I use a homogeneous method to teach a subject or any other topics. By which a person who is trying to learn will not feel bored or difficulties in it. For example If I was trying to teach about synonyms then very first I'll tell about the background and definition of it with current usage. Once a person start taking interest in a particular subject or topic then things become easy to teach someone. So this a very basic fundamental idea for me which work a lot (as per my opinion). It work in most of the conditions (including every countries and every classroom).
