The ambiguity and openness of works of art makes them wonderful objects for critical analysis and reasoning. Teachers and art lovers will enjoy this free online professional development course from the National Gallery of Art (previously featured in the 03-27-2020 edition of the Scout Report). Adapted from the museum's professional development programs for teachers, Teaching Critical Thinking through Art prepares educators to use artworks to help their students develop and strengthen critical thinking skills. In five lessons, educators will learn how to facilitate classroom conversations about art, encourage learners of all levels to use evidence-based reasoning, and integrate online teaching resources from the National Gallery of Art into lesson plans. Even non-educators will want to take advantage of the opportunity to explore and think critically about the featured works of art. The course can be completed in three ways: directly on the page linked above, through EdX (linked on the same page), or in a series of YouTube videos (linked under "Watch and Listen" in the menu on the left side of the page). The National Gallery of Art, located on the National Mall in Washington, D.C., is a national center of art, education, and culture with a collection of more than 150,000 works of art.
