division curriculum and instruction. Conclusion

Though we are only one year into this three year project, findings suggest positive changes to teacher content and practice, as well as, administrative supports that will enhance mathematics instruction in the schools. By simultaneously working with teachers and administrators, this project hopes to build a school- wide, collaborative effort for deepening teacher understanding of mathematics content and pedagogical strategies. We believe this project adds to the existing knowledge base on effective professional development models for working with middle school teachers and administrators within schools and across the school division. The results of the first year of our project reveal that professional development of this type does have a positive impact on teachers and their students. We encourage mathematics teacher leaders, school administrators, mathematics coaches to engage teachers in similar activities in the school buildings in which they work.
