Discusses difficulties of learning and teaching science at the secondary school level. Highlights include the nature of science concepts; multilevel thought; the use of scientific experiments; language problems; students' learning processes; and an information processing model that can be used to guide thinking and research in this area. (10…

Conducted classroom observations to determine students' understanding of the nature of science and the intentionality of experiments. Topics discussed include: does science seek to explain, using models, proving that the theoretical explanation is correct, and discussions of different interpretations. Concludes that most students in the 14-16 age…

If science education is to be related as closely as possible to science, then Thought Experiments (TEs) must play an appropriate part. Presents a typology of TEs with examples drawn from the history of physics and addresses their various uses in bringing about students' conceptual development. Finds appropriate use of TEs is lacking in physics…

Describes a prototype interactive science catalog for children that will have three interfaces: a subject-oriented browsing search, a search tied directly to science simulations, and an author/title/subject keyword searchable interface. Research plans include examinations of children's abilities to formulate and implement searchable queries and…
