To create a clear picture of a personalized learning environment, this article walks us through a day at the Waukesha STEM Academy, a Wisconsin charter school serving about 300 students in grades 6-8. The article follows Cal, a student making the transition from his former traditional school (where every week looked about the same) to a school where he had to learn how to advocate for his own acquisition of knowledge and seek out the resources he needed when he struggled. From messaging his project teammates as he eats breakfast, to meeting with his advisory teacher, to working through his math skills online, to checking in with his literacy facilitator to obtain coaching, Cal shapes his own school day depending on his individual learning needs. Cal understands what, why, and how he should learn--and he is actively invested in making that happen.
