VOCABULARY: NEEDED IF MORE CHILDREN ARE TO READ WELL

Vocabulary has long been recognized as a strong determinant of reading success. Despite the importance of vocabulary knowledge, very little information is available about effective strategies for vocabulary instruction in elementary grades and there is a paucity of data on the relative merits of the different programs that are designed to promote vocabulary growth in elementary children. Available information indicates that, until they reach about grade three, children’s vocabulary knowledge is largely determined by informal factors such as parental interaction and other incidental sources such as the TV. In this article, I will address the following topics: (a) individual differences in vocabulary acquisition, (b) the amount of vocabulary needed for successful learning, (c) the predictable sequence of vocabulary acquisition, (d) the need for direct instruction for vocabulary growth, and (e) promising methods for promoting vocabulary knowledge.
