Schools have systems for students to learn. Maybe some teachers have to change the way they teach so a schools system can work. A teacher's role in class is to always find ways to keep students learning. Maybe one day they will go outside and read or listen to a tape. A teacher has to find various ways to be able to capture the students.
Administrators have to make sure the teacher is doing a good job.
The parents have to make sure the students do their homework and get to school on time. My purpose of education, is that students understand my lectures and learn to problem solve. Trying to make class fun and interesting to students. So that they are able to understand the subject. As a teacher you have set rules, maybe a list of rules on a wall.
