It seemed appropriate tofeature this article from MedicalEducation in The Clinical Teachergiven that it touches on some ofthe factors that differentiate thetwo journals. It also addressesan issue that resonates inter-nationally: the ‘Cinderella’status of medical educationresearch.

Clinical teachers tend to beclinicians first and foremost, andas such are accustomed to theirpractice being underpinned by thebest available medical evidence.When the time comes to do abit of teaching, however, someclinicians are dismayed to findthat the educational approachesthey are expected to follow arenot based on published screedsof double-blinded interventiontrials. But does this maketheir teaching methods any lessvalid?

Dr Glenn Regehr from theUniversity of Toronto in Canadaacknowledges that those engagedin health professional education(such as clinical teachers) tendto view the physical sciencesas the ideal model for research,and many dismiss educational

research as failing to reach ascientific standard of proof.Consider medical school as apharmaceutical intervention:surely any drug that costsbillions of dollars worldwide todeliver, and has such a signifi-cant impact on young people’slives, would need to demonstrateindisputable beneficial outcomesover the long-term? How manymedical courses would survive apharmaceutical standard cost–benefit analysis?

Regehr identifies this sort ofthinking as indicative of theclinician’s desire for the ‘impera-tive of proof’ coupled with the‘imperative of simplicity’. We’renot that comfortable with con-cepts we can’t disassemble intotheir component facts to seeexactly how they work. I recallbeing sent to a managementcourse years ago where the oldchestnut about frogs and bicycleswas trotted out: education ismore like a frog than a bicycle. Youcan pull a bike apart and put it backtogether again so that it worksfine. Try that with a frog.

The article explains howrequiring proof of efficacy as thegoal of educational research lim-its our understanding of what’sactually going on. This is com-pared with subjecting our teach-ing to summative assessment: it

either passes or fails, never mindthe depth of understanding. Reg-ehr deplores our repeated at-tempts to reduce the complexitiesof medical education – dependentas they are on wildly chaoticvariables in teachers, learners,patients and contexts – to a seriesof simple and reproducible facts.He draws parallels with earlyphysicists (including such wor-thies as Newton and Einstein)attempting to explain the uni-verse in a few elegantly simplerules, or even a single equation.Then quantum physics came alongand everything became chaoti-cally messy again.

Regehr really hits the mark inthe last few pages, when he givesus permission to stop worryingabout the answer and concentratemore on understanding; this is anapproach we’ve been trying toinstil in our students throughproblem-based learning for years,so it seems fair to take some of ourown medicine. He wants us to shiftfrom the imperative of proof to animperative of understanding, andto read the medical educationresearch literature not to find sci-entifically proven models to copybut to better understand howsomething might work in our owncontext. He’s right: research inhealth professional education isn’trocket science. It’s much morecomplex and organic than that.
