CAS Conference 2025: Tools for teaching and learning A-level content

I'll be demonstrating some free online tools/resources I've made to help me teach OCR A-level computer science. I'll discuss how to use them to teach the course content, and the kind of activities you can set for students with them too. Tools include: - Binary LMC simulator: a user-friendly animated simulator using 2's complement instead of denary; a great way to learn assembly code, the FDE cycle and much more - Pathfinding on real maps: visualise Dijkstra and A* algorithms on real maps with over 100k nodes - Sorting algorithms: bubble, insertion, merge and quick sort visualised, with lots of options - PageRank: create nodes and edges and iteratively run the PageRank algorithm on your graph
