When my daughter was in senior kindergartern here in Canada she had a great teacher who emailed us everyday. Just a one liner of what the kids did that day - coloring, sang a song, whatever. It was fantastic. I know some of the kids were recent immigrants and I'm going to assume some of the families were poor, but the email list seemed to have all the families names on it. Having your name on the list was optional.
So it can be done, and I don't think it needs much infrastructure or effort for a simple system.
Now, the next year, when my daughter changed schools and teachers I mentioned this to the new teacher at the first parent-teacher meeting. She said: 'I've heard about that teacher. I won't promise anything.' She implied that she would take it up with the union as to whether it was a requirement of her job.
I am now getting more and more familiar with the educational bureacracy, but there are good teachers out there, and simple, appropriate solutions that help.
