@profaliceroberts.bsky.social thanks for a fabulous evening in Leicester. As a teacher I have full admiration for you speaking so eloquently for 2 hours with no notes (& very few bullet points!). Fascinating subject matter.

Such a good lesson with y13 today going through exam Qs but using them as jumping off points to revise different topics, check key definitions as well as model exam technique. Any time they couldn’t answer a Q the topic went on their 'I don’t know' list to inform their revision. #ITeachBio
