I feel that good classroom management is a skill that teachers acquire over time.  I don't feel that it takes one specific way of managing the classroom to have control, but actually quite a few different techniques that a teacher molds into his/her own unique style.  One of the most important factors related to good classroom management is a solid understanding of classroom management theory as well as an understanding of your students personal and psychological needs.  This helps the teacher to understand why problems exist in the classroom and between themselves and the students.  When a teacher has this understanding he/she can use what they already know about the problem to try and solve it; if that doesn't work, he/she can then turn to a colleague who might have learned another method of solving a particular problem to help out.  Another factor I believe you need for good classroom management is establishing positive teacher student and peer relationships that create classrooms as communities of support.  This helps students feel that teachers are really here to help them meet their own basic personal and psychological needs.  The final factor I believe you need for good classroom management involves using instructional methods that facilitate clear classroom organization and optimal learning by responding to the academic needs of the individual student and the classroom as a whole.  This I feel will help the low motivation, negative self-attitudes, and failing students by giving them structure, organization, and the support that they need in their lives.  Fairness and structure combined with clear expectations and a clear lesson in a caring non-threatening environment, I feel are the key elements to maintaining good classroom management.
