Introduction to Comparative Judgement

As Director of Education at No More Marking, a former school teacher and the author of Teachers vs. Tech, Making Good Progress and Seven Myths about Education, Daisy Christodoulou has long-held interest in assessment and feedback.

In this session, she will introduce participants to the principle of comparative judgement - an alternative to conventional forms of marking.

According to No More Marking's website:

Marking does not work when it involves any degree of human judgement. This is due to a simple principle.

"There is no absolute judgement. All judgements are comparisons of one thing with another". (Human Judgement: The Eye of the Beholder by Donald Laming, p.9.)

Laming has shown that at best our judgements are ordinal. We can place things in an order, but scarcely more than this. Ask two people to apply a mark scheme and you will most likely get different marks. Ask people to place two scripts in order, and you will get more consistency.

This promises to be an engaging and thought provoking session. Any members of staff who teach are welcome to attend.

Date: Tuesday 9th February

Time: 2pm-3pm
