An interesting site with resources – in e-book form – that’s just what it says:

As literature professors, we feel strongly that in the teaching of literature a disservice has been done to our youth who have not been exposed to the great biblical and classical narratives. Sadly, many of our schools are much worse than Lewis’ ‘Experiment House.’ Lewis himself asks ‘what do they teach them at these schools,’ a sentiment we parents and educators often echo. Lewis offers a remedy; indeed through his Chronicles of Narnia, readers of all ages learn of the virtues of heroism, humility, obedience and sacrifice. We meet in the figure of Aslan, a Christ figure, a sacrificial lamb, and through the adventures of the children, we recognize how Christian doctrine influences all our actions. Here we delight in the triumphant quests of Lewis’ heroes and heroines, the little ones who teach us how to do battle against the evils of our world. And so, as creators of this website, we have taken Aslan’s ‘warning’ to heart and present to you, dear reader, analyses and lesson plans so that you may bring Lewis’ message to your own little heroes and heroines.
