Research in special education has yielded beneficial outcomes for students with disabilities as well as typical achieving students. The authors provide examples of the valuable knowledge special education research has generated, including the elements of response to intervention (e.g., screening and progress monitoring), instructional practices such as systematic instruction and feedback, and intensive interventions designed to meet the specific learning needs of students with disabilities. They present the importance of maintaining an appropriate funding stream for research in special education to ensure that robust research findings continue to be available to the educational community to improve outcomes for students with disabilities as well as typical learners.
