viiAcknowledgments
This collection is the culmination of a long strand of work. I have been very for-
tunate to work with a group of dedicated teachers and colleagues. I could never
have edited these resources without their intellect and commitment to the work.
My colleague, Cornelia Tierney, and I began thinking about students who
struggle with mathematics ten years ago. Her vision and passion about equity
shaped the projects that we initiated. Our project officer at the National Science
Foundation (NSF), Dr. Larry Scadden, understood and championed our efforts.
The teachers from our Accessible Mathematics project began this work with us. I
am grateful to all of them: Candace Chick, Heather Straughter, Eileen Backus,
Lisa Nierenberg, Karin Olson-Shannon, MaryKay Resnick, Lisa Davis, Andrea
Cerda, Susan Fitzgerald, Leslie Kramer, Karen Ravin, Somchay Edwards, Lauretta
Medley, Michelle Anderson, and Lauren Grace.
More recently, the Educational Research Collaborative at the Technical
Education Research Center (TERC) provided me with funding to pursue publication.
My colleagues, Andee Rubin and Myriam Steinback, have provided unlimited sup-
port and wisdom. I am grateful for and humbled by their generosity. Arusha Hollister
made major contributions to these resources, in writing the workshops and video con-
text pieces and by imparting her knowledge about primary-grade mathematics.
Keith Cochran, Beth Perry-Brown, and Karen Mutch-Jones have given me
thoughtful ideas and comments about several of the essays. Amy Brodesky, Nancy
Horowitz, and Heather Straughter were very astute reviewers. The insights of
Nicole Feret were incredibly valuable in shaping the writing. David Smith lent
his creativity and patience in producing the DVD.
I was also privileged to have a wise group of colleagues from the Professional
Development Study Group. Deborah Schifter generously offered to write the
Foreword, and members of the group read several entries and provided excellent
feedback and encouragement.
Victoria Merecki at Heinemann has provided me with gentle, intelligent
guidance and encouragement throughout.
