At a time of rapid technological change and professional specialization, we can easily forget that the most important mission of schools and universities is to offer inspiring and horizon-expanding teaching to the next generation. Survey courses play a particularly important role as they open the world to students and help give them critical purchase on their own landscapes and lives. A good survey course balances breadth with depth, but in an ever-expanding world that balance can be lost, meaning that the problem is not just how to teach students, but how to prepare teachers. The GAHTC’s mission is to provide cross-disciplinary, teacher-to-teacher exchanges of ideas and material, in order to energize and promote the teaching of all periods of global architectural history, especially at the survey level. Importantly, we support teachers in the classroom as an integral part of education.
