The Museum Institute for Teaching Science (MITS) promotes the teaching of participatory, hands-on and minds-on, inquiry-based science, technology, engineering, and mathematics (STEM) at the K-8 grade levels, through collaboration among informal science education institutions. To this end, MITS has developed three programs: a two-week Summer Institute for K-8 teachers taught by museum educators; a quarterly resource publication for K-6 teachers; and three seminars that help museum educators stay up to date on latest methods and education reforms.
