Fair and equal treatment 

Everyone should feel welcome and comfortable in order to enhance their learning experience. 

learning the students why will help you guide them. 

Getting to know them helps to understand their priorities and you are able to assist and mentor them through their educational journey. 

Games and other ways of learning are often good for remembering information as it gives them something to relate to. Changing things up can also help with attention span. 

Learning about your students can help drive the way you teach content. 

I think a combination of things comes to mind. Getting to know your student's learning style as well as limitations areas they excel in. Looking at the class from their perspective and also integrating real life scenarios to help bring the subject to life.
