Adult materials, Mark? What
do you do in the classroom???
Seriously, I'm teaching adults constantly and write all the materials for the school. I rely on the Internet mainly for articles to give me ideas for texts, which I then rewrite at the appropriate level, and for pictures - thank goodness for clipart and flickr - then build activities round those. I don't use much ready made stuff as everything I do is tailor made very specifically to the needs of the students - but I know that if I was teaching general purpose English again I would.
But outside lesson prep I'd be equally lost in the rest of life without it. I can go days without TV, never turn the radio on hate the telephone and rarely listen to music - but go to the internet for everything from correcting homework (via E-mail) to reading the news to this evening's dinner recipe. The only thing I would less like to give up are books. What about you?
