As a former IB Primary Years Programme (PYP) teacher of many, many years who transitioned to librarian 2 years ago, I feel that the librarian is key in developing the core skills students need for inquiry. Teachers send students to the library with "burning questions" on an ad hoc basis or as part of Open Inquiry/Genius Hour initiatives. I also plan collaboratively on a regular basis with classroom and specialist teachers on how best to integrate explicitly taught information literacy skills, as well as research skills into their inquiries. I would say that this consititutes the largest portion of my role as good quality collaboration takes time. In my school we use models by Kath Murdoch and Kathy Short to underpin our inquiries, which fit very nicely with the FOSIL model.
