I think this is a "teach the controversy" advocate. This allows the subject of religion to be brought up in public schools in formal setting.
In a similar manner flying saucer advocates could "teach the controversy" about UFO artifacts tested and found to be apparently of earthly origin, etc.
It's just a scheme.
Teach the Controversy: Not really. The point is that science teachers should not be afraid to face controversy, if and when it occurs. Big mistakes were made dating the shroud. Should we refuse to explore that because this piece of cloth is also a relic? Avoiding controversy is not the solution to avoiding the teaching of controversy.
This Alaska teacher was either dogmatic in his skepticism or fearful or both. That is not science. That is not teaching.
