The map you started on Day 1 is complete. Close the loop, then take the Unit 8 test. This page is everything you can do before it — there are no test questions here.
Practice questions here are AP-TESTABLE. The test checks only CED material — no machine-learning mechanics.
No new reading. The fastest revision: rerun the 8.10 gym and read every distractor explanation.
Every region is lit. People → Bits → Programs → Internet → Security → Big Data → Impact — and Impact loops back to People. You built this, one unit at a time.
| Don’t | Do |
|---|---|
| “It’s bad for people.” | Name the mechanism: what the system does, and how that causes the effect. |
| Argue one side. | Both columns — beneficial and harmful — plus one unintended effect. |
| “Bias means someone meant it.” | Bias is often unintentional: the data, the design, or the use. |
| “More data fixes it.” | More data from the same skewed source keeps the skew. |
| “Free to use, so no credit.” | Most licenses still require attribution — and the Create PT always does. |
| Pick the boldest answer. | Cross out always, never, eliminates. Pick the one that says how. |
The test: about fifteen multiple-choice scenarios in Big Idea 5 style — effects and unintended consequences, sources of bias, the digital divide, crowdsourcing, licensing and attribution, and Unit 7 safe-computing items — plus one written response that analyzes a computing innovation you haven’t seen before, using the 8.6 frame.
Twenty terms. Read the definition, pick the term. Misses come back at the end.
Six BI5 scenarios. None is on the real test.
Prompt. Video doorbells record everyone who walks past a home and can share clips with neighbors through an app.
(a) Describe one beneficial effect and explain how the innovation causes it. (b) Describe one harmful effect and explain how. (c) Identify one effect its designers probably did not intend. (d) Name one group affected differently from the doorbell’s owner, and how.
□ (a) Benefit with a mechanism. e.g. owners see who’s at the door remotely, so they can avoid opening it to strangers or check on deliveries.
□ (b) Harm with a mechanism. e.g. it records people who never agreed to it — neighbors, delivery workers, kids walking to school — and the clips can be stored and shared.
□ (c) An unintended effect. e.g. shared clips feed neighborhood suspicion of people who “look out of place” — a bias in how the results are used (8.4).
□ (d) A different group, specifically. e.g. passersby have no say and no access to the footage; renters may be recorded by a landlord’s camera.
□ Every part says how. “It invades privacy” alone earns little. Say what is recorded, of whom, and what happens to it.
