Yunwen Su (Ph.D. Indiana University Bloomington), section head of the Chinese program, researches passionately in the field of applied linguistics. Specifically, she has interests in acquisition, pedagogy, and assessment of second language pragmatics. She has been primarily studying the pragmatic aspects of second language production in both English and Chinese at the interactional level. She has also been extracting linguistic resources that contribute to successful human interaction (e.g. pragmatic routines, discourse patterns), and studying how learners use them in context. She considers research design and data interpretation from an assessment perspective, highlighting the importance of the authenticity of the elicitation tasks and the validity of inferences we can make about learners’ pragmatic performance in the real world. She has published in Foreign Language Annals, Language Learning and Technology, the International Journal of Language Testing, and edited volumes. She teaches courses throughout the Chinese language, culture, and linguistics curriculum. She is currently working on a project that examines learners’ perception of ritual and sincere refusals of invitations and offers in Chinese.
