Breaking down words to build meaning: morphology, vocabulary, and reading comprehension in the urban classroom: when it comes to teaching vocabulary, a little knowledge (of root words, prefixes, and suffixes) goes a long way.

Summary: The authors describe the challenges faced by students who have limited academic vocabulary. These students struggle with comprehension as texts increase in complexity. When teachers combine explicit instruction with decoding strategies, students will increase vocabulary skills. The authors break down the meaning of morphology and apply it to instruction.
