I think once the student realizes her blocks won't match up because of the seams not being accurate she will know then how important it is. It's up to her unless you sew it for her.
I agree with this process completely and try to do it each time I'm sewing. Read TRY! Sometimes I forget. Apologizing for not having read all the posts...but if possibly you work with this student on a small, complete project (i.e. table runner), having her try to get all the blocks to line up will emphasize the importance of accurate cutting and sewing. Seeing how things DON'T line up might be the big AH HA that will get the point across. Did for me.
