I am teaching physics for JEE competition exam which is one of the most difficult exam in the world.
As a teacher i can readily convey the concepts, delivers them in a simple and approachable way so that students can easily understands.
I use real life examples in my teaching method. Depending on students i use various teaching methods also which contains interesting examples, diagrams and even video clips. If a student faces some difficulty in particular topic i try to give more concepts, equations and theory about it and try my best to help them in doing imaginations about the same. I increase the level of problems than previous one to build a strong base for the students with much stronger concepts.
If someone wants to understand the nature and its laws in their true aspects then here is the subject he or she will love. According to me the best way to understand this subject is to imagine the things and while teaching i always take care of it, i want my students to imagine the problems and come up with a better solutions. i use a lot of real time examples in my teaching method, i always try my best to deliver even the tough concepts in simpler way, for example in rigid body rotation we can demonstrate if we roll down a solid and hollow cylinder, which will come first and why.
i always try my best to deliver each and every concept in a simpler way so that my students understand it in a better way and gains more interest in the subject.
