What it is

EduBridge generates structured English-as-a-foreign-language activity plans for teachers in low-connectivity classrooms. Teacher picks an age group and topic, EduBridge returns a four-phase activity plan in validated JSON, the teacher prints it once and runs it with zero technology in the room.

Built for the Kaggle Gemma 4 Good Hackathon (Education track), submitted by vøiddo.

Why Gemma 4

• Function calling enforces a JSON schema — no malformed or hallucinated activities
• Multilingual prompts — teacher can describe the topic in their native language
• Open-source weights — schools and NGOs can self-host without recurring cloud cost
• Runs on Kaggle free tier — zero infrastructure spend for end users

Who it is for

• NGOs serving children in sub-Saharan Africa, South and Southeast Asia, rural Latin America
• Independent teachers and tutors working without reliable internet
• Education research projects studying offline AI-assisted curriculum

Addressable population estimate: 50–100 million children in connectivity-constrained classrooms.

                                                       classroom (offline)

Every generated activity includes:

• teacher script — the exact words to say at each step
• student actions — what the children do, broken down by phase
• vocabulary list with translation hints
• assessment guidance — short observable checks per phase
• explicit offline notes — what to do if the projector breaks, the power cuts, etc.

Age groups supported

age	scope
5–6 (Kindergarten)	letters, colors, numbers, 2–3 word vocabulary
7–8 (Grades 1–2)	short sentences up to 10 words, seasons, descriptions

Demo modes

• Fixture — pre-generated real Gemma 4 outputs bundled with the demo, always available, perfect for showing the system without a network round-trip.
• Live — calls the Gemma 4 endpoint on Kaggle; requires the notebook to be running.
