What is the science of teaching known as?

Do you mean that what does science teach us?

If so, it teaches the mankind that nothing in this world is permanent. Only change is the thing which permanently happens. So in the changing word, try to live without harming others. Try to help the needy if possible. If not at least do not disturb others.

Use the modern invention of science judiciously, over usage of anything will harm the self as well as the community.

Good wishes
