Teaching is a skill. You need to express what you have to your students. It is not easy to do that. One of the biggest issues is about our audience. For example, if you talk more logically and mention all the relationship between each other like a detector to your primary school students, it is impossible for them to know what you are talking about. It tells you always consider your students so that you can use the accepted language for them. It is a good way to use their language and thinking to teach them.
