This document discusses different approaches to teaching skills, including:
- The UK curriculum says skills should be taught through substantive science content.
- US science standards integrate skills with content in "learning performances" that construct explanations based on evidence.
- Research finds that skills should be broken into components, taught individually with modeling and focused practice, and integrated across topics with lots of practice.
- In practice, skills often lack explicit teaching and are marginalized in curriculum time due to an "expert blind spot".
