It is really hard to tell. Reading his "Teaching Philosophy" page is kind of revealing to his thinking on education and religion. Here's an excerp:
Undertaking a college education is not without risks. These can be as superficial as wasting time and money on a worthless course, or as enormous as losing ones entire value system. Just because one pays tuition, one is not guaranteed success or happiness. Nor is one guaranteed that his/her most cherished beliefs will go unchallenged. Indeed, many students find it difficult to communicate with friends and family after completing a college education because they no longer share the same beliefs and values. College has introduced them to new knowledge and new ways of thinking. For many, especially those raised by parents who were not college-educated, college is a time of "de-acculturation," wherein one gives up the culture in which one was raised, and subsequent "re-acculturation" wherein one takes on a new culture. My hope for all of my students is that they will become acculturated in "the life of the mind." This means that they will take responsibility for the quality of their education and for the quality of their thinking. They will base their actions on what they know to be true, rather than on what they wish to be true. They will see learning as its own end, not done for the purpose of passing a test or getting a good grade or getting into a particular career. They will dedicate themselves to their own lifelong education.
He really puts down uneducated people throughout the page which is more typical of an atheist liberal elitists than a devote Christian, and seems to think it is a good thing that students lose their value system, which I would take as their religious upbringing. I may be reading things into what he says, but I wouldn't want this guy teaching my child. Then again I am not the one who determines whether this guy is a good Christian or not.
I have known several people who became "intellectual agnostics" as a result of their public education. There is a tendency to believe everything a teacher says. After getting out in the real world, getting "mugged" by responsibilities and finding out that the teachers, like the parents, really didn't know everything after all - some want answers.
Those are the ones that move from being spectators to being players and actually engage in the research and debate. The "intellectual agnostics" I've known who became players, are now Christian.
