According to my experience, if the teachers try to apply these principles equally to all learning contexts, it will be very beneficial for the students to provide a better future. However, when I was a student in my old school, not all of the teachers used these principles. I think because they have a lot of lessons to teach us, they just focus on what they have to teach. In those cases, I also noticed that their students were sleepy and could not concentrate on their lessons anymore. 

However, in the movie, I see teacher Moe Moe Oo uses these key principles to support her students' learning. The students seem to understand what the teacher wants to mean in her lesson. It is really good to practice this, even though we have a lack of resources in our teaching. However, this video teaches me that the crucial thing is that we have to find a way for the students to still focus and pay attention to our lessons.
