vocabulary teaching

I have tried several different methods in learning vocabulary.
One traditional way of learning vocabulary is to just to write down on a paper as you memorize each vocabulary from the vocabulary list. Keep going until you finish the book.
This could easily get the students to be bored, and tired, exhausted from memorizing, just like memorizing lots of grammar rules.
One method I like to use is to memorize the synonyms and antonyms as I memorize each word. At first, it may get you tired because you have to personally take the effort to find all the synonyms and antonyms (if it is not listed in the book), and it takes longer time to memorize one word. However, as you go through this practice, you will find yourself memorized lots of vocabulary that are related. This will affect your English skills, all speaking, listening, reading, and writing. In writing, you can choose different, difficult words because you don't want to repeat the same words over and over again. This could make you smart. As you memorize this way, as you memorize more words, you will find that you have memorized many of them already, they are all connected or related. You would find yourself very smart. Later, when you think of a word, you will be able to say outloud lots of its synonyms and antonyms. I think this method is very practical and useful for the future.
