Remember all the teachers you have had in your life? Were they all meaningful to you? As I am was growing up, I have had some good teachers, some average teachers, and some horrible teachers. Before I came to the USA, I had was full of expectations about new friends and teachers. However, I soon realized that teachers in America are about the same as Korean teachers. Since I’ve been studying here, I’ve noticed that there are three types of teachers. This is what I found out. The first type of teacher is a passionate teacher who you will always want to have. Usually, these teachers are professional. They have a passion for their subject and their students. They always prepare for their classes before the classes start and usually their lessons are very interesting. When students have a problem with something, they really encourage students and listen to them. Every student feels free to talk with them, not just for conferences. The second type of the teacher is normal teachers. They are usually not so professional or caring. They usually had have just enough passion for their subjects and their students. Usually, this teacher doesn’t remember their student’s' names, and when students go to this teacher to ask some question, they would rather tell them go to ask either their friends or seek help from other teachers. The last type of the teacher is a horrible teacher. They are boring, lazy and unprofessional. They don’t seem to have a passion for their subjects and their students. Usually, these teachers like to tell stories during the class instead of teaching from prepared lessons. They don’t even care about their students and doesn’t don't show any interest in them. Students normally don’t want to go ask them and questions during conferences or talk to them about any problems because, student already know they don’t care. Everybody will have these types of teachers in their lives at least once. Teacher affects people so appreciably that they even have power to change their student’s life but mostly we don’t get to choose teachers we want. However, it is the same condition that teachers can’t choose their students, neither. Personally, I believe whether you are a student or a teacher, you should always try to be the best person you can be.
