Mary's Sp.Ed. co-teacher never makes modifications for her language arts students when that period comes to her. Mary has been to the Sp.Ed. co-teacher to specifically ask for help for making modifications for her special needs students. When emailing the Sp.Ed. co-teacher the lesson plan for the upcoming week, Mary specifically asked the co-teacher what days she would like to teach. Instead of helping Mary out with the "co-teaching" and modifications, the Sp.Ed. co-teacher only points out mistakes that Mary has made on the lesson plan. When the co-teacher has been in Mary's room, she offers no help with the teaching for instruction and only helps one particular group during differentiated group activities. Mary has been to her administrator and the Sp.Ed. director about the Sp.Ed. co-teacher, and they suggested meeting with the co-teacher on a weekly basis to set up who would teach what and when. Since the Sp.Ed. co-teacher has not made any efforts to help Mary, what suggestions do you offer Mary to try to get the two teachers on the same page in sharing teaching responsibilities?
