I have just finished a unit for a year 7 STEM class. This is based on the resources available at do your bit, a challenge for children and teens to combine creativity and technology in solutions for the Global Goals. The coding is Microsoft MakeCode. It is mapped against both Digital and Design Technologies ACARA standards.
I have previously used the excellent Introduction the Computer Science course and have recently discovered that there is a MicroPython version, maintained by Carl Lyman. I wanted to cover the ACARA Digital Technologies Knowledge and Understanding: Investigate the role of hardware and software in managing, controlling and securing the movement of and access to data in networked digital systems (ACTDIK034). For this, I found another excellent resource: Networking with Microbit.
I have mashed all these resources together, to pitch at a year 9 class in 2020. I will only see this class for 140 minutes a week, so I have compressed quite a lot. If I have an extra 70 mins, then I would have included all innovation mini-projects and completed the Networking book. If you have the time, I would add these in. The assessment is an exam, because I do projects all the rest of the year and I need them to be prepared for exams in 11-12. Hopefully, you can figure out where I have mapped the exit ticket questions in by the WALTS.
