The Gateway Writing Project (GWP) at the University of Misouri-Saint Louis is described in this report. It is the St. Louis site of the National Writing Project founded at the University of California, Berkeley to meet the critical need for highly skilled teachers of writing. GWP has helped students at all levels learn to write by providng specialized training for their teachers. From 1984 to 1987, it developed a model integrating computers into a program of staff development, action research, and support for instructional change in writing. Staff development has consisted of summer institutes for teachers, 1-day seminars for administrators, and a variety of credit courses and noncredit workshops. Action research has included case studies, text analyses, and participant observation in the classrooms of trained teachers. Support has focused on four pilot schools where teachers and administrators formed writing improvement teams. The project's impact has been far-reaching and rapid, including five curriculum guides to teaching writing with computers, dozens of articles, and program replication at an inner-city teacher's college. Information has been shared with educators statewide and internationally. Because of this project, the university can now offer valid, classroom based information to schools and teachers planning computer equipped writing programs.
