The purpose of this study is to set up a teaching model of English for Specific Purposes (ESP) for liberal education, and to verify its effectiveness by developing class materials for English for Advertising and Public Relations and applying them directly in ESP classes. For the purpose of this study, a teaching model of ESP for liberal education was designed in three stages: input – content-based language instruction – task and project. The Advertising and PR English textbook is composed of seven themes, two units for each subject, and each unit consists of vocabulary, the main content and group activities. In order to examine the effectiveness of the model, a total of twenty-six university students who participated in the classes of English for Advertising and PR were questioned in the survey. The results of the questionnaire showed that the participants showed the highest satisfaction with the teaching method, and were also quite satisfied with small group activities and Havruta learning activities. In particular, they identified with the fact that they learned terms related to their major which helped them obtain professional knowledge. However, low satisfaction was expressed with the difficulty of the class textbook. Practical implications for effective ESP education were suggested.
