Capturing the Teaching Moment: Predicting Election Results – part 2

I was recently watching a pre-election podcast of the CBS McLaughlin Group show (clip below) in which John McLaughlin asked Pat Buchanan to predict the outcome of the presidential election.
He said: "The outlook is [a] probable Obama victory." I paused the podcast at that point and thought that what Pat said was not exactly a hard call to make given the multimedia rendition of data that I just watched. I wondered at that point what he would have said if he was also asked to predict the margin of victory in percentage points. (I found out the answer later in the show but I didn’t know that at this point.) Here’s a summary of the show's pollsters' predictions. The point spread ranges from a low of 3 to a high of 15. I've added an additional pollster "pundit" which I affectionately call "Kid" Average and include this numerical wonder as a candidate for the best estimate prize as well. A question for you. If we could turn back clock to before the election results were known, which polster would you have bet on to have made the best projection (i.e. came closest to the final outcome based on the polls provided by McLaughlin?) I would have bet my money on "Kid" Average who as I found out later did reasonably well. (See spreadsheet below.) According to today's (11/10/08) CNN website Obama won by 6.6 percentage points. I used a simple average of the polls to come up with my prediction. The pollsters not only use averages but also more sophisticated regression methods to make their projections. Here's what is written in the FAQ page at pollsters.com: "In most cases, the numbers are not an "average" but rather regression based trendlines. The specific methodology depends on the number of polls available.
• If we have at least 8 public polls, we fit a trend line to the dots represented by each poll using a "Loess" iterative locally weighted least squares regression.
• If we have between 4 and 7 polls, we fit a linear regression trend line (a straight line) to best fit the points.
• If we have 3 polls or fewer, we calculate a simple average of the available surveys.
So it's possible for students to see real applications of these techniques as they learn about statistical methods. Plenty of math here for students to sink their teeth into where the technology is integral to the discussion. Oh, yes. What prediction did Pat make in term of points? Check it out in this next clip. It sounds like John and some of the others could use a math tuneup or two. If you are one of those "i can't get enough of this" folks, the drama of the election is still playing out in some corners especially the race for the Senate in Minnesota. Currently Norm Coleman leads Al Franken by 206 votes! See http://www.fivethirtyeight.com/2008/11/more-minnesota-madness.html for the latest details.

Capturing the Teaching Moment: Predicting Election Results – part 1

What I would do on Monday (11/3/08): As you all know today is the day before Americans elect the next president of the United States. If I was a teacher in a classroom today, I would assign the following homework:
Students: I would like you to make a prediction about who will win the presidency and by how many percentage points. Write up your rationale for your prediction. On Wednesday, we’ll analyze your data and see who came up with the "best" prediction.
I suppose one “easy” way that a student may do this would be to go to a website like this one and see what the pundits are predicting. From the current (3:15pm 11/3/08) graph it is clear that Obama is the favorite to win. The 311 electoral votes predicted would top the required 270 votes necessary. So predicting Obama’s victory appears to be a safe bet. But what about the point spread? If you click on the map above you will go the website where the actual map is. If you hover the mouse over the map you get a state by state prediction of the point spread. But where do these numbers come from? If you notice there is a link on the left side and just below the map (above) that answers the question. Since I don’t have a class to work with today, I’m hoping that you might be willing to play along with me and send in your prediction with a rationale for the number of points you chose. (I’m using Google Docs Spreadsheet for this activity.) Go to questionnaire and post your entries. There is only a small window on the entry form so you might want to write out your response elsewhere and then copy and paste in the form. I’ll be back on Wednesday with an analysis and an explanation of how this exercise can illuminate important math ideas.

NCTM Elections 2008

Dear friends of CLIME, If you are a member of NCTM you probably received your ballot for the upcoming NCTM elections (deadline: October 31st). Having been an NCTM member for most of my adult life (and with some forethought could have had a life time membership for \$150 in 1967) I want to urge you to vote this year. I have not always paid close attention to these elections in the past mostly because I didn't know the people running for office and from their resumes there didn't seem to be much of difference among them so it didn't seem to matter so much. But that was before I realized how important the board members are in deciding policy for NCTM. Case in point. Most recently I was disappointed by the Board's decision to not invest in the future by looking at the cost of technology as too expensive and not worth the investment at annual meetings. Renting busses is also very expensive, but the board sees the urgency of paying the outrageous fees for busses, but not for the technological infrastructure necessary to help math educators take advantage of the what technology has to offer us as the collaborative and participatory nature of Web 2.0 continues to grow and be a dominant player in the real world, but not in our math classrooms. There are no panaceas in the technology promise, but the train is leaving us at the station as our math leaders at NCTM are still looking at technology as an expensive frill and not an integral part of what's needed in the math classroom. It already is a part of our students lives, so we need to help make it a part of our teacher's lives in the math classroom.  What I'm doing as an NCTM member is casting my vote for someone who in my opinion is a champion of viewing math education creatively through a technological lens. Ed Dickey was my chair person on the program committee for the 1999 San Francisco Annual meeting and had the foresight then to see that there needed to be a technology liason on the committee as we approached the new millenium with all its technological promise. I was fortunate enough to serve in that role and admired his effort to push the agenda towards a more innovative and creative future for mathematics education. Ed has also been good friend of CLIME over the years and always encouraged me and others to continue our efforts in support of the vision of how technology can serve the needs of the math educator community. So I encourage you to join me in voting for Ed Dickey as a new At-Large NCTM Board member of NCTM.  (For more details click here). Best wishes, -Ihor Ihor Charischak CLIME president Council for Technology in Math Education ihor@clime.org http://clime.org

Technology updates at NCTM: some signs of life?

Though the NCTM Board was adamant about not spending \$\$\$ for wireless access in Washington, DC (see previous blog) there are signs of technological life at NCTM. Here are some examples:
• Call for Manuscripts: 2010 Focus Issue: Learning and Teaching Mathematics through Technology. It sounds like the NCTM Editorial Board is interested in catching up with what's happening with technology in math by soliciting manuscripts for their Mathematics Teacher journal. Unfortunately, by the time these papers get published in 2010 most of the articles will need an update. This Web 1.0 strategy may need to be reimagined*.
• Check Out NCTM's Math News Feed. Now you can keep up with what the media is saying about math education. Read the Council's scrolling news feed online, or subscribe to the RSS feed to have it delivered to your computer each day. Source: Member Update Newsletter
• At the affiliate leadership meeting in Philly last month Hank Kepner (NCTM's new prez) encouraged members of CLIME and others to share ideas about how best to incorporate Web 2.0 (and other tech as tool) ideas in the teaching and learning math. I'll be sharing these ideas in future CLIME blogs. In the meantime please share your ideas with me. (Click on the envelop icon below.
* Dictionary.com tells me there is no such word as reimagined. Does that mean it belongs to the Web 2.0 lexicon? (I think so.)

Board's response to the technology resolution is in... and it ain't pretty.

Photo: Affiliate Conference - Philly
The NCTM board has replied and as expected it ain't pretty. See Board Acts on 2008 Delegate Assembly Resolution.

Preview: Affiliate Leaders Conference in Philly, August 15-17

Next weekend is the NCTM Affiliate group leaders conference and I'm planning to attend. I hope to find out more about the Board's decision concerning the resolution adopted in Salt Lake City and get a sneak peak at what's in the future for NCTM and technology. II’ll update you as soon as I find out. As you may know Jim Rubillo NCTM’s executive director is planning to retire a year from now. Skip Fennell is heading up a search committee for a new executive director. Hopefully, the new person will be able to champion technology more as we continue our journey through the 21st century. BTW - NCTM sent me a copy of "Our Iceberg is Melting: Changing and Succeeding under Any Conditions" by John Kotter to read in advance of the conference. It's a fable about penguins surviving on an iceberg. Could major change be in the air? Let me know if there is anything you want me to find out from the head honchos at NCTM.

Board's action on Technology concerns at NCTM meetings to be acted on soon.

I checked in with Mary Ferris at NCTM to get an update on when we will hear what the board decides to do about the resolution that was passed at the Delegate Assembly at the NCTM in Salt Lake City in April. She replied: The NCTM Board of Director’s meeting is July 24-26. Affiliate leaders and Delegate Assembly participants will be notified through the AffiliateNews electronic newsletter when responses have been posted. Passed resolutions and the Board’s actions will be printed in the NCTM News Bulletin this fall. I'll let you know the outcome as soon as I find out.

In Search of a Beautiful Mind - Seymour Papert

From this morning's Boston Globe:
He was long a jewel of the MIT faculty. Now, after a devastating brain injury, mathematician Seymour Papert is struggling bravely to learn again how to think like, speak like, be like the man of genius he was. Read the article.
In Search of a Beautiful Mind
Seymour Papert inspired the origin of CLIME back in 1988 and his courage continues to inspire me now.

The Wanna Do Curriculum - Math & Web 2.0 continued

In my last entry (on the old iWeb blog site* CLIME blog) I started to write about a math curriculum that students actually "want to do" (instead of the current "have to do" force-fed one) where context and content are mixed together in a way that engages students to want to learn. This what I call Math Ed 2.0 where math and technology merge to create a beautiful friendship. I'll be sharing more about what I mean in my upcoming CLIME episodes. Stay tuned...

*Dotmac switched to mobile me this week and has caused much havoc with iWeb publishing. So I will be using Blogger's site for my CLIME blog from now on. CLIME's home page will continue to be at clime.org hopefully without too many glitches and will have a link to the current blog. No one ever said that the Web 2.0 world was going to be easy to navigate... but then these are the pioneer days. Welcome aboard!

Latest Update

Trying to recover from iWeb RSS temper tantrums.... Is this way my salvation? Stay tuned.....

A letter to Skip Fennell

On Technology in Math Education (2.0)
Open Invitation to the CLIME community
March 31, 2008

Last year just as the Salt Lake City (SLC) program committee was about to meet, I wrote an email to Skip Fennell regarding my concerns about technology at the annual meetings. Here it is.

Hi Skip.
My affiliate group CLIME celebrated their 20th anniversary at their annual meeting during the NCTM meeting in Atlanta in 2007. It’s hard to believe that it has been more than 20 years since Papert and Logo made such an impact on our collective consciousness making us aware of the possibilities that technology can have in math education. 2007 was also the first year in more than a decade that there were no computer lab sessions at the annual meeting. Many of my CLIME friends were concerned about the message this sends to the NCTM community, namely, that computer workshops are no longer important or needed.
Since my participation on the program committee as the technology liason (SF, 1999) the labs have always been for me an indication that NCTM takes technology very seriously especially after technology was declared one of the essential principles the 2000 Principles & Standards. Unfortunately, NCTM’s technology principle starts to fade in its impact when the vendors take over demonstrating the power of technology. In Atlanta Texas Instruments once again was a dominant player in the vendor area and textbook companies continued to roll out technology into their packages in a formulaic way.

After some reflection, I realized that discontinuing the labs in their pre-Atlanta form may not be a bad idea after all.  Maybe it’s time to focus on a more relevant way of using computers in today’s (and tomorrow’s) classrooms so that their use reflects current and emerging technologies. The computer lab model is slowly giving way to a newer vision of how computers are used in schools. Laptops and handhelds in an wireless environment are slowly making their way into classrooms. The emergence of portable technology with the possibility of every student having their own laptop will have a tremendous impact on the teaching and learning of math in the coming years.

CLIME’s dream has always been to have a “strand” of sessions at the annual meeting that demonstrates and lives up to the vision of the technology principle. The labs were our best hope for that in the past. But now with more universal wireless access to the Internet, laptops, handhelds and Web 2.0 sessions at NCTM can embrace the vision of the technology principle in a more unique and compelling manner.

My CLIME group suggested that it would great if we could get a conversation going with the program committee about how the technology principle can be promoted now that the labs are gone. Is this a possibility? What other issues are there that the group might not have considered?
Thanks – Ihor

Skip responded positively to this email and shared my message with the SLC program committee However nothing of substance materialized. So now I’m looking forward to the 2009 meeting as a possibility to make an impact.

I need your help in putting the Technology Principle back on the map highlighting some of the Web 2.0 features that can be used in the teaching of math. I’m heartened by the work of TPCK and want to see more discussion of how it impacts future curriculums.

A final thought:
The technology principle needs an internal organization that will continue to remind the NCTM board that the hope for the future is how well we take advantage of the current and emerging technologies. I realize that you may not be going to SLC or you will have other priorities especially
If your schedule is anything like mine. I’m supposed to be at the Affiliate Group Caucus at the same time I’m leading the session at NCSM. So I’m planning to solve the problem by cloning myself.

I’m interested in any thoughts you may have on this matter and what we can do collectively to have an impact in Washington. So on April 9th I will be introducing a new initiative for  CLIME 2008-2009 which will hopefully culminate in an useful expression of our ideas.  We need our collective voices to be heard.
