@vikingkirken – I agree re. learning to read critically, identifying bias, etc. However, I have a goal of my children adopting a solidly Christian worldview while understanding other worldviews. In our current culture, I’ve no worries that my children will want for any non-Christian worldview materials as our culture is saturated with them. One must go out of their way to find materials presented from a Christian worldview.
@pjssully – another resource is Stossel in the Classroom, free online or by DVD. In fact, I am using these as the basis for a Thinking Citizens ms/hs co-op class next term.
ETA – Stossel is Libertarian in viewpoint.
