Breaking out of the classroom into the world....
I love this post!
Ironically two high school science teachers I had in the 60's also enlightened us with their slide rules. We respected them for their dedication and zeal in their infallible calculations.
LOL I learned to use a slide rule in high school and memorized multiplication tables until I could do large-number math in my head. Obviously dating myself.When I taught density, speed, distance, momentum, etc. last year, I was continually frustrated by most students complete inability to do math. In fact, I learned that you should never do speed experiments across a 2 meter distance (a convenient size in a classroom) because they are completely incapable of putting 2 in the numerator.Don't get me started about their inability to double-check their calculator math. It is apparently possible to drive 600 miles to Chicago in 1.2 hours at 50 miles/hour.
I just wrote a blog post athttp://pencilintegration.blogspot.com/2010/01/lamenting-loss-of-nouns.htmland it struck me how much your thinking and writing has influenced me. If it sounds too much like plagiarism, it's only because your blog has made a difference.
Dear John,We simply share ideals--no worries. I read your book, I get ideas hours later, hard to tell what comes from where. You write from the heart, and you pay attention. I hope I do the same.Dear Paul,Slide rules are so cool because they're so exposed. I don't remember my HS teacher loving the slipstick as much as I did. My joy approached fetishism.Dear Kathryn,I wrestle with the same thing, and need to keep reminding myself that it is our generation, not their generation, that created the problem.I spend some time in class playing with numbers. Just today, a child worked his way through what to us would be a very simple problem. I suspect a few kids are starting to realize they're missing something,
