How and why does the children's point of view change over the course of the story? What lesson
or theme does this change convey

The children's point of view changes after experiencing sunshine for the first time and sympathizing with Margot's unique situation in "All Summer in a Day." Initially, the children were intolerant of Margot and locked her inside a closet when the sun came out. Tragically, Margot missed the opportunity to enjoy the sunshine. When the thunderstorms resume, the children regret their actions. Their change of perspective conveys the theme regarding the importance of exercising tolerance towards others.
