The Chinese classic 'The Great Learning' presents a guideline in which direction we should go for the character education and the realization of a just society. It conveys the message, 'Everyone must remain at the level of goodness for our community based on training our own mind and body.' Goodness is a generic concept that means universal truth in the right direction. This study aims to present the direction of communication education for how everyone should stay in goodness. Communication education about goodness could be conducted as follows. Based on the theory of interpersonal communication and persuasive communication, first the abstract concept of goodness is understood, brainstorming and schema activity for the good are performed for true communication, and then the teaching and learning method combining debate, flipped learning, and writing could be utilized. It is difficult to provide communication education with the message of goodness with students who have grown up on the basis of comparatively cramming education. However, through communication using discussion, a paradigm shift in education will take place, and it will not only help form human relationships, but also recognize the importance of the meaning of the community in the society in which we live, and ultimately it will help foster character.
