By getting punished another way other than ASI. You don't need to be held after school to "learn your lesson". You can learn your lesson by getting a deduction or not being able to do something that the class is doing. ASI doesn't do anything for you

The punishment doesn't have to be an ASI. It could be minus 5 points for everyday that he/she doesn't get the assignment, or it could be a 0 in the grade book until they turn it in. Being held after school doesn't teach responsibilities. Giving real consequences does.

No. Because ASI doesn't really do anything for them. It's just a place they have to stay for extra time. They might have a good reason for not turning in the work. ASI just tells them that it was a mistake. It doesn't prevent it from happening again.
