This paper reports preservice teachers' knowledge and understanding about genre-based pedagogy in the curriculum and its implementation in their EFL classrooms. Six participants who were taking their teaching practicum program in two different state schools took part in the study. Employing a case study design, the data were collected through questionnaire, observations, interviews, and document analysis (lesson plans). The findings show that the preservice teachers had varying degrees of knowledge and understanding of what genre-based pedagogy is and how to apply it in the teaching and learning. All of them, though, believe that genre-based pedagogy is very useful and applicable in EFL teaching and learning. Out of the six participants, four employed the pedagogy in their classroom teaching and learning. There is, however, a gap between what the preservice teachers know and understand about genre-based pedagogy and how they apply it in the classroom. Most of the preservice teachers skip the most important part in genre-based pedagogy, namely building knowledge of the field. They also do not give feedback to their students' writing. These findings have some implications for the English teacher education in Indonesia. Teacher education institutes should pay more attention on preservice teachers' practices in the classroom. Cooperation between the teacher supervisor, lecturer, and preservice teachers is really needed.Keywords: genre-based pedagogy; preservice teachers; national curriculum Genre-based pedagogy, or genre-based approach, has increasingly gained popularity among teachers who teach writing in English, particularly in EFL and ESL classrooms. Hyland (2007) asserted that genre pedagogies help teachers in grounding their courses in the texts that their students will have to write in their own target contexts. Studies show the effectiveness of genre pedagogies to teach writing in different countries. In Iran, for example, genrebased pedagogy is effective for teaching academic writing because of its early stage of presentation process (Alidoost et al., 2014). In Korea, explicit writing instruction in genre-based pedagogy was effective to improve students' writing, and the students showed positive attitude towards writing (Bae, 2012). Meanwhile, in Thailand genre-based pedagogy is claimed to show promising results in terms of students' improvement in writing due to its helpful stages (Chaisiri, 2010). Similarly, Wang (2013) claims that the approach was effective in increasing EFL writers' awareness of genre and competence in writing.In the case of Indonesia, where English is treated as a foreign language, genre-based pedagogy has been incorporated into the national curricula prevailing in the schools today (the 2006 schoolbased curriculum and the 2013 curriculum) through the inclusion of different kinds of texts to be produced by students in written and orally. Students are expected to develop their language skills (listening, speaking, reading and writing) by ways of practicing the texts such as na...
