An investigation of introductory physical science using the test of science process

The hypotheses tested were that there would be differentially, significant improvement in scores on the Test of Science Processes (TSP) for four homogeneous divisions of an eight grade class during the period they studied the first five chapters of Introductory Physical Science (IPS). Results indicated significant improvement in at least one process subscore for each division of the class. A hierarchy of processes was suggested as a topic for further study.
