> I basically destroyed my teacher's plan of early physics education. Basically, the teacher wanted to replay physics history a bit by explaining the early experiments and what people thought about them.

What did you do to destroy the teacher's plan? It doesn't sound incompatible with you having advanced knowledge.

I remember we were doing something experiments with electricity and the teacher asked some question. I just answered that it’s a stream of negatively charged particles.

The concept of electrons or charged particles wasn’t introduced yet. So this didn’t make sense to students who learned according to the teacher's plan. I think he wanted us to develop an idea of charge ourselves instead of learning from a book.

(I think this is an outdated way of teaching because students have so much other resources on the internet to learn from.)
