Drawing from the information presented at a conference sponsored by the Harvard Graduate School of Education and the Mid-Atlantic Regional Technology in Education Consortium, educators, researchers, and policymakers translate theory into practice to provide a hands-on resource that describes different models for scaling up success. This resource includes illustrative examples of best practices that are grounded in real-life case studies of technology-based educational innovation, from networking a failing school district in New Jersey to using computer visualization to teach scientific inquiry in Chicago. The book demonstrates how lessons learned from technology-based educational innovation can be applied to other school improvement efforts. Following a Foreword (Ellen Condliffe Lagemann) and Preface, the book includes eleven chapters: (1) Moving from Successful Local Practice to Effective State Policy: Lessons from Union City (Fred Carrigg, Margaret Honey, and Ron Thorpe); (2) Dewey Goes Digital: Scaling Up Constructivist Pedagogies and the Promise of New Technologies (Martha Stone Wiske and David Perkins); (3) Adapting Innovations to Particular Contexts of Use: A Collaborative Framework (Barry J. Fishman); (4) Designing for Scalable Educational Improvement: Processes of Inquiry in Practice (Susan R. Goldman); (5) Scaling Up Professional Development in the United Kingdom, Singapore, and Chile (Laurence C. Peters); (6) Technology as Proteus: Digital Infrastructures That Empower Scaling Up (Chris Dede and Robert Nelson); (7) Scaling Up Data Use in Classrooms, Schools, and Districts (Sam Stringfield, Jeffrey C. Wayman, and Mary E. Yakimowski-Srebnick); (8) Foundations for Success in the Great City Schools: Lessons from Some Faster-Improving Districts (Michael Casserly and Jason C. Snipes); (9) Scaling Up Technology-Based Educational Innovations (Barbara Means and William R. Penuel); (10) Critiquing and Improving the Use of Data from High-Stakes Tests with the Aid of Dynamic Statistics Software (Jere Confrey and Katie M. Makar); and (11) Scaling Up Success: A Synthesis of Themes and Insights (Chris Dede and James P. Honan).
