What makes A4.4.2 distinct from A4.4.1
A4.4.1 evaluates a single system. A4.4.2 evaluates integration at the scale of society: what changes when computing is everywhere, not in any one app. The same Discuss skill applies, but the units of analysis are different – communities, workforces, rights, access – and the strongest answers almost always resist absolutes, because pervasive computing genuinely helps and harms at the same time.
The page’s spine is one idea worth naming explicitly to students: ethical guidelines must be continually reassessed as technology advances. This is the only A4.4.2 must-include with almost no concrete real-world anchor by default, so it needs deliberate teaching (the deepfake-vs-old-law example is the cleanest hook).
Lesson Plan
Period 1: Pervasive computing, surveillance, privacy, equity
| Phase | Time | Activity | Student Page Section |
|---|---|---|---|
| Hook | 5 min | “List every device near you right now that contains a computer.” Students undercount; reveal the hidden ones (watch, earbuds, card, car key). Name this pervasive computing | Pervasive and Embedded Computing |
| Teach | 10 min | Three features that create the ethical weight: always-on, hard to opt out, data combines. Smart-city example | Pervasive and Embedded Computing |
| Teach | 10 min | Surveillance: targeted vs mass; privacy as context, not just secrets | Surveillance, Privacy, and Individual Rights |
| Teach | 8 min | The digital divide and equity: access, affordability, skills, quality. Online-only-services example | Equity and the Digital Divide |
| Quick Check | 7 min | Q1-Q3 on EduCS.me | Quick Check |
Period 2: Emerging tech, reassessing guidelines, and the Discuss skill
| Phase | Time | Activity | Student Page Section |
|---|---|---|---|
| Recap | 4 min | Cold-call: targeted vs mass surveillance; one layer of the digital divide | – |
| Teach | 12 min | Emerging tech: pervasive AI, AR/VR (eye-tracking, bystander consent), quantum computing (encryption threat). Keep it to new questions raised, not technical depth | Emerging Technologies |
| Teach | 8 min | Reassessing ethical guidelines as living documents. Deepfake-vs-old-law example. Then work + globalisation in brief | Reassessing Ethical Guidelines; Work and Society |
| Quick Check | 6 min | Q4-Q6 on EduCS.me | Quick Check |
| Practice | 15 min | Extension 5 (smart-city Discuss, 8 marks) – draft the three-part skeleton, then write the conclusion in full | Practice Exercises |
Teaching notes:
- Resist absolutes is the headline skill here. “Surveillance bad / convenience good” both score low. Model the calibrated move: a named benefit vs a named cost → conditions under which the trade-off is acceptable.
- Quantum computing has almost no settled ethics – that is the point, and it sets up the “reassess guidelines” theme. Don’t get pulled into qubits; the assessable content is the encryption threat and the equity/first-mover concern.
- The digital divide has layers. Push students past “some people don’t have computers.” Affordability, skills, and quality are separate, examinable layers; a strong answer names which one a scenario raises.
- Privacy-as-context is the most useful reframe on the page. Students think privacy = secrets. The stronger idea is that harm comes from data leaving the context it was given in (medical detail → insurer). This unlocks better answers across the whole topic.
- Two-population framing for work. Steer students away from “robots take all jobs” toward “who is displaced and needs support vs who gains – and who bears the cost.”
Differentiation
Supporting students who struggle:
| Strategy | When to use | Example |
|---|---|---|
| Concept cue cards | Cannot recall the concepts | Cards for digital divide, mass vs targeted surveillance, equity, pervasive computing – with a one-line test question each |
| Scenario → concept sort | Overwhelmed by the breadth | Give 8 short scenarios; students tag each with the concept it raises before any writing |
| Conclusion sentence frame | Can’t reach a verdict | “This benefits __ but excludes/harms __, so it is acceptable only if ___” |
Extending stronger students:
| Strategy | When to use | Example |
|---|---|---|
| Force the trade-off | Writes one-sided answers | “Defend surveillance for a real safety gain, then defend the objection – then decide” |
| Reassessment design | Grasps the living-document idea | “Draft three rules a city should adopt before deploying face recognition, and say how it should review them” |
| TOK / global link | Philosophically minded | “Whose ethics apply when my data is processed in another country with weaker protections? Is there a universal standard, or only local ones?” |
IB exam relevance
- Discuss the ethical aspects of [integration scenario] – the headline AO3 question. Needs both sides + a conclusion stating safeguards/conditions.
- Distinguish targeted vs mass surveillance; define the digital divide and its layers – lower-mark precision questions.
- Explain the “reassess guidelines as technology advances” principle with an example – a likely discrete question because it’s an explicit must-include.
- Top-band checklist (same as A4.4.1): detailed accurate knowledge, terminology throughout, balanced analysis, conclusion linked to the analysis.
Answer Keys
Non-programming: keys give indicative content and marking notes. For Discuss/Evaluate, mark the quality and balance of the argument and the linkage of the conclusion, not which side the student takes.
Quick Check (on-page MCQs)
| Q | Answer | Key teaching point |
|---|---|---|
| Q1 | b | Bystander problem – data collected on people who never opted in |
| Q2 | c | Mass surveillance – everyone treated as a suspect by default |
| Q3 | a | Digital divide / equity – online-only excludes the unconnected |
| Q4 | d | Quantum computers threaten today’s encryption |
| Q5 | b | Guidelines must be reassessed as technology advances |
| Q6 | c | Automation = two-population question; who bears the cost |
Match the Concept (fill-in)
digital divide · mass surveillance · quantum computing · consent · reassessing ethical guidelines
Marking note: accept “informed consent” for the AR item; accept “living guidelines / updating guidelines” for the last.
Core 1: Define the digital divide + two layers (4 marks)
1 mark definition + 1 mark per layer with example (capped at 2 layers + their examples).
- Definition: the gap between those with good access to computing and the internet and those without.
- Layers (any two): access (no device/connection – e.g. rural area with no broadband); affordability (infrastructure exists but data/devices cost too much); skills (has access but can’t use it safely/effectively); quality (a slow capped mobile link is not equal to home broadband).
Marking note: “some people don’t have computers” alone is the definition mark only; the layer marks need named, distinct layers.
Core 2: Distinguish targeted vs mass surveillance (4 marks)
- Targeted: watching a specific person for a specific, justified reason, ideally with oversight/authorisation.
- Mass: watching everyone by default, storing data in case it’s useful later.
- Why mass attracts more objection: it treats an entire population as suspects, creates a large store of data open to future misuse, and has a chilling effect on free behaviour.
Marking note: 2 marks for a clear distinction, 2 for the justified reason mass is more controversial.
Core 3: Why pervasive devices raise extra privacy concerns (4 marks)
Indicative (any two developed): always-on sensing means continuous data collection; affects bystanders who never consented and can’t opt out; the data from many devices combines into a detailed profile none of them implied alone. Contrast with a single offline device that senses only when used and stores data locally.
Marking note: reward the combination and bystander points specifically – they are what make pervasiveness distinct.
Extension 4: Ethical guidelines as "living documents" (6 marks)
Indicative: guidelines/laws are written for the technology that exists when made; technology advances and old rules fail to cover or misjudge new situations; therefore guidelines must be reviewed, informed by those affected, and updated before harm becomes widespread. Example: laws on fraud/defamation predating deepfakes left victims poorly protected until revisited; or copyright predating models trained on millions of works; or encryption standards threatened by quantum computing.
Marking note: 6 marks need the principle plus a concrete example of tech outpacing its rules; the principle alone is mid-band.
Extension 5: Smart-city cameras/sensors -- Discuss (8 marks)
Mark on balance + linked conclusion. Indicative content:
- For: efficient traffic/lighting/energy management; faster emergency response; crime deterrence; data for better planning.
- Against: privacy (continuous tracking of movement); mass surveillance and chilling effect; consent (residents/bystanders never agreed); equity/individual rights (who is watched more; data misuse); security of the collected data.
- Conclusion: a defended position with safeguards – e.g. acceptable only with data minimisation, strict retention limits, independent oversight, transparency to residents, and a ban on repurposing the data; otherwise the surveillance cost outweighs the efficiency gain.
Bands: one side only = lower; both sides, weak conclusion = middle; both developed + linked conclusion + terminology = top. Requires ≥3 concepts and prose.
Challenge 6: All-online public services -- Discuss (10 marks)
Indicative content:
- For: efficiency, lower cost, 24/7 access, faster processing, less duplication.
- Against: digital divide (excludes the unconnected, low-income, elderly, rural – exactly those most dependent on public services); surveillance (a single platform links all of a citizen’s interactions with the state); individual rights / single point of failure (outage or breach affects everything); accountability if the system errs.
- Conclusion: calibrated with safeguards – e.g. acceptable only if an offline/assisted alternative is retained, data is siloed rather than linked, and accessibility is designed in; “online-only” specifically is hard to justify because it converts a convenience into exclusion.
Marking note: top band needs the digital-divide harm developed and a conclusion stating conditions, not a flat verdict.
Challenge 7: AR/VR benefits vs costs -- Evaluate (10 marks)
Indicative: weigh learning/productivity benefits (immersive training, remote collaboration, accessibility gains) against costs (intense sensing incl. eye-tracking → privacy; bystander consent for AR cameras; psychological effects, addictive design, blurring real/simulated, especially for young users). An Evaluate reaches a recommendation against criteria – e.g. benefits justify adoption in bounded educational/professional settings with privacy safeguards and age limits, but not unregulated consumer saturation.
Marking note: must reach an explicit, justified recommendation; balanced discussion without one caps below top band.
