Based on the information provided, it seems that Mrs. Edwards is exhibiting storytelling rather than scaffolding behavior. Scaffolding behavior refers to the instructional support provided by a teacher to help students gain understanding and complete a task. In the given scenario, Mrs. Edwards is reading a story to her class, using different voices for the characters, and then posing questions to facilitate discussion and deeper understanding of the story. This aligns more with the act of storytelling, where the teacher engages the students through narration and encourages reflection and analysis of the story.
