This paper, on a 1988-89 study of 219 undergraduates, addresses issues of cognitive development, learning style, and attitudes toward social diversity and social justice. A parallel study was conducted in spring/fall 1989 with subsequent changes noted. The table of contents presents the following sections: (1) "Background and Educational Context"; (2) "Conceptual Framework: Social Cognitive Development"; and (3) "Methodology and Discussion of Findings: Stage One of Research." Pre- and post-test results were analyzed for four assessment instruments: (1) Baxter-Magolda's Measure of Epistemological Reflection (MER); (2) Rest's Defining Issues Test (DIT); (3) Hudson and Ricketts' Index of Homophobia (IMT); and (4) Kolb's Learning Style Inventory (LSI). Numerous tables, figures, and illustrative diagrams support the narrative. An extensive bibliography is included. (EH)
