Do teachers innovate? Do they try different pedagogical approaches? Are practices within classrooms and educational organisations changing? And to what extent can change be linked to improvements? A measurement agenda is essential to an innovation and improvement strategy in education. Measuring Innovation in Education offers new perspectives on addressing the need for such measurement. This book's first objective is informative: it gives readers new international comparative information about innovation in education compared to other sectors. And it documents change in a variety of dimensions of school practices between 1999 and 2011. Its second objective is methodological: it assesses two approaches to capturing the extent and type of innovation occurring within and across education systems. The third objective is exploratory: this book showcases a large-scale pilot that presents over 200 measures of innovation in education using existing international data. Last but not least, the fourth objective is prospective: this report proposes new approaches to measuring innovation in education in the future. This book is the beginning of a new journey: it calls for innovations in the field of measurement - and not just of education.
