Dr. Jeff on Mathematics Education


This is a Dr. Jeff’s Jeffism and a Dr. Jeff Speaks Out.



Math is the language of nature. If you yearn to know

how she operates, you must speak her language.

—Dr. Jeff


I wrote this essay because I needed to get something off my chest. It first appeared as a foreword to a Dr. Jeff’s Weekly Challenge posted on June 15, 2009, but I think it’s so important that I decided to commit it to a formal Resource Page here at Blog on the Universe. My Resource Pages are all found in the right navigation column under the section titled “Pages” and under the subsection titled “Dr. Jeff on Stuff – The BotU Resource Pages” (take a look at right.) I dedicate the Resource Pages to essays on important topics like: the Nature of Our Existence, the Art of Teaching, Scientists and Engineers as Heros and Role Models, and the Crisis in Science and Technology Education. I felt that an important essay on mathematics and mathematics education should be a dedicated Resource Page.


So here now is my sure to be viewed as an outrageous essay:

This is a Teachable Moment in the News and a Dr. Jeff Speaks Out.


This is crossposted at the Huffington Post HERE.

I had a day of meetings yesterday, with no connection to the outside world. When I got home a good friend stopped over and asked if I heard what Al Gore had said in Copenhagen, and the firestorm it created in the world media. I had not. So I made a beeline for the computer and sought out the circus-sphere passing for journalism these days. Here is what I found.


A Timesonline story titled “Inconvenient truth for Al Gore as his north pole sums don’t add up”, may have been the focal point. Apparently Mr. Gore said, as reported by the Timesonline—

MESSENGER Spacecraft Named by Time Magazine as One of 2009’s 50 Best Inventions, and Other Cool Mission Highlights & Updates

Photo Caption: Image taken September 29, 2009 by MESSENGER’s Narrow Angle Camera (NAC). The distance across the bottom of the image is 250 miles (410 km), which means the crater at lower left is about 80 miles (130 km) across! The crater’s appearance points to Mercury’s volcanic past—to a time when the crater was filled with lava and now only portions of the crater’s circular rim are visible. (Click on image for zoom.)


This post is a Teachable Moment in the News.

Remember the MESSENGER spacecraft we were all following back in September as it flew by Mercury? The little spacecraft that gave us all a scare during the September 29 flyby (hey little fella, don’t do that again) is day-by-day getting closer to orbital insertion on March 18, 2011. We’re now just 15 months away!


I promised to keep you all posted with new mission updates. My last was October 17, and there have been a bunch of things piling up to report. I could have just quietly inserted the new updates on the MESSENGER Mission Updates page here at the Blog, and snuck in a date change in the Teachable Moments in the News QuickLinks Box in the upper right corner above (your cue to look in upper right corner). But hey! When Time Magazine names a family member as one of the 50 Best Inventions of 2009 (and by the way, we were number 11) YOU’VE JUST GOT TO CELEBRATE WITH AN OFFICIAL POST!
