The problem with which this investigation is concerned is that of determining the differential impact of an introductory economics course on the liberalism/conservatism of students, as compared to an introductory course in sociology or psychology. In addition, the study seeks to determine whether a significant relationship exists between a course in microeconomics and student conservatism. The source of data is the pre- and posttest class means of the scores on the Rokeach Opinionation Scale, measuring liberalism/conservatism. Chapter Five contains the conclusion that there is a significant difference between postmean scores on liberalism/conservatism of the students in economics and those in sociology or psychology. Also, an introductory course in microeconomics produces significantly different mean gains in student conservatism, as measured by the Opinionation Scale/compared to mean gains in an introductory course in sociology or psychology. A nonhypothesized relationship emerged between teacher attitude and student posttest mean scores on the Opinionation Scale.
