At Thirsk School and Sixth form College we have looked to gather extensive evidence about how to close out gender gap. This has involved spending focused time in lessons, conducting targeted work analysis and consulting students, staff and parents. We have also considered the most recent pedagogic research. Based upon this evidence we have come up with a range of strategies, both for our staff in the classroom and on a whole school basis. This session will give an overview of our findings, and then introduce the strategies that we are now employing as a school.
