This study was designed to determine if an adapted version of Physical Science for Nonscience Students (PSNS), a physical science course used for nonscience majors in college, significantly contributes to an understanding of the scientific enterprise, positive attitudes toward science and scientists, and knowledge of solid matter and the techniques for its investigation. Four groups of 23 students each made up the sample. The Solomon Four-Group Design was used. Three instruments were administered as pretests and posttests to the Experimental Group. Control Group 1 was tested but did not receive treatment. Control Group 2 was given the treatment and tested only at the end of the 14-week period; Control Group 3 received no treatment, but was tested in the same way. Only the Experimental Group and Group 2 had any formal instruction in science, and none had any math courses during this period. Treatment consisted of the Adapted PSNS Course. Students were expected to do science rather than just learn about science. The major difference between this course and the original was one of length, one year as opposed to one trimester. From data analyses it was concluded that the course, as taught, was effective. (Author/EB)
