Table mountain delta: Reflect. Connect. Be inspired!

This special issue comprises articles presented at the Fourteenth Southern Hemisphere Conference on the Teaching and Learning of Undergraduate Mathematics and Statistics, held in Cape Town, South Africa in November 2023. Each conference in this series is named a ‘Delta’ conference in recognition of the constant state of change experienced by educators and students alike. The conferences are also named in recognition of where they are held. As such, the 2023 conference is named Table Mountain Delta in acknowledgement of this characteristic Capetonian feature. This is the 10th such Special Issue, affirming the strong link between the Delta community and the International Journal of Mathematics Education in Science and Technology (IJMEST), a journal that provides a forum for researchers and practitioners to disseminate and derive insights from high-quality pedagogical research with tangible applications for the mathematics classroom.
