Back to the Future: Teaching Math With Web 2.0 (BYOL)
by ihor Charischak, Council for Technology in Math Education

[my notes on my Pulse Pen]

Ihor was ill and taken to the hospital in Washington the night before his session so his friend, David Weksler, covered for him. These are the projects that were planned to be part of the presentation.

His agenda:

1. The Average Traveler
Ihor planned to have us find the average travel distance is for all the participants who came to this session?

2. Stock Market
A simulation designed by Mr. Charischak for 6th grade students to help them understand the New Jersey Stock Market.
additional site:

3. Shopping Spree
Students are giving a party and have to go shopping for snacks. They use an online spreadsheet to do their analysis and share their results with others.
4. The Noon Day Project: Measuring the Circumference of the Earth
Participants from around the world recreating the experiment that Eratosthenes tried 2200 years ago using shadow measurements to determine the circumference of the earth. Javasketchpad applets are used to explain the math. (See )

5. The Great Green Globs Contest
Students build their algebra and graphing skills as they pursue a high score by hitting as many objects (globs) on a Cartesian coordinate system with the fewest number of linear or non-linear equations. See

My notes are on my Pulse pen. Some links and thoughts are below.

In an email sent to me by the presenter he wrote:

NCTM recently announced their new guidelines for Curriculum and Assessment and the document did not make any mention of technology. (See my blog entry: concerns me a lot and I think there needs to be a vehicle for making our concerns be better understood by the NCTM community and all those educators who yearn for a day when mathematics is no longer the great unloved subject, but one that students can see as not only useful, but also interesting and empowering. Each day I discover a new site of individuals and groups of people that are energized enough by Web 2.0's potential in Math to write blogs, set up social networking sites, etc. in hopes of empowering folks to share what they are doing to make this potential reality.

One of these individuals Maria Droujkova (// is planning to be interviewed by Steve Hargadon next week to discuss the question "What is Math 2.0?" and it seems to me that that moniker is a natural contraction for Math AND Web 2.0 which removes the confusion about it being just a software upgrade.

I hope you join us on what I see as an ongoing adventure as we work together on creating the new 2.0 version of the math classroom (Math 2.0).
