I doubt that.
Tell the parents they have to take it up with the administrators first and then only get the teachers involved if it is warranted. Easy solution.
The teacher should always be the first step for a parent. I had a number of great principals who would not hesitate at shutting down a parent who had not talked to me. Why? It was usually a kid's understanding of a comment not even meant for them.
Want an example? I was called out of class to meet with a parent that showed up without notice to complain that I called his son stupid.
I was teaching how to solve multistep algebraic equations on the day he was absent. I told them to ask themselves what is being done to the variable and reverse the order of operations to simplify them.
For example, given 3x + 12 = 24, solve for x. I told them that since 12 is being added to the variable, to subtract it from both sides of the equation. 3X + 12 - 12 = 24 -12, leaving you with 3x =12. Then asking yourself what is being done to the variable, it is multiplied by three, you would divide both side of the equation by 3, giving you 3x /3 = 12/3, when simplified gives you x = 4.
I related the story of one student I had at the DoD dependents school who was so frustrated by these problems, I would ask her the questions, step by step and she would easily find the answer. She became so frustrated by this, she referred to the problems, saying, "I hate those stupid questions". From that point on, every student referred to them as the "stupid questions" to solve it.
The next day as we were going over the homework, I referred to the "stupid questions" as we solved the equations. The kid assumed I was calling him stupid, since he had been absent and didn't know the background story.
I related that to the father, who asked his son if he had asked about the "stupid questions" which, of course" he had not. Dad was livid with the son, and my principal had set at his deck, smiling away! I can imagine the young man learned a valuable lesson. He was a good kid and a great student, both before and after this incident.
You want to waste hundreds of thousands of dollars because kids jump to conclusions? I have numerous examples of this, such as calling a kid "retarded" when those words would never cross my lips. That is an interesting one to address cameras because I was not in my classroom, but a computer lab that could not be configured to use cameras.
