學習IB物理的學生可能最頭疼的就是IA了吧，IA是IB課程的內(nèi)部評估，是非常重要的一部分，也占據(jù)著很大一部分的分數(shù)，想要拿高分，必須要重視IA，而做IA，選題非常關鍵，在教學大綱的范圍內(nèi)找到最好的IB物理IA主題并不容易。

為了幫助大家更好的應對這部分，今天，留求藝留學為大家總結了多個IB物理IA想法，如果你是來學習更多關于選題的知識，或者你只是因為還有時間而在尋找一個選題思路，那么你來對地方了！

如何選擇IB物理IA題目？

1、確定自己感興趣的領域

問問自己：在最近的一堂物理課上，什么話題激起了自己的興趣？自己對物理相關概念有什么愛好嗎？在空閑時間最喜歡做什么，并且很容易與物理聯(lián)系起來？

2、選擇一個可變的自變量

在這方面，需要有一個重點研究問題，這是將在1500字的限制內(nèi)探索的問題。要構建一個合理的研究問題，首先需要想出一個容易改變的獨立變量。這里的關鍵點是關于自己感興趣的話題的易變變量。請記住，選擇的變量必須是可測量的。溫度、時間、壓力和質(zhì)量都是很好的例子。記住要避免任何不連續(xù)的屬性，如材料類型。

3、確定一個易于測量的因變量

因變量是在調(diào)整自變量時發(fā)生變化的量。要確保自己的因變量易于測量。

4、寫下自己的研究問題

選擇合適的IB物理內(nèi)部評估題目的最后一步是寫下自己的研究問題。然后，閱讀問題，確保這個研究是有意義的。
