Introduces biology teachers to the central ideas of Piaget's theory of intellectual development. Also presents a scheme of biology instruction and classroom procedures based on a Piaget-related theory of learning. (PEB)

Assesses the physics, chemistry and biology content of the Nuffield Combined Science Course used in British schools by experimental testing to children's understanding of the course. A model by which the pupils' achievement is mapped to an estimate of their maximum Piagetian level of thinking is presented. (HM)

Examines the relationship between Piagetian stage of development and achievement on the Australian Science Education Project (ASEP) unit "The Human Machine." Fifty-seven secondary school age boys took the Tisher-Dale "Understanding in Science Test" as a measure of cognitive development as well as the ASEP unit exam. The…

Reports results supporting the theoretical rationale that there are certain cognitive skills, including data interpretation, identification of assumptions and hypotheses, and controlling of variables, that appear to be necessary for successful understanding of the heterotroph hypothesis, as presented in the BSCS Blue Version. Implications for…

Four types of proportionality problems were administered to: (1) secondary school students who were enrolled in Project Physics, and (2) students not enrolled in physics. Both samples were randomly selected. Groups were not found to differ significantly in problem solving ability but both revealed that the ability to solve certain problems was…

Identified are common features of the present implementation of new school physics teaching in Southeast Asia. Implementation aids, methods, and teacher comprehension, student cognitive levels, learning styles, and a more functional physics curriculum are discussed. (DS)

The purpose of this study was twofold: first, to answer the question of which abilities, from a selected set of 12 abilities from the structure-of-intellect model of Guilford, were related to achievement in Physical Science Study Committee (PSSC) physics, and, second, to determine how the physics achievement prediction properties of these…

Describes some of the conceptual, measurement, and methodological problems associated with evaluating science curricula in terms of their impact on students' content-free cognitive outcomes. A study of the effects of including ASEP (Australian Science Education Project) materials into a seventh-grade program revealed several significant…

Studies the scientific curiosity and inquiry of 226 high school students from grades 10 to 12 who were studying the Israeli adaptation of the Biological Science Curriculum Studies (BSCS) program in eleven different schools representing city and Kibbutz Schools in Israel. (HM)

Twenty-three high school biology students were individually administered three conservation tasks (weight, volume, volume displacement). During one semester, they were examined over the course material using published Biological Sciences Curriculum Study (BSCS) Blue Version examination questions which were previously classified as requiring either…
