Response to Commentaries

摘要

In responding to the thoughtful commentaries on our article, we focus on two important issues raised by most of the reviewers: (a) the curricular dependence of the proposed learning progression and the daunting (twin) challenges of bringing about changes in curriculum and assessment and consolidating and validating the proposed learning progression, and (b) the need for further research and development of a wide variety of sorts. We agree they are major challenges but see them as opportunities as well: opportunities to use research on children's learning to inform curriculum and assessment much more than is currently the case.
