Determined that the majority of 299 preservice teachers did not use formal reasoning patterns when they attempted to solve a variety of problems. Results obtained for controlling variables and for proportional, probabilistic, correlational, and combinatorial reasoning are discussed with implications for middle/junior high school science teaching.…

Seventh-grade students attended a weekend "camp-out" in which local scientists and college educators were used to enrich students' learning. Information on planning the camp-out and an annotated schedule of events are presented. (JN)

Compared the performance of teachers and students on the Field Experiences Achievement Test with results obtained from seventh-grade students who took the FEAT during its development and validation. Results indicate that tests developed for student use may also be used in inservice teacher education programs. (JN)

Describes "Experiments in Chemistry," in which experiments are performed using software and hardware interfaced to the Apple microcomputer's game paddle port. Experiments include temperature, pH electrode, and EMF (cell potential determinations, oxidation-reduction titrations, and precipitation titrations) investigations. (JN)

Indicates that present curricula are not preparing citizens to deal with critical social issues, in particular, those related to the environment, energy, food supply, and population problems. Offers 10 suggestions to help remedy the situation. (JN)
