Could great afterschool education become the model for the school day of the future? Schools have requirements that afterschool programs do not. But if afterschool programs build innovative learning experiences in STEM or other content areas that young people gravitate to and even love, the answer to this question should be an emphatic “Yes.” The boundaries between afterschool and school are already softening. Many schools share a focus on exploration, hands-on activities and group work, and afterschool programs often take responsibility for enriching academic learning. Can we build a school day that is founded on the idea of the whole child, identity development and the exploration of how the world works? Can that happen in environments that do not constrain students to the inside of buildings? And can students participating in this new, “flexible school” show real academic gains?
