Iowa Science Teachers Journal
When I found a way of giving my students a better view of what goes on underground, they started asking better questions, and they found better ways of answering those questions.

Ethics As A Science: Going From "Is" To "Ought", Warren Shibles
Iowa Science Teachers Journal
Two beliefs which serve to prevent teaching, defining, or progress in ethics and morality are: 1. That we cannot derive an "ought" from an "is." We supposedly cannot derive value statements from factual statements. 2. That we cannot define ethical terms in terms of non-ethical terms (naturalistic fallacy).
