My studies at Ohio State provided me with both theoretical knowledge and valuable first-hand experience. My professors encouraged me to explore the natures of L1 and L2 acquisition. They also enlightened me to use diversified and multicultural perspectives to design a course. Specifically, I was trained to integrate the information of learners’ linguistic knowledge, schooling experience, and cultural background into the course design. Throughout the field experience course, I also had chances to observe, record and analyze language learners’ behaviors by taking the ESL courses and online tutorials as an observer where I obtained new ideas in foreign language teaching. What I have gained at Ohio State well prepares me for my further career as a teacher.
