Tested two hypotheses: (1) formal reasoning is required to balance simple one-step equations; and (2) formal reasoning plus sufficient mental capacity are required to balance many-step equations. Independent variables included intellectual development, mental capacity, and degree of field dependence/independence. With 25 subjects, significance was…

Examines research in developmental psychology and science education that has attempted to assess the validity of Piaget's theory of formal thought and its relation to educational practice. Position papers (with little or no empirical support) are not included. (Author/JN)

Investigated is the extent to which students' nonscientific beliefs change by comparing before and after instruction as a function of students' reasoning skill. Nonscientific beliefs discussed include special creation, orthogenesis, the soul, nonreductionism, vitalism, teleology, and nonemergentism. (KR)

Studies the effect of intellectual development, degree of field independence, mental capacity, amount of prior genetics knowledge and amount of fluid intelligence on reading comprehension and/or genetics achievement of students enrolled in a nonmajor biology course. Concludes that developmental level was the most consistent predictor of…

Reviews the neural modeling principles of learning, perception, cognition, and motor control, discusses their applications to sensory-motor problem solving, and explores possible relationships between that pattern of problem solving and aspects of higher order formal operational problem solving. Cites implications for science education. (ML)

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…

This monograph describes the origins of the learning cycle, related research, and how future research might be conducted to further the understanding of theories of instruction. A wide range of information is synthesized, producing a coherent framework for better understanding the theory of the learning cycle. The monograph identifies various…
