Criteria for evaluating interventions.
By common consent there is a 'gold standard' in reference to which the efficacy of medical interventions needs to be evaluated. It is suggested in this paper that in educational research achievement of this gold standard is rarely possible. It does not follow, however, that research that falls short of this standard is therefore valueless; there may be many different kinds of good (and less good) reasons for accepting particular conclusions.
