Often when we think of tutors, we think of the struggling student. But what about the exceptional student? The student years above his/her grade level?
Maybe your student is years above YOUR knowledge level (think Calculus or Physics).
Tutors can be the answer.
So how is the gifted child tutored? Probably with inquiry-based approaches and approaches that emphasize multiple solutions or multiple paths to the same solution (s). Creativity is stressed, rather than learning by route.
Sit in on a few sessions (or at least keep your ears and eyes open), as you might learn a few teaching techniques that will transfer to your homeschooling endeavors.
And remember–fun learning is forever learning!
