One possible version:

Parents meeting is a way of communication between the school, teachers and students’ parents. It means to improve the study of the students. But different students have different opinions about it.

Some are against it. They think it is of no help to their study. And if their parents know their low marks, they will scold them. But others don’t care about it.

In my opinion, parents meeting is of great value, because parents can know more about their children; besides, they can also follow the teachers’ instructions better.

So I’m for the idea and my parents take great delight to take part in it. And usually we talk a lot about it.
