It is too labor-intensive. Yes, it does require much from the teacher. Everything in life that is worth anything has come about through struggle and toil and patience and diligence. You must internalize the principles in order to teach them. And that takes time. Too much time, it seems sometimes. But in the end the price is small compared to the rewards of seeing your children maturing in the Lord, reasoning effectively form God’s Word and exhibiting Christian character.
It is too expensive. Actually the Biblical Principle Approach is economical. Real literature and other resources can be reused and enjoyed. Compared to consumable programs, BPA is affordable.
It is only focused on American history. It is not. We study the whole Chain of Christianity, that is, the whole timeline. Nothing in His Story happens in a vacuum. Since we study from cause to effect, we study all of history all around the world.
It is classical education. BPA is not classical education after the Greek model. It is considered Biblical classical, after the Hebrew model.
I can pick it up and use it right away. While the Noah Plan from the Foundation for American Christian Education has lesson plans for grades K-3, but is difficult and burnout-inducing to jump in before you have renewed your mind and formed your philosophy of education and at least gotten the basics of a BPA education under your belt. It’s not a race or a canned curriculum. It is something that takes time and effort to implement.
