The brain is wired to remember stories and to use the story structure to make sense of the world. That’s why every culture has creation stories. In oral traditions, stories play a bigger role in teaching lessons about manners, morality, or simply what plants to eat or not eat in the wilderness because it’s the way content is remembered.
Diverse students (are all students, really) learn content more effectively if they can create a coherent narrative about the topic or process presented. That’s the brain’s way of weaving it all together.
