Changing Teachers...why?

Some of my students have complaint about why I decided to change my classes this term. This is, I believe, what EVERY class needs in order to grow by an acceptable pace. Here, I will try to explain why I believe this.

1. A great FRIEND, but an old TEACHER! Sometimes I feel I and my methods and strategies are getting old and boring. I simply LOVE each and everyone of my students but loving is not enough. In fact, students do not come to an English class merely to make friends. They are there to LEARN. So, it is learning which, under any circumstance, comes first. I think I should never forget the primary goal of my students and although I love to be their teacher FOREVER, I have the responsibility to do what is right, not what I love.
2.  New methods, new windows! Every teacher has his/her own ways of teaching. And they all have advantages and disadvantages. So it is advisable, from time to rime, to experience new methods and reconsider the best ways of learning. This is what I call "Evolution" in learning. ِA new teacher is like a new window. Students might or might not like the view. But all in all, it is useful to have different perspectives when learning something new.
   
3. Keeping in touch! There are many ways for students and teachers to keep in touch. Although we always need a safe and entertaining place for friendly meetings and it may be a part of the learning process to help students and teachers stay in touch and continue their friendship while learning new things. I believe participating a class is not the best way to keep in touch. Students pay money and spend their precious time to attend classes and we, the teachers, are responsible to help them learn. 
4. SHOCK! After several terms of having class with a teacher, sometimes students fail to maintain an English-speaking class, as they should do. Or, they get used to methods or rules that little by little are taken for granted by the teacher. The teacher, too, cannot force his/her students to stop the false methodology due to being TOO close to them. This is when, I believe, the class needs a SHOCK. Normally a new teacher can start everything all over again and establish the basis of new correct methods and trends.

 At the end, I would like to say that I truly, deeply and honestly love my students and more than anybody else, it is me who is missing the lovely classes and the memorable moments I shared with them. I pray for their growth and success and I hope they will forgive me if I, by no intention at all, caused any of them to panic.
