During a regular school curriculum, the material to be assimilated can be considerable, so much so that many concepts are only understood superficially, just enough to pass an exam. In my opinion, it is essential to establish a solid foundation before building new knowledge. The course is therefore structured as follows: - Review of relevant physical and mathematical concepts prior to the course. - Course overview: We identify the key concepts, what is well understood and less well understood by the student, in which case misunderstandings are addressed. - Practice: We put new concepts into practice through a series of exercises aimed at anchoring the learning. - Summary: I like to conclude each session with a discussion where the roles are reversed: the student explains the concepts covered in their own words. It is often by trying to teach in turn that we highlight our misunderstandings — and really consolidate our knowledge! "If you cannot explain something simply, it is because you have not understood it well." - Albert Einstein - Written record: I give lessons via videoconference, with a tablet and stylus as a visual aid. Notes are taken on Notability and are shared at the end of the session.
