"Let the teachers do their jobs!"

I was flipping through channels on the radio the other day on the way to the store, and I happened to overhear Mike Gallagher talking about parents going with their kids to their first day of school. I guess some school districts are encouraging this because they are trying to encourage parental involvement with their kids education.
Mike was getting all huffy saying that parents should just butt out of their kids school lives, and "let them go through the rite of passage of going to the first day of school alone".
He had lots of people calling in to agree with him, mostly teachers. Mike had the nerve to say, "Why don't these parents just let the teachers do their jobs?!"

Since when did training our children become the job of strangers? Doesn't God plainly tell us in His Word that we are to train up our children? Does their training end at 5 years old when it's "time" to send them off to kindergarten?
I'm sorry, but just because the world says that I should give my children to someone else to train (including other Christians at a school) does not mean that I am going to. And I challenge all Christians who believe that the Word of God is good for instruction to research this subject! I believe that the Bible's instructions regarding our children cannot be carried out fully if we are not with our children for the 40 hours a week school takes away from us. How are we to mold their character if we do not have the every day chances to do so? How can you mold a child in the evening hours between homework, supper, and bedtime? Why would we give our children such a disadvantage in life as to be seperated from us?
The worldly philosophy of quality vs. quantity time is a farce. As parents, especially as mothers, we have the greatest amount of time and influence with our children. We should use it wisely. We need to step back and re-examine our culture's way of raising its children. Does sending your children away for 40 hours/week allow the time for cultivating a deep and meaningful relationship with our children? Does it allow for us to impart God's wisdom and values in a real life setting at the time that they occur? Does it allow for us to correct our children when they need it? At the moment they cop an attitude towards someone, or something that didn't go their way?
Each one of us, of course, is responsible for our own lives, and must find the answer to these questions for ourselves. But I encourage you to research this! Look on blueletterbible.org for the words children, train, teach, etc... Decide for yourself. Romans 14:5 says "Let every man be fully persuaded in his own mind."
Whose job is it to teach our children?
