There is an ongoing debate about whether teachers should shape students' moral judgement or restrict their role to academic instruction. While some argue that ethics education is essential for social order, others believe this responsibility belongs primarily to families rather than to teachers. In my view, teachers should contribute to the moral development of students alongside academic teaching, because schooling naturally combines knowledge with character.

Supporters of a moral role for teachers emphasise that schools are major environments where children learn to behave through daily interaction with instructors and peers. Teachers regularly handle discipline, collaboration and fairness, which inevitably involves ideas of right and wrong. For example, when instructors address bullying or cheating, they must explain why such conduct is wrong rather than merely enforcing rules. Because students spend substantial time in schooling, consistent guidance from teachers can reinforce respectful behaviour and social responsibility.

By contrast, opponents argue that teachers are trained mainly as subject specialists, not as moral authorities. They claim that values vary across cultures, so schools risk imposing beliefs that conflict with what children learn at home. This concern is reasonable, because excessive moral instruction could divert students from academic goals. However, teaching basic principles such as honesty and accountability does not impose ideology on students. Instead, it supports effective learning and orderly classrooms.

Overall, although academic achievement is a central purpose of education, it cannot be separated from how students behave. Teachers should not replace parents. Yet they should clearly share responsibility for guiding the right and wrong judgement of children, thereby creating disciplined and supportive learning environments for every student.
