Taking Stock of a Genre-Based Pedagogy: Sustaining the Development of EFL Students’ Knowledge of the Elements in Argumentation and Writing Improvement

The capacity to make effective argumentation in English writing is considered as a crucial ability in the field of second language writing. Currently, Chinese teachers of English as a foreign language (EFL) adopt the product approach to teach argumentative writing, in which they stress the mode of learners’ written production and show little concern with cognition. For students’ sustainable development in argumentation skills, teachers are encouraged to employ a genre-based approach to cultivate students’ knowledge about different elements in argumentation. However, few empirical studies have investigated the efficacy of such classroom-based instruction on learners’ comprehensive development in EFL writing, including their knowledge about writing and performance in producing argumentation. This is particularly the case with reference to Chinese students learning to write argumentative texts in EFL. To fill the research gap, this quasi-experimental study was conducted with 74 EFL sophomores, who were randomly allocated to either an experimental group or a comparison group. The experimental group received a genre-based writing approach, while the comparison group experienced their conventional writing instruction. Students’ changes were analysed using pre- and post-writing test measures, open-ended questionnaires, and stimulated recall interviews. Our findings revealed more changes in the experimental groups’ knowledge about argumentation following the genre-based writing treatment than the comparison group. Specifically, the experimental group’s progress was obvious in the way they displayed their knowledge of the structure of discourse moves and of language features specific to the argumentative genre. They began to express their knowledge of the content, process, intended purposes, and audience awareness towards producing more genre appropriate texts in argumentation. They also showed enhanced self-reflection on their knowledge of argumentation. In addition, the genre-based approach had a positive effect on the experimental group’s argumentative writing development, as evidenced in their use of discourse move structures and their overall writing quality improvement. The conventional writing approach was not as effective in helping students to write an argumentation. Writing proficiency effects were observed in terms of the extent to which the students were developed. Pedagogical implications and limitations are also discussed.
