What mastery has done for our school

What mastery has done for our school

Jenny Laurie is a deputy head and maths teacher at The St Marylebone CE School in central London. The school was one of the very earliest to adopt a teaching for mastery approach in maths.

When two maths teachers visited Shanghai, they were particularly struck by the collaborative nature of curriculum planning there, and resolved to introduce a more collegiate way of planning at St Marylebone.

Initially something of a sceptic, Jenny explains why she has been completely won over by the changes they have made, and what she hopes this might mean for their GCSE results in 2020.

No time to listen to a podcast? In this short read, Jenny writes about Why mastery makes us optimistic about our next GCSE results.
