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IB物理IA選題方法及題目推薦,供大家參考!

一、IB物理IA選題方法

1、確定自己感興趣的領域:可以瀏覽一下教學大綱,找出一個自己在課堂上學過的有趣話題,當然也可以是在課堂上沒有涉及的主題,但是一定要是一個值得進一步研究的有趣問題。

2、選擇一個可變的自變量:IB物理IA需要有一個重點研究問題,可以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。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、確保自己的研究問題是有意義的: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。
