The paper presents a discussion of a theory of intelligence which postulates that intelligence develops rather than that intelligence is an innate ability possessed in full measure at birth. Discussion of unresolved issues surrounding their theory is presented. The effect of such a theory on science teaching is discussed. (RE)

Reports on twelve year-old students instructed in Nuffield Project and in "traditional" classrooms. A division of the subjects into two groups based on intelligence revealed significant differences on classification ability. Interaction effects were also observed. (CP)

Provides evidence to support the conclusion that relationships exist among Piagetian levels of intellectual development, intelligence quotient, content achievement, and inquiry skills in ninth and tenth grade biology students (N=92). (DS)

Discusses whether formal thought constitutes a structured whole and role of propositional logic in advanced reasoning. Presents aspects of advanced reasoning model, considering hypothesis generation/testing as central processes in intellectual development. Argues that advanced reasoning schemata are linked by these processes and should be…

To determine responsiveness to instruction, matched concrete operational seventh-grade (N=50) and college (N=72) students were given identical classroom instruction in probabilistic and correlational reasoning using biological concepts. Field dependence/independence and fluid intelligence were examined. Reasons why college students are more…
