Students with previous Introductory Physical Science (IPS) experience performed no better on assessments of achievement and critical thinking after completing a BSCS green version course than did those with a non-IPS ninth grade science course. (AL)

Maintains that present high school chemistry courses cause students to lose their enthusiasm for science because emphasis is on mastery of the principles of chemistry rather than on forming positive attitudes. Recommends that content be relevant, and suggests format for such an approach. (PR)

Compares first year performance of science and engineering university students with and without PSSC Physics in high school. PSSC students, particularly those of high ability, performed better. (AL)

Reports on study to determine whether pupil-inquiry method is superior to a teacher-directed method of teaching Time, Space, and Matter to eighth graders. Results indicate inquiry method more effective in developing understanding of the methods of science, but shows no difference for critical thinking and learning of science facts and principles.…

Reports affective changes of students studying PSSC Physics in grades 11 and 12. Students lost interest in physics, viewed scientists as more abnormal, but increased in acceptance of a non-authoritarian teaching situation. (AL)

Demonstrations involving the preparation of sols, protective colloids, electrical properties of sols, and the tyndall cone are presented. (RR)

Presents a teaching model which utilizes a multimedia approach to facilitate individualized instruction in a physics unit for high school students. The model includes objectives, activities, check points and satellite activities. Reports favorable reactions from both students and teachers who have used this instructional approach.
