Nepali teachers, I have observed, do not use humor much or often. I am not sure why.
This blog contains embeds of two short clips from a presentation to students at a school in Kathmandu in which I use humor.
Nepali teachers do NOT use humor as much as they should. I do. And so in my workshops for them, I use it to demonstrate its effectiveness. Follow link for short videos of me in action -- telling jokes and making teachers and students laugh, to grab their attention and hold it.
Another example of how and what a teacher uses as a teaching tool or resource is really limited only by the teacher's imagination! This is about a lesson I helped a science teacher conduct using what they had.
