As a parent of a middle schooler & as a college professor I'd love to see more students learn: writing is a thinking process. You don't think then write, which leads to this idea sentences should emerge fully formed from your brain. They go together & inform each other.

I mean yes, thinking precedes writing, but writing is also thinking. So getting something down is crucial to developing your thinking. Then you revise it. My kid gets these worksheets and feels she needs to write these perfect sentences and I'm all PLEASE WRITE GARBAGE FIRST.

Or my students think they should read a paper & churn out a reflection. If you took no notes and did not reflect during the reading, the reflection will be word salad. Which is ok if you revise it, but not ok if you submit as is. (And yes I teach this I don't assume they know.)
