The classroom should be warm and inviting, and should be a home to each of the children that are a part of it. Many times a classroom belongs to a teacher, in an ideal classroom it would belong to the teacher as well as each student. I believe teaching is an art, not a science. Science is something that can be proven and tested, and usually works the same way each time. Art on the other hand is creative, and requires freethinking, much like creating a successful classroom and successful learners.
Teaching requires time and flexibility, and the willingness to accept changes.
There are no set theorems or rules for dealing with kids. I believe the student determines the direction of personal growth. There is only so much a teacher can do, and even an excellent teacher cannot force a child to experience personal growth. A teacher can give a child every opportunity to experience personal growth, but it is up to the student to decide if they are going to allow personal growth. A teacher can only do so much, and then it is up to the student to decide if they are going to take the opportunities and experience growth.
