During two weeks of July, 2012 twenty NCTA teachers lived in Hangzhou, China as participants in NCTA's first summer residential program. They were based at Zhejiang University attending a variety of classes, participating in field trips, and exploring the city. The end product of this experience was either a series of discrete lesson plans or a complete teaching unit which, when possible and appropriate, included components based on the Hangzhou experience. These teachers worked primarily at the secondary level and represented ten states, covering both the East and West Coasts as well as the Mid-West. The results of their summer experience can be accessed below in the "Supplemental Materials" section, which will link to materials created by these teachers.
