I expect most of their value is in the ads on the side of the phone booth.

Comment keyboard problems? (Score 1) 55
Anyone know if they fixed the keyboard on this one? The one I got last year still can't accept touch typing: you must type slowly. So rapidly typing "asdf" will generate "assdf" or sometimes "asdsf". Pretty unusable unfortunately.
Ask Slashdot: Teaching Chemistry To Home-Schooled Kids? 701
First time accepted submitter mikewilsonuk writes "I have a 10-year-old grandson who has shown an interest in chemistry. He is home educated and doesn't read as well as schooled kids of his age. He hasn't had much science education and no chemistry at all. None of his parents or grandparents have chemistry education beyond the school minimum and none feel confident about teaching it. My own memories of chemistry teaching in school are of disappointment, a shocking waste of everyone's time and extreme boredom. I think there must be a better way. Can anyone suggest an approach that won't ruin a child's interest?"
Comment Check the statistics not the mathematics! (Score 1) 404
This is really a question of statistics not of mathematics. Having done experiments on MBA students, we found that a well written multiple choice question is more accurate than 4 well written essays. The fact that we can easilly have 50 multiple choice questions and a maximum of 8 essays makes it a no brainer that multiple choice is much more accurate.
So it isn't a matter of how you reward guessing (which psychologist will say that rewarding guessing actually gets better accuracy). It is a question of how well written the questions are. Further the pass rate has absolutely nothing to do with the fraction needed to pass. Even high school students understand this one. So he seems totally confused.
