Thank you for this comment. It's given me much to think about,
particularly as it is based on your experience as an educator. I've
raised an issue based on your comment.

I'm also taking the liberty, I hope no-one minds, of sharing some
further ideas with you off-list. (They will become public in due
course.)

with best wishes
