Dr Rehan Shah and his third-year undergraduate student researcher, Mr Ilanthiraiyan Sivagnanamoorthy (Ilan) delivered a mathematics education research workshop on their education research work on 'Identifying and critiquing potential threshold concepts in mathematics teaching' to mathematics educators and teachers at the national UK-wide Joint Conference of Mathematics Subject Associations dedicated to the theme 'Future Proofing the Curriculum' held at the Holywell Park Conference Centre at Loughborough.

The workshop commenced with an introduction, background and examples and non-examples of threshold concepts in mathematics, which was delivered by Ilan. This was then followed by an interactive, hands-on activity led by Dr Shah with participants actively engaging in identifying and critiquing potential threshold concepts from a given list of concepts applicable to KS5 secondary-school and introductory undergraduate level mathematics. During the session, participants were introduced to the threshold concepts framework which they applied to classify which of the given mathematics concepts they deemed to be threshold concepts. This was then critiqued and reviewed through discussion-based feedback delivered by each of the participant groups.

The workshop was extremely well received by all of the participants, all of whom actively engaged in reflective discussions and insights motivated by their own teaching experiences and the learning journey navigated by their students. Dr Shah and Ilan's workshop promoted extremely enriched participation and a fascinating exchange of ideas between secondary school teachers, educators and university academics. The outputs from the workshop yielded valuable data insights for their ongoing research work on assessing threshold concepts through development of proficiency-based mathematical assessment inventories.
