Teacher Guide: Ethics and Implications

Student topic: Ethics and Implications IB Syllabus: A4.4.1, A4.4.2 (Discuss, AO3, SL + HL) Estimated periods: 4-5 across both pages

Ethics under the current syllabus is core, not an HL extension, and it is examined with the Discuss command term. That single fact should shape how you teach the whole topic: a list of dangers is a low-band answer no matter how long. Everything drives toward one skill – two developed sides plus a conclusion that weighs them.

Teaching sequence

Teach the two pages in order; the second reuses the first’s vocabulary and scales it up.

Ethics of Machine Learning (A4.4.1, 2-3 periods) – the nine ethical dimensions, where bias comes from (training data), online communication ethics, and the Discuss structure. System-level analysis.
Computing in Daily Life (A4.4.2, 2 periods) – pervasive computing, surveillance, digital divide and equity, emerging tech (quantum, AR/VR, pervasive AI), and reassessing guidelines as technology advances. Society-level analysis.

The one skill that matters

Both pages assess Discuss (AO3). The transferable structure to drill:

One side, developed (state a point, explain why it matters here).
The other side, developed, using named concepts (privacy, consent, bias, accountability, equity, surveillance).
A conclusion that weighs your own points – for these questions, usually a calibrated “acceptable only if [conditions]” rather than a flat yes/no.

The top-band self-check students should run before stopping: detailed accurate knowledge · correct terminology throughout · balanced analysis of more than one side · conclusion linked to the analysis.

Cross-cutting misconceptions to pre-empt

“A mathematical model is objective.” (The maths is fine; the data carries the bias.)
“Privacy means keeping secrets.” (Harm comes from data leaving the context it was given in.)
“Surveillance/automation is simply good or bad.” (Both genuinely help and harm; the mark is in the calibrated trade-off.)
“Discuss means list.” (It means argue two sides and conclude.)

What each sub-guide contains
