Mathematical problem solving has been identified as one foundational area of mathematics for all students but is an area of weakness for students with disabilities. This investigation sought to determine the effects of peer-delivered schema-based instruction on the mathematical problem solving of the change problem type with four middle school students with extensive support needs using a single-case multiple-probe-across-participants design. We also wanted to determine if same-age peer tutors who received behavior skills training could deliver the academic instruction with fidelity. Students and peer tutors were representative of diverse backgrounds. Results showed a functional relation between peer-delivered modified schema-based instruction and students' acquisition and maintenance of mathematical word problem--solving skills, and strong effect sizes were found. Peer tutors were able to provide instruction with high levels of fidelity across the study. Social validity data showed that all participants benefited from the peer-delivered instruction.

This study evaluated an intervention developed through an Institute of Education Sciences-funded Goal 2 research project to teach students with moderate intellectual disability (moderate ID) to solve addition and subtraction word problems. The intervention involved modified schema-based instruction that embedded effective practices (e.g., pictorial task analysis, graphic organizers, systematic prompting with feedback) for teaching mathematics skills to students with moderate ID. The dependent variables included steps performed correctly on a problem solving task analysis, number of problems solved, problem type discrimination, and generalization of problem solving skills. Results of a multiple probe across student dyads design indicated a functional relation between three dependent variables and the intervention. Upon completion of the intervention, all eight participants with moderate ID correctly followed the task analysis, discriminated problem types, and solved word problems. Key discussion items include feasibility of teaching problem solving skills, types of modifications needed, and the generality of these skills to novel formats.

Mathematical problem solving is necessary in many facets of everyday life, yet little research exists on how to teach students with more severe disabilities higher order mathematics like problem solving. Using a multiple probe across participants design, three middle school students with moderate intellectual disability (ID) were taught to solve video-simulation real-world mathematical problems by finger counting using video prompting (VP) in conjunction with systematic instruction (e.g., least intrusive prompting) with error correction and feedback. The simulated videos covered a variety of thematic units (i.e., pet store, grocery store, household chores, sporting goods store, outside chores, and thrift store) students may encounter in their everyday lives. The results of this study demonstrated a functional relation between VP and participants' mathematical problem-solving skills. Findings from this study provide several implications for practice and research for using video-based interventions to teach mathematical problem solving to students with moderate ID.

Literacy is an important skill for accessing all academic content areas, and there has been an increased focus on using a variety of assistive technology (AT) to support the acquisition of literacy skills for students with severe disabilities. Literacy also provides these students with skills to increase community participation, with independence, with skills to make individual choices, and with opportunities for potential employment. Portable technology such as an iPad2® can be used to enhance literacy skills for students with severe disabilities in elementary school. A typical way to teach literacy to this population is through the use of a shared story. Although systematic instruction has proven to be an effective teaching strategy, the generality of the literacy skills usually has not been the focus of the training. In this study, five students with severe disabilities (IQ below 55, range in age 7-11 years, grade range 2nd-6th grades) were taught to generalize literacy skills via multiple exemplar training. A multiple probe design across participants demonstrated a functional relation between student responding and the intervention. Extension of what we currently know, limitations, and future research are discussed.
