Teachers need to know the types of ethical boundaries that arise when teaching in order to prevent themselves or their students from being harmed in any way. Teachers need to be able to mask and control their emotions, realize when to let go, and avoid cursing in front of their students. Teachers should also not reward or punish a student based on their relationship with the teacher, their popularity, or favours done by the student or teacher. Talking about highly personal subject matter with the students or engaging in conversations with students when the student is sharing information that does not benefit the student crosses ethical boundaries.
