Girls worse at Math?No Way,New Analisis shows girls can do just as well at math as boys-even at the genius level--if they are given the same opportunities,and encouragement,researchers reported recently.their study,pulished in the Proceedings of the National Academy of Sciences,contradicts studies showing girls can do as well as boys on average in math-but cannot excel in the way males can. they also said it is a clear rebutta to Larry Summers,who as presdent of Harvard University said in 2005that biologcal differences could explain why fewer women became professors of mathematcs."we conclude that gender linequality ,not lack of nnate apility or intrinsic apitude,is the primary reason fewer femaes than males are identified as excelling in mathematics performance in most countries,including the United States,"Janet hyde and Janet mertz of the University of Wisconin in Madison wrote in their report.
