The purpose of this study is to describe, in a situation where necessity and justification of audience consideration in Korean education have been agreed, what the aspects that high school students as speakers, who recognize audience, carry out audience consideration are. In preparing and performing persuasive speaking of authentic male high school students for formal situations, they recognized the importance of considering audience and could describe a variety of characteristics of audience who they will face. However, they did not know how to configure persuasive discourse suitable to the characteristics of the audience as well as did not explicitly state the location or method where the characteristics of the audience have been significantly reflected in the persuasive discourse they configured. Audience consideration is a concept encompassing the process that a speaker ‘construct audience’ and ‘proceeds to configure an appropriate discourse according to such construction’. With the result that the study observed and analyzed the configuration and interaction of the persuasive discourse of high school students, some implications necessary for enabling speakers to effectively consider audience in persuasive discourse education could be derived. First, students need to be able to experience the presence of ‘audience’ more concretely and authentically. Second, they should connect ‘the characteristics of audience speakers construct’ and ‘configuration and strategy of discourse according to audience construction’ more meaningfully. In addition, considering authentic aspects of audience that speakers face in discourse situations, an education that the characteristics of audience can be considered in combination is necessary.
