Managing a distributive education (DE) laboratory is a challenge. The laboratory is the simulated training station, with the instructor taking on the role of employer, managing student activities and learning. One tool to be utilized in managing a DE laboratory is a training plan. This article discusses the need for student training plans and the…

Media is used as a supplement in a science education program based on the inquiry method. Students work in small groups and rotate from station to station. (STS)

Actin and myosin have now been demonstrated to be important constituents of many eukaryotic cells. Their role is primarily that of a contractile system underlying all aspects of cellular motility. Described here is a simple experimental system to demonstrate quantitatively aspects of motility and its regulation in a slime mold. (Author/MA)
