LOL. I like how you think, treecritter. That was always my classroom strategy, as well. Students have the best overall grasp on material that challenges them and forces them to
grow... but it isn't always a pleasant process for them.

Thank you for the text suggestion. I'll take a look at that.

Kai, thank you for weighing in here. It's good to know that someone else has used those resources with success, particularly with a gifted HS student.

<slaps forehead> MIT OpenCourses... DOH!
That's a bookmark already on my desktop, in fact. I just didn't really think to look there, since I assumed that most of it would require math that DD hasn't yet taken. Thanks so much for reminding me!

Yes, I know that DD needs to take probably 2-4 years of mathematics BEYOND Calculus if her interest in astrophysics is a serious one.

She's definitely not afraid of the math, and it comes pretty easy to her; so she's going to get there eventually. But she is still a couple of years away from calculus.
A survey course like this is more about feeding her current interests enough to keep her engaged in activities that the school thinks are important (and that she thinks are repetitive, dull, and useless)... like studying for state-mandated testing... learning about the rock cycle-- again, I mean. LOL.
