Bassetlover,
In reference to your daughter, you may enjoy reading about the scanner personality concept:

It's an interesting concept and very descriptive of myself, too. I see some other similarities in your descriptions. It sounds like your daughter is very intrinsically motivated. One of the things to counter boredom particularly with a strong inner passion for learning is to have your own learning objectives in classes. Grades then very rarely reflect the actual learning, but rather reflect an alignment between the learner's learning objectives and the teacher's pedagogical objectives.
