November 28 2005 Vol. 10, No. 48 THE MATH FORUM @ DREXEL INTERNET NEWS Robotics | KSEG Free Interactive Geometry Software Reassessing U.S. International Mathematics Performance 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.
