Presents comments by classroom teachers on courseware for science teaching. Topics covered include astronomy, the heart, sound, geology, physiology, and glacial landforms. Specifications pertaining to equipment needed, availability, and cost are provided. (Author/RT)

Concentrates on the semiempirical methods MINDO/3, MNDO, and AMI available in the program AMPAC from the Quantum Chemistry Program Exchange at Indiana University. Uses charged ions in the teaching of computational chemistry. Finds that semiempirical methods are accurate enough for the general use of the bench chemist. (MVL)

Examines whether participation in physical experiments together with social interaction with adults and school-mates favor the development of causal knowledge and the understanding of a complex physical subject. Concludes that the treatments can lead students to give up pre-causal explanations and to resort to physical ones. (Author/YP)

Identifies the determinants of female junior high school students' intentions to enroll in elective physical science courses in high school using the theory of the Reasoned Action model. Finds that the intentions were a function of both attitude toward performing the behavior and subjective norms. (Author/YP)
