Mixed Research Design

Nature of the Research Approach, Basic Design and Variables

The proposed study utilizes both quantitative and qualitative traditions and can therefore be termed a "mixed research design" (see: Creswell, 1998). The primary purpose of the research is to determine whether there are significant differences in the effects of three teaching strategies in reducing the aggressive behavior of non-verbal, autistic children. Participants in the study will be counterbalanced by gender across the three teaching strategies which is to say there will be equal numbers of boys and girls exposed to each of the three strategies. This will result in the following 3 x 2 factorial design:

Strategy A Strategy B Strategy C

As can be seen from the graphic depiction presented above, for the qualitative element of the study, there are two independent variables which are: (1) the Teaching Strategy variable with three levels: A, B, and C; and (2) the Gender variable with two levels: males and females. The dependent measure will be subjects' change scores (Posttest minus Pretest) on the Aggressive Behavior Checklist (Shapiro, 2000), a measure of level of aggressive behavior in children 11 to 12 years of age.

The qualitative element in the design will consist of open-ended interviews conducted with teachers in which they will be asked questions regarding their perceptions of each tested Teaching Strategy and how effective they believe that each strategy has been in terms of reducing sample subjects' aggressive behavior.

Participants in the study will consist of 36 students (12 boys and 12 girls, ages 11 through 12) drawn from a large local special education school serving autistic children and their teachers.
