* Expansion: This is a common term used in child language development. It involves adding grammatical elements to a child's utterance to make it a complete sentence. For example, if a child says "Dog bark," an adult might expand it to "The dog is barking."
* Recasting: This is a broader term that encompasses expanding, but also involves rephrasing the child's utterance in a different grammatical structure. For example, if a child says "Me want juice," an adult might recast it as "You want some juice?"
* Modeling: This is a more general term that refers to providing children with examples of correct grammar and sentence structure. This can include both expanding and recasting, as well as simply speaking in complete sentences around the child.
* Scaffolding: This is a broader concept that refers to providing support for a child's learning and development. It includes expanding, recasting, and modeling, as well as other strategies like providing cues and feedback.
In essence, the process of changing a child's utterance into a sentence is about providing language input that helps the child learn the rules of grammar and develop their ability to speak in complete sentences.
