In this chapter, we described issues in conducting intervention research with students with learning disabilities on the secondary level. We main- tained that interventions should be well-grounded in theories of learning as well as characterizations of learning disabilities (Pressley, Scruggs, & Mastropieri, 1989); that they should first be conducted in a series of highly controlled, laboratory-like experiments to carefully assess the potential utility of the intervention; and that, if the intervention is suc- cessful in highly controlled settings, it should then be evaluated in class- room applications. We maintained that research designs should evolve as the research questions become more applied, and that the results of laboratory research should be used to support the findings of classroom applications. Finally, we described several research designs that we have found useful in conducting classroom intervention research. There is a great deal more to conducting intervention research, of course, than experimental or quasi-experimental design. Intervention strategies likely to be effective must be identified, relevant literature must be reviewed, experimental materials must be developed, and cooperative schools, teachers, parents, and students must be located. Nevertheless, inadequate research designs can invalidate the best and most successful efforts in all of these areas, while effective and practical research designs can do much to document the best practices and advance our knowledge of effective interventions with students with learning disabilities.
