"I like it" is not good enough
Creative conflict is the ability to agree to disagree, and use the disruption of a disagreement to make your work better. It relies on the partners in disagreement to both be on top of their game, both of them respectful of the other's views on how something might be made better.
Teachers seek this creative, quality feedback discourse every day in their students' work. But every month I bump into another educator who will not "believe" that the practice I'm sharing with them will make their students' outcomes better. The frustration of practice being negated by a simple "I don't believe this will work with my students / in math / in this school" is hard for me to mask - if you want to know one of my 'buttons', press this one.
The video clip I show in return, helps those who don't understand creative conflict get the point, without having to take it personally. It also shows the subtle difference between simply taking research "as is", and having a critical eye on the research.
Barenboim's masterclass pianist plays at a dynamic which is not written in the piece (like a teacher choosing to ignore what a piece of research says). When pushed on why he does it, he says: "because I like it". Barenboim has two options in his potential reply. One would be:
"But the manuscript says this, so play it like that".
This is the musical equivalent of what might be said by the emergent research-led cabal who wouldn't have a teacher teach a certain way unless it had been researched robustly that way first.
Instead, Barenboim asks him to reflect, to think about why he's taking the manuscript / the research and interpreting it differently, in his own style. It's an example of the fine line between virtuoso and just getting it wrong, in spite of what the manuscript suggests you might do for 'success'. And the clip makes the subtle, nuanced point in a way far more subtle and nuanced than most edu-speak can ever manage.
