It was predicted that high-scoring students would be better able to answer correctly questions directed at knowledge of principles and that this superior knowledge would result in better performance on questions on trivial materials as well. (Author/KM)

This study was designed to identify those science concepts and mathematical skills that may be the source of student difficulty in learning chemistry as developed by the Chemical Education Materials Study (CHEMS). The instruments utilized were four Achievement Tests prepared by CHEMS. Each test item was analyzed to determine the concepts and/or…

Reported is a study to compare two seventh-grade science programs with respect to students' attitudes toward science, science process skills, and critical thinking ability. The study population included two teachers and their eight classes. Each teacher had two experimental and two control groups. Remmers'"Attitude Toward Any School…

Reported is a study involving a modification of the mastery learning technique designed to determine the effects of general remediation on the achievement of the mole concept by 99 ninth-grade physical science students. Results of one way analysis of covariance did not indicate a significant difference in mean scores between treatments. (DS)

This bibliography, made up of approximately 350 entries concerned with many aspects of problem solving and concept formation in young children, has been designed for use by people primarily involved in experimental research in these areas of child development. Entries include experimental journal articles, conference papers, unpublished research…
