During the KPop in Science unit I have been explicitly teaching how to write well.
Not how to write well in science.
How to write well.
We started with "writing with precision" and I used an (only slightly) adjusted lesson with Y9, 11 and 13. My friend Kata (who attended the same writing conference with me) also used these slides with her tutor, Y9, 12 and 13. We share some of the Y11's and 13's, and they recognised the learning from their other subject.
This is the presentation I used with Y9, at the end of their "forensics" unit.
