This paper comes out of concerns about teaching English writing to vocational high school students in EFL learnersâ€™ context. This study points out how the process-product hybrid approach affects studentsâ€™ writing skills in solving some complex problems in order to generate deep comprehension of writing. In this study, quasi-experimental research was applied to measure the studentsâ€™ writing improvement by collecting the data from instruments which covered pre-test, post-test, and questionnaire. The findings showed that studentsâ€™ writing skill improved significantly. It also revealed that almost all of the students responded the statements positively and they believed that this approach can help them in improving their writing skill since it gives full comprehension of writing and serves more interesting teaching learning activities. Therefore, this integrated approach has become the most recommended approach for teachers to improve studentsâ€™ writing competences.Keywords: process-product hybrid approach, teaching English writing, studentsâ€™ writing skills.
