Changes in assessment practices in the direction of assessment for learning (AfL) can be a powerful force to enhance student learning. This article presents a case study of teacher learning in an AfL project in Hong Kong. In the Project, AfL strategies were adopted in Chinese Language and English Language classrooms at the junior secondary level. By examining subject leaders' and classroom teachers' experiences with the project reported in interviews, the paper enriches our understanding of the variations in the subject department contexts of teacher learning, the situatedness of teacher learning in terms of knowledge about student learning, understanding of AfL and curriculum leadership, as well as the relationship between teacher learning and changes in assessment practices. The article concludes with suggestions on fostering subject departments to be expansive environments for teacher professional learning and to be a vehicle of internal change, alerts the importance of integration of AfL into teachers' pedagogical content knowledge and the subject curriculum, and highlights the cultural dimension as an issue for further study in AfL.

The primary focus of this study is the use of portfolio development in an in-service teacher education course that aimed to help primary school teachers develop a better understanding of, and ability to implement, an innovative teaching approach--namely, task-based learning (TBL)--in Chinese language. It explores the impact of portfolio development on teachers' understanding of TBL and their views on portfolio development. The research employed a combination of quantitative and qualitative methods, with data being collected through questionnaires and interviews. The findings showed that the portfolio development had a positive impact on teachers' understanding of, attitude to and confidence in applying TBL. The processes encouraged teachers to think through their practice, to become more conscious of their teaching. On the basis of the major results, this study suggests improvements for the future use of portfolio development for in-service teacher education courses and for teachers' professional development.
