External Validity in the Context of RCTs: Lessons from the Causal Explanatory Tradition
Jaciw, Andrew; Newman, Denis
Society for Research on Educational Effectiveness
The purpose of the current work is to apply several main principles of the causal explanatory approach for establishing external validity to the experimental arena. By spanning the paradigm of the experimental approach and the school of program evaluation founded by Lee Cronbach and colleagues, the authors address the question of how research programs that involve experiments can be expanded to make external validity more of a priority. They bring to bear three central concerns of the causal explanatory approach on the activity of conducting randomized trials with a view to establishing external validity: (1) the role of interactions, (2) the need for ecologically relevant generalizations (3) the time-dependency of generalized causal inferences. (Contains 1 figure.)
