Proverbs are fixed expressions based on practical experience or common sense. People of a particular language use them to effectively express their thoughts and ideas. If you are a native or a non-native speaker of English, it is better to learn them and use various idioms in your oral or written communication.

This depends on in what subject your Masters is in. If you are studying a Masters in History - then you studying English idioms would probably not be very useful :)

Please remember education has no ends.

Terminology knowledge is really important. English is the language of science and learning is a continuous process of course.

It really depends on their educational needs. Idioms are not only important from the linguistic point of view - they are also culturally, psychologically, sociologically , historically...interesting.
