The other half is to enable people to use those facts and techniques. That's why you get assignments, do presentations, etc.
Nominally. The real purpose of assignments, homework, presentations, etc. is for teachers to put on the apperance of adopting "new" techniques in the classroom, and to assign homework so complicated that parental assistance is a must as a diagnostic to see which child's parents aren't involved in their schooling.
Critical thinking is a skill you have to develop on your own. It's fundamentally incompatible with the teacher/classroom paradigm. The authority cannot instruct you to disregard authority and think for yourself; it's something you learn only when you're betrayed by your authorities.
The takeaway isn't "ID is wrong"; it's the methodology for applying the biological information they learned in class. It's also learning what is science and what is not, and what the purpose is of doing science. Those are all huge, huge lessons.
And too large for a high school science classroom. As we see here on the board every day, it takes a sophisticated understanding of evolution and molecular biology to even understand the arguments of ID, much less refute them.
For instance, a fact we regularly toss around here is that ID proponents conflate semantic meaning with Shannon information and try to apply the rules of one to conclusions about the other.
What the hell is that going to mean to a high school student? Claude Shannon wasn't exactly on the curriculum when I was 16. I was a pretty bright kid but I wasn't
that bright. My best friend was a math genius, he's gone on to Ph.D's in math and physics, but even
he wasn't talking about Shannon at age 16.
Adults barely have a handle on ID, including most of its lay proponents. It's not only outside the scope and purpose of a high school education, it's beyond the ability of the students.
