How might we know whether our schools or system are set up to optimise learning? How can we find out whether we are getting the most from technology? How can we evaluate our innovation or think through whether our change initiative will bring about its desired results? Teachers and educational leaders who grapple with such questions will find this handbook an invaluable resource. It draws on extensive reports and materials compiled over a decade by the OECD in its Innovative Learning Environments (ILE) project. Its four chapters--The learning principles; The innovative learning environment framework; Learning leadership and evaluative thinking; and Transformation and change--each contain a concise, non-technical overview introduction followed by a set of tools. The handbook makes good the ILE ambition not just to analyse change but to offer practical help to those around the world determined to innovate their schools and systems.
