26 July 2004 Vol. 9, No. 30 THE MATH FORUM INTERNET NEWS REL Network | Pascal's Triangle From Top to Bottom Science.gov REL NETWORK http://www.relnetwork.org The network of 10 Regional Educational Laboratories, serving geographic regions that span the nation, works to ensure that those involved in educational improvement at the local, state, and regional levels have access to the best available information from research and practice. Each Laboratory's work is shaped by the concerns, issues, opportunities, and special attributes of its region. The Laboratories - Conduct development and applied research resulting in models for implementing systemic reform and for achieving improvement on a broad scale - Provide information, training, and technical assistance to help states, schools, and communities to implement comprehensive school improvement strategies - Promote widespread access to information regarding research and best practice - Create communities of learners who collaborate with the Laboratory in development and dissemination - Cooperate with other agencies and programs to deliver services that support efforts of educators and policy makers to improve education - Forge strong links to the research community to promote the creation of new knowledge to improve education The REL Network's site organizes information from the Laboratories into these sections: - Lab Stories Archive - Products and Publications - Search Products Database - National Leadership Areas - Contact Your Lab - Request Information -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- PASCAL'S TRIANGLE FROM TOP TO BOTTOM http://binomial.csuhayward.edu/ Matthew Hubbard and Tom Roby at Cal State University, Hayward, provide a comprehensive resource for the study of Pascal's Triangle. Their mission states: "There are many websites that deal with different aspects of Pascal's Triangle; our intention is to be as thorough as possible. We want the site to be useful to everyone from high school students and their teachers to graduate students and working mathematicians. Proofs and application pages will be given degrees of difficulty and if special knowledge is needed (or useful) to understand the math involved, it will be listed at the top." Areas of the site include: - Terms, Symbols, and FAQ - History - Applications and Applets - Identities and Proofs - Modern Algorithms - Reliable Resources - Other Websites - Stuff for High School Teachers - Recent Research \|/ PASCAL'S TRIANGLE - THE MATH FORUM http://mathforum.org/workshops/usi/pascal/ A Web unit designed to support workshops given by the Math Forum for the Urban Systemic Initiative (Philadelphia and San Diego). Read about the history of Pascal's triangle and learn to construct it; view illustrations of number patterns to be discovered; carry out interactive investigations in JavaScript or the Geometer's Sketchpad, and explore this famous triangle through lesson plans that feature questions, answers, discussion, and student worksheets. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- SCIENCE.GOV 2.0 - MATH, PHYSICS, AND CHEMISTRY http://science.gov/browse/w_129B.htm Science.gov provides public access and a unified search of the government's vast stores of scientific and technical information. It is an interagency initiative of 17 U.S. government science organizations within 12 Federal agencies. These agencies form the voluntary Science.gov Alliance. Visitors to the site can search across Alliance agency resources via one query. Each agency selects its best science information for science.gov. Two major types of information are included: - selected authoritative science Web sites - often hard-to-access scientific databases This gateway to government science information allows searches across 30 databases and more than 1,700 science Web sites. Science.gov currently accesses over 47 million pages of government science information. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pow/ Mathematics Library http://mathforum.org/library/ Math Tools http://mathforum.org/mathtools/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/discussions/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors Donations http://www.drexel.edu/ia/mathforum/ Ask Dr. Math Books http://mathforum.org/pubs/dr.mathbooks.html _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \
