Peer reviewedCamacho, Fernando Flores; Cazares, Leticia Gallegos – Science Education, 1998
Illustrates the construction of conceptual models on pressure and flotation using high school students' previous ideas on these concepts. Identifies three models and uses them to analyze students' ideas about physical phenomena and to recognize the inferential structure they use. Contains 28 references. (DDR)

Manhart, Jim J. – 1998
This study investigates gender differences with regard to three factors of scientific literacy. The study involved students (N=772) in Grades 9 and 10. A 100-item multiple choice test based on National Science Education Standards was used to assess scientific literacy while gender differences were explored using analysis of variance procedures.…
