Searching for a short, paperback, sci-fi book assigned in my 6th grade English class in 1978 about a boy named Jon who might have fallen in a hole by a tree. He had amnesia and was from another planet. Sorry, that’s all I can remember.

Lost in an unfamiliar world, a traveler searches for understanding
At night, Little Jon’s people go out to watch the stars. Mesmerized by a meteor shower, he forgets to watch his step and falls through a moss-covered door to another land: America. He awakes hurt, his memory gone, sure only that he does not belong here. Captured by a hunter, Jon escapes by leaping six feet over a barbed-wire fence. Hungry and alone, he staggers through the darkness and is about to be caught when he is rescued by a kind family known as the Beans. They shelter him, feed him, and teach him about his new home. In return, he will change their lives forever.
Although the Beans are kind to Little Jon, the townspeople mistrust the mysterious visitor. But Jon has untold powers, and as he learns to harness them, he will show his newfound friends that they have no reason to be afraid.
This sounds like The Forgotten Door, by Alexander Key
