  很多同学都了解,爱德思A-level物理培训在今年六月份的考试中AS部分全部采用了新大纲。考试结果真是几家欢喜几家忧,今天学通国际教育老师为大家分析10-11月爱德思A-level物理培训考试情况。

10-11月爱德思考生必看! A-level物理培训考情分析

  就整体而言,新大纲的unit 1和旧大纲基本类似。

  新大纲试题包含了,Vector notation (大纲第四点), conservation of momentum in 1 direction (specification point 14), moments (specification point 15), and the efficiency equation (specification point 30)。

  新大纲包含了3个核心实验,to determine the acceleration of free-fall, to use a falling ball method to determine the viscosity of a fluid, and a method to determine the Young modulus of a material。

  这三个实验虽然在之前也考察,但属于optional的实验,现在是compulsory。

  Topic 2 Materials部分的fluid flow diagrams不再考察。

  Material属性的描述如:brittle, ductile, hard, malleable and touch不再考察。

  1月份考试季Unit1的Grade A线为43分,6月份的A线为42分。

  就整体而言,Unit 1在1月份17.9%的学生可以拿到A。

  6月份21.2%的学生可以拿到A。

  对比下来,6月份Unit 1的题难度有稍稍降低。

  那么同学们怎么来应对10/11月份的考试呢?我们参考以下examiner report上给出的总结:

  1、Candidates who had a soundunderstanding of the physics involved did not always demonstrate this in their responses due to a lack of precision of the language and terminology used. Some missed exactly what the question was actually asking.

  学生明白理论,但不能正确及其准确的应用理论。

  2、A greater understanding of the context and question being asked would have helped many candidates. Asoundknowledgeof thesubject was evident for many, but the responses seen did not reflect this as the specific question was not always answered as intended.

  学生需要更好的理解题目语境及问题。很多学生虽然理解相关知识,但答案并没有反应出来。

  3、Make sure that the core practicalsare covered thoroughly; there are usually recall questions asking fordetails of these practicals.

  核心的practicals需要彻底的掌握。

  4、Practice using equations to determine the area of a circle and the volume of a sphere and extend this practice to correct use of the density equation and for up thrust calculations.

  更加熟悉公式的使用及展示解题步骤。

  5、Practice longerexplanations paying particular attention to the structure and making sure that the points mentioned link together wherever possible.

  练习回答简答题,特别注意回答的结构性。确保每个得分点都能拿到。

  6、Invest time when a large amount of information is presented in a question; read the question so that the context is fully understood before answering the question.

  当题目特别长时,花一定的时间来审题,确保完全理解题目。

  7、Make sure that all working out is shown in higher mark calculations so that credit for interim working can be given if arithmetic or power of ten errors are made.

  确保所有展示的答案,步骤清晰,得分点清晰。

  总的来说,爱德思的物理并不难,注意审题以及使用知识的准确性很重要。比如,question 11。

  使用conservation of momentum来解释问题时,需要注意准确叙述:total momentum before collision equals to the total momentum after collision, provided no external force is applied。

  在这里,如果学生忽略掉了total 这个单词,那么整个叙述就拿不到分数了。Examiner 有充分的理由认为缺了total表明学生对该知识点没有理解透彻,知识点没有精确的应用。
