Searching for Better Ways to Teach Math in US (2/2)
Schools are urged to prepare more students to take algebra by the eighth grade.Many people think math success depends largely on natural talent or ability; the experts say it depends on effort. Studies have shown that children improve in math when they believe that their efforts to learn make them "smarter."
The report also calls for strengthening the math preparation of elementary and middle school teachers. And it urges publishers to shorten math textbooks, which are often up to a thousand pages long. The panel said math books are much smaller in many nations where students do better in math than American children.
Publishers say American textbooks have to meet the goals of different states for what should be taught in each grade.The report also calls for more research on the effects of using calculators. Many algebra teachers expressed concern about their use in the lower grades. And the report says gifted students who can move through the material much faster than others should be permitted to do so.
The math panel says the educational system needs major changes. If not, it warns that the United States will lose the mathematical leadership it possessed during most of the twentieth century.
参考译文:
(报告)督促学校让更多的学生8年级时学习代数。很多人认为学好数学很大程度上依赖于人的天赋和能力。而专家则认为它取决于努力。研究显示当孩子们相信他们的努力学习可以使自己变得聪明时,他们的数学水平都有了进步。
报告还呼吁加强数学方面初、中级学校老师的储备。而且小组还要求出版商精简总是厚达一千页的数学教科书。小组说很多国家的数学书都薄许多,但他们的学生比美国学生的数学好。
出版商认为,不同的年级需要教授不同的内容,有着不同的教学目标,而美国的教材正需满足不同州不同阶段的需求。同时报告也呼吁对使用计算器的效果进行更多的调研。很多代数学老师对低年级学生使用计算器表示了忧虑。报告说应该允许比其他同学更快领会学习材料的天才学生这么做。
这个数学小组认为教育系统需要重大的改变,如果不改变,小组警告说美国可能将失去在20世纪数学领域一直保有的领导地位。
