Technology related sessions in Hartford

As you may know one of my hobbies is to keep track of the number of technology sessions at the annual meetings. In Philly last April more than 35% of the sessions made mention of the technology as a major player in the gist of their talk. Scott gave me a heads up about the drop off in the regional conferences.
"...Still, for the most powerful and popular dynamic mathematics programs to be so poorly represented raises questions about our commitment to helping our students become proficient in the technology tools that allow them to construct their own mathematics and/or conduct their own independent investigations. In today's technology-infused world, we seem to be sending a message that the top math technology tools available to our students, the ones that best encourage mathematical autonomy and creativity, are not important enough to use in math class."         
-Scott Steketee (taken from previous post)
I didn't track the sessions in Dallas earlier this month but I did for the Hartford NCTM Regional conference happening this week October 24-26, 2012.  I counted 38 tech related sessions which is only 16% of the total sessions.  I like to doing a wordle (wordle.net) of the key words in the descriptions of the sessions because it gives me a perspective of what technologies are significant. (See image on left.)
Wordle of all tech related key words
Since technology covers the complete array of electronic tools it always appears the most when I do a tech key word search. TI-Nspire and the graphing calculator has the edge on competing technologies. That makes sense since graphing calculators are the least expensive, most portable pieces of electronics. As Scott noted and I now confirm very few sessions involve the use of dynamic software which allows students a more active role in creating mathematics.
Sketchpad was mentioned once and Geogebra apparently didn't make the cut. Here's a pdf listing of the tech sessions.

If you are going to Hartford please report on your experience of the conference the tech sessions you attend. We need to collectively voice our thoughts about this lack of constructionist type learning. Twitter (hashtag #nctm) is excellent way to voice your thoughts about the conference.

Here are my choices from the list of 38 that I would attend if I was there.

NCTM Regionals have too few technology related sessions

Scott Steketee





Scott Steketee who is one the chief architects of Keypress's prolific source of quality support materials for Geometer's Sketchpad has been reviewing the program offerings of the upcoming regional meetings and has raised some concerns that I would like to share with the CLIME & NCTM communities.

Scott writes:
The Dallas NCTM Regional seems to have relatively few technology sessions. For instance, of the 231 sessions, there are only eight that explicitly support leading dynamic mathematics software such as Sketchpad, TinkerPlots, Fathom, Cabri, Core Math Tools, GeoGebra, and the like. Hartford is even worse; I can find only two sessions that support any of these tools. (I don't take much solace in the fact that both Hartford sessions use Sketchpad.) I have not yet looked through the Chicago program; I hope it is better. Both the Dallas and Hartford conferences also include sessions that refer to using graphing calculators and/or Web apps, and I recognize that it's not always clear from a session description what technology might be involved in the presentation. Still, for the most powerful and popular dynamic mathematics programs to be so poorly represented raises questions about our commitment to helping our students become proficient in the technology tools that allow them to construct their own mathematics and/or conduct their own independent investigations. In today's technology-infused world, we seem to be sending a message that the top math technology tools available to our students, the ones that best encourage mathematical autonomy and creativity, are not important enough to use in math class.          -Scott Steketee
 This is disappointing to hear. After what I thought was a very technology oriented conference in Philadelphia I just assumend that things would continue in a positive direction. I'm attending and co-speaking at the Chicago regional and will certainly have a lot more to say about it then. In the meantime I plan to follow what teachers are  saying about the regionals on Twitter (NCTM) and will report back to you.

If you are speaking on a technology topic at the regionals please let me know and I'll list it here. Also, take advantage of Twitter to promote your session. Just post your information @NCTM in Twitter.

Noon day project - September, 2012

Twice a year I give a shout out to all that can hear about my favorite collaborative project called the Noonday Project which twice a year has students from around the world recreate measuring the circumference of the earth similar to what Eratosthenes did 2200 years ago. The measurements are done at the time of the Equinoxes approximately March 21 and September 21. (That's because the sun is directly overhead at the equator at those times.) Since I was in Aruba on vacation in August, I thought I would "partner" with my location in Aruba and determine the "north-south" distance between there and my house in White Plains, NY. Here's my data. I know that on August 19th the sun in Aruba when it reached its zenith point in the day, cast no shadow. That means that the sun was directly overhead or another way to put is that the solar altitude was 90º. Last March I measured the shadow to be 40.2º here in White Plains.
The sun angle is formed by the sun's rays and the stick. Getting the shadow length just right is a fuzzy business because not only is the shadow "fuzzy" but it's constantly changing. Getting it when it is at its longest is the goal. That's when the sun is highest in the sky (reaches its zenith.) So with the data I have so far I want to determine the distance between Aruba and White Plains not as the crow flies, but rather when the sun is highest in the sky in both places i.e. north-south distance. Because the earth turns from west to east the sun will be highest in sky first in Aruba, then in White Plains. To find out the north-south distance we will need to find the measurement of the central angle.  (see figure below.)
The central angle equals the difference 
between the sun angles at city 1 and city 2.
The north-south distance is the distance of the arc between city 1 and city 2. (1º of arc is approximately 111 km since the circumference of the earth is approximately 40,000 km and there are 360º in a full circle.) So 28º is 3,108 km which is the north-south distance from my hotel in Aruba and my home in White Plains.
The central angle is the difference between the sun angles in Palm Beach, Aruba and White Plains, NY (City 2.) Why? See this description.


Not too late to join the project. Sign up your class here.

I Voted for Steve Leinwand for President-Elect. But Will he Deliver?

Steve Leinwand
In my last blog entry I highlighted Stanford professor Jeremy Bailenson and his keynote speech for the upcoming  NCTM regional conference in Hartford entitled  “The Virtual Revolution in Teaching and Learning.” I said, if ever mathematics education is to get out of this era of doldrums where the Common Core (business as usual) Standards is the major rallying cry, it will be lead by linchpins like Jeremy Baileson who are creating disruptive forces that will eventuallly change the face of math education. Which brings me to my curious endorsement of Steve Leinwand for President-Elect of NCTM. Steve's track record certainly makes him highly qualified. His talks are inspiring and he pushes for the teaching and learning of math to dramatically improve at every turn. He's laid out his arguments extremely well in his latest book “Sensible Mathematics Second Edition: A Guide for School Leaders in the Era of Common Core State Standards.”  But looking at the larger picture what he is arguing for may not be so sensible and reasonable after all.

In the description of Jeremy Bailenson’s talk in Hartford he writes that "virtual reality will transform curricula, assessment tools, and the very nature of student/teacher relationships." Steve argues as most endorsers of the new Common Core Standards do, that the Standards, if achieved, will go a long way to help improve the quality math teaching and learning. That's true, but what are the chances of that happening? Based on recent recent history, I would venture to say "Little to none." Why? Because it requires all teachers to become in a way super teachers. And that implies that things will only truly get better when Super-man and woman arrive on the scene. Though that would be lovely, most likely it would only happen in the movies. The grammar (Larry Cuban’s definition) of most schools will maintain the status quo by tweeking the new Standards into something that will pretty much look like the old Standards.  And, of course, we have business as usual.

The Math 2.0 vision as CLIME has been endorsing since 2009 means taking a bold, new direction outside the box. The pieces of the true 21st century "curriculum" are out there but don't as yet breathe life into learning. Yes, the Common Core can help to improve the teaching of algebra, for example. Hung Hsi Wu's ideas are well incorporated in them. His belief is that, if we just improve how we teach algebra using (his) better textbooks, then we will achieve the Standards. The answer lies not in getting the teaching of algebra done right or the books for that matter (there are plenty of traditionalist who think the texts were better in the 1950s) but rather envisioning curriculums that make algebra interesting, useful and empowering to students. The architecture for building this kind of "curriculum" has been around since John Dewey's day but is now becoming more “real” through the power of emerging technologies. Seymour Papert wrote in 1990 that the Standards at that time were a move in the right direction, but were way too conservative. Technology is changing the world around us, yet our schools stay stuck in the Standards Era where Algebra rules and is the gatekeeper to future success. Whats next when this lastest version loses its shine? A shinnier retread? Is that the best we can do?

We need to move in a direction of what of I like call the Wannado curriculum - paths of study for kids that they actually want to do. These paths can take on many diffferent forms where the math is learned from the “outside in.” In this model learning and teaching should:
  • go hand in hand. Teachers are mentors and advisors. They do not have to be subject “experts” but rather excited about the subjects they encounter and are learners themselves who model what it means to be a good learner. 
  • be student driven. Students have a much greater input into what they learn and how they learn it.
  • be project based. Students choose projects with the help of their teacher advisors where they can pursue meaningful activities.
  • offer needed feedback for both teachers and students. It should be performance based that shows competency (for both teacher and student) in the project they are working on. Bottom line: the teacher is an expert in learning. If a teacher doesn’t know something that’s pertinent to any activity she and students can research the answer. Effective Googling strategies are important 21st century skills.
Quality, genuine joint student and teacher journeys in learning should be THE core Standard for the 21 century. Emerging technologies make this more possible than ever before.

Note: I'm currently working on a book about the Wannado Curriculum. See a preview in my other blog.

I'm back from vacation to find out that I'm locked out! See you in September.


This is what I get for putting off the Mobileme demise deadline on June 30th.  They weren't kidding. Everything that begins with http://web.mac.com/ihor12... is now closed to me. I feel like I've been evicted. Until I get my act together those links on my resources pages that start with the above domain go nowhere. I may be up all night fixing this. To see what I mean click on this link:


7/12/12 - Starting to move all my files to http://dmcpress.org. It's going to take a while. Sigh. It would have been so much easier if I had done this in more timely fashion. Happy Vacation!!! See you September. -Ihor
