I am a teacher in an institute and I teach English as a foreign language to students in an 8_week session. At the end of each session, the students are required to give their opinion about the class and the teacher.
One of my students who attended all the classes and I corrected at least 20 writings for her has written something horrible and of course has ruined my rating by saying: "What we learn depends on the teacher. I recommend teacher X, but I absolutely and strongly reject this teacher who does not know anything about teaching (meaning me)." She has also written her name on top of the paper.
She never, ever, complained about my teaching method during the time we had class together and this sudden unfair comparison has gone on my nerve. I have taken a photo of what she has written about me and it is in my mind to email it to her and ask for her explanation.
I have signed no contract with that institute and I have received no teacher training courses. I have teaching experiences somewhere else and that was why they invited me to teach. But their unfair system of evaluation at the end of each session will definitely have effects on my payment and if it continues like this, I will no longer be able to continue teaching there.
I am REALLy thinking so deeply about what I could have done wrong. My last session assessment was 20% higher than an old teacher who is teaching there for 3 years. Another serious problem I have with this issue is the "comparison". I teach Reading and Writing and my colleague teaches Listening and Speaking. Of course, I have never met the other teacher. But, he has read this bad comment about me. Why should I lose my face in front of a colleague, because of an "unfair" judgement?
Is it good to react like this, or I should keep silent about her unfair judgement?
