As I am sure you have already thought through, there is a trade-off here:
- If Moodle generates the 'What is required' list automatically, then it is guarantted to match the acutal settings, and teachers don't have to remeber to make this clear.
- But then this slighly technical information is always present on-screen, and teachers have no control of how it is phrased, which they would do if we just left it to teacher to explain what they want in the activity description in language that makes sense for their class - but they might forget.
So, I don't have strong feelings one way or another. Neither option is clearly best all the time.
