Over the last two decades, English education in Korean secondary school contexts has exclusively focused on the receptive skills such as listening and reading skills. With the emergence of communicative competence and a new proposal of National English Ability Test, secondary schools in Korea are required to prepare for the development of a speaking skill. The purpose of the paper is to design and provide a teaching model for developing a speaking skill in Korean EFL secondary schools. First of all, the researcher gathered and analyzed the data from one of high schools in Korea in terms of the curriculum, a model for teaching a speaking skill, and classroom lesson. Based on the Willis's (1996) task model, the researcher provided a pedagogical framework for teaching a speaking skill with the applications of the focus-on-form (e.g., dictogloss), off-line concordancing program, and performance-oriented evaluation to a model, followed by a sample lesson at the appendix. A need for the future research using the framework at secondary schools was suggested. (Seoul National University of Science & Technology)
