and concept emphasis in biology textbooks. In addition, recommendations of Project Synthesis were not found in newer biology textbooks. Other findings are…

Investigated the development of formal reasoning among students (ages 10-18 years) from predominately White, middle-class communities located in rural, suburban homogeneous, and suburban heterogeneous areas. Results indicate clear differences among communities in formal reasoning ability. Implications for using science instruction to promote…

Explored Morine and Morine's ("Discovery: A Challenge to Teachers") assumptions regarding age and cognitive development of students (N=174) successfully utilizing structured inductive and semi-deductive inquiry strategies. One finding noted is that age has made a significant difference on achievement for both strategies. Implications for science…

Assessed the effectiveness of conducting an elementary science methods course based on the Concerns Based Adoption Model (CBAM) on the concerns and attitudes of 85 preservice elementary teachers. Results indicate that neither traditional nor CBAM methods courses proved superior in affecting concerns or attitudes of the preservice teachers.…

Investigated what effects two instructional strategies (related to student use of manipulative materials) would have on second-grade students' (N=96) development of logical structures. Also examined the effects of sex on logical development. Results indicate that supplying manipulative materials alone is not adequate in promoting development of…

Investigated changes that occurred in sixth- and seventh-grade teacher and student discourse when teachers endeavored to implement extended teacher wait-time in a sequence of seven lessons related to probabilistic reasoning. Results indicated that teacher wait-time increased from an average of 1.9 to 4.4 seconds during the lesson sequence. (JN)

Identifies promising areas of aptitude-treatment interaction research (ATI), including research related to general ability, anxiety, prior achievement, and achievement motivation. Also provides general methodological ATI guidelines for science educators. (JN)

Describes a technique that can be used to construct variables from clinical interviews that can be used in quantitative analyses. The technique involves the representation of each proposition a student uses in terms of a standard set of underlying predicates, concepts, and relationships among concepts. (JN)

Twenty-two high school biology textbooks published between 1963 and 1983 were analyzed for their treatment of social issues. Results showed that attention to social issues decreased in these textbooks between 1963 and 1983. Implications of the results for biology education in the 1980s are discussed. (JN)

Long-term retention effects of two methods of instruction used one year earlier to teach field-dependent and field-independent sixth-grade students to control variables and to transfer this ability to novel tasks were investigated. Also examined whether or not uninstructed seventh-grade students had acquired this ability on their own. (Author/JN)

Determined whether chemistry students (N=332) understood analog tasks that could be used for teaching the mole concept. Also identified possible difficulties that students might have in solving mole problems. Seven major conclusions are reported and discussed, including the finding that two-step problems were more difficult to solve than one-step…

Investigated the relationship between teachers' (N=35) ability to understand science processes and to control variables and students' achievement in science content and processes. Results indicate that teacher ability to control variables is a more valuable characteristic than the understanding of science processes for student achievement.…

Cognitive and affective outcomes of a class visit to a participatory science museum were examined by comparing responses of 416 fifth and sixth graders randomly assigned to four conditions (control, exhibit, lesson, exhibit followed by lesson) and two tests (verbal and visual). Results and implications for science education are presented.…
