Grade 8 students using the Introductory Physical Science course improved their scores on a test of science processes (observing, comparing, classifying, quantifying, etc.) after studying the first five chapters of the materials. Some evidence supporting a hierarchy of process skills is reported. (AL)

Examples are given of activities that begin with the classification of objects into sets and lead to concepts and activities in other branches of mathematics, in language arts, and in science. (DT)

This column discusses problems involving a paper folding game for bicimals, the sum of exterior angles of polygons and polyhedra, solving quadratic equations in finite arithmetics, nomograms, and cube folding patterns. (DT)

Describes material used in a first semester introductory physics laboratory for nonscience majors. The computer is used for data manipulation and in some cases, computer programs allow simulation of experiments with the possibility of altering values of parameters or experimental details.

There were no significant differences in achievement between students using an earth science laboratory block with or without teacher direction. (AL)
