It wa particularly convenient for viewing pond water--I could lug the scope around without worrying about an AC outlet.<br /><br />"Waste" is a strong, but the appropriate word. I remember hating that part of science when I was in school, and I bet it still turns off millions of kids.<br /><br />It's not how science works, no more than writing works by laying out file cards. <br /><br />There are better ways....doylehttps://www.blogger.com/profile/12901661320505882735noreply@blogger.comtag:blogger.com,1999:blog-4956989639073843954.post-64667479956017587432013-07-19T11:51:07.164-04:002013-07-19T11:51:07.164-04:00In 1960 when I was 10, our family came into posses...In 1960 when I was 10, our family came into possession of a family heirloom, a beautiful, old brass microscope that was housed in a solid wooden carrying case. The 5 of us kids didn't hesitate to drag it out and use it (it only had a mirror as a light source so lighting was always an issue) to look into the world of the small. Of the many, many wonderful things I observed, the stem of a plant covered with aphids and a few ants that were herding them was the one that still loops endlessly in my memory. <br /><br />School will be starting up soon and I know that a disconcerting percentage of my biology teachers (earth/space and astronomy for me, thank you) will waste a couple of weeks on the 6 (or 9 or 5) steps of the "scientific method", a couple of weeks foundering around in the metric system and a couple of weeks with microscopes. <br /><br />Sigh...copehttps://www.blogger.com/profile/06470278603925838339noreply@blogger.comtag:blogger.com,1999:blog-4956989639073843954.post-41930921812785261922013-07-18T16:55:41.186-04:002013-07-18T16:55:41.186-04:00Dear Lindsay,

I agree with the need to grasp scale--which is more difficult each passing year.<br /><br />Once the kids know something that small does pretty much the same things that they do, understanding scale makes a little bit more sense.<br /><br />When anyone figures out what grades mean, chirp in--they're about as meaningful as the new teacher eval systems bandied about these days.doylehttps://www.blogger.com/profile/12901661320505882735noreply@blogger.comtag:blogger.com,1999:blog-4956989639073843954.post-84064580744570070282013-07-18T11:45:31.566-04:002013-07-18T11:45:31.566-04:00One of my biggest, most gratifying teaching moment...One of my biggest, most gratifying teaching moments this past year is a self-declared "I'm bad at science" student coming in to my classroom every free moment she had (including lunch) to use our new microscopes to look at pond water.<br /><br />She got so totally lost looking at the same water that she was disgusted by most of the year. <br /><br />We say we're shooting for mastery (unreasonable at this age in my opinion) and that's about as close to mastery as I've seen. She became so adept at sampling the water and finding the most interesting protists. And I had no real way of measuring it, you know? No points were given to her--this was not an assessment, grades were already in for the year.<br /><br />But I was so much more impressed with her patience and how she spent hours (literally) observing a drop of water than I was compared to a student who aced my exams only because she wanted a perfect GPA.<br /><br />I hope she believed me when I told her that the skill and concentration and curiosity she showed is rare and wonderful and will serve her well.<br /><br />But, I must admit that I think it might be worthwhile for students to understand a little about the microscope--the number of lenses used, how it magnifies, what the total magnification is just for the sake of understanding scale.<br /><br />Regardless, I keep going back to this wonderful student and what grades really mean.<br />Susan Eckerthttps://www.blogger.com/profile/09159073219086902316noreply@blogger.comtag:blogger.com,1999:blog-4956989639073843954.post-1703459901067338772013-07-18T11:32:15.307-04:002013-07-18T11:32:15.307-04:00This is exactly the point I was trying to make wit...This is exactly the point I was trying to make with my colleagues this year. It's about the genuine interest in Science, not the nit-picky details of labelling parts, etc. Thanks!Lindsayhttps://www.blogger.com/profile/14004998305334786620noreply@blogger.com
