text: Most schools are turning to you do everything on computers. Some schools make it where you have to purchase a computer and you take it home. They don't have to buy textbooks, everything is just on the computer. When you miss a day because of snow you aren't actually missing a day. You do the lesson for that day on Elearn at home and you don't have to make up that snow day. Even at home you can get feedback from students because they do their lessons on their computers. You can learn a lot from facial expressions and Facial Action Coding System is a good way for teachers to learn what students like and what they don't, even from home.
