Answer: Grading and discipline
Explanation: One of the legal ethical issues that exist when it comes to teaching are, for example, issues because of discipline, social diversity, ethnic diversity, choice of teacher and grading.
For me, the greatest concern are grading and issues of discipline. Some children who doesn't study enough are sometimes accepting those grades badly and then, they are telling the parent's that that is the teachers fault. This is an issue because a lot of parent's are believing their children even if they don't know that they are right or wrong and then they are behaving badly against the teachers.
Discipline is also an issue because the teachers can't calm some children and make them to behave good and peaceful. It is also a dangerous issue because of the fighting.
