Summit Ministries as a couple of very good articles about teaching a Christian worldview (Part 1 and Part 2).
A quote that particularly struck me:
There simply is no substitute here for equipping students to dive deeply into the Scriptures. At the same time, however, it is important to help them dive into the Scriptures in the right way. Unfortunately, many students have only seen the Bible handled poorly by other Christians. Often, their only experience with the Scriptures include it being replaced by therapeutic clichés, utilized and memorized completely out of context, tacked on but not central to a lesson, strangely pieced together with other verses to make a point, proof-texted to supplement a devotional book or song lyric, or largely ignored.
