The mission of Polaris Charter Academy is to educate students to be self-motivated, creative, critical thinkers, with the ultimate goal of shaping life-long learners and citizens with a strong sense of personal and civic responsibility. While on sabbatical in the fall of 2005, three Golden Apple Award winning teachers identified the common thread of their best practices in teaching: learning by doing. Each founder had attributed their success in the classroom to a specific approach focused on participatory, hands-on, project-based learning and in-depth study of compelling topics. So what would it look like if an entire school was focused on this approach? The vision of these award-winning teachers came to fruition when Polaris Charter Academy opening its doors in 2007 as the city’s first Expeditionary Learning school, a comprehensive educational reform model which grew out of a partnership between Harvard University and Outward Bound. PCA opened with grades K through 2nd and now serves 450 students in grades K through 8th. Polaris Charter Academy structures its sciences and social studies curriculum around “learning expeditions.” These in-depth investigations are different from traditional thematic units. Learning expeditions are long-term investigations spanning one or more trimesters that are developed around specific Illinois State Learning Standards. They related to real-world topics or concerns that make learning relevant to students’ lives. Learning expeditions provide a rigorous, stimulating educational experience that requires the application and mastery of a wide range of skills, including conducting research through interviews, surveys, books, and the internet. Students conduct fieldwork, learn from experts, work collaboratively and create authentic, high-quality end products for audiences beyond the classroom. Final products have been featured in the Chicago news, public libraries, organizational education programs, and more.
