This article describes a school-based professional development project, which established collaboration between two teacher educators and a group of elementary public school teachers. This collaborative project was called “Book in a Bag” (BIB), which was launched this project as a way to promote curriculum integration in classrooms and at the same time to provide a venue for research. The authors used a self-study to collect data. The authors came to understand that the tensions they experienced in the BIB project were evidence of real differences between the discourses of teacher educators and teachers. The authors identified competing discourses of teachers, teacher educators, and partnership, noting paradoxes that focused on discourse-bound knowledge, discourse-driven motivation, and discourse-limited aspirations.
