Compared are boys' and girls' abilities and achievement in a research class which included both classroom and research institute experience. It was found that boys were more active in classroom interactions and that the ratings of girls and boys were otherwise not significantly different. (CW)

Presented are the results of a pilot study used to validate an instrument designed to measure attitudes of young children toward women scientists. It was found that the instrument was reliable and was able to discriminate between groups on three dimensions of attitude. (CW)

The relationships between mathematical competencies possessed by students and selected student characteristics at the beginning of a semester were examined. The relationship between test scores and the type of mathematics courses taken during the semester students were enrolled in an introductory biology course were also investigated. (Author/CW)

Examined was the possibility that the language teachers use to communicate science content may provide the context in which students formulate a world view of science. Results are presented and the implications of these results for teacher education programs are discussed. (Author/CW)

Investigated was the relation between student ability to translate sentences into equations, equations into sentences, and student performance in formal operational reasoning, proportional reasoning, and introductory-level chemistry. Results indicate that students who lack formal operational skills may experience problems in the translation of…

Surveys of program graduates of a model science teacher education program were compared with responses from a national sample of exemplary teachers. Results indicated a high degree of similarity between the two groups and provided evidence that a good preservice science teacher education can have a positive effect on the development of preservice…

Presented is a study in which students' intellectual reasoning development was evaluated following instruction that emphasized formal operations in a traditional lecture format. Results indicated that formal-operational students had significantly more success in the three reasoning areas than transitional students and transitional students had…

Presented is a criticism of Lawson's (1988) article on the development of misconceptions of biological concepts. Lawson's response to this criticism follows. (CW)

Examined is the question of how science attitude scores can be expected to predict science-related behaviors. Discussed is a historical perspective of this problem and five attitude-behavior perspectives. A summary for science educators is provided. A list of 77 references is included. (CW)

Presented are the results of surveys given to high school science students measuring their beliefs regarding four kinds of study strategies, three types of motivational orientation to science, their reported ability, and attitude toward science. (CW)

In this project, a resynthesis of the research dealing with student performance in new science curricula was conducted using refined statistical procedures. Results generally supported earlier meta-analysis studies. (CW)

Presented are the results of a study of the effects of peer-led tutoring groups on achievement in college chemistry. Supplemental instruction was effective in increasing students' achievement in chemistry as measured by final grades in chemistry and responses to a questionnaire. (CW)

Investigated was the level of cognitive development of Afro-American students enrolled in general chemistry courses to determine the strategies used by both successful and unsuccessful problem solvers in solving stoichiometry problems. Results indicated that a higher level of cognitive development may be crucial in solving more sophisticated…

The impact of enhanced observation or enhanced prediction on scientific reasoning about heat energy and temperature problems was investigated. Instruction was successful in improving prediction and observation skills in the microcomputer-based laboratory environment. (CW)

Word associations were used to map high school students' concepts of "chemical equilibrium" and "equilibrium." It was found that the preconception of the two concepts was differentiated on noncritical dimensions. (Author/CW)
