教育学在英语中的说法是：education.

教育学的来源可以追溯到古希腊时期，当时它被称为"学问"（"paideia"）。在拉丁语中，它被称为"educatio"，意思是"培养"、"训练"或"抚育"。这个词最终演变成了现在在英语中使用的"education"。

一些英文例句如下：

She studied education at the University of Cambridge.

He has a Master's degree in education.

The government is investing more in education.

Education is the key to success.
