I try hard to remember I'm not a parent. Believe me, as a teacher, it's easy to sit in judgement on them, especially when you feel like you're doing a great job with a kid who, for whatever reason, doesn't connect so well with the folks at home. But I should recollect that I spend about 45 minutes a day with most of the kids I see, and that then I go on about my merry way, sometimes not thinking of them again (sorry, guys) until they're back in front of me for 1st period. Besides, I think that most (not all) parents are doing the best they can with the limited tools they have.
Still. I do wish I could get parents to see one thing that teachers can see as clear as day: when a kid needs special services. Every teacher I know has stories that they could tell, of a child who needs glasses; a kid who lisps; a student who needs counseling. Yet the parent declines to provide these or even allow the school to provide them. We have so many students who could be successful if they had just a little extra help, and the parent refuses. They don't want the child to be made fun of; as though sitting in the classroom, failing because you can't see the board, is a sure path to popularity.
This isn't a cultural or an economic issue, either. The worst example I saw of this was when I taught preschool in a wealthy part of New York. We had a child in our two-year-old classroom with an extreme sensory disorder. She literally put everything in her mouth: sticks, poop, other kids hands, etc. We approached the parents, who were wealthy and intelligent, about getting her help and they flatly refused. We approached again after the child ate an entire cup of sand, and they told our administrators that they would pull the child from the school, as we were harrassing them. We were told to let it go. One of us spent all of our time monitoring that child, and the other teachers made keeping the other children away from her part of our routine. It was awful.
I often think about the girl, who'd be in her tween years now. Did she ever get the help she needed? I pray she did. She wasn't "just rambunctious." She needed help.
I don't a parent's perspective on this question, but I do have a disabled person's perspective. I was in speech therapy when I went to elementary school, since I couldn't hear myself form (or not form) some sounds. I don't remember much about it, but it was fine. I needed it, so my parents sent me. I don't recall being teased about it (although maybe I just didn't hear it, ha ha!). I went again in college, for the same reason. Again, it was fine. My speech therapist was a sweetheart and she let me play the games she had for little kids; I recollect a video game with a penguin that jumped when I said "zzzz" into the microphone that was pretty awesome.
When people need help, they should get the help they need. I wish parents would see that, even when it's difficult. The services in public school are usually free. By the time the kids get to me, at 17 or 18 years old, it's too late. Get kids the help they need.
