Myth 7: The best dictionary for second language learners is a monolingual dictionary.
Research shows that dictionary use is an essential skill in learning a new language. Many teachers tolerate the use of bilingual dictionaries with the goal of learners using a monolingual dictionary as soon as possible. There is absolutely no empirical evidence to support this. Dictionaries allow students opportunities to learn polysemous words. Bilingualized dictionaries are the best for ELLs. Bilingualized dictionaries include the word in English, an English definition, a L1 definition, and an example of the word used in a sentence.
