Step 1 — Big idea and YouTube title
- Core promise:
- AI should not replace teachers. It should multiply great teaching.
- Equity comes from three simple things at scale: timely feedback, right‑level practice, and caring follow‑up. AI can deliver all three to every child, even offline, at very low cost.
- When designed for low bandwidth and with open content, AI becomes a public good, not a luxury.
- One‑sentence big idea:
- Give every child the “good teacher effect” through low‑cost, offline AI that supports, not replaces, real teachers.
- Why it matters to a wide audience:
- Parents want fair chances for their kids.
- Teachers need time and tools, not more tasks.
- NGOs and policymakers care about the digital divide and measurable gains.

Step 2 — Five different opening hooks
-
Shared struggle
- Line: “We all remember the one great teacher who changed us. Now imagine never meeting that teacher—just because of your zip code. That is the quiet lottery we accept every day.”
- Beat: Pause. Look around. “What if we could end that lottery?”
-
Future vision
- Line: “Five years from now, a child in a mountain town can ask a patient tutor at midnight, in her own accent, and get instant, gentle feedback—without even being online.”
- Beat: “That future is not science fiction. It’s a design choice we can make today.”
-
Data chart
- Visual: Slide with two lines diverging (control vs. AI‑supported classes).
- Line: “This semester, in two county middle schools, math scores rose by 6.8 points vs. control. Low‑score students’ completion jumped from 54% to 79%. At a data cost of about 0.3 RMB per student per week.”
- Beat: “Same teachers. Same textbooks. One difference: adaptive practice and voice feedback, running on open tools and offline models.”
-
Personal story
- Line: “Jun used to hide his math notebook. He said, ‘I’m always wrong.’ Then the tool asked him to speak his thinking, and a calm voice said, ‘Good start—try step two.’ The first week he finished two sets. By week eight he was helping others.”
-
Provocative question (with a pun)
- Line: “What if homework could love you back? Not with grades, but with guidance. Not Artificial Intelligence—Accessible Instruction.”
Step 3 — Body structure with logical flow, examples, and evidence (target: 18–20 minutes)
Section 1: The problem we can all feel (3 minutes)
- The “zip code lottery”:
- A child’s teacher quality and time depend on where they live, not what they need.
- The feedback gap:
- Kids wait days for feedback. Low‑confidence students stop trying.
- The digital divide, reframed:
- It’s not only about devices or internet. It’s about the quality and timing of feedback.
- Global context (1–2 data points):
- World Bank reports high “learning poverty”: many 10‑year‑olds in low‑ and middle‑income countries cannot read a simple text. After COVID, this rose sharply.
- Human moment:
- Quote from a teacher: “I have 52 students. I can’t sit with each one when they get stuck.”
Section 2: Design principles for equitable AI (3 minutes)
- Teacher‑first, not teacher‑less:
- AI handles routine feedback; teachers handle meaning, motivation, and mentorship.
- Low‑cost, low‑bandwidth, offline‑ready:
- Models run on school devices, sync weekly. Data cost about 0.3 RMB per student per week.
- Open content, open audit:
- Open‑source item bank; transparent correction rules; local language support.
- Privacy by design:
- Minimal data, on‑device processing, clear consent.
- Measure what matters:
- Track low‑score students’ growth first, not just averages.
Section 3: The field case (5 minutes)
- Where and what:
- Two county middle schools. Math classes introduced adaptive practice plus voice‑based feedback for explaining steps.
- Used open‑source problem banks and small, offline models.
- How it worked:
- Short daily practice (15–20 minutes), automatic hints, spoken explanation captured and checked for key steps, instant feedback.
- Teachers got a heatmap: who is stuck, on what step, and sample student audio.
- Results (semester end):
- Math average: +6.8 points above control schools.
- Low‑score students’ completion: 54% to 79%.
- Cost: ~0.3 RMB mobile data per student per week.
- Third‑party review: 120 classroom observations by a provincial evaluation team documented higher time‑on‑task and more student talk.
- Parent roundtable: families said kids started to review mistakes at home without being pushed.
- Two mini‑stories:
- Student: “I like when it says, ‘Nice try. Think about step 3.’ It feels like someone is waiting for me.”
- Teacher: “I stopped carrying 200 notebooks home. I spend my time on the five students who need me most.”
Section 4: What this is—and what it is not (address concerns) (3 minutes)
- Contrast:
- Not robot teachers; a “bicycle for the teacher’s mind.”
- Not more screens; more feedback.
- Not data hoarding; data minimization.
- Bias and accuracy:
- Small, domain‑specific models; teacher oversight; error flags.
- Workload:
- Setup is one afternoon; teachers get weekly 10‑minute briefings, not dashboards with 50 charts.
- Sustainability:
- Open tools reduce vendor lock‑in; local teams can maintain content.
Section 5: A simple playbook to start in 90 days (3–4 minutes)
- 30‑30‑30 plan:
- Days 1–30: Baseline. Pick one grade and one subject. Collect starting scores and a short student survey.
- Days 31–60: Pilot. 15 minutes/day adaptive practice + voice feedback, 4 days a week. One teacher champion per grade. Parent info night.
- Days 61–90: Review. Compare gains vs. control classes. Focus on low‑score students’ completion and confidence.
- Budget example:
- 1,000 students x 0.3 RMB/week x 16 weeks ≈ 4,800 RMB total data cost.
- Roles:
- Teacher champion, IT lead, parent liaison, evaluator (can be a local university).
- Guardrails:
- Opt‑in, offline by default, content review committee, publish a short transparency note.
Section 6: Policy and partnership moves (2 minutes)
- Procurement standards:
- Offline‑first, open content, clear privacy, teacher control.
- Equity metrics:
- Require reporting on low‑score subgroup gains, not just averages.
- Public goods:
- Fund open item banks and small multilingual models (including dialects).
- NGO role:
- Train parent coaches; run student “explain your steps” clubs.
Section 7: The horizon (1–2 minutes)
- Near‑term upgrades:
- Dialect support; hint libraries recorded by top local teachers; student‑generated examples.
- North star:
- “A great teacher in every pocket” by 2030—no matter the zip code.
Step 4 — Rhetoric and storytelling devices to weave in (with sample lines)
- Contrast (problem vs. possibility):
- “Today, your zip code predicts your teacher. Tomorrow, your effort predicts your progress.”
- Parallelism (the rule of three):
- “Right‑level practice, instant feedback, human care—at scale.”
- Personification:
- “The homework now talks back. It whispers, ‘Try step two. I’m still here.’”
- Metaphor:
- “AI is not an autopilot for classrooms; it is power steering for teachers.”
- “It’s a light switch in a room that used to be dark between classes.”
- Analogy:
- “Think of it like noise‑canceling for confusion. It reduces the noise so the lesson can be heard.”
- Pun / double meaning:
- “A.I. here means Accessible Instruction.”
- “Let’s end the class divide inside our classes.”
- Memorable one‑liners (for slides and recall):
- “Feedback is a right, not a reward.”
- “Great teaching, at the cost of a text message.”
- “Small models. Big gains. Fair chances.”
- Visual cues:
- Slide 1: Diverging lines (+6.8 points; 54% → 79%; 0.3 RMB/week).
- Slide 2: Heatmap of where students get stuck.
- Slide 3: 30‑30‑30 plan timeline.
- Slide 4: Parent quote and teacher quote side by side.
- Emotional moments:
- Student audio snippet (10 seconds) showing “think‑aloud” before and after.
- A teacher’s short confession: “I almost quit. This kept me in the classroom.”
- “Talk Like TED” principles embedded:
- Emotional story (Jun’s shift from fear to agency).
- Novelty (offline AI, open tools, ultra‑low cost).
- Memorable structure (rule of three, short phrases, visual anchors).
- Clear, simple language throughout.
Step 5 — Closing with a future lens and call to action
- Summative contrast:
- “We could wait for more perfect bandwidth, more perfect budgets, more perfect plans. Or we can start with what we have: a way to give every child timely feedback, every day.”
- Call to action by role:
- Teachers: “Pick one class. Try 15 minutes a day for four weeks. Watch who speaks up.”
- School leaders: “Name one teacher champion and one IT lead this month.”
- NGOs: “Adopt one school. Fund the data plan and independent evaluation.”
- Policymakers: “Make offline‑first and open content the default in procurement.”
- Parents: “Ask your school for the ‘explain your steps’ practice—offer to host a roundtable.”
- Vision statement:
- “By 2030, a great teacher lives in every pocket, speaks every accent, and never gets tired of saying, ‘Try step two.’”
- Final line (memorable, future‑facing):
- “Let’s end the zip code lottery—not with promises, but with feedback. One hint at a time.”
