Video lessons from the Trends in International Mathematics
and Science Study (TIMSS) are now freely available.
The 28 full-length videos of eighth-grade mathematics lessons
hail from Australia, the Czech Republic, Hong Kong, Japan, the
Netherlands, Switzerland, and the United States.
Each video comes with full English-translation subtitles, a
searchable transcript, and accompanying resources such as
scanned text materials and teacher commentaries.
Access requires free registration. In the nine days since the

A team led by Dr. Jim Stigler, Professor of Psychology at the
University of California Los Angeles, constructed and manages
the site. They plan to add features as requested, and so

PoW taking place: math problem-solving moment of the week
"If you're stumped on a problem like this, here is some
inspiration from some submitters who didn't finish solving the
problem, but had really great starts. Grant from Birch Wathen
Lenox school began with some great estimation. If everyone had
done this, I bet we would have gotten a lot more correct
answers.... Lucia from The Philadelphia School tried the
'Solve a Simpler Problem' strategy and imagined...."

Get the Math: Take the Challenge
Watch videos of young professionals in the fashion, videogame,
and music industries as they introduce four teenagers to
their emerging businesses, studios — and algebra challenges.
Fashion designer Chloe, who won season two of "Project Runway,"
asks the four teens to use proportional reasoning — and a
sense of style — to take apart a poly charmeuse top,
re-envisioning the sample shirt in a way that trims $5 off the
cost of its fabrics.
A developer of online games for Facebook and other websites,
Julia tasks the teens with programming a version of "Asteroids"
by drawing on coordinate graphing and linear equations.
DobleFlo hip-hop artists Manny Dominguez and Luis Lopez
challenge the foursome to adjust the tempo of an instrumental
sample to synch it up to a drum track, which requires
calculating beats per minute.
Compiled and edited in the style of reality-TV game shows,
these clips stop to let you try the math using the interactive
tools provided; then resume to show how the four adolescents
creatively applied algebra in these contemporary fields of art
For this program of WNET's THIRTEEN, DobleFlo recorded the
original rap "Get the Math." Download a free mp3 of the
Get the Math is distributed by American Public Television with
support from The Moody's Foundation.
Now taking place: math education conversation of the hour
"The results as measured by the Force Concept Inventory? Not
much difference. A bit higher, but not significantly different.
More pseudoteaching? Very different teaching, but not what I
was looking for in the form of results. Then I took a summer
course on Modeling Instruction. I modified my materials again,
used some of the Modeling instruction materials, created some
totally new stuff. The results...."

AIM's Math Teachers' Circle Workshops and Institutes
Apply now for the American Institute of Mathematics'
workshops and summer institutes on math teachers' circles.
First featured in these pages last March, AIM again offers
professional development opportunities that put middle school
math teachers in regular contact with mathematicians to work
on mathematical problem solving in the context of rich problems.
Almost half of the states in the union already have active
member circles, or plan to have them:
