Atychiphobia or Gelotophobia?

It is always a question between these two in the classroom. The first, fear of failure and the second, fear of being made fun of. It is always a battle of these two phobias when it comes to answering questions. This week, I saw probably 15 students put their hands up with confidence, only to say "never mind" because they second guessed themselves or were afraid their answer was wrong and didn't want people in the classroom to laugh at them (not that anyone would have). With all of the standardized testing, we have created an environment in the classroom to where students are scared to say the wrong answer because we put such an emphasis on being correct and having a high score. 

I guess it might just be the age that the students are that discourage them from answering questions but it is still a problem. My CE has never been mean to a child who answered a question wrong and would send anyone who was mean out of the room. I think students just don't want to be humiliated if they answer a question wrong, and why should they be? If you are never wrong you can never learn, because if you are never wrong you already know everything. We have bred fear into the students and it keeps learning from taking place. We are supposed to teach the students and answer their questions but it is socially unacceptable for students to ask questions because it makes them look "dumb." 

Sorry for the rant, but it all seriousness, this is a serious problem. As a future teacher of my own classroom, I have to ask myself what will I do to fix this problem? I could have a question box for students to ask me any questions they have in private but that only partially eliminates the problem. Sometimes, students need questions answered right then in order to understand the rest of the lesson or concept. I am just wondering what I can to so that students know that it is okay for them to ask any question that relates to the content. Has anyone else come across this problem with their students or is it just middle schoolers?

Also, I had a quite humorous exchange with a student this week. A boy, who I go to church with, asked if he could call me by my first name. My response was obviously no but he persisted. I explained to him that I was going to be the teacher and that he didn't call my CE by her first name. He still said he was going to call me by my first name when I hear "I have something that might change your mind." My CE had an office referral in her hand and was smiling at him. He laughed it off and said "I will still do it." She then told him she could start filling it out if she needed to and he shut up real quickly. I am worried that I may have to deal with this problem later in the year and will just have to cross that bridge when I come to it.
