I think it's great that these teachers are taking initiative to make up for the system's deficiency (i.e. expensive textbooks targeted towards the biggest markets). However, I agree with this - I would hope that the goal would be enhancing learning, understanding, and appreciation of the subjects as opposed to passing the standardized tests. Granted, the two are not exclusive, but I think focusing on the first is more likely to lead to the second than the other way around.
