Personal tablet style devices are projected to become a staple in classroom settings due to their increasing capabilities, improving a_ordability, portability, weight and ability to hold the texts a student might need. However, these devices are not islands of computing and storage and instead represent a display ecosystem which can support new forms of interaction, teaching, planning, coordination and hence learning. In this paper, we describe CSCT - Computer Supported Cooperative Teaching, a system to allow teachers in a one-tablet-per-child classroom to gain valuable feedback from their students, making the classroom more e_ective and allowing teachers to create lesson plans that more accurately reects the learners abilities. We describe the design and motivation for such a system.
