I use the task base method and I think it is the best method to understand the content 100%. When I teach a subject, I allow the student to become an expert in that subject with many exercises in different and varied forms and sometimes with games and two-person and group interactions.
I always used music along with the lyrics along with the course book, which is very important and effective for the correct pronunciation of words and keeping the student's interest.
I worked as a teacher in language centers for five years and as a private tutor for more than three years. I worked with more than a thousand students and I have a lot of experience in this regard.
