Do your English learners stop when they encounter a new word? Do they immediately pull out their phone to use translator or dictionary? This is what I encounter when I teach adult intermediate and advanced ESL courses. My students appear to be relying on methods they learned in beginning levels of English that are not appropriate or effective for higher levels. Stopping for new words interrupts their comprehension of the text as a whole and makes reading a slow and tedious process.
As a result, I began to teach intermediate and advanced English language learners techniques for defining New Words using context. The goal is for students to read English using their first language skills. One rarely consults a dictionary when reading their first language. They guess the meaning from the context. If that doesn't work, they ask a family member or friend for the definition. So, I encourage and teach my adult ESL students to read English tests in the same manner. They learn to guess the meaning in context and ask their classmates for the definition of new words. Of course, the dictionary is available if needed. However, the multiple definitions can be confusing and unhelpful for many English learners.
I regularly use the New Words chart to teach/review how to define new vocabulary in context. These are first language strategies which many students already know and use. Often these strategies are not transferred when reading their nonnative language. It is necessary to review and demonstrate these techniques many times, particularly at the beginning of a term. By asking appropriate questions such as, "What part of speech is this word? Do you see a synonym or antonym near it? Can you substitute a word that makes sense? Is there a prefix, root, or suffix?" students learn to use new word definition strategies.
