Also from your comment, I feel that I definitely fail to communicate what the actual problem is.
The problem is NOT that the kids (and their teachers) cannot access certain sites. Although they might not be able to afford it, if they want.
The problem is that they DON'T KNOW that internet sites exist. For a kid who was born into the era where a magical handheld thing can show his friends' life and funny videos, a "website" means nothing. I even didn't want to write handheld television screen, because most of them haven't even seen a television before.
They don't know that wikipedia exists at all.
Another anecdote (maybe I should summarize it in a post somewhere) is that the teachers were using Oxford Press's Headway [1] books. Excellent series, many of us in Europe learned English from these books. It improves your vocabulary a lot, teaches you words like "coin", "train conductor", "mp3 player" and so on.
Now let's see what does NOT exist in Laos, at all: - mp3 players - TRAINS!!! - and, well, coins (Lao Kips start at 1.000 bills (10¢) IIRC and last time coins were issued was 40years ago. In the 2mo I stayed there, never saw a coin, nor the kids I was teaching).
It's really a different world, it took me some time to even start my head wrap around it
