In second language writing, not much attention has been given to the English as a foreign language (EFL) primary context. This short research report describes the implementation of a writing curriculum project in a primary school in Hong Kong, where a team of EFL teachers attempted to overhaul the traditional product approach and implemented process-genre pedagogy collaboratively. The change initiative has brought improvement to students' motivation in learning writing, enhanced their writing performance, and brought honor to the teachers and their school as they were awarded a prestigious teaching excellence award by the Hong Kong government. This report presents the outcomes of the project and discusses the factors that facilitated change, providing useful tips to help all other teachers working in similar contexts bring improvement to the learning and teaching of writing.
