Authenticity

Authenticity is a tough and broad topic to cover in being a teacher.  Being authentic with your students can be very trick and has a fine line that a teacher doesn't want to cross.  I feel that there are certain times that you should be authentic with your students and tell them the entire truth on a matter, then there are certain times that things should be left out and discussed later when the child is older.
A student should have the feeling that their teacher will explain a topic if there is good reason to explain it.  Otherwise the topic is not appropriate and should not be discussed.  However, if the student feels that their teacher is unnecessarily hiding things from him or her than the teacher needs to be a little more Authentic with their students.  Also teachers can't' make up what they feel or believe, so falsifying a opinion or idea would an example of not being authentic with your students.
Teachers should be willing to share their own personal opinions when the time and place calls for it.  Otherwise, personal opinions can be left out of the classroom and education can continue.
