Discipline: It´s a form to work in the classroom

In our days, to work with children, teens and teenegers isn´t easy, because this person don´t have will to study or they came back to school to play. In my expierence with teens and adults, I saw many diferences , mainly when I work with adults. I can see the difference between this class, because the adults present will in start learning a new strange language, while the teen don´t have will to learn a new language. They simply to come to school to bother the other classmate or your own english teacher.
According Sulich Magdalen(2004), "discipline is understood today to meaning conforming to rules , to suprevisors orders , and to demands of the community or an institution . Even its derivation is separably connected with education. "
I agree with actor, because in many schools doesn´t have discipline. There are only disorder beside the classroom, teenegers doesn´t have respect with the teachers and with your classmates, and with this nobody learn nothing, the teacher doesn´t arrive to explain the lesson or until to many students this class finished being a"lose the time to learn ".
But what we can to do to resolve this problem?
Firstly, is very important that the teacher must apply the rules to everyone without favouritism.Rules must be concise and clear, and every students must receive a copy or the teacher should ask to your students write some rules in a big paper and put on the wall, before in every class, to think why is important to do this rules.
In English Forum Teaching (pg.11),Magdalena apresents to us three methods to maintain discipline:1) Keeping students attention ( provide a clear structure for the lesson- after greetings the students begin by briefly stating an outline of the lesson);2) Do many short activites instead of a few long ones(short exercicies that change the task and work required of the students can help focus their concentration); 3) Use an un predictable or when calling on student( criate strict rules togheter at the begining of the course , even in the first lesson).
Second Oss, Débora "The motivation is a point essentialy important to process teaching learning.If the teacher doesn´t motivate to teach your student, certantly the students, aren´t motivate to listen the teacher and with this, the desorder finishes take place the class.
According to lectures, indiscipline same beign a problem in our practice diary, many authors put us many solutions that we can resolve this problem, but it´s very important to know how use this.
