Babcock Mathematics Research Talks

Research can inform practice but it is often only well-funded research that comes to the attention of teachers and maths educators. The BMR talks are intended to provide access to small-scale research projects of value and interest to teachers and all involved in mathematics education. The talks run as one hour online sessions which are recorded and made available.

If you are interested in presenting a talk as part of the series please contact
