I've used this site in my Geography, World History, and AP World History courses. The East Asian Institute at Columbia University contains a wealth of resources for both secondary and elementary school teachers. The site supports the study of East Asia through various topics: Geography, Literature, Art, Religion, World History- with World History being the most thoroughly covered. The site provides four in-depth teaching modules (which would be most useful for secondary classrooms), and a host of lesson plans, video resources, maps, and Document Based Questions (DBQs). In truth, some of the documents and texts provided are too dense for non-AP or honors-level high school students. If your class has a large population of English Learners, I would highly suggest modifying them before using them with your students. However the videos, visuals, and maps are ready to use. One of my personal favorite features is the "Resources by Time Period" section of the site. I use this feature with my AP students to review global trends and compare empires throughout history. The feature is particularly helpful, as it allows students to review concepts and compare events across Asia across time periods that are exactly aligned to the eras of the AP World History Curriculum.
