Ta da! Happy Saturday @GrumpyCompSci and @lfc7646 Pretty proud of this merge sort revision and practice guide. The description is a bit clumsy but thought the graphic was well worth the effort... drive.google.com/file/d/1_gdjq-…
I’ve worked in industry and had a lot of appraisals: a meeting with your manager about what you’ve done well over the past year and what they can support you with over the next. So why is a teacher’s appraisal just a list of extra unpaid tasks?
I used to work in an independent school. Teachers had 20% PPA and after-school meetings were rare. It was a game-changer for work-life balance! standard.co.uk/news/politics/…
Good morning- not sure who needs this reminder today - You will definitely be doing way better than you think you are x ❤️
What about this for an integer (do you get the pun?) #STEM #edutwitter #teamcompsci
Creating some dual coding support sheets on data types. This works for a float, right? #STEM #edutwitter #teamcompsci

Another resource for OCR J836 IT, this one’s for your students. R050 units 1 and 2 are online now, the rest are on their way. #BackToSchool #edutwitter #teamcompsci computingrevision.net/j836-cambridge…
If you’re teaching OCR J836 IT in September, the first two units of R050 are now on TES. Here’s a link to Unit 1: Design Tools tes.com/teaching-resou…
Bringing back all the excitement of seeing the latest edition of Zzap!64 in the newsagent’s! @JazRignall #retrogames
Good luck to all the students receiving their GCSE results. Well done to all their teachers, TAs, mentors, and everyone else who supported them 🏅 #GCSEResultsDay
Creating a text-based adventure game on an eInk display? Yep, we can do that! #Python #RaspberryPi #STEM
It’s breaking-up day for many of us, and for me, the end of my first year as HoD. It’s been great, but I could sleep for the next six weeks. Except I have too much work to do! Well done everyone. Alarms off. We made it! 😎
Having a mooch around #FestivalofComputing25 and I really want a go in the C5
When you’re sat outside the pub, in the sun, shades on, a beer in each hand, and you hear “Hi Sir” 😱
Creating a student IT workbook, but couldn’t resist a bit of #RetroComputing geekiness 🤓 #edutwitter
School haven’t specified what “dress for comfort in heat” means, so it’s shorts, t-shirt, shades, and a straw hat for me! 😎☀️
