The question can be considered simple, but for me, the answer is not easy. The answer should not be just another ethic course. In this way, morality is probably not different from medicine or economics or anything else: It would remain theoretical. Theory may (or may not) be the foundation for the later training of a skill, but most often theoretical knowledge is transformed into practical skill by *application* or *exercise*. But how to do this for morality? Or is moral behavior not teachable at all?
