At these days classroom management is a big problem for teachers. The problem grows day by day in every school. As we know by the improvement in technology and science affected every side of our life. Everything including our culture,tradition, way of looking at life changed so much. Now, there is huge gap between generations .Most things which older generations are familiar with seem strange to new generations.So we can immediately realize that high culture is no more sensible to teenagers who are already being slaves of popular culture. In that culture students create their own world in which they feel comfortable, relaxed, and free. They form rules according to their wishes and logics. They carry this popular culture into every part of life like working place , school . home and etc  in which informal attitudes arent allowed or are regarded rude.
   Especially in the schools unwillingness of students is a big problem. we have to focus on so many crucial things to be able to solve this . firstly the teacher should be well educated in her field and have vocational formation as well as general knowledge. To be able to make their students motivated and effected ,the teacher should have these qualities. they should make a positive classroom environment . while forming that environment ,it is expected to set the rules both teacher and students together . Because students adopt the rules which they determined themselves. The teacher should be prepared before lessons . It is useful for him looking for different sources as  well. Because when you cant answer their questions,you make students believe that you dont know the subject thorougly. so they can lose sense of security of your lesson . After awhile even you can use your authority . One of the way of protecting your authority is to be well educated as well.
    It is crucial to be able to draw attention of students to lesson. So at the beginnig of the class , teacher should explain the goal of the lesson, why the information they will learn is needed , in which field they can use them and etc. When students know ojective of lesson , they will be more willing to participate lesson and learn things.Moreover, it is mostly observed point that this generation doesnt want to accept the thingd which are told them directly as done in the past . In contrast to that they want to learn reason of it. So you can confront with many students who will ask a questions related t its goal.Ayrica this generations changes quickly. Wen yo go home and come to school following day , it is possible for you to see one o your student*s  attitude has already changed without giving any sense . By the way it is possible that it is possible that their attitude against you can change as well. At this point teacher shouldnt get into deeper personalities of students . Because it can cause you to lose authority or you can put a block between you and your students comunication as you emerge their personalities. For those reasons , it is always good to know only general personalities of students and only to use them to solve the problems relating to them.
   It is also wrong to start a lesson immediately. Before that he must introduce the lesson in a interesting way, by asking questions or mentioning an event in daily life
  you should encourage your students t involve in discussion. For example you can ecourage themby asking questions . But never allow them to convert this conversation into an arguing. In argue they can say negative things to eachother and this can discourage them to participate the lessons. Any spark in argue can make (especially for this generation) your students monsters in one or two minutes. And results of this can be big problem and to mention the worst one it can be  irrecoverable.
   Healthy comunication is indespensable element. when you take communication as a way in which you transfer your thoughts to students, then you should use the way very effectively. Because the things that you told is only as much as you are understood  by th one who listens to you
   Also it isnt easy for a teacher t always continue in an effectiv way in the lesson. So he should say the things by refining them . When the students dont understand the lesson , this also maks them tired
   Every students should be observed carefully. It is important for teacher to be aware of presence of students. That is to say he should know whether any students learned , made progress  or not . If you dont , it is possil for you to have a students who will say i didnt understood anything at he end of the year
   you should make them believe that you dont have prejudice against them . Some of your students can think that you use you authrity to take revenge from them as they arent obedient to rules f lesson . So you can ensure them by giving trust that you are the person who isnt prejudios but trustable guide.
