早在1989年,美国国家研究委员会发布的《人人关心数学教育的未来》便指出:优质的数学教育与经济发展关系紧密。虽然美国经济在全世界一直处于领跑地位,但近年来国际大规模教育测评(如PISA和TIMSS)的结果却表明,美国中小学学生的数学成绩仅处在中等或中等偏上水平,这引起了美国数学教育界的普遍担心。为此,美国数学教师委员会颁布了一系 As early as 1989, “Everyone cares about the future of mathematics education” issued by the National Research Council of the United States points out that quality mathematics education is closely linked with economic development. Although the U.S. economy has been a leader in the world, the results of large-scale international educational assessments (such as PISA and TIMSS) in recent years show that primary and secondary school students in the United States have only a moderate or moderate level of math performance, The general concern of the American mathematics education community. To this end, the American Mathematical Teachers Commission promulgated a series
