This just gives a small insight into ALL of the things teachers are expected to do in front of around 37 students on a daily basis. Not to mention the fact that the teacher needs to display enthusiasm for the content, establish a safe and efficient classroom environment, and build genuine relationships with students while also managing their behavior. Before criticizing a teacher, really try to put yourself in his or her shoes. It's an amazing job that I love, but it sure isn't an easy one.
