The Covid-19 pandemic has focussed attention on online education. This stimulating virtual session of BRIDGE’s Maths and Science Community of Practice engaged with two presenters who are working in this space. Nonhlanhla Masina of the African School for Excellence shared lessons learnt while implementing remote teaching and learning of maths and science, including using the home as a learning environment. Ilyaas Amien of Tutonic, an online maths tuition and support service developed by university students, described their journey towards providing effective concept-based maths support to high school learners.
