I’ll Be On Al Jazeera’s The Stream With Sal Khan Tomorrow

I’ll be on Al Jazeera’s The Stream with Sal Khan tomorrow 10/2 at 3:30PM EDT as part of a segment on Khan Academy. You can watch live from their website if that’s what you’re into. I’ll update this post with the segment afterwards if that’s possible.

2012 Oct 3. Here’s a link to the entire broadcast. They give me two questions – one about the best use for those lecture videos in the classroom and the other comparing the Khan Academy model to math instruction in high-performing countries.

At first, Khan poses his lectures as a “first pass” or a “first scaffold” at new material. This is less effective and less engaging than a lecture posed in response to a precursor activity that sets students up to need that lecture and understand its context.

I pressed that angle in my second question and Khan then took a fairly agnostic approach to the instructional sequence. Basically, “do whatever works.”

Personalization is the point and Khan Academy has certainly figured out how personalize lecture delivery. But personalizing the precursor activity that sets students up to need those lectures is much, much harder. I didn’t get the sense from our exchange that that kind of personalization is anywhere on Khan Academy’s horizon.

Factor Dice

Kaleb Allinson, with a great end-of-class factoring exercise:

I tell my students that my dice add to 19 and multiply to 88 and ask them to guess my dice. I try to play this at the end of class for a week or two as I have time leading up to factoring. Then when they discover how to factor, this dice guessing skill is very helpful. They always realize what I’ve done and think I’m really tricky.

There are other ways to do this, of course, but the dice randomize the factors and I think that’s important. It says to the student, “Whatever algorithm you’re rolling around in your head right now – it’ll work for any whole numbers. The teacher isn’t putting her thumb on the scale. She’s giving you numbers she can’t control.”

Another extension is to ‘fake the dice results’ and have students determine whether or not there IS a solution to Kaleb’s problem; can they prove they have exhausted all possibilities?

Steven Leinwand for NCTM President

I voted for Steve Leinwand for NCTM President just now and I think you should do the same. He explains eight reasons for his candidacy on his website, which has this content license in the footer:

My mission is to promote progress in mathematics teaching and learning. Please use the material and resources on this site in any manner that facilitates the improvement of your mathematics curriculum instruction, assessment or policies.

So make that nine. Check your e-mail. Vote early. Vote often.

Kelly Berg:

After the Professional Development I spent with him this summer, I would vote for him to be President of the Universe!!! Seriously… Everyone needs to vote for this guy!!!

Nathan Kraft:

I love Steve Leinwand. His video is amazing. His book is amazing. He has already influenced my teaching greatly and I can’t thank him enough. He’s got my vote!

Molly Olson:

He is so inspiring, funny, smart and thought-provoking. I appreciated his speech last year at the WMC Green Lake Math conference. I would vote for him too!

Andrew Stadel:

Can we write Steve in for the November 6 Presidential election too?

My Edstartup 101 Materials

I’m enrolled in an online course taught by David Wiley, et al, called Ed Startup 101. Startup culture fascinates and frustrates me so I’m taking the course to learn more about it and, perhaps, to plant my own flag somewhere in the startup sand.

We’re supposed to tag and post assignments to a blog. Rather than turning this blog into my class scratchpad, I’ll be sequestering all those materials at edstartup101.mrmeyer.com, starting with an introductory post. You all tend to make me a lot smarter than I would be otherwise, so I wanted to invite you to tune in, subscribe, and comment. A little accountability would probably go a long way towards seeing me complete this course.

#MTT2K Contest Winners Announced

The judges’ prize goes to Michael Pershan’s What if Khan Academy was Made in Japan?, followed by Kate Nowak’s critique of Khan Academy’s lecture on the coordinate plane, and then to Susan Jones’ faithful homage to MST3K’s talking robots. Dr. Tae’s sharp critique of Khan Academy’s enthusiasm for gamification won the People’s Choice Award.

Each one is worth your while but special merits, again, to Pershan’s video which is optimistic, constructive, and exhaustively researched. He edits himself extremely well throughout the video, maintaining this unflagging narration that’s almost Ze Frankian. 13 minutes pass by in an instant. You should watch it, then subscribe to his blog, then follow him on Twitter, then visit him at his home.

Co-sponsor Justin Reich has his announcement over at Ed Tech Researcher. I echo his summary judgment:

Of course, the real winners of the competition are everyone who looked critically at Khan Academy (and looked critically at its critics) and developed a more nuanced view. If after reading some of the conversation generated about Khan Academy this summer, you have a stronger position that Khan Academy is [completely awesome/situationally useful/seriously problematic] then I’m pleased to have played a tiny role in nudging the conversation.
