I teach in senior high school in the Philippines, we do use LED TV's, we regulately allow the use of smart phones, tablet and laptops in the class to facilitate learning.
The main problem in our case is the reliability of internet connection, the cost, and still many students are in the low income bracket that they do not have these tech gadgets.
We are almost on the door, of the future classroom, but we just can't fit. You know what I mean.
Yeah, that's true. Third world countries often have those problems you mentioned. Maybe in the nearest future, there will be solutions to such problems.
Steemit can be used in the classroom, as we use blogspot and wordpress, definitely steemit can do right?
