For your new Grade 10 classes starting CAT this term, here is summarised version — from my “Why choose CAT?” presentation — of what Computer Applications Technology is about. It is to ensure that your students are aware of the journey that lies before them and what they will be learning. It is a PowerPoint file with embedded fonts. Feel free to use it as an introduction lesson or edit it to suit your classes.
Here are some screenshots of the slides. There is also a fun video clip at the end.
