The document discusses dictionaries and their importance for language learning. It provides information on different types of dictionaries, including bilingual, learner, and monolingual dictionaries. It notes that dictionaries are not just tools for individual learning but can also foster classroom interaction. While teachers may assume students know how to use dictionaries, the document explains it is important to explicitly teach dictionary skills. Factors like student level, dictionary features, and classroom activities should be considered when deciding which dictionary to use. Dictionaries are most helpful for language study but may disrupt fluency in conversations. Teachers should look for opportunities to encourage dictionary use and integrate it throughout lessons.
