I had read the teacher's intro., so wasn't too surprised. Teacher didn't mention age group, but I'm guessing early teens. This probably is of no interest to many of that age group, but the better students did make an effort to comply. There are always some disruptive ones in any class, and I don't envy teachers that have to deal with it. Who knows, some of these kids may end up as regulars on the site at some point. In reference to the post mentioned here...there are lots of people that don't know the difference between a tree and a grass....and Lord knows they won't pick up a book. Sadly, this is the world we live in now.
