Making your teacher's voice heard is a simple way to transform behavior without costly training plans or resources. Simple changes can have a profound impact on the way you communicate with your students. It's the easiest way to achieve a happier classroom environment. The point of that long story is that even the softest teachers WILL NEED to raise their voices sometimes, and that's fine.
Part of being a good teacher is having that much-needed skill, even if you don't want to use it. He has served as Charleston County Teacher of the Year, Walmart Teacher of the Year, and CEA runner-up as National Educator of the Year. It must be a frustrating year for you to have to raise your voice so often that it can go a long way in alerting the teacher to how her actions are perceived both inside and outside the classroom. But if it's true and your child's teacher routinely raises his voice, it may be something he wants to mention to the teacher.
It's also a bad idea for a teacher to raise her voice to a particular student when everyone else is sitting quietly. If a teacher cries out of frustration or anger, then that teacher needs to reflect on the effectiveness of this tactic. If you feel guilty about raising your voice when children are pushing each other (especially at a time when they are supposed to keep their distance), you may not be cut out to be a teacher.
