For many teachers, primary sources serve as a new frontier. Primary sources sit at the frontier of content because they offer insights into stories of the past that might be unknown. Primary sources also sit at the frontier of pedagogy because teaching with primary sources such as documents, oral histories, cartoons, photographs, and paintings, requires innovative strategies to promote higher order thinking with these different source types. In this session, teachers will learn how to locate primary sources that uncover stories of the past while also learning engaging new strategies for teaching with them.
