The Teach-In is a program sponsored by the Institute for the American Constitutional Heritage which brings some of the world's best teachers to the University of Oklahoma's main campus for a full day of lectures on a particular topic. The Teach-In has experienced tremendous growth since its kickoff in 2012, with attendance now regularly surpassing 2,000 people.
The IACH's signature event takes place each spring and comes at no cost to the public. Video lectures from each Teach-In can be found here and at teachin.ou.edu. Additional information about past speakers can also be found at teachin.ou.edu.
