When I reflect on the world of curriculum teaching and learning in the schooling sector over the last twenty years, I see a co-evolving landscape made up of students and their families, their teachers, schools, boards and New Zealand society at large. The components might be the same, but over the 20 years since Tomorrow’s Schools, there has been a process of evolution where the parts have adapted in various ways in response to each other and, over that time together, have created a different landscape. I want to reflect on several themes: our history and where we have come from, and how that affects where we are and where we might go next; the learning that has come from the experience of doing things together; creativity, innovation and emergence of new ideas and new ways around curriculum, learning, teaching and assessment; and most importantly, interdependence between the parts of the system and their co-evolution.
