The document discusses the creation of intentional learning spaces at Hillbrook School that are designed based on affordance theory. The school's Idea Lab was created as a prototype learning space that encourages collaboration, movement, and student ownership through its use of rolling whiteboards, folding tables, lack of front of the room, and other design features. The goal was to create a learning environment that supports 21st century skills like critical thinking and problem solving. Evaluation of the Idea Lab's impact will involve collecting data on student engagement and learning through observations, surveys and other methods. The school plans to introduce aspects of the Idea Lab model to other classrooms and share results with other schools.
