Nah, this is all #JustMyneThing
Normal orphans don't learn this fast, her children books/toys/'reward program' enabled them to study at much easier/faster pace.
On the translation: Some lines were probably credit to the wrong speaker but otherwise it's at least readable.
Yeah, she made education fun, and entertaining, even more in a World in which they lack a TV, radio or even newspapers, Myne managed to give them education and a card game at the same time, a win-win situation.
I mean, think about nowadays education, most people don't wish to know about how someone who died 200 years ago will impact their lives, they wish for practical teaching on life, but its not like schools teach the students about how to fill a CV(curriculum vitae), or how to do fill a taxes form.
One interesting way that got me to get interested in learning Math while I was struggling with it, I wasn't paying attention to class one day and my teacher had a normal conversation with me and on my hobbies (it was nice of him instead of scolding me), so I started talking about a game I liked called Dead Frontier and started explaining to him its economy system, i briefly mentioned how once I had troubles to calculate a 9mm ammo box based on a full box price and that I had to make guesses on it, he then took a piece of paper and teached me Cross Multiplication, using the bullets quantity, the value of a full box, and the value of a box with a certain amount and how much the final value would be based on the price per bullet. At such moment, the whole concept of cross-multiplication seemed so easy and entertaining to learn.
Long story short, he explained to me by using an easy term that I had interest on and and it made me interested in learning, thinking about how at such time there was something that I would actually use in practical life. And indeed I have used it.
TL|DR, it isn't about what you teach, but how you teach, a teacher job isn't just teaching, but about how to get the student engaged and wishing to learn, and how little bit of empathy can go a long way if you try to see through another person perspective instead of scolding them.
