Teachers have discovered that proprietary vocabulary acquisition by elementary students is enhanced through participation in a creative, thematic approach to learning. Proprietary vocabulary is a collection of words over which the owner has mastery of understanding in listening and reading and mastery of use in speaking and writing. This definition is based on the meaning of proprietor, an owner who has mastery and control over a possession, and vocabulary, a stock of words.
