Another little story ...
Years ago--as computers were beginning to appear in classrooms (though not yet in mine)--I used to have the kids write pen-or-pencil drafts of pieces in class. I spread dictionaries around the room so that they could save me some grading time later on.
And, sometimes (especially in the Proficiency Test years), I would give them practice tests--writing for 30 minutes or so on a surprise prompt. (Dictionaries still available.)
Example: You type pancke; it supplies pancake, peacenik, panache, punk, etc.
Anyway, I saw no reason not to let him. And the writing began.
A few minutes later, his hand was in the air. I went over to him. He showed me a screen that listed a half-dozen options or so.
"Yes?" I asked.
He pointed to the screen. "Which one do I want?" he asked.
And so I got another lesson: Dictionaries and spell-checkers help only people who are decent spellers to begin with.
When I first saw the AlphaSmarts, I thought they must have been invented by someone who was OmegaDumb. But I got used to them--found ways to use them. I was surprised to see on Google that they're still available ...
