Despite originally being almost exclusively focused on the school context, the National Science Education Standards (NSES) emerged as an amazingly relevant document for the informal context as well. All four of the Standards—Teaching Standards, Content and Inquiry Standards, Professional Development Standards and Assessment Standards—can, should, and as the chapters in this volume clearly attest, have been adapted for use in and by informal education institutions. The importance of debate and discussion, collaborative and shared responsibility for learning and data-based inquiries, and an emphasis on process over content permeate the chapters.
