2014年SAT數(shù)學(xué)考試變化分析

2014年SAT考試做出了一些新的調(diào)整，那么作為考試核心的SAT數(shù)學(xué)勢必就會產(chǎn)生新的變化。那么在2014年數(shù)學(xué)考試，變化有那些呢?今天今天跟小編一起來看下吧！

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

這里有三方面的內(nèi)容，問題解決和數(shù)據(jù)分析，核心代數(shù)，以及高等數(shù)學(xué)基礎(chǔ)知識。

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.

問題解決和數(shù)據(jù)分析包括運用比率，百分比和比例推理去解決一些現(xiàn)實生活中存在的問題，包括自然科學(xué)，社會科學(xué)和職業(yè)背景等方方面面。SAT考試中將不再出現(xiàn)與現(xiàn)實不相干的問題，那些非常具有技巧性的場景題目也將不再出現(xiàn)。

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

核心代數(shù)部分要求學(xué)生掌握線性方程和體系，這在很多學(xué)科的學(xué)習(xí)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 carefully add in more complex equations or functions and expressions, which open up fields like the calculus.

高級數(shù)學(xué)基礎(chǔ)是新SAT數(shù)學(xué)的第三部分。同樣，這一部分也能為學(xué)生帶去機遇。這一部分的數(shù)學(xué)題注重數(shù)學(xué)在科學(xué)研究，技術(shù)研發(fā)，工程，數(shù)學(xué)研究這些主要學(xué)科中的應(yīng)用。學(xué)生在未來的學(xué)習(xí)和工作中需要這樣的數(shù)學(xué)知識。

高級數(shù)學(xué)基礎(chǔ)部分會有選擇的加入更復(fù)雜的等式，方程，表達式，比如微積分的內(nèi)容。

There's 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's 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數(shù)學(xué)還有一個變化。就是，將與AP一樣，部分題目可以使用計算器，部分題目不能使用計算器。不能使用計算器的題目使我們能考察學(xué)生對于觀點的理解。這些題目對于熟練掌握數(shù)學(xué)技巧,計算和數(shù)學(xué)概念的學(xué)生更簡單。我必須強調(diào)，這樣做,對于美國的數(shù)學(xué)老師和數(shù)學(xué)家們來說意義重大。因為他們知道，數(shù)學(xué)不是簡單的按個按鈕得出結(jié)果。數(shù)學(xué)更重要的是理解。而不能使用計算器的題目能更好的幫助老師們加深學(xué)生對數(shù)學(xué)的核心知識的掌握。

最后，美國人終于意識到培養(yǎng)學(xué)生的計算能力是很重要的，數(shù)學(xué)不再可以全程使用計算器，新SAT會考察學(xué)生對于數(shù)學(xué)知識點的理解，掌握數(shù)學(xué)技巧, 計算和數(shù)學(xué)概念。較于之前的美國SAT考試，數(shù)學(xué)難度提高了。對于準備參加新SAT考試的中國學(xué)生來說，尤其擅長數(shù)學(xué)的同學(xué)，這當然是好事。最起碼，SAT試題的成績會占據(jù)大幅度的優(yōu)勢。
