With more than twenty years experience teaching in schools, I am able to assess ability and stage very quickly. Once a level for a student has been established, the lesson is broken into stages: A starter that consolidates previous learning, a main part which goes through the main topic and a final section about problem solving. For GCSE and A level, a significant focus of the lessons is exam technique and the use of correct terminology in answering the questions. Where appropriate, youtube videos of no more than five minutes duration are deployed to enhance understanding of concepts which might be deemed problematic. Quite often a different person explaining and demonstrating the same concept can unlock understanding. The materials used in the lessons have been developed over a twenty year teaching career and have been tried and tested in a variety of different environments. Where a concept is being explained, such as binary, hexadecimal, packet switching, recursion, trees, CPU etc, a whiteboard and pen (now a tablet) is used. If the lesson is about something more knowledge-based, such as input or output devices, then there is more reliance on a pre-existing presentation such as a powerpoint. Once the main topic of the lesson has been completed, we (me and the student) will complete a series of questions together. These could be from past papers or from my own devising. In most cases, the student will receive a summary of the lesson along with a more in-depth development of what has been learned.
