Questions about SBI and classroom management

In this term, teaching is becoming a bit difficult. Some questions may emerge as how I can set up and mantain order when teaching. Well, we should know that classroon management has a variety of factors we must tale into account; moreover, we, as future teachers, should be aware of the energy we are going to create in our classroom through some aspects.
I like to present myself question before teaching, "how would I like to find the classroom if I were the student?" This question helps to take care of the aspect of the classroom before teaching because the enviroment in which the students are, indeed, affect their learning process. 

The neatness, cleaning, and the order of the classroom play an important role in our classes. Similarly, the seating arrengment, interferences, acoustics, and weather can disturb students´ attention in the class. As a personal opinion, the school I´m teaching at has movable desks, that is a big advantage for me beacause I know the other teachers DO NOT make use of the desks and they don´t move them. So, I try to provide my students a different class by rearranging the desks in different positions. 
There are other things we have to take care of such as the white board use and the equipment use. Talking about the board, it has to be clean since the very beginning of the class. You can paste some charts, draw some graphs, give your own examples, and provide your students visual aids for them to better understand the topic. But, DON´T FORGET THE BOARD WHEN YOU FINISH YOUR CLASS. Now, I understand why some tacher get mad when entering a classroom and finding the board all dirty.

Another thing we have to be aware of, when trying to mantian the order, is our tune of voice and our body language. We have to know that when teaching, we must speak as natural as possible because our voice is going to give us the confidence to teach and we´re going to sound secure about the things we are talking about. Our nonverbal expressions are very important due to they are caught by students easily.
One thing I can tell you is that many topics can arise at very moment of teaching and you have to know what to do. If the topic in question has to do with the topic your students are dicussing, try to relate it in a very smooth way. Don´t cut your students´participation; let them talk about the topic if they´re speaking in English, obviously.

An external question may be born someday, "how can I learn successfully a new language?"
Our answer must be STRATEGIC INVESTMENT; nevertheless, many of you may be wondering what that means. Well, let me tell you that strategic investment means that the learning process has to be match with investment. We all have to be clear that "every set of complex skills is acquired through a combination of observing, focusing, practicing, monitoring, correcting, and redirecting."
