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.
I have recently written a unit for year 7, to transition them from block coding to text-based coding in Python. In years 8-9, I continue this somewhat by using block coding as my algorithm designer. Here, students can design their solution, test it and then refine it to make it more efficient. For example, instead of a series of sequenced commands that repeat, students can get the sequence working and then refine the algorithm with loops; and then test it again. I find the drag and drop nature of block coding to be a better environment for prototyping because you can work on several iterations of a design quite quickly and its a more visual experience as well. In particular, its probably a superior environment for beginning with embedded systems, such as the BBC Micro:bit or The Circuit Playground Express. In fact, these environments have a text coding view as well; facilitating the transition to text-based coding.
In this unit, I introduce students to python via turtle graphics. Here is my Unit; enjoy!
