This case study explores the immediate impact of LGB-themed instruction by examining graduate education students’ written reflections following a guest lecture on LGB-related educational issues. The participants in this study were the instructor who was a heterosexual woman, two guest speakers who were two gay men, and 18 credentialed, master’s degree education students. The results of the current study indicate that teachers are more likely to establish and implement inclusive policies and practices in their classrooms in response to LGB-themed instruction.
