I have been tutoring Japanese for five years. I have four students right now. For the beginner students, I usually use the textbook and follow the textbook. But, I will change the method if the student has some other ideas to learn. For the advanced students, I talk with the student and correct the grammar or the student bring the books or the textbooks to read. The student asks the questions about Kanji and the meaning of the whole sentence and I answer the questions.
