17 February 1997 Vol. 2, No. 7 THE MATH FORUM INTERNET NEWS DAU Tutorial | Undergrad Research | NCTM Standards: Proofs FEATURED INTERNET RESOURCE: DAU MATH REFRESHER TUTORIAL http://www.cne.gmu.edu/modules/dau/math/ The Math Forum's February 'hot spot' features this interactive tutorial, which gives a comprehensive view of basic mathematics. It includes practice problems and self-tests, covering: - arithmetic, fractions, exponents - logarithms, quadratic equations - series, functions, limits - graphing functions, derivatives, integrals Written for Defense Acquisition University (DAU) course participants, the tutorial can help students of any age with math at the middle school level and beyond. The Statistics Refresher Tutorial covers topics in basic probability (random variables, expectations, distribution) and statistics (regression, data analysis, clustering). http://www.cne.gmu.edu/modules/dau/stat/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- SUMMER AND OTHER RESEARCH OPPORTUNITIES FOR UNDERGRADS http://mathforum.org/students/undergrad.opps.html The National Science Foundation has recently posted a tentative list of sites, projects, and contact people for Research Experiences for Undergraduates (REU) for summer 1997. In addition, the Forum can help you find summer programs at the Argonne National Laboratory, the Cornell Theory Center for Supercomputing, the IAS/Park City Mathematics Institute, and the Army High Performance Computing Research Center (AHPCRC). We've also located a number of summer research opportunities exclusively for women. Don't wait to investigate these possibilities, since some applications are due the beginning of March. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- PROOFS AND MATHEMATICAL STRUCTURE A discussion from the NCTM-L archive hosted by the Math Forum http://mathforum.org/epigone/nctm-l/joizaxcran Do the NCTM Standards give short shrift to what is arguably the most basic and vital mathematical structure of all: proof? If so, does this constitute rejecting mathematical structure? In a previous discussion, "Parent's messages," a contributor suggested that readers search the Standards for occurrences of the word 'proof'. This conversation, "Proofs and Mathematical Structure," takes up the effect of the word's omission, the need for and value of precise mathematical arguments, the difficulty of translating everyday language into a form that can be analyzed, and the call for manuscripts addressing the role and nature of proof in a Standards-based curriculum. The NCTM Standards are available on the Web at http://enc.org/reform/journals/ENC2280/280dtoc1.htm -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problem of the Week http://mathforum.org/geopow/ Internet Resources http://mathforum.org/~steve/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__ /\ /| | \ \ / \ / \ /o\ / \ | \ / | / \ / \ |
