Classrooms in the 21st Century No More Rows. The days of desks arranged in straight rows facing the teacher and the blackboard are over. Classrooms in the 21st century invite learners and educators alike to come in and delve into deep and authentic learning. They are comfortably-appointed — like a family room — and rich in learning materials and resources. In this sort of environment, there are all kinds of nooks and crannies to meet a variety of learning need, including areas for group work and discussions, areas for creating, places to study and think alone, and whenever possible, outdoor spaces to breathe in fresh air and actively play.
