'Medical myths' exposed as untrue

BBC NEWS | Health | 'Medical myths' exposed as untrue: "Dr David Tovey, editor of Clinical Evidence journal, said: 'The difficulty is it is often hard to disprove a theory.

'On the flip-side, absence of evidence does not necessarily mean absence of effect.

'Where reliable evidence becomes really important is in helping people make serious decisions about harms and risks."

Although this article isn't on first look that relevant to E891, it does contain a useful little quote which is worth bearing in mind when thinking about evidence-based education. "absence of evidence does not necessarily mean absence of effect" - and it got me thinking, if you base your practice on evidence-alone then aren't you missing things which are significant in terms of the effect they're having but that don't provide evidence? Dangerous to imagine that evidence-based practice is the only way forward when there's so much we don't know about human behaviour and social / learning interactions. There's an inherent arrogance in evidence-based practice which seems to say we know the problem, we now know the solution... ta daaaa! But who's to say what's really the problem and what are the desirable outcomes we should be working towards? And what happens when the evidence is revised in years to come and it turns out that the right way was the wrong way?!

Absence of evidence does not necessarily mean absence of effect - definitely worth bearing in mind when considering evidence-based practice in education.
