The problem is clear. As a teacher you have no authority and no one supporting you. The parents don’t care and the administrators will not discipline the trouble makers. I think my friend sank into a feeling of hopelessness. The kids were so far behind academically that his lesson plans were not applicable. Try teaching a physics class when most of the kids can’t even add or subtract.
Back when I was going to school,only the top students took higher level Science or Math classes like Physics and Intermediate Algebra.
Now,these classes,watered down greatly,are required for graduation in most urban districts.
And 75% of the kids haven’t the slightest idea of the subject matter and are failing right and left.
