This study explored undergraduate students' changes in attitudes toward marriage equality in an introductory family science course. Students enrolled in the course were exposed to teaching activities centered largely around prejudice and discrimination to examine their effectiveness in facilitating the development of more positive attitudes toward marriage quality. The results of quantitative analyses revealed that substantial numbers of students became more supportive of marriage equality over time in this course. Qualitative analyses of written open-ended student responses utilizing the constant comparative method resulted in three emergent themes: support of marriage equality, increased understanding of marriage equality, and opposition to marriage equality. Collectively, the findings of this exploratory study indicate that the teaching method utilized was effective in fostering the development of more positive attitudes toward marriage equality. Implications for future research, replication, and adaptation in other disciplines are discussed.
