Directors of a program to increase the number of black and Spanish-speaking students enrolled in physics courses explain its organization and their conclusions. (DS)

Discusses a relatively simple technique for demonstrating multiple beam interferometry. The technique can be applied to measuring (1) radii of curvature of lenses, (2) surface finish of glass, and (3) differential phase change on reflection. Microtopographies, modulated fringe systems and opaque objects may also be observed by this technique.…

Reports on the Moline Project, a two-year unified chemistry and physics course for high-ability students. Parallel programs in physics were developed for the other students. These programs have succeeded in increasing student enrollment in physics from 4.6 percent of the student population in 1962 to 10.6 percent in 1969. (LC)

Analyzes effects of different student backgrounds on success in an introductory college biology class. Students with BSCS Yellow Version high school courses were consistently superior to other groups. Results consistent with Ausubel's Theory of learning. (AL)

Students who solved problems individually or in small informal groups understand science and scientists better than those who solved the same problems (based on BSCS Blue Version) as a class group. (AA)
