Did the database path prove successful for student worksheets?
I use Mahara in a similar way. I provide the template, the questionnaire in your case which the students copy to their own portfolios. They then fill it in and I can give feedback, or the students can form small groups to give feedback first, followed by my feedback.
Students link their pages to Moodle when they are ready for me to give my input.
It's a great approach since the questionnaire remains theirs along with the feedback etc.
Just a thought.
