Through the use of data, attendees will investigate ways that administrators and systems can provide support through effective professional learning activities, scheduling, class composition, co-teaching partnerships, and observation tools. Participants will discuss ways to establish and grow school and district co-teaching programs in order to improve student math achievement for all students. Now entering the third year of implementation, the Jordan School District Special Education department has actively supported a co-teaching model for mathematics instruction in secondary schools; these are their stories.
