To anyone wanting to broaden their horizons by teaching English abroad and looking to enhance their abilities to teach in TESOL environments, or those looking to supplement their existing teaching experience with a TESOL certification, or even those hoping to start building their experience as a teacher to begin working in the field of education, I can wholeheartedly recommend the course at TEFL International Tokyo. I had a great experience here and think that is largely due to the knowledgeable, engaging, and supportive instructors who taught the course, which is to say, I truly believe that the experience you gain by doing this course at TEFL International Tokyo is experience that cannot be obtained anywhere else.
The curriculum does a great job of preparing you to teach English. Topics covered include history of foreign language instruction techniques, principles of language teaching, teacher language, phonology, and English grammar. I found the grammar sections to be taught in a way that was remarkably engaging and relatively painless, so don't let the fact that grammar is one of the subjects covered in the course intimidate you, the instructors do a great job not only of presenting the content but stressing the points that will help you be better able to teach your future students about these topics.
You will also begin working with students in your first week of the course, which I believe is one of the benefits of taking the course in person. You will be able to put the skills you learn during class to use immediately in a practical setting, which serves as good reinforcement for the material and also lets you evaluate your own performance as a teacher.
I think this course is great for anybody who would like to teach English anywhere in the world, not just Japan; though the course is taught in Tokyo and the material is often introduced from the standpoint of how best to work with Japanese learners of English, the course covers topics in such a way that you will be able to apply the teaching principles covered in a broad range of contexts, countries and cultures around the world. With that said, Dave, Larry, and the other instructors on the course have decades of experience between them teaching in English in Japan, so if you are interested in teaching in Japan yourself after taking the course, you will have a world-class team of teaching professionals ready to offer you advice and guidance about how to break into this vibrant industry and help you in taking the next steps to find employment in Japan.
Lastly, if you have the opportunity, staying at the TEFL Residence for the duration of the course is a great experience, as you'll not only get to know your classmates and instructors better and have a very quick walk to get to class, but you'll also get to experience urban living in a fantastic neighborhood of Tokyo. You'll have access to nearby amenities like grocery stores, restaurants, and a jaw-dropping athletic center, and the huge Mizumoto park is also nearby, which is a real treat for a morning run (or just an afternoon stroll).
All in all, I highly recommend this course for those looking to obtain a TESOL certification, and especially those looking to get a taste of Japanese culture in the process!
