@helenjwc @danieltybrown @CornwallMaths @andreapitt24 @NCETM @ThinkingMaths @RuthTrundley I've been thinking about the reductionist approaches, and how they claim to be research-based. I think this is true, but it's an artefact of research methodology. In a psychological experiment you simplify: you test first, change one thing, and test after, to look for an effect.+ @helenjwc @danieltybrown @CornwallMaths @andreapitt24 @NCETM @ThinkingMaths @RuthTrundley This scientific approach is very powerful in all sorts of ways. But it's going to point to and validate approaches that mirror its own methodology, the 'change one thing at a time and keep everything else the same' way of doing things.
