You have probably noticed that it has gone a little quiet of late on my Computing Blog. This is mainly due to the fact that my students are currently completing their first controlled assessment task and therefore there is not much to report. However, in the meantime, here is a collection of resources I have collated to help you teach the Computing theory element at GCSE level.
