The document discusses liberating classrooms through technology choice by rethinking the traditional structure of classrooms. It suggests that 1) rethinking the rigid division of time into learning vs non-learning, 2) eliminating divisions between students by age and content by subject, and 3) using technology and spatial environment choices to encourage crossing boundaries and sharing can help create more flexible learning spaces. It asks a series of questions about how the classroom space can be designed to encourage collaboration, consolidation of learning, and choice to enable every learner's comfort.
