However, the relationship
between oral vocabulary and reading is reciprocal; once children have acquired foundational reading skills, the reading process provides them with opportunities to learn new words.
They build their
vocabulary, acquire conceptual knowledge, learn about letter - sound relationships and the relationship
between oral and written language, and practice the skills necessary to become automatic and fluent readers who can tackle the more specialized and technical texts of secondary reading (Chall, 1983; Chall & Jacobs, 1996; Jacobs, 2000).
