What to do about educational research's credibility gaps?

Abstract

Educational research is continually being thrashed for its poor quality. Several recent efforts to define better research standards have sputtered. Acknowledging others' arguments that the nature of educational research is applied (directed at problems of schooling), heterogeneous (multidisciplinary), and complex (multidimensional). we nonetheless advocate more widespread implementation of scientifically based research methodologies. Our central thesis focuses on the concept of credible evidence. We suggest that most educational research approaches that are in vogue today are incapable of yielding empirical evidence that is convincing from either a scientific or a prescriptive standpoint. After offering a refresher on the logic underlying carefully controlled scientific investigations and then contrasting current educational research inquiry with inquiry characteristic of medical research, we present an educational research model in which what we refer to as “randomized classroom trials” studies are accorded a position of prominence. We provide examples of candidate topics for such studies and discuss the challenging issues that must be resolved so that educational practice will be better informed by educational research evidence that is credible.
