The adaptation of a child to school is a really important thing in his life, so teachers have the duty that this experiencie is possitive for them.
I consider that teaching is a hard work because it's not only a job, Before being a teacher of any subject, you must be a teacher of life ,in general, sometimes acting as a doctor, as a father paying attention all their needs. Most of teachers don't realise until it's too late.
I have been very fortunate with my teachers as in primary as in secundary school since most of them have been confident, professional and could speak with them really well. If I didn't understand any thing, they had the ability to explain me the same thing from different points of views.
It's very important for the teacher that he really knows their students to keep a balance among them to be friendly at the same time not be too strict.
For this reason, I recommend you that during the first days at school you aren't extremely friendly until you don't know your students well.
My favourite teacher was funny and had a great personality being very close to us when had a problem.
Although I'm still begining as a teacher, I hope to be as him a future to trace in this important way as for them as for me.
