Students in a content-area reading course examined the vocabulary of each of their disciplines, focusing on recurrent roots and affixes. They wanted to become teachers of math, science, English, music, and history; therefore, they needed to learn discipline-specific morphemes so they could help their future students figure out new words in their content areas. The students: (1) analyzed words in their disciplinary vocabularies, using recurrent roots and affixes to aid in comprehension of word meaning; (2) adapted traditional reading strategies for disciplinary use; (3) discovered that many roots and affixes which were seemingly particular to one discipline also contributed to the meanings of words in other disciplines; and (4) designed content-area lessons using a morphemic approach. The class learned that teaching the meanings of morphemes could improve disciplinary literacy and could also help with vocabulary in other content areas.
