This document discusses the theory and practice of teaching and learning with tablet computers. It outlines how 1:1 computing represents a disruptive change in the learning environment. While some 1:1 computing initiatives have failed, others show promise when the whole school adopts digital technologies and changes its pedagogical approach. The document proposes five scenarios for effective tablet-based classrooms, including flipped classroom, inquiry-based learning, project-based learning, problem-based learning, and game-based learning.
