| Summary: | This thesis consists of a single subject multiple baseline study of a math intervention for students with behavioral challenges. Students with behavioral challenges were given instruction using a concrete, representational, abstract (CRA) sequence in Algebra problems requiring transformations on both sides of the equation. This study examined maintenance of those skills. Results indicate that while accuracy decreased from the post-intervention to maintenance phases, scores remained well-above baseline levels indicating that the students retained understanding of the concepts taught. In a social validity survey, participants indicated that they liked the intervention, found it beneficial, and sometimes use it in their classes. === text
