Katherine, It is fixable if you will think about what the real problem is in relation to class management. Is it because of your age or is because of how you have set up the class. Once you know where the student challenges are coming from you can move to fix them. Do you have a routine so the students know what to do when they come into class and get settled? Are you clear in your expectations? Are you showing your student respect so they can in turn respect you? Are you being the learning leader in the class? Once these questions are answered you can then develop a plan where you can take and retain control of the class and the bumps should smooth out. Gary Gary Meers, Ed.D.
