Helping students build their Vocabulary helps them understand what they are reading. When readers come across unfamiliar words, comprehension breaks down. Learning strategies for figuring out new words is a critical step to becoming a fluent reader.

Main Ideas

Vocabulary knowledge involves stored sound patterns (phonology) and mental representations of meanings.

There are four distinctions within a learner's Vocabulary.

  • Vocabulary Breadth is the number of words for which the student has at least a superficial understanding.
  • Vocabulary Depth is the extent to which the student knows words' properties, including definitions, spelling, pronunciation, and syntactic and morphological properties.
  • Receptive Vocabulary are the words understood by the listener.
  • Productive/Expressive Vocabulary are the words appropriately produced in context by the speaker.

Typically, Vocabulary growth is relatively slow until a learner has 50-100 Productive/Expressive Vocabulary words, usually at the end of the second year of life. At this point, a sudden jump in development ("vocabulary spurt") is common where learners add 10-20 new words per week.
