学习IB物理的学生可能最头疼的就是IA了吧，IA是IB课程的内部评估，是非常重要的一部分，也占据着很大一部分的分数，想要拿高分，必须要重视IA，而做IA，选题非常关键，在教学大纲的范围内找到最好的IB物理IA主题并不容易。为了帮助大家更好的应对这部分，今天，留求艺留学为大家总结了IB物理IA选题方法及题目推荐，供大家参考！

一、IB物理IA选题方法

1、确定自己感兴趣的领域：可以浏览一下教学大纲，找出一个自己在课堂上学过的有趣话题，当然也可以是在课堂上没有涉及的主题，但是一定要是一个值得进一步研究的有趣问题。

2、选择一个可变的自变量：IB物理IA需要有一个重点研究问题，可以1500字的限制内探索的问题。 要构建一个合理的研究问题，首先需要想出一个容易改变的独立变量。请记住，选择的变量必须是可测量的。温度、时间、压力和质量都是很好的例子。记住要避免任何不连续的属性，如材料类型。

3、确定一个易于测量的因变量：因变量是在调整自变量时发生变化的量。要确保自己的因变量易于测量。

4、确保自己的研究问题是有意义的：选择合适的IB物理内部评估题目的最后一步是写下自己的研究问题。然后，阅读问题，确保这个研究是有意义的。
