Dr. Scott is conducting a study of the effectiveness of a new strategy for teaching writing to eighth graders in inclusive classrooms. His study population consists of two middle schools in the same district. Schools are randomly assigned for implementation into either intervention or control. He administers a test of written language to all students. However, Dr. Scott teaches the new strategy to students in one school but uses a traditional approach to teaching writing in the second school. He again tests students and compares results. What research approach is he using?

▸ Progress monitoring

▸ Error analysis

▸ Single-case design

▸ Randomized controlled trials
