Bruce Baker wants to analyze educational reforms correctly
Meet The @FiveThirtyEight Of Education. Bruce Baker Will Bring Sanity To Reform Hype
Stop Cheerleading Education Miracles, i.e. Education Effects Are Small
āWe really have failed in the teaching of mathematics and probability,ā decries Baker, who regularly debunks myths about unicorn policy changes that radically improve student outcomes. At scale, experiments rarely move the needle more than a few percentage points. Statisticians measure outcomes in āstandard deviationsā, or how students move relative to their peers.
I’ve added his blog to my RSS reader. Unfortunately, it seems that for policy
makers the only data that is good is data that confirms their own beliefs. -
Giving technical presentations
Presentation Zen: No excuse for boring an audience: Advice on giving technical presentations:
Long before “death-by-powerpoint” or vertigo-by-prezi, there were bad presentations. Really bad presentations. So don’t blame the software. The genesis of painfully dull or muddled presentations predates the computer. No one knows this better than scientists, researchers, and academics, who have long been required to attend numerous conferences each year, conferences which typically feature a keynote speaker and scores of shorter presentations by others in their field.
At least I rarely see bullet lists…

Seventy WPM typists can’t tell you where keys are on the QWERTY keyboard
Typists who clear 70 wpm canāt even say where the keys are
The majority of typists couldnāt tell you how they type if they tried, according to a study published in October in the scientific journal Attention, Perception, and Pschyophysics. The finding comes from a body of typists who averaged 72 words per minute but could not map more than an average of 15 keys on a QWERTY keyboard.
I know I don’t think about where the keys are, I just type. Anytime I take a
typing test, if they don’t use words and just random letters I do worse. -
If anyone needs an idea on what to get me for Christmas
Harrison Ford “Han Solo” DL-44 Blaster from Star Wars
Particularly noteworthy scenes requiring this lighter version are when Darth
Vader uses the Force to lasso the blaster out of Hanās hand in Empire, and in
Jedi when Han wrestles with a Stormtrooper to regain possession of his blaster
during the Rebelsā encounter with Imperial forces on Endor.This would be awesome!

Math tricks
We are committed teachers who want to take the magic out of mathematics and focus on the beauty of sense-making. We wish for teachers everywhere to seek coherence and connection rather than offer students memorized procedures and short-cutting tricks. Students are capable of rich conceptual understanding; don’t rob them of the opportunity to experience the discovery of new concepts.
It’s a free eBook about the math
tricks that masquerade as teaching concepts. I have mixed feelings, it seems
like I use a lot of tricks. But at the same time, I do understand the concepts
and why the trick works. Maybe that’s the difference?Via: dy/dan
