Is it better to use English electronic dictionary or paper dictionary?

If you are a primary or secondary school student, you should use a paper dictionary, that is, a paper learning dictionary. You can find word memorization and detailed usage on it. For example, in a good learning paper dictionary, the word tree will tell you that in the tree and on tree have different meanings. The electronic dictionary only tells you the Chinese meaning.

If you are a college student, the main purpose of looking up a dictionary is to look up new words in books and magazines, so it is convenient to use an electronic dictionary. It is enough to know a definition, and don't care too much about usage.
