2023考研英语同源外刊12月文章:美国人的数学究竟有多差?

英语考研的备考,必须学生很多阅读文章外刊文章内容。由于阅读和理解考试真题里边的文章内容,大多数喜爱用外刊。因而,要想扩宽英文知识层面和改进外语水平,大家必须培养每日抽一点時间来说的习惯性!下面,我为众多2023研究生考试学生们得出-英语考研同宗外刊12月文章内容:美国人的数学到底有多差?供学生阅读文章。

2023英语考研同宗外刊12月文章内容:美国人的数学到底有多差?

America has a maths problem. Its pupils have ranked poorly in international maths exams for decades. In 2018, American 15-year-olds ranked 25th in the OECD, a club of mostly rich countries. American adults ranked fourth-from-last in numeracy when compared with other rich countries.

美国有一个数学难点。几十年来,其同学在国际性数学考题中的排行很差。2018年,美国15岁青少年儿童在经合组织(一个关键由富有国家构成的俱乐部队)国家中排第25。与别的富有国家对比,美国成人的计算水平排行倒數第四。

As many as 30% of American adults are comfortable only with simple maths: basic arithmetic, counting, sorting and similar tasks. American employers are desperate for science, technology, engineering and mathematics skills: nuclear engineers, software developers and machinists are in short supply. And while pupils’ maths scores are bad enough now, they could be getting worse.

高达30%的美国成人只能简易的数学:基本上的算数、记数、排列等专业技能。美国顾主急需解决科学合理、技术性、工程项目和数学专业技能:核技术工程师、APP开发者和驱魔者紧俏。尽管现如今美国学员的数学考试成绩早已够差的了,但将来很有可能会更差。

On the National Assessment of Educational Progress (NAEP), a national exam, 13-year-old pupils’ scores dropped five points in 2020 compared with their peers’ in 2012. The status quo does not add up. But teachers and academics cannot agree on where to go next.

在全国各地教育发展评定中,2020年13岁学员的数学考试成绩对比2012年的同年龄人降低了5分。这样的事情不合情理。但老师和专家学者们没法就下一步计划方案达成一致。

Since the 1990s, though, maths has become more political. Conservatives typically campaign for classical maths: a focus on algorithms (a set of rules to be followed), memorising (of times tables and algorithmic processes) and teacher-led instruction.

自上世纪90时代至今,数学越来越更为政治化。反对党通常适用經典数学:重视优化算法(一套必须遵循的标准)、记忆力(乘法表和优化算法全过程)和老师具体指导的课堂教学。

Pupils in these classrooms focus on the basics, exploring concepts after obtaining traditional skills, explains Bill Evers of the Independent Institute, a think-tank in Oakland. These methods are familiar to many.

堪培拉中国智库单独研究室的比尔·埃弗斯表述称,这种班里的学员致力于基本知识,在得到传统式专业技能后探寻定义。这种方式很多人都很了解。

For two-digit addition, pupils would be taught a paper-and-pencil method. Add 27 45 by stacking 27 over 45. Add up the right column (7 5 = 12). Write down the 2, and carry the 1 to the left column. Add up the left column (1 2 4 = 7). Write down the 7. The answer is 72.

针对二位数的加减法,学员们将学习培训一种纸技法。测算27 45时,将27写在45上边。将右侧一列累加(7 5=12)。把2记录下来,将1进位至左列。再把左列(1 2 4=7)加起來,记录下来7。最后获得回答为72。

Progressives typically favour a conceptual approach to maths based on problem-solving and gaining number-sense, with less emphasis on algorithms and memorising.

发展派通常趋向于以解决困难和得到数据感为基本的数学概念设计方式,而不太注重优化算法和记忆力。

In contrast to the conservative strategy, pupils would learn several ways to solve a problem, by using objects and by other means, before learning algorithms. To solve 27 45, pupils could add up the digits in the ones place (7 5=12), and then the tens place (20 40=60), and then add them together to get 72.

与反对党的对策反过来,在学习培训优化算法以前,学员们会根据应用物件或别的方式来学习培训解决困难的几类方式。要解27 45,学员可以把个位字之和(7 5=12)和十位数据之和(20 40=60)累加,获得72。

Or they could realise that 27 is 3 digits away from 30. They would add 3 to get to 30. Then add 45 and subtract 3 to get 72. Conceptual maths strategies encourage pupils to find many potential solutions for the same problem to gain number-sense, rather than relying on an algorithm.

或是她们也许会注意到27和30相距3。27再加上3就能获得30。随后再再加上45减掉3就能得到結果为72。定义数学对策激励大家为同一个问题寻找很多潜在性的解决方法,进而得到数据感,而不是取决于优化算法。

Although most teachers agree that maths education in America is sub-par, they have not been able to agree on how to improve it. Copying methods used in highly ranked mathematical nations such as Singapore would be one way. But that would require agreement on what is actually being taught in other countries.

虽然大部分教师都觉得美国的数学文化教育水准一般,但她们在如何提高数学文化教育水准的问题上无法达成一致建议。在其中一种形式是拷贝像马来西亚那样的数学排行靠前的国家应用的方式。但这必须就别的国家具体课程内容达成一致。

According to Mr Evers, successful Asian curriculums reflect the classical position. “What country do you think has totally adopted progressive education and has been a big success? China is very teacher-led. Singapore math is the best in the world. It’s not progressive,” explains Mr Evers.

埃弗斯表明,亚洲地区课程内容的取得成功体现了传统教育的影响力。埃弗斯表述道:“你认为哪一个国家彻底使用了发展文化教育并得到了很大的取得成功?我国的教育是以教师为核心的。马来西亚的数学在全世界遥遥领先,但其并没有选用发展文化教育。”
