The Use of Moderator Effects for Drawing Generalized Causal Inferences
Jaciw, Andrew
Society for Research on Educational Effectiveness
This work has a three-fold purpose. The first is to set out the rationale for an alternative approach for assessing the generalizability of research findings. (It is related to but not equivalent to the CE method.) The second is to formalize this approach through a quantitative model. The third is to apply the approach to the results of the Tennessee STAR multisite trial of the effects of class size reduction to investigate: (1) the generalizability of the average effect estimate across sites, and (2) the power of "convenience variables" (basic demographic variable) to strengthen the external validity of the findings. (Contains 1 figure and 1 table.)
