Describes the use of Marchant 1016PR with a magnetic tape reader, Monroe 1665 with a punchcard reader, and Hewlett-Packard 9820A with an X-Y plotter to conduct introductory physics laboratory programs. Indicates that the course allows more physics to be done in the same amount of time. (CC)

Describes the use of a simulation lesson which is written in TUTOR language for the PLATO computer for the purpose of separating a mixture of four ions with known identity. Indicates that students have more freedom to experiment than in laboratories in other traditional computer-assisted programs. (CC)

Describes the use of two polarizing lenses, a yellow filter, an oatmeal bos, a piece of cardboard, a 1,000 ml beaker, and an overhead projector to demonstrate compound optical activity to large classes. Indicates the presence of an accuracy within 1-2 degrees of usually acceptable data. (CC)

Data from two studies at Gladstone High School in California support the assumption that daily writing and daily correction and grading based exclusively on mechanics do improve a student's ability to write more correctly by eliminating common errors. (Author)

Describes the errors in the sugar-cube experiment related to radioactivity as described in Project Physics course. The discussion considers some of the steps overlooked in the experiment and generalizes the theory beyond the sugar-cube stage. (PS)

This bird (the Toucan) is the perfect symbol for a multimedia, multiethnic, multiage, people-oriented school, the Grant School, Bridgeway Project, in Waterloo, Iowa. (Editor/CB)

Describes apparatus which can be constructed to allow students to experiment and collect data for understanding various aspects of simple motion of objects. Detailed instructions are given. (PS)
