Corrections
Guiding question: Can you retrieve across topics when the order gives you no clue what concept comes next?01
Today’s destination
By the end of class, you should be able to…
01
Simulate mixed retrieval
Answer without topic headings giving away the category.
02
Use exam discipline
Read every stem and eliminate distractors deliberately.
03
Correct by concept
Record why wrong answers were tempting.
04
Build a final priority list
Identify the smallest set of topics that need more work.
Success check: Use accurate terminology, then apply it to unfamiliar design contexts.

Correct + confident
Good—still revisit later through spaced retrieval.
Correct + guessed
Treat as a gap. You may have recognized a distractor pattern rather than understood the concept.
Incorrect
Write the exact concept contrast and re-answer a fresh example.
Confidence matters as much as score10

Why is “recyclable” alone not proof of circularity?
Circularity also depends on system design: longevity, disassembly, repair/reuse/reconditioning, recovery, waste/pollution elimination and renewable energy—not merely material recyclability.
Why is a formal orthographic drawing not automatically a good ideation tool?
Formal drawings communicate precise geometry well, but early divergent ideation often benefits from faster informal/iterative sketches that are easier to change.
Why can user feedback conflict with performance data?
Users may prefer one feature while measured performance suggests a trade-off; designers evaluate both against prioritized specifications and user needs.
