Jane Florsham was a senior teacher, and now works as an educational consultant. Interview by Amanda Roper. Your son needs to distil the information he has learned into more manageable chunks. He needs to go through his notes and reduce them into topic areas, and then key notes. These form the 'pegs' on which you can hang your wider knowledge.
Visual learners use flowcharts, spidergrams, charts or mnemonics.
These take a large quantity of information and then present it in a simplified, but memorable, form. Put them up on the walls in your bedroom to memorise them. As well as listening to it, the process of selecting the narrative for your revision tape will help to fix ideas into your sub-conscious. Kinesthetic learners learn best by doing. The very act of writing down revision notes is a form of active learning, as is watching videos.
