This project started out small and quickly became too ambitious to carry out alone. Many people are responsible, in large and small ways, for the completion of the project. For this, I owe them a debt of gratitude and public acknowledgement. I thank my committee members, each of whom has served as an excellent professional role model: # Davwf jfw&rg#-who generously collaborated; tirelessly read draft after draft, commenting on some things and kindly leaving others for later (in order to help me retain my sanity); and taught me to withhold judgment. I simply could not ask for a better or more supportive mentor and colleague. » Dorof&y Wmaor-who enthusiastically supported me in my research and responded positively to the place I ended up. « MicAagf MgwkZfo»-who treated me like a colleague, found financial support for the project, and provided the best example of what a supervisor could be. # Mary ffwixz-who kindly allowed me the opportunity to serve on the Assessment Subcommittee and who gently provided much needed feedback about my surveys. # Do» Dowg&za-whose good humor, humility, and kind and encouraging remarks do not go unnoticed or appreciated. I express appreciation for the support of the Howard Shapiro, Corly Brooke, and Doug Gruenwald, who generously funded three years of assessment of linked English learning community courses, demonstrating their commitment to excellence and constant improvement. I gratefully thank my friends and colleagues who collected and coded data, read drafts of my work, brought me food, formatted my figures and headings, taught me how to get rater reliability, encouraged me to take up yoga, and patiently listened to me talk about this project for three years:
