To document the effectiveness of practices in special education, different research questions are needed that call for different types of methodologies. Educators examine four types of research methodologies important to special education: experimental group, correlation, single-subject, and qualitative designs. Particular attention is given to single-subject research designs that are used to study behavioral change in an individual or a group as a result of an intervention. Topics include reliable measurement, repeated measurement, description of conditions, baseline and treatment conditions, and single-variable rules.
