Encouraging Vocabulary Usage

General notes on encouraging vocabulary usage with young children:

  • The goal of introducing Computer Science related vocabulary to young children is to have them begin to incorporate the words naturally into their conversations and explorations; not to simply memorize vocabulary.
  • The more children hear these vocabulary words used in the context of activities, the more they will begin to use these words correctly on their own. Reinforce vocabulary throughout daily activities, like naming “objects” as you are working with math manipulatives, or “detecting” something out of place during clean up time.
