I also want to thank the graduate student colleagues with whom I discussed this research many, many times over the years. I could not have done this without Jason Elliott, Jochen “Je77” Rick, and the students in the Electronic Learning Communities (ELC) and Learning Sciences and Technologies (LST) research groups. Thank you for always being there for me—whether to challenge my research ideas or simply to let me vent. You have all been wonderful to work with.
My dissertation committee was also indispensable: Mark Guzdial, Janet Kolodner, Judy Olson, and Colin Potts. Mark, thanks for helping me translate my ideas into words that make sense. Janet, thank you for pushing me to achieve more, even when I didn’t want to hear the feedback. Judy, thanks for pushing me toward a deeper methodological understanding. Colin, thank you for all of your help as I conducted the CS 4001 study.
I want to acknowledge the staff of the GVU Center for their support through the years. Your unceasing hard work behind the scenes has enabled everything that I have done. Without your help, this book would not be possible.
Without the individuals and companies that have provided me with financial support, it would have been much harder to get to this point. Study 1 was funded by an IBM Fellowship. Special thanks to Wendy Kellogg and Tom Erickson from IBM for their support. Study 2 was funded by a donation from Pitney Bowes. Special thanks to Austin Henderson and Jim Euchner from Pitney Bowes for this support.
