Teaching architecture as general education serves various purposes. Studying familiar buildings may become an intriguing introduction to liberal arts, including art, history, and natural and social sciences. Students can learn critical thinking, problem-solving, and interdisciplinary communication when studying architecture, which are vital higher education goals nowadays. Architecture students and other majors studying together may also improve the future mutual understanding between architects and clients. Housing and living environments are so essential that various efforts are made to teach them to children. Still, primary and secondary school teachers need more time, experience, or confidence to teach such a vast and technical subject. Architecture professors and practitioners can take it over in higher education. To examine the feasibility of this proposal, the author gave a 100-min online experimental lecture on introductory architecture to 1600 first-year students in different majors and conducted a quantitative text analysis on post-learning evaluation. The result proves that practical topics such as safety and environmental preservation interested students regardless of the major. However, a questionnaire survey revealed that students are much less interested in their living environment than in food and clothing. We ought to think about how to make them aware of the importance of this subject.
