How can understanding demographics help us better understand teaching and learning ?

The reason I feel that it's important to understand demographics in order to become good teacher is because classrooms will always be diverse. Whether the classroom is diverse with race, age, gender, or personal views, the classroom will always be diverse. Teachers need to be able to conform and mold their lessons around these demographics this way their students will be able to understand what is being taught. For example, if students have different political views and you are teaching a history class certain subjects/topics might cause the class to disagree with each other or the information being taught. The teacher much present the information in her lesson in a way that will not create issues of discussion. I also think that its important for teachers to understand demographics because if they do it opens up the communication even further between the teacher and student.
Throughout my whole school experience I always felt that the outcome of the classes and the subjects I like the most every year was based on the teacher I had. The classes I tended to like more my teachers were always open and supportive of their students and clearly were there to help their students learn, not just to teach the subject. In my perspective and my experience I feel that teachers who were only there to teach didn't really have much effect on their students. On the other hand the ones who were there for the soul purpose of teaching helped their students inquire about the subjects being taught and had more of an effect on them. These teachers who had this positive effect on me and my classmate clearly understood the importance of demographics. The importance of demographics is clear. In order to be a successful teacher you need to know and understand the demographics in your classroom and be able to create a learning environment that will benefit the students you teach.
