Final answer:
Cody's character shifts from being focused on mastering the yo-yo to teaching his dog to fetch and making a video of it. He moves from self-centered goals to forming a bond with Chester and from passively learning to actively sharing his experiences.
Step-by-step explanation:
From the beginning to the end of the story, Cody experiences a change in his focus and abilities. Initially, Cody cares solely about mastering the yo-yo, but as the story progresses, he develops new priorities. By the end of the story, Cody is not just more coordinated, as seen by his ability to throw the ball to Chester, but he has also shifted his attention from mastering the yo-yo to teaching Chester how to fetch. This indicates a growth in character, moving from a self-centered goal to forming a bond and investing time in his dog, Chester.
Another significant change is Cody's shift from consuming content to creating it. Whereas he starts the story watching videos on how to yo-yo, by the end, he takes on a creative role by making a video of Chester fetching. This demonstrates a shift from passive learning to active sharing, reflecting Cody's personal growth and a broader scope of interests.
