This guideline comprises a set of arguments in support of Inquiry‐based Science Teaching, supported by a number of references, apposite quotes and exploratory small‐scale research. The intention is that the guideline will serve as a realistic pedagogy for beginning teachers of science in courses of Initial Teacher Education that, with some experience of teaching and support from tutors at school and university, it can help them to develop a disposition that favours opportunities for pupils to engage in inquiry in one way or another. The text of the guideline will also form the basis of a website that will have a range of links to, for example, video examples of inquiry in action, published papers from research, policy and practice and other sources of advice and ideas
