Traditional architectural history teaching demonstrates significant limitations in spatial perception development, knowledge acquisition methods, and student motivation. This study proposed three teaching reform strategies to address these challenges: Virtual Reality (VR) technology introduction to enhance architectural comprehension, mixed teaching model adoption to improve knowledge accessibility, and task-driven teaching methods implementation to increase learning enthusiasm. Researchers constructed a teaching framework of "pre-class independent preview, in-class interactive exploration, and post-class consolidation" using the "Athenian Acropolis" chapter from "Ancient Foreign Architectural History" as a case study. The study compared VR-integrated mixed teaching with traditional methods through quasi-experimental research with 60 first-year architecture undergraduates from two classes. Mann-Whitney U tests revealed the experimental group significantly outperformed the control group in architectural comprehension (U=205.000, p<0.01), knowledge accessibility (U=89.000, p<0.01), and learning enthusiasm (U=150.500, p<0.01). These results confirm that this teaching model effectively enhances student understanding of complex architectural concepts, facilitates more efficient knowledge resource access, and improves learning initiative.
