Changes in Understanding of the Nature of Science and in Critical Thinking Resulting From Two Different Physical Science Courses.
Whitten, Maurice Mason
Reported is an investigation to determine if changes in college students' understanding of the nature of science and in critical thinking result from modifying a "traditional," general education, laboratory, physical science course. The criterion instruments were the Test on Understanding Science (TOUS), Form W; the Wisconsin Inventory of Science Processes (WISP); and the Cornell Critical Thinking Test, Level Z. The experimental group consisted of all students (190) who completed the courses in physical science required of all elementary (K-6) education majors in their freshmen year, 1969-70. The control group, 144 students, completed the course (unmodified), in 1968-69. Scores on the CEEB Scholastic Aptitude Test were used for statistical controls. Analyses of variance showed the only significant gain (.05 level) made by the control group was on TOUS - Part I, Understanding the Scientific Enterprise. The experimental group made gains (.001 level) with TOUS - Part I, TOUS - Part III, TOUS - Total, and WISP. No significant differences were seen between instructors in producing changes on tests. Laboratory exercises made an important contribution to the TOUS gain scores for the experimental group. (Author/EB)
