Conference Takeaways: Comparative Judgement – with a cameo from Daisy Christodoulou!

Welocme to another epsiode of the Mr Barton Maths Podcast

Now, this episode is a little different to the usual ones.

For a start, it is one of my Conference Takeaways, where I sit down at the end of a conference or some training to help collect my thoughts on what I have learned both for my own benefit and in the hope that teachers who cannot make the conference might find it useful. But whereas in the past I have recorded Conference Takeaways from MathsConf, BCME & researchEd, where there are lots of different workshops to reflect on, this time the training was very specific and… wait for it… it was non-maths specific!

Yes, I was lucky enough to attend a session entitled Refining assessment and reducing workload with the wonderful Daisy Christodoulou, author of Seven Myths about Education, Making Good Progress, but who is undoubtedly best known as a former guest on this podcast. Indeed, at the end of that interview – which I wholeheartedly recommend you check out if you have not heard it – Daisy discussed the concept of Comparative Judgement and her work with No More Marking. The concept fascinated me at the time, and since the interview Daisy has done a load more work, and hence when I heard she was embarking upon a bit of a North West tour – calling in at such glamorous locations as my very Bolton, Southport and Warrington – I was desperate to get along to a session.

This podcast is in 3 parts.

First, my former colleage Jon Sellick and I describe the basics of comparative judgement, and what we did in the session. Now, just a word of warning for all my maths listeners, Jon is what can only be described as an English teach – I figured I needed to have at least one token non-maths friend – but his presence was extremely useful as much of the session was focused on a writing task where I was completely out of my depth. But that is one of the myths of comparative judgement that I hope to bust – whilst it is undoubtedly a tool that lends itself extremely well to long-form writing tasks, I believe it has an interesting and exciting role to play ion the world of mathematics, which I discuss at the end of this episode.

Then, in the middle, we hear from Daisy herself, as I was lucky enough to grab her to ask three questions that had been playing on my mind throughout the session.

Finally, Jon and I return to share our key takeaways from the session – how will what we have seen today actually affect our practice in the classroom?

A few disclaimers before we crack on.

Firstly, Jon and I are anything but experts in Comparative Judgement and we are more than a bit ropey when it comes to trying to explain how ranks get turned into grades and levels. Fortunately, Daisy and her colleagues at No More Marking do a far better job than us, and I have linked to a great blog post in links below.

Secondly, the bulk of this episode was recorded outside a coffee shop in Birkdale, just outside of Southport. This sounded a good idea at the time – the sun was shining, the shirt sleeves were rolled up, Jon and I had visions of ourselves being very much like James Richardson from Football Italia in the 90s sipping a latte on a Piazza in Florence – but the trade-off is that you do get a fair bit of background noise. On a positive side, if our conversations bore you, the table next to us are having a great time.

Finally, when you hear from Daisy, the background noise reaches a new level. But as I have started saying, treat this as one of Bjork’s desirable difficulties and listen extra hard to learn even more.

Anyway, I really hope you enjoy this one and find it useful. As I say, I am increasingly swayed by the power of comparative judgement, even for us maths teachers. But this is definitely an episode to share with your non-maths colleagues who want to no more. As Jon and I discuss in the episode, you can set up a internal use of comparative judgement for free on the No More Marking website, and I would highly recommend you do.
