Telemedicine & AIUnlock 4 · Unit 3 Medicine · one video, two halves, one question

Core question: How can we access reliable health information with less effort — in the age of telemedicine and AI?
Listen predict · compare Speak use local care fast · say it in full sentences Team build the answer together Real life handle a real visit

Four things you will be able to do by the end — and you will do all four on this screen.

1

A visit to the hospital

You are the patient · three stops · look, tap, and say
Who are you today?
Walk through three stops. At each stop: look, tap, and say one sentence.
After class — the full seven stops (explore on your own)

What is telemedicine?

A short animation · the three ways · concept check
Watch: What is telemedicine? · 38 secondsno subtitles

Which three ways did you see? Watch once, then tap the ways you caught.

message phone call video call an ambulance ride
The three ways: message · phone call · video call. (An ambulance ride is not telemedicine — you and the doctor are not far apart… and it is not advice from a distance.)
Different doctors and apps use one, two, or all three — but the idea is the same: a doctor's advice, without the same room.

Concept check 1

In telemedicine, is there still a doctor?

Yes — there is still a doctor (just far away).
No — telemedicine means no doctor at all.
Yes, there is still a doctor. Telemedicine is a doctor's advice delivered by technology — not a machine replacing the doctor.
3

Predict the aspects

Skill — strong viewers predict a list · seed: commuting

The topic is telemedicine. Which aspects of “telemedicine vs. an in-person visit” might the video mention? We seeded one — commuting.

Your turn: add one or two aspects of your own (up to four if you want a challenge).

commuting (seed)
You will tick, cross, or question-mark these after the first viewing — “never mentioned” is an honest answer too.
4

First half of the video

0:00–0:59 · no subtitles · check predictions · T/F · main idea
Watch (0:00–0:59)no subtitles · listen for pros and cons

Check your predictions

Go back to ③. For each aspect, mark it: the video mentioned it · it did not · ? you are not sure.

Add one reason for one of your marks — say it to your partner: “I marked ___ because I did not hear it.”
No aspects yet — add them in ③.

True or false?

Read each sentence, choose T or F, then check and read the evidence.

Main idea — choose one

After one viewing: what is the first half of the video mainly about?

5

Online info & AI diagnosis

A fictional scenario · one vote · two predictions
FICTIONAL SCENARIO

Lin has a headache. She searches online and finds two different explanations. Then she asks an AI chatbot — and gets a third one.

All three sound confident. Before trusting any of them, what could she check?

Think on your own — then vote below. (Later: bring your search results to the doctor as questions to check, not as answers.)

Vote A — health information online

Is medical information on websites generally reliable?

Tap your choice — you can change it.

Two predictions — write before the second half

P1 (comparison). By the end, which will the speaker trust more — what you find online, or a qualified doctor? Predict, and say the reason you expect.

P2 (the point). What will his conclusion be — and why does he believe it?

6

Second half of the video

0:59–2:29 · no subtitles · check your predictions · T/F · the point
Watch (0:59–2:29)no subtitles · listen for the speaker's point

True or false? (from this half)

The speaker's conclusion — in your own words

You wrote a prediction in ⑤. Now that you've watched: what does the speaker conclude, and what reason did you hear? Write it yourself first — then check the reference.

“The best medical advice ultimately comes directly from a qualified medical professional.”
He believes it because checking symptoms online can misdiagnose, make you dismiss an illness wrongly, and turn you into a cyberchondriac — so anxious about imagined symptoms that you become physically ill.
Say it back — replay the final line and read it aloud with the speaker.
7

Group discussion

Three kinds of resources · the core question · speak with evidence

Sort the resources — three different things

These are not the same kind of thing. Tap a card, then tap the column it belongs to.

Doctor-led telemedicine
a real doctor, advice from a distance
Online health information
webpages you read yourself
AI-generated information
transfer discussion — the video does not discuss AI
Sorted: 0 / 6

Four-square notes — benefits & limitations

For each source, write one benefit (good point) and one limitation (bad point). Then label each idea: “in the video” or “my inference” (my own reasonable guess).

Telemedicine — benefits
Telemedicine — limitations
Web content — benefits
Web content — risks
Tap a chip, tap a square. In each square, say if it is “in the video” or “my inference”.
How can we access reliable health information with less effort — in the age of telemedicine and AI?

Everyone speaks: 30 seconds to prepare alone → A speaks 45 seconds, B notes the evidence → swap roles → both revise → two students share with the class.

Use the evidence frames. You may say “I think … because the video says …” — the reason is the point.

The video says that … According to the video, … The speaker warns that …

My route — my own order

Which resource first, which next, and when to move on? Any order is fine — if you can give a reason. (Going straight to a doctor is also allowed.)

Self / peer rubric

Score yourself or your partner on each line — 1 (just starting) to 4 (secure).

8

Build it — say the whole thing

Three frames from today · tap the words into order · one student, one sentence

Each row is one complete sentence you can use in your answer today. Tap the word blocks in order. A wrong block goes back — try again. One student, one row — then pass the mouse to the next person.

DONE 0 / 3 — when all three are built, the class has three complete frames for the exit ticket.
9

Act it out — book, describe, decide

Three calls, one patient · tap a role, then tap your lines

Someone is ill and does not know where to go. Act the three steps with the screen — book it · describe it · decide where. Every line you tap is a line you can really say.

Lines used this round: 0 · Reset clears the round for the next pair.
10

Team relay — four groups, one board

One student per task · tap to light a group · the fastest board wins

Four groups. Each group sends one student at a time to finish one task on this board. Tap the task when it is done — the bar at the top shows how many of 12 are finished.

0 / 12
No pen, no paper: the board keeps the score. If a group answers in Chinese, ask for it again in English before you tap.
11

Your route — and homework

Exit ticket · an information-check card

Exit ticket

One sentence, English: how will you combine these resources to stay reliable without wasting effort?

Homework — an information-check card

Imagine Lin's cousin (fictional): a headache for two days, and two different explanations online. Make him a small information-check card with four lines:

1 · the source I would check — 2 · one benefit of that source — 3 · one limitation or risk — 4 · one question to verify it —
Use ideas from the video where you can — and label them “in the video” or “my inference”.
