Why meaningful math problems are defined out of online assessments

Dan Meyer said:

at this moment in history, computers are not a natural working medium for mathematics.

For instance: think of a fraction in your head.

Say it out loud. That’s simple.

Write it on paper. Still simple.

Now communicate that fraction so a computer can understand and grade it. Click open the tools palette. Click the fraction button. Click in the numerator. Press the “4″ key. Click in the denominator. Press the “9″ key.

That’s bad, but if you aren’t convinced the difference is important, try to communicate the square root of that fraction. If it were this hard to post a tweet or update your status, Twitter and Facebook would be empty office space on Folsom Street and Page Mill Road.

It gets worse when you ask students to do anything meaningful with fractions. Like: “Explain whether 4/3 or 3/4 is closer to 1, and how you know.”

It’s simple enough to write down an explanation. It’s also simple to speak that explanation out loud so that somebody can assess its meaning. In 2012, it is impossible for a computer to assess that argument at anywhere near the same level of meaning. Those meaningful problems are then defined out of “mathematics.”

In many cases your student peers aren’t burdensome, they’re essential

Dan Meyer said:

most software for individualized instruction fails to connect learners in the kinds of productive debates Brendan describes. And that’s by design. Individualization is the watchword. Don’t let yourself become burdened by your classmates! But in many cases your peers aren’t burdensome. They’re essential. And the software fails to distinguish one case from the other.

If you’re functionally equivalent to a YouTube video…

Dan Meyer said:

Teachers are a great medium for lots of things that a YouTube video isn’t. “Conversation, dialogue, reasoning, and open questions,” as I put it in my post. If you, as a teacher, aren’t taking advantage of your medium, if you’re functionally equivalent to a YouTube video, you should be replaced by a YouTube video.

A Japanese approach to Khan Academy

Got 13 minutes? Watch this video from Michael Pershan. Plain and simple, American math teachers teach differently than Japanese (and other international) math teachers. What would Khan Academy look like if it came from Japan? Well, it would look more like the work that Dan Meyer’s doing

Michael’s video was the winner of the #MTT2K prize. Happy viewing!
