Teachers do need to establish ground rules about discussion: students should learn to listen politely to each other, and to agree to differ on occasion. Teachers can model calm and polite behavior, without giving in to irrationality. It is important to make clear to children the nature of evidence, what counts as evidence, and how evidence helps us to understand nature. It is equally important not to be contemptuous or dismissive of deeply held beliefs. It is important that students understand what scientific method is and how it differs from taking authority as one’s source of knowledge.
In Science lessons, it is important to be clear and confident about what is “controversial” among scientists and what is not. For example, the fact that life on Earth evolved is not controversial amongst biologists, though they may differ about time scales, the origins of life and the processes driving change.
In Science lessons it is reasonable to ask for reasons and evidence for any hypothesis put forward, and to differentiate between strong and weak evidence.
