The Consistency Theory All that one knows of reality are the sensory and mental reactions to it. Reality itself is forever beyond direct knowing. Truth, therefore, is found in the consistency of our constructs of reality. In knowing the world, each beginner builds his or her own, seeking for as much consistency as he or she can find between his or her own ideas and those of others. The Pragmatic Theory Knowledge is successful adaptation to the environment.
Truth is what works and learning is verifying.
Knowledge is the outcome of this process, but it appears in the curriculum principally as data for more inquiry. Christianity is based upon the gospel story that is found in the Bible. Other history books seem to suggest he did. The curriculum you teach must be the truth.
