Teaching and learning activities can be influenced by the environment. If the environment is clean, it can increase the concentration of the brain work so that the concentration of thinking wider. Vice versa, if the environment is dirty then it can decrease the concentration of the brain work so the concentration of thinking will decrease, because the concentration of the brain can not be separated from the environment.
