A technique used to facilitate early literacy, which involves an adult and a child looking at a book together while the adult asks questions and encourages a dialogue, followed by switching roles so that the child asks questions to the adult, is called :

The correct option is Dialogic reading.

Step-by-Step Explanation:

1. Understanding the Concept:
The technique described involves an interactive reading experience where an adult and a child look at a book together. Instead of the adult simply reading the text aloud while the child listens passively, the adult actively engages the child by asking open-ended questions, encouraging dialogue, and expanding on the child's responses. Crucially, as the process continues, the roles switch, allowing the child to become the storyteller and ask questions to the adult.

2. Analyzing the Options:

• Storytelling: This generally refers to the act of sharing a story, often from memory or using a book, but it does not inherently imply the structured role-reversal and interactive questioning dialogue described.
• Model reading: This is a technique where an fluent reader (usually the teacher or adult) reads a text aloud to demonstrate proper pronunciation, phrasing, intonation, and pacing. It is primarily a one-way demonstration.
• Shared reading: This is an interactive reading experience where children join in or share the reading of a book while guided and supported by an adult. While interactive, it focuses more on joint reading of the text rather than the specific structured dialogue and question-asking role reversal.
• Dialogic reading: This term is derived from the word "dialogue." It is a specific method developed to promote early literacy, where the adult uses prompts to turn the reading session into a conversation (a dialogue) about the book. The key feature of dialogic reading is that the child learns to become the teller of the story over time, with the adult acting as an active listener and questioner, exactly matching the prompt's description.

3. Conclusion:
Therefore, the interactive technique that involves asking questions, encouraging dialogue, and switching roles so that the child asks questions is specifically known as Dialogic reading.
