ROBOTICS
http://www.thetech.org/robotics/
Robotics was designed to introduce the science behind the
design and operation of robots. After interacting with the
exhibit, the user will be able to:
- Define a robot as a machine that gathers information
about its environment (senses) and uses that information
(thinks) to follow instructions to do work (acts).
- Recognize the advantages and limitations of robots by
comparing how robots and humans sense, think, and act
by exploring uses of robots in manufacturing, research
and everyday settings.
- Understand the connection with technology and create an
excitement about science and math that will prepare one
for a workplace in which computers, robotics, and
automation are common and essential.
The exhibit has specific areas that compare how human and
robotic systems sense, think and act:
- Introduction
- Sensing
- Thinking
- Acting
- Applications
- Display and Demonstration Area
- Robots, the Workplace and Careers
Robotics at The Tech Museum of Innovation, San Jose, CA, was
funded by JPMorgan Chase & Co.

KSEG FREE INTERACTIVE GEOMETRY SOFTWARE
http://www.mit.edu/~ibaran/kseg.html
Ilya Baran offers KSEG, a free (GPL) interactive program for
exploring Euclidean geometry. Create a construction, such as
a triangle with a circumcenter; and as you drag vertices of
the triangle, watch the circumcenter move in real time
accordingly.
KSEG runs on Unix-based platforms and according to users, it
also compiles and runs on Mac OS X and should run on
anything that Qt supports.

REASSESSING U.S. INTERNATIONAL MATHEMATICS PERFORMANCE:
NEW FINDINGS FROM THE 2003 TIMSS AND PISA
http://www.air.org/news/documents/Release200511math.htm
Despite a widely held belief that U.S. students do well in
mathematics in grade school but decline precipitously in high
school, a new study comparing the math skills of students in
industrialized nations finds that U.S. students in 4th and
8th grade perform consistently below most of their peers
around the world and continue that trend into high school.
The study, conducted by the American Institutes for Research
(AIR) under funding provided by the U.S. Department of
Education, reexamined data from three international surveys
assessing mathematics achievement in 2003 -- the Trends in
International Mathematics and Science Study (TIMSS), which
assessed students in grades 4 and 8, and the Program for
International Student Assessment (PISA), which assessed
15-year-olds, most of whom were in 10th grade.
