When working with modal verbs of command in a negative form (mustn’t, don’t have to, etc.) I decided to make a ‘traditional’ explanation, so I just explained the rule to my students (I did it via ENV though). There are several reasons for doing so. First of all, I think this part is more difficult so it requires more time. Since the test time was approaching I was sure we will not manage to build the rules. In addition, I saw many problematic areas in the new group of modal verbs, so it required much more preparation on behalf of me to make clear procedures for working with these modal verbs. I didn’t manage to come up with clear procedures, thus, avoiding the situation of too much confusion, I decided to explain the rule.
In any case, I managed to give the post-test for the modal verbs so students could have measured their progress. In addition, during our work, I was all the time asking students to count how many correct answers they have, thus trying to make them monitor their progress.

Another question I've got is why the model for negative modals should be different from the model for the same modals when used in the affirmative meaning. It's not very logical, is it?
Anyway, can I ask you how you explained the rule to the students? How did the ENV look like?
I made the ENV rule and presented it as a ready-made rule. You can see the model published by one of my students - http://at-eportfolio.wikidot.com/m-v-obligation-necessity
Re different negative models, I meant that the meaning of 'I must go' isn't the opposite of 'I mustn't go', is it?
