Data Sleuthing

Apr 4, 2013 by

Khan Academy Idaho is a grant-funded initiative to help K-12 teachers in Idaho integrate digital devices and the Khan Academy program into their math classrooms. Yesterday I gave a keynote there called “Between a Rock and a Hard Place” about (1) the challenges facing math educators and (2) Data Sleuthing, a way to encourage math curiosity and data literacy in students.

Best of the Ed Tech Freebies!

Jan 26, 2010 by

In a “pilot” program, we used Camtasia to record several sessions at the 2009 AMATYC Conference in Las Vegas.  Several of these recordings are now available on the AMATYC 2009 Conference Proceedings Website.

In particular, you might want to check out my live presentation “Best of the Educational Technology Freebies” … at least, you can check out the first 24 minutes of it (before my spectacular graphics-overload-induced red-screen-of-death computer crash).  The live presentation starts approximately 1 minute into the video.

There is a Part II (audio with a few PowerPoint slides – all my computer was capable after burning up the graphics capability temporarily), but I guess they haven’t put it up yet.  Update: Part II is now also available here.  Incidentally, this incident sealed the deal on my getting a new tablet PC (I was running with the memory capacity and hard drive maxed on the old one).

Word to the wise: You should not attempt to simultaneously record new audio narrative for a Camtasia video project running in the background, while running that video in a player on the notebook and projecting to a screen.  Sure, it works for 5 minutes, but will it work for 60? [no, unless you have a really powerful computer and graphics card]

The easy way to find all the recorded videos from the 2009 AMATYC Conference is to search the Conference Proceedings website (Ctrl-F for find) for the word “flash” (as in Flash video).

Teaching Math with Technology (Discussion Panel)

Dec 3, 2009 by

While I was at Wolfram Alpha Homework Day, I participated in a Panel Discussion about the Myths about Teaching with Technology. The panel ran 30 minutes and was mediated by Elizabeth Corcoran. There were three of us (all women, weirdly enough), Debra Woods, a mathematics professor at the University of Illinois at Urbana-Champaign; Abby Brown, a math teacher at Torrey Pines High School; and myself.

I no longer remembered anything that I said in this panel, so it was fun to watch the discussion from an outside point-of-view. I am glad to see that I talked about the value of play during the discussion, because I am finding more and more that introducing play (and exploration) back into learning makes a big difference in engagement and in retention of the subject.

eLearning Tools for STEM

Oct 6, 2009 by

For anyone who has ever had trouble convincing your administration to give you the proper tools to teach online, I give you this little gift: eLearning Tools for STEM, published today in eLearning Magazine.

elearning-tools-for-stem

The tools for STEM eLearning

  1. Tablets
  2. Recording & editing software
  3. Jing
  4. Equation software and training
  5. Synchronous communication system
  6. Online homework system

Other head-turning resources for STEM

  • Wolfram Demonstrations
  • Digital libraries (a lengthy list)
  • Video collections (another list)
  • TI-SmartView

Other tips (about accessibility, computer labs, etc) can be found at the end of the article.

You can read about all the tools, and why I recommend them, by going to the article, eLearning Tools for STEM.

Interactive Simulations from PhET

Oct 2, 2009 by

PhET (Physics Education Technology) consists of a group of scientists, software engineers, and science educators from the University of Colorado at Boulder, who are striving to create effective, interactive learning tools.  Their work spans the fields of physics, biology, chemistry, earth science, and mathematics.  Much care has been taken in the design of each simulation.  The developers use a research-based  strategy to implement the most effective visual cues for learning.  User-interviews are held routinely.   Members of PhET have learned that animated responses are effective, as well as,  the use of a “click and drag interface”.  There’s more:  each simulation comes with lesson plans that have been submitted by instructors.  The simulations are free and require flash and java to run.

Here is an applet on estimation:

Here is Calculus Grapher, which shows the relationship between a function and its derivative.

And a Plinko Probability applet that shows a histogram that approaches the Binomial Distribution.
