I'm the Head of Computer Science and Digital Technology at a large secondary school in Wales. With a background in primary teaching, I've spent my career finding genuinely impactful ways of integrating technology into the classroom, from EYFS to KS5. I love automating the boring stuff to make room for the fun bits. ✨ Big fan of micro:bits for bringing code to life in the classroom. Also, I've worked with some well-known educational publishers to develop curriculum content and train fellow educators.

• 📝 Google Slides Assessor
  A tool that uses Large Language Models to grade student work submitted via Google Slides, checking for completeness, accuracy, and key concepts. Actively in development, with plans to integrate features from Assessment Bot.

• 🤖 Assessment Bot
  My first experiment with LLM-based assessment. It marks Google Forms submissions, provides feedback, and generates a DiRT sheet & heatmap. While no longer actively developed (it currently stands as a monument to technical debt 💀), key features will be incorporated into Google Slides Assessor.

• 🛡️ Year 10 Pentesting Practicals
  Resources to get GCSE students (14-16 years old) into penetration testing, aligning with Unit 1.4 of the OCR J277 GCSE spec. Designed to give students a taste of using real (if old) pen-testing tools while ensuring network security, each task runs from a bootable USB stick. This helps ensure that you retain complete control over potentially damaging tools at all times.
