Museums offer teachers professional development opportunities to learn how to utilize primary source materials in their classrooms. Workshops and institutes at museums like the Walters Art Museum, Baltimore Museum of Art, Library of Congress, and Smithsonian American Art Museum teach teachers how to access and analyze artifacts, documents, and artworks. Teachers develop lesson plans using museum resources and test them out in their classrooms. Technology like websites, images, videos, and podcasts are used to enhance lessons and student projects.
