A Computing teacher working in Glasgow.

I don't know about others, but I've found the studious kids have exhausted their stock of PPQs.

Made a couple of unseen N5+H revision papers for my classes out of rejected prelim questions.

H = Section 1 only (2 papers)
N5 = full paper (no db)

#LCT5 was a great conference and has inspired me to write a blog about autonomy tours as a way to quickly and easily think about and improve lessons that draw on other subjects to teach Computer Science. It uses the example of teaching using Conjuring. See

@mrneil_CS @MSFT365Designer Oh… l like the minifig one. Are you going to share the prompts, or are you going to make me work it out myself as a learning opportunity.

An early Christmas present 🎁 for anyone teaching python 3 in the BGE, National 4 or National 5 level CS. Four pages of quick reference cards with short but meaningful python examples grouped into common patterns and algorithms. See CSS Microsoft team on Glow or DM me for a copy

Thanks to @ScullionToni for drawing this to my attention.

📢Visibility of female role models in STEM subjects is so important to help encourage girls into these areas.

STACS features the amazing high quality @codeorg videos with brilliant female role models throughout all of our 200+ hours of teaching materials!

@CompSciAdams By way of experiment, I tried this:

[David Muir - Computing Teacher @DdmTeacher]

@CompSciAdams Assuming that is the problem, my guess would be yes. I remember using the Acorn spreadsheet on the BBC Micro (yes, I'm that old); it was notorious for that kind of error. To calculate with money, you had to do it on pence and then convert to pounds and pence at the end.

[David Muir - Computing Teacher @DdmTeacher]

@CompSciAdams …(cont.) Same is true for binary fractions. Some can be expressed exactly, others can’t… and there isn’t a direct match. That is, just because you can show it exactly as a decimal fraction does not mean you can show it exactly as a binary fraction. 2/2

[David Muir - Computing Teacher @DdmTeacher]

@CompSciAdams Possibly to do with binary representation of fractions rather than just “rounding errors”. There are certain fractions we can represent exactly as decimals (e.g. a half as 0.5) where as others we cannot express exactly (e.g. a third as 0.33 recurring)… 1/2

@ScullionToni Thank you. (Currently blushing scarlet!)

[David Muir - Computing Teacher @DdmTeacher]

@CompSciScot Thank you! Not sure I deserve that… but thank you anyway.

[David Muir - Computing Teacher @DdmTeacher]

@jgmwalsh Thank you, John!
(I still remember coming to see you when we were working on the Higher materials and being jealous of you collection of Doctor Who videos!)

Found this on my desk when I came back from lunch! 😁

First time trying the school’s 3D printer. Decided to go for something small and simple just to try it out. (Minifig Black Widow included for scale.) So, what should I print next?

A bunch of apps promise to detect ChatGPT. That's great! But before you go uploading student assignments to them, here are a few questions to ask yourself...

[Computing Science Scotland @CompSciScot]

#ChatGPT is a huge topic for discussion right now in education.

What are peoples thoughts about it for our subject?
