I have very strong interest in researching effective approaches in teaching and fine-tuning American college students' pronunciation. Being inadequately nicknamed "the tone police" by students, I devote a good deal of time on finding more effective ways to help students break away from the influence from their native language of English. I am also interested in finding ways to better introduce the nuances between phonemes in Mandarin Chinese and American English.
Chinese grammar is another area that I am fond of exploring. I like studying grammatical features that present the most challenges to both the students and the instructors, e.g. Chinese adverbs, all complements, aspect words "le," "zhe," and "guo."
