This portfolio is a collection of artifacts, experience, and reflection I have during the two-year learning at Peabody College, Vanderbilt University. The paper consists of three parts. First, I introduce my teaching philosophy which highlights teachers’ caring for learners, constructivist learning, strategic scaffolding, and influence of L1 on L2 acquisition. With the guidance of EFL standards, I provide six artifacts as supportive evidence to demonstrate my understanding of every TESOL domain in four professional knowledge areas: the learner, the learning contexts, curriculum, and assessment. Furthermore, reflecting upon all the work I did, I explain how I applied theories to my practical teaching. The last section elaborates on the challenges I might encounter in my future teaching context and possible solutions to these problems. I also discuss how to continue growing my professional skills and bring my teaching philosophy to life in my teaching practices.
