Treena is a bright and personable girl in your sixth-grade class. A large part of your classroom activities involve class participation through questioning and recitation. Treena, however, never raises her hand and, when called on, "freezes" and often says nothing. You notice that she is social with friends. Her shyness seems restricted to speaking before a group. Discussion with her fifth-grade teacher indicates that the same behavior took place last year. What are two possible strategies to help Treena succeed in your class?

Explanation:

The first strategy would be to know the reason why Treena is so afraid to speak in public. In psychology there’s the term called glossophobia which is “the fear of speaking in public”. This is a common fear amongst people. People that suffer from this fear don’t like to feel the pressure of it, being put in the spotlight, and don’t want to feel rejected from the things she or he might say. To overcome this problem the person needs to gain confidence within itself. Public speaking is just a matter of trusting yourself and knowing that you have the capability of overcoming this problem. Some helpful tips would be to breath smoothly, because by breathing, you will calm down. You would need to organize your ideas and slowly speak with confidence. You need to realize that people will not reject you if you say something wrong, you need to embrace your error and learn from it. And most importantly is that you need to understand that there is nothing to fear and that you are surrounded by people you can trust, and that could have the same problem as you.
