Welcome to Sachiko's Electronic Portfolio!

My name is Sachiko Aoki. I am an English teacher with five years of international teaching experience in both English as a foreign language (EFL) and English as a second language (ESL). I am very passionate about language teaching as well as language learning. I earned a Master of Arts Degree in Teaching English to Speakers of Other Languages (TESOL) at Teachers College, Columbia University. I am very interested in theories and practices in Second Language Acquisition (SLA).


I taught English in Japan for more than six years. Fortunately, I had opportunities to teach both children and adults ranging from 2 years old to eighty years old, from beginning to advanced levels. I have always enjoyed teaching and learning from my students. I treasure every student and every moment I shared with my students. I have also had opportunity to teach  ESL courses in the United States. It was such a great experience for me to teach diverse classes in New York City, a melting pot. Currently, I am teaching EFL at the college level in Japan.


I am also teaching Japanese as a Teaching Associate at the Department of East Asian Languages and Cultures, Columbia University. It is very interesting to see language teaching from the perspective of a native speaker, which I believe is helping me to teach English more effectively.

As a learner, I have always found it fascinating to communicate with people in foreign languages. Communication with people from all over the world certainly enabled me to broaden my horizon. In 2003, I attended ESL classes at Washington State University. There, I met two inspiring teachers. One of them grew up in Russia. She amazed me with how clearly she could explain English, despite being a non-native speaker. Her instruction helped me reach new level of comprehension because she showed me how learning another language in fact means learning entirely new culture. The other teacher inspired me to be courageous. She said to me, “Don’t be afraid of making mistakes” and “You don’t have to be perfect.” She taught me how important it is to learn from mistakes in language learning. She was also humorous, which helped me relax. I really wanted to be like them. I wanted to inspire others the way they inspired me.

Ultimately, as a language teacher, I hope to learn and provide effective methods in order not to leave any learner behind.
