This three-paper dissertation addresses the manner in which students’ intrinsic motivation to engage in academic tasks changes during the four years of college. The first paper examines the variance of students’ academic motivation during college. The second paper analyzes whether good practices in undergraduate education promote academic motivation, and the third paper seeks to determine whether those good practices benefit certain students more than others. Implications are explored in each paper.

The present study examines the effects of first-year college experiences on undergraduate students' development of altruistic and socially responsible behavior - a critical college outcome that leads to significant public or external benefits and support. Furthermore, this study examines whether the effects of first-year college experiences on altruistic and socially responsible behavior vary between first-generation and non-first-generation students. To guide the study's investigation, human, social, and cultural capital theory are used as conceptual frameworks and college impact models - including Astin's Input-Environment-Outcome model, Pascarella's General Model for Assessing Change model, and Weidman's model of undergraduate socialization - serve as a theoretical guide. Using longitudinal, pretest-posttest data from the Wabash National Study of Liberal Arts Education, ordinary least squares regressions are utilized to estimate the effects of the college experience on first-year students' altruism and social responsibility. Findings from these analyses suggest that a number of first-year college experiences and participation in vetted good practices significantly contribute to undergraduates' development of altruistic and socially responsible behavior.

This three-manuscript formatted dissertation interrogated the effectiveness of high-impact educational practices for marginalized students through the use of critical quantitative inquiry. The first empirical manuscript used data from the Wabash National Study of Liberal Arts education to explore the role of race and class on students’ engagement in and effects from high-impact practices. Findings from this manuscript suggest significant differences in academic motivation change over the first year of college when race and class were examined together, while no differences when just class was examined. The second empirical manuscript used data from the National Study of LGBTQ Student Success to examine the intersections of environment and participation in and effect from high-impact practices for lesbian, gay, bisexual, and queer (LGBQ+) students. Findings from this manuscript suggested that students’ perceptions of overall support and their relations with instructors mediated the influence that participation in high-impact practices had on students’ academic development. Finally, the third main manuscript considered the utility of critical quantitative inquiry and ways researchers can combine critical theory into quantitative research.

This research is a detailed look at intercultural competence, an issue showing escalating importance in today's higher education and the society at large. In this study, intercultural competence was defined in light of the concept of culture and the contact hypothesis. Person-environment interaction theory and college impact theories were incorporated as theoretical foundations for the operationalization of this research. The development of students' intercultural competence was examined from two perspectives--intercultural competence is viewed both as a desirable outcome of college education and as an active environment component that exerts important influence on students' self-reported gains. Findings of this study evidenced that a variety of college activities, especially those emphasizing cooperative and associated learning, play important role in students' intercultural competence development. Intercultural competence, in turn, has substantially positive effect in student gains in multiple realms. The intrinsic influences of student characteristics were also examined. In the end, previous research was drawn upon to scrutinize the findings of this study. Implications to future practice and policy as well as the values and limitations of this study were also presented. / Ph. D.
