The resource teacher's role in providing inservice training to regular educators is examined. The paper then describes an Action Plan Approach in which regular education teachers and the resource room teacher jointly identify problems commonly associated with mainstreaming and utilize combined efforts to resolve the problem. The advantages to the Action Plan Approach include shared responsibilities, vested interest by all involved, and developed materials/strategies that facilitate successful mainstreaming. The approach is broken down according to problem identification processes, goal specifications, and additional resources. (Author/CL)
