2017年SAT数学考试有什么变化.

　　2014年SAT考试做出了一些新的调整，那么作为考试核心的SAT数学势必就会产生新的变化。那么在SAT试题中，SAT数学的变化有那些呢?请看详细内容：

　　There are three areas, focuses of math, problem solving and data analysis, the heart of algebra and passport to advanced math.

　　这里有三方面的内容，问题解决和数据分析，核心代数，以及高等数学基础知识。

　　Problem solving and data analysis include using ratios, percentages and proportional reasoning to solve problems in real world situations including science, social science and career context. No longer will the SAT only have disconnected problems, or tricky situations that students won’t likely see again.

　　问题解决和数据分析包括运用比率，百分比和比例推理去解决一些现实生活中存在的问题，包括自然科学，社会科学和职业背景等方方面面。SAT考试中将不再出现与现实不相干的问题，那些非常具有技巧性的场景题目也将不再出现。

　　The heart of algebra, focuses on mastery of linear equations and systems which echo throughout many field of study.

　　核心代数部分要求学生掌握线性方程和体系，这在很多学科的学习中都用得到。

　　The passport to advanced math is the third area on the SAT. And once again, it is the math that opens doors of opportunity. These problems on the exams focus on the math you need to pursue further study, in disciplines like science and career opportunities in the stem field of science and technology, engineering and math. The passport to advanced math section will carully add in more complex equations or functions and expressions, which open up fields like the calculus.

　　高级数学基础是新SAT数学的第三部分。同样，这一部分也能为学生带去机遇。这一部分的数学题注重数学在科学研究，技术研发，工程，数学研究这些主要学科中的应用。学生在未来的学习和工作中需要这样的数学知识。

　　高级数学基础部分会有选择的加入更复杂的等式，方程，表达式，比如微积分的内容。

　　There&aposs one other change in the math section of the SAT. As College Board has done in advance placements assessments, there will be now calculator and non-calculator sections on the SAT. The non-calculator section makes it possible for the SAT to assess the students understanding these ideas. It rewords well-learned techniques, fluency with calculation and number sense. This is so meaningful, I must tell you, for math teachers and for mathematicians in this country. Because they all know that mathematics is not just plug in solutions into an answer. It&aposs understanding the work in front of you. And the non-calculator section really allows us teachers accelerate their cultivation of that core technique in understanding.

　　SAT数学还有一个变化。就是，将与AP一样，部分题目可以使用计算器，部分题目不能使用计算器。不能使用计算器的题目使我们能考察学生对于观点的理解。这些题目对于熟练掌握数学技巧,计算和数学概念的学生更简单。我必须强调，这样做,对于美国的数学老师和数学家们来说意义重大。因为他们知道，数学不是简单的按个按钮得出结果。数学更重要的是理解。而不能使用计算器的题目能更好的帮助老师们加深学生对数学的核心知识的掌握。

　　最后，美国人终于意识到培养学生的计算能力是很重要的，数学不再可以全程使用计算器，新SAT会考察学生对于数学知识点的理解，掌握数学技巧, 计算和数学概念。较于之前的美国SAT考试，数学难度提高了。对于准备参加新SAT考试的中国学生来说，尤其擅长数学的同学，这当然是好事。最起码，SAT试题的成绩会占据大幅度的优势。
