Josh Lerman, the senior editor at Parenting magazine, explained on The Early Show it could be that, for whatever reason, the child and the teacher just don't blend.
"Either a squirmy kid and strict teacher or a shy child and a loud and strict teacher," he said. "There are a number of different ways teachers and kids can rub against each other the wrong way."
The other issue is some kind of incompetence and, in that case, it's not you (or your child) alone. In this case, he suggests talking to other parents to figure out what the problem is.
"Your child can't tell if a teacher is competent. You're the only one that can make that judgment," he said. And since it is unlikely that a 6-year-old could tell if the teacher is not qualified, the personality clash is probably the issue parents will have to help their child deal with.
Here is what Lerman says parents can do to help their children:
Get your facts straight
"Your child is unlikely to come home and say, 'I'm a little upset because my teacher is quite strict and that upsets me,' " he said. "Chances are your child will say, 'I have a sore throat, I can't go to school.' Then you have to ask a series of questions, 'What's wrong?' It turns out that 'The teacher was mean to me.' You have to figure out what's going on.
"Was the teacher mean or saying, 'You have to do better next time on the test.' It's not because your child is a liar. It's because they're little people and things get twisted inside their head."
If you are still not certain of how your child is being treated, he suggests talking with other parents of kids in the class. "Ask them, 'Has your child said anything about Mrs. Grumpky?' "
Don't be confrontational
"Start out assuming you and the teacher are a team working together for your child's education," he said. "If you start out confrontational, the teacher will be defensive and you won't make progress.
"If you're furious, it wouldn't hurt to have someone else in the meeting to calm you down. But if both parents go it implies a more serious issue, so if you are just fact-finding it's OK if only one parent meets with the teacher.
"You want to give the teacher a way to let it go to the next level without them feeling like you're going over their head. So you might say, 'What can we do about this?' Or "It sounds like we're still seeing things differently, so what do you suggest we do next?' That way it's not like you're going to the principal. And if the teacher isn't responsive, then you can go over her head. You can tell a lot by what she says. If she's defensive and confrontational through the entire meeting, then you're not getting the information you need and you have to take it to the next level."
Enlist the school's help
"The school has seen a lot," Lerman said. "They've seen a lot of whiny parents and whiny kids and a lot of kids that act up. If you go in there as a whiny parent, they're not going to take you seriously. If you go in there as someone concerned about your child's education, who wants to work with the teacher to make everything turn out right, they're going to take you seriously, and be straightforward, and see what they can do to help."
