Here is an idea... What if during the grading process we can use the rubric as checking off skills (e.g. future tense, relative pronouns, etc...) so that if a student makes a mistake on xyz, we can send them back to the relevant part of the module to have them review something. In other words, there would be a link to the relevant activity(ies) in a particular module that the student could click on when they review their work after it has been returned. Maybe when we meet, we can talk more about this in detail.
