can a teacher afford to be wrong?- views needed (urgent)

Teachers are also humans and I do think that they get it wrong many times. I hate teachers who try to cover up their mistakes or beat around the bush or act smart just to show their kids that they know it all when they actually dont. I do respect teachers however who admit their mistakes in front of their kids and admit they dont know something when they really dont. Teachers should create a learning environment where it is not just the student who is learning but the teacher as well . i think students will respect their teachers more if they try to be involved in the information gathering and decision making process rather then directing and telling the kids what to do.

Hi! Yes, teachers are also humans, but I think they must not make mistakes. I am a teacher in German, and I am not suppose to make any mistakes, because I don't feel good when I make some. And also as I say, teachers must know more than their students, or what for they call theirselves teachers? Teacher means you must learn the others(not only kids), and that's why you must know more than they know and also you must not make any mistakes. Just imagine- "a student ask me about the translation of a word in German. I don't know it and tell it to him. What will he thinks of? What is this teacher, who doesn't know German? Why is he teaching me then?" I think, I am right, am I not?
