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…

Students (n=46) were assigned to one of three instructional groups (descriptive, question design, and hypothesis testing) to test the hypothesis that descriptive learning cycles are not sufficient to stimulate students to reason at a formal operational level. Analyses indicated that the hypothesis-testing group exhibited a significant increase on…

Attempts to show that not only can density be taught to lower ability pupils but that by doing so, there is the possibility of assisting pupils to develop their reasoning powers. Lists teaching activities that help in this process. (CW)

The reasoning abilities to be expected of the concrete operational and formal operational student, the percentage of secondary science students that are capable of each type of reasoning pattern, and effective strategies to teach science to concrete reasoners are described. Implications for curriculum development are discussed. (KR)

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)

Investigated were gender-related differences in the relationship between the development of formal reasoning skills and learning interests during the early adolescent stage. Results indicated that adolescent boys appeared to develop patterns of formal reasoning before their female classmates. Differences in subject preferences were also found. (CW)

Analogies and examples from student's experiences are frequently cited as important to teaching conceptual material. This study was conducted in order to explore the effectiveness of an analogical teaching technique, which uses a connected sequence of "bridging" analogies, compared with a more standard teaching-by-example technique. The…

A teaching procedure and a curriculum construction model known as the learning cycle is described in this paper and research findings are discussed. Questions investigated include: (1) would students achieve more content understanding if taught with the learning cycle or exposition?; (2) would more content retention be evident if measurements were…

This study investigated preservice elementary teacher reasoning ability levels, science anxiety levels, and content achievement in a large midwestern university. Pretest and posttest measures were taken on three dependent variables: (1) reasoning ability (cognitive development); (2) science anxiety; and (3) science content achievement. In…

Previous research concerning the cognitive abilities of high school students has indicated that a substantial number of students enrolled in secondary science courses do not conceptualize at the formal-operational level. Further, results indicate that achievement levels in chemistry coursework are significantly affected by, not only cognitive…

Describes a study which was designed to determine the effect of a 25-hour introductory qualitative analysis course on high school students' understanding of formal concepts related to electrolytes. Suggests that introductory concrete experiences better prepare students to deal with more formal abstract concepts. (TW)

Popular sentiment toward the teaching of thinking skills and, in particular, higher order skills, is on the rise. Many people are wondering about the best way for teachers to foster the growth of reasoning skills in their classrooms. This study attempts to improve the teaching of reasoning by investigating teaching behaviors or characteristics…
