Stormy Weather

Typhoon Paka on December 15 at approximately 0...Image via WikipediaI've been following the news of the hurricane traveling up the eastern seaboard.  Hurricane Irene's intensity seems to have peaked long ago and it is starting to deteriorate into what we call around here a "banana bender".  It sounds like a wet storm so I suppose flooding is the worst concern.
Living on Guam for the past 22 years has exposed me to over 15 major typhoons- as they're called in this part of the world.  I've been through three Super Typhoons: Yuri, Paka, and Pongsonga.  A super typhoon has maximum sustained winds of 150mph or greater, comparable to a category 5 hurricane. 
It's been almost 10 years since we had our last typhoon.  I don't know how long our luck will last but we'll be ready for it.  Guam is situated in a convergence region so it has seen many typhoons in its history.  Most of our structures are built out of concrete because anything less gets torn apart.  Guam doesn't have many tall trees for the same reason.  But with the extended lull in activity the island's vegetation has had a long holiday.  I'm sure the next typhoon that comes along will cause a big mess in this regard.
The first lesson I made for Real World Math was the Typhoon Project.  Using Google Earth as a typhoon tracker was an obvious choice when I first saw it.  I saw it as an interactive map of a weather event.  I'm sure I wasn't the first person to use a mapping graphic in that way, but it seemed original to me back in 2007.  Now I see similar graphics for Hurricane Irene in all of the news' sites I've been reading.  The National Weather Service has a kmz generator which, as I understand it, can create radar overlays for Google Earth.  I haven't tried it yet so let me know what you think.

Great tip for editing placemarks

Thank you Aaron Slutsky for this gem.  This is a quick and easy way to format images, videos, and text for your Google Earth placemarks.  Can't wait to see how it handles text and color formatting.

Professor Morris Kline revisited

A mathematics lecture, apparently about linear...Image via WikipediaAs I was researching material to form the ideology of Real World Math, I tried to find sources that would support the best methods of math instruction. There exists a great number of studies that present the failures of math education, but a disproportionate amount that provide the answers.  One only needs to visit their library to find that the section on mathematics takes up the least shelf space.  And so it happened that I was in a university library that I found a publication of Professor Morris Kline's Why Johnny Can't Add, literally gathering dust.  Although it was written several decades earlier, I had found an influential voice in my view on mathematics.

Kline was professor of mathematics at NYU, and from the 1950's-70's he was a rebellious voice in higher education.  He expressed strong beliefs that the math curricula was misguided and ineffectual, taking particular aim at the New Math of his time.  What I found so striking about his words was that his criticisms seemed just as relevant today as they did half a century ago. There are many of his views I could share with you but for this post I will select one.

Professor Kline believed that perhaps the greatest failing in math education occurred when it was divorced from the physical sciences.  The date of this event may be hard to determine, but it probably occurred when a publisher created a textbook entitled Algebra and another Chemistry.  He observed that many of the great mathematical minds of history were individuals who studied science; Descartes, Newton, and Gauss, to name a few.  Throughout history, mathematics was the means in which scientific observations and deductions were made, but somewhere along the way formal education separated them into distinct subjects of study.  Mathematics became a separate field of inquiry.

Kline felt that the failure of math education was not the fault of the student but of the material they were learning.  Without science, or a connection to the physical world, math had lost its purpose.  Learning mathematics for the "beauty of math" or the goal of learning more purposeless material would not benefit the majority of students.


What should we teach? We want material that will provide motivation, sustain the interest of the student, exhibit the methods of the operation peculiar to mathematics, and demonstrate the chief values of mathematics. I believe that the answer is to tie mathematics closely to the study of the physical world. I do not mean that mathematics should be buried in some corner of a physical science course but rather that we should motivate interpret, and apply mathematics through fundamental physical problems and of course include wherever possible the broader implications, largely cultural, of what mathematics has accomplished. Mathematics derives from the study of nature and is valuable mainly because of what it returns to nature. - Kline 1955

If you are familiar with my site, then you can see how I took Professor Kline's words to heart.  I have tried make connections from math to the physical world so that students can see how concepts are applied.  Many of RWM's activities are suggested as cross-curricular content for science; perhaps there should be more.  What I would suggest to you is that you find a way to reunite the disciplines this year in some way.  Talk to your fellow teachers and try to make correlations in your instruction.  Show the students how ideas and knowledge are related so that they can realize their learning has purpose.

New school year...

Back to SchoolImage via WikipediaHope your summer was restful and you are ready to start a new school year.  Although I haven't posted any new lessons for a while, it doesn't mean that I haven't kept myself busy.  I've had a number of projects I've been working on in the past months but I'm eager to add some fresh content to the site.  I'll insert my usual plea for lesson suggestions here.  Please email if you have something you'd like to see on the site (4realworldmath@gmail.com).

Truth be told, I have a large PBL activity that I'm currently working on; I'm still researching and collecting resources.  Once I get over the hump of obstacles, the work will go much more quickly.  I have a few ideas for Primary age lessons and I'd like to get to Mars this year.  I'd like to add a Problem of the Day feature; I've been collecting material for that throughout the summer.  So try out the lessons that are available and keep an eye out for new content coming this year.  Announcements are also made via Twitter (http://twitter.com/RealWorldMath).

If you are just getting your feet wet with Real World Math lessons or if you have a new group of students that will be using Google Earth for the first time, then I will direct you to a previous post: Back to School.  You'll find some tips and suggestions on which RWM lessons to use to start out the year.

Finally, I've created an About.me contact page (http://about.me/RealWorldMath).  This should make it easy for you to recommend RealWorldMath to other teachers - so why don't you?

Moby and Me

As I mentioned in a previous post, one of the best things about ISTE conferences is you get a chance to meet face to face with the people whom you've only had a cyber connection with.  I'd be remiss if I didn't mention the individual that I was most anxious to meet - Moby.  Yes, that's right; Moby from BrainPop was the first person I sought out when I got to the convention hall.  My two girls are big fans and so I wanted to make sure I got a photo op and few trinkets.  BrainPop seems to keep growing and growing.  Every time I view the site it seems to have more content and it continues to win award for excellence.  BrainPop's explains concepts in a very concise manner with animations designed for children ages 3 and up,  If you have students in grades K-8, then you will want to take a look at what the site has to offer for educators.  See you next year, Moby.

ISTE 2011: Looking back


It's taken awhile, but I'm ready to share my thoughts on this year's ISTE conference.  I've been traveling for the past 3 weeks so I have a lot of sorting out to do.  As usual, I've come away with new ideas for the upcoming year, made some great contacts, and gained a sense of validity to the work I do.

The majority of my time was spent in Boston but the train ride to Philadelphia was a highlight.  I've never seen that stretch of New England before so I enjoyed that portion of the trip.  Traveling by train was much more enjoyable than traveling by plane!  Philadelphia proved to be a great host city.  I don't think I have ever seen such a concentration of places to eat with a tremendous variety to choose from.  As expected, the conference center was huge so that gave an opportunity to work off some calories.

The conference is pretty overwhelming.  On any given day, you have hundreds of choices to follow.  I like going to the Exposition Hall and seeing all of the vendors and their products.  I like to think that I gain a better sense of what tools are out there and what the coming trends are going to be.  As far as the latter, I think you'll see interactive projector systems in place of the whiteboards, and an even greater increase in shared resource learning systems.  Safari Montage is still my dream application.  A lot of systems now have social networking as a component.  Instead of hearing how all of the States' standards are addressed in learning systems, this year the word was "Core".

I found it harder to follow the program this year.  I attended a disappointing BYOL session (in large part because of the lack of Internet connection) and I browsed some of the Poster sessions.  It's always great to see the passion that people bring with their work.  I noticed a large increase in the amount of math related content this year which is encouraging.  The second day was a bust for me.  Because of a morning keynote, the sessions didn't start until 10am.  Add to this a 3 hour stint of volunteering in the afternoon and most of my day was gone.  There's always conflicts in your schedule.  If I go next year, I would like to connect more with the special interest groups and the informal sessions that spring up throughout the day.

The Real World Math poster session went well enough.  I was prepared with my materials, but 125 pamphlets proved to be not enough.  The poster sessions were tucked away on the side of the conference hall.  This was disappointing because they didn't get the same amount of traffic as they did in Denver.  My session was on the last day around lunchtime so the attendance was lower than what I had hoped for.  I was able to share my site with many who were unaware of it.  I'll have to hope that exponential power of networks will help spread the word further.

Overall, it's hard to justify the costs of travel to events like these.  Even harder to quantify the gains you take away.  Ironically, the same technology that we are promoting enables us to connect year-round outside of conference halls.  Still there's something special about the opportunity to meet face-to-face with over ten thousand like minded people.
