Scratch + Python + AI

ICT teacher pain · Essai solution

EDB publishes CT concepts but no coding materials — schools build from scratch.

All 4 EDB Primary CT units come with matching Scratch-style block activities (Cat Move, Draw Square, Counter, Bouncing Cat, etc.).

You want to teach Python in junior secondary, but installing + account management + firewalls is a nightmare.

Python runs in the browser via Pyodide v0.29.3 — iPad-compatible Turtle, matplotlib, and games. Zero installs. Zero accounts beyond Essai login.

EDB has no primary AI curriculum yet, but waiting isn’t an option — and external AI isn’t safe for kids.

"AI for Primary" is our own 5-lesson track using simulated AI (no external LLM calls). Safe by default, zero cost, parent-friendly.

Key features

Scratch-style block playground

Built on Blockly · 12 sprite emoji (cat, fox, panda, robot, etc.) · motion / looks / events / control blocks · confetti on success.

In-browser Python · Pyodide

Pyodide v0.29.3 · no installs, no accounts · supports Turtle graphics, matplotlib charts, and Python games (Guess My Number / RPS / Mad Libs).

AI for Primary (Essai-original)

EDB hasn’t published a primary AI curriculum yet. Our 5-lesson track: Is This Fair? / How AI Learns / AI in My Life / Tell the AI About Your Day. Simulated AI, safe by default.

AI for Secondary · Prompt Lab

5 LLM-era lessons: How ChatGPT Really Works / Prompt Engineering (MTR scenario) / Deepfakes / Bias / Classify Movie Reviews.

Bilingual · iPad-ready

Every lesson in English, Simplified Chinese, and Traditional Chinese (HK). Touch-friendly (≥44pt targets), most lessons doable without a keyboard.

AI-generated kawaii thumbnails

Every hands-on lesson has a Gemini-generated kawaii illustration (29 SVGs). Primary kids recognise + remember content visually.

How it works

Pick grade + unit

Student picks Primary or Secondary, then unit (4 Primary CT + 9 Junior CL + 6 DSE core + 3 DSE electives).

Work through it · auto-graded

Concept lessons MC-checked; coding exercises judged by whitespace-normalized + regex + keyword matching; AI lessons use keyword analysis.

Free practice

CT-U2 free sandbox · CL-U6 Python games · AI prompt lab for open-ended play. No teacher presence needed.

FAQ

Does the AI prompt lab call real ChatGPT?

No. For safety and cost control, the prompt lab uses simulated AI — a keyword-based response bank with explicit target validation. No external LLM calls, zero cost, zero privacy risk for primary-aged kids.

Does Python need to be installed?

No. Pyodide v0.29.3 runs Python in the browser. iPad or laptop — Turtle, matplotlib, and games all work.

Is the Scratch section real Scratch?

No — we built it on Blockly with Scratch-3-style semantics (move / say / repeat / if-then / event blocks). 12 sprite emoji options, confetti on success.

How do you align with the EDB curriculum?

Primary CT (4 units) matches EDB Computational Thinking – Coding Education (2020). Junior CL (9 units) matches the Technology Education KLA. DSE core A–E + electives A–C match HKDSE ICT. AI tracks are Essai-original (EDB hasn’t published a primary AI curriculum).

Is student data used to train AI?

Never. Each school has its own tenant; Essai Sovereign (on-prem) available for stricter isolation.

Can we fund this with the EDB HK$500k programme?

Yes. Essai meets EDB Circular 221/2025. We provide the application template.
