In an effort to build students' academic language, educators are incorporating increasingly complex texts into their lesson plans. With College and Career Readiness standards emphasizing the acquisition and use of general academic and domain-specific words and phrases, students are encouraged to find the meaning of unfamiliar vocabulary by choosing flexibly from a range of strategies. One strategy is the use of a variety of reference materials, while another involves applying knowledge of the structure of words and parts of words, such as stems, root words, prefixes, and suffixes. Here, we'll focus on helping students develop the ability to use the context of an unfamiliar word—i.e. the text surrounding it—as a clue to the word's meaning.
