Does teaching programming actually teach programming — and does the method matter? · computer-science · ages 5–18

Unassisted discovery loses to explicit teaching; well-scaffolded guided discovery beats both. The operative variable is guidance, not ideology.

Explicit instruction vs discovery/inquiry — how much guidance? · instruction-style · ages 4–18 · method

Novices learn faster studying solutions than solving problems — then the effect reverses with expertise. Use worked examples early; fade them.
