Today's Gratitude Item: That most of my students are enjoying our Computing / IT classes. After teaching Maths / Science where kids don't really have a lot of choice in being there, it's great to finally get to teach a subject that they enjoy. It's still a massive amount of work, but at least it's fun too.
