To cater to the varied learning backgrounds, needs and diverse proficiency levels of the non-Chinese background students at the HK University of Science, since June 2021 onwards, the Center for Language Education has been designing the new Chinese curriculum. The new curriculum offers three speaking and listening courses and two reading and writing courses based on the results of the needs analysis. In order to boost students’ spirit of inquiry and facilitate collaborative and self-directed learning, blended learning is adopted in the instructional design of the five new courses. This study will introduce the blended learning design of the five courses including the course design process, the models and technology used, and will explore the challenges that the course developers are meeting in the design process.
