In my experience of tutoring, the one thing I've observed is how a classroom setting is not always suited for a student. Everyone has a different learning pace and slow learners can feel discouraged even though they're competent and fully capable of understanding the subject. It takes time and patience which can be provided by a private tutor and that is clearly evident; as with my guidance, I made a student who despised maths be able to be able to get a decent score and also have some appreciation for the subject. Another thing about tutoring is how it can be a learning experience for the tutor themselves as well. It's just like how AI learns through reinforcement learning techniques, I apply the same to myself because different approaches work with different students. Sometimes we need to make minor adjustments and at other times just change the entire approach in accordance with the students' feedback.
Typically my lessons will be an hour long and will be quite dynamic and designed in a way to keep the leaner active and engaged. For a subject like physics, and moreover in any science, having a genuine interest in what's being taught can make a huge difference. That is when boring lengthy equations start to make sense and instead become beautiful mathematical expressions that describe or quantify a physical system or phenomenon. Making this connection also helps in developing a scientific temperament. There's an appreciation for the extraordinarily people who developed these theories throughout time as well and I believe knowing about them is very crucial to learning the subject.
