There are more. For example, the issues involved with student behavior are totally different now than they were in the past. 50 years ago, the most common behavior problems were talking and chewing gum in class. Students respected their teachers and obeyed them and the rules. If they didn't respect the teacher, they at least showed them respect. There was an occasional physical fight, but nothing that was not handled quickly and effectively. Standing in corners, missing recess and spanking were acceptable punishments. Now, behavioral issues can involve almost anything from showing teachers disrespect to the most dreaded of all, school shootings.
