Northshore social studies teacher Rhonda McGee has been selected from more than 500 applicants to participate in the Library of Congress Teaching with Primary Sources Summer Teacher Institute, June 17-21, in Washington, D.C. Participants will work with Library of Congress education specialists and subject-matter experts to learn effective practices for using primary sources in the classroom, while exploring some of the millions of digitized historical artifacts and documents available on the library’s Web site. Teaching with primary sources is a powerful way to help students become engaged learners, ask probing questions, build critical-thinking skills and construct new knowledge. Primary sources are the raw materials of history — original documents and objects that were created at the time under study. The Library of Congress is the nation’s oldest federal cultural institution and the world’s largest library. It serves as the research arm of Congress and is recognized as the national library of the United States.
