I have already taught Physics to students in a school. I have experience with different kind of students so I know how to handle students differently. I always teach concepts with the help of stories. As Physics is the study of laws of nature we can actually connect to daily household activities while studying Physics that's what I do I relate the concepts to the things which students know and which is trivial so it makes easy for them to understand concepts. Also, give assignments regularly which helps students to develop interest in subject. Physics is the subject most relatable to our day to day lives what we observe happening in nature. What I think is Physics is already very interesting subject one just have to build interest of students to it in the beginning. I hope you will find it very interesting while studying with me and you will also become a physics lover.
