Which of the following is an appropriate way to prompt for more language during incidental teaching?

Providing a full verbal model is an appropriate way to prompt for more language during incidental teaching because it directly offers the child a clear example of the language or phrase you would like them to use. By modeling the complete response, you set a standard for the child to imitate, promoting more extensive verbal interactions.

In the context of incidental teaching, the aim is to encourage language development through naturalistic opportunities. When a full verbal model is used, it helps to expand the child's vocabulary and structure while reinforcing the specific context in which the language might be used. This approach supports language learning by contextualizing the model within a meaningful interaction, making it easier for the child to grasp and replicate.

Other methods, such as giving a single word option or asking yes or no questions, tend to limit the opportunity for the child to develop their language skills. These approaches might prompt minimal responses and do not encourage the child to engage in more complex conversational language. Waiting for spontaneous language, while beneficial in its own right, may not provide the immediate scaffolding that a full verbal model does, particularly when aiming to elicit more detailed responses.
