Despite the centrality of the informal manufacturing sector ("Jua Kali") to the Kenyan society and its richness in scientific phenomena, there is no strong link between activities in the Jua Kali and school science. And, although there has been an ongoing public discourse in Kenya to industrialize, this hope is unlikely without…

Presents meta-analysis of 54 articles and dissertations dealing with cognitive preferences. Information provided includes: test reliability; comparisons by country, grade level, gender, disciplines, and curricula; relationships between cognitive preferences and career orientation, science achievement, interest, and aptitude; and effect sizes.…

Investigates the effect of increase of the M demand of chemistry problems, having the same logical structure, on performance of students having different functional M capacity, cognitive style, and formal operational reasoning patterns. (Author/YP)

Focuses on the enhancement of chemistry students' skill in problem solving utilizing problem categorization techniques. Indicates that explicit training in categorization skills can lead to higher achievement in complex problem-solving situations but that such achievement may be limited by the lack of linkages between students' conceptual…

Presents study findings which explored the effect of teacher reasoning level and teaching style preference on improvement in student-reasoning ability. Reports that students of concrete operational teachers and of inquiry teachers showed greater gains in reasoning ability than students of formal operational teachers and of expository teachers. (ML)

Reports on students' study and drawing of five electronic circuit diagrams. Concludes that the success of the students depended upon the amount of detail in the instructional diagrams. (RT)

Examined is the predictive value of the cognitive variables of developmental level, mental capacity, cognitive style, short-term storage space, and numerical inductive reasoning for student achievement in college science. Included is a strategy for the development of materials which would allow students to develop problem-solving skills. (KR)

Compares models of the classroom dynamics for a traditional laboratory setting and a problem-solving-centered environment, both at the eighth grade science level. Descriptive data indicate no differences in the models, whereas path analyses suggest that, in the problem-solving model, student behaviors significantly correlate to lesson structure,…
