Designing High Quality Research in Special Education: Group Experimental Designs.
Gersten, Russell; Lloyd, John Wills; Baker, Scott
This paper, a result of a series of meetings of researchers, discusses critical issues related to the conduct of high-quality intervention research in special education using experimental and quasi-experimental designs that compare outcomes for different groups of students. It stresses the need to balance design components that satisfy laboratory standards and those that reflect the complexities of real-life classroom teaching. Several controversial issues in group design are addressed, including the importance of clearly defining the nature of the independent variable, the value of conducting replication studies, measuring implementation, the use of quasi-experimental designs, and selecting measures to evaluate intervention efforts. The first section focuses on defining and making the instructional approach operational. The second section considers designs for in-depth understanding of teaching and learning, thereby probing the nature of the independent variable. The third section is on the selection of dependent measures. Also stressed are the importance of researchers reporting effect sizes as well as probability values from statistical tests and the need for researchers to use a set of common measures when researching a given topic.
