One of the many consequences of low science literacy and high level of religiosity and the attendant belief in superstitions in the highly patriarchal Brahmanic society of Nepal is unabashed cruelty to females. One way the cruelty is meted out is in the way they are blamed for a newborn's sex as it that were determined by gestation and birthing. Science says otherwise, of course!
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.
