I have the privilege of working in a community which encourages innovation amongst our teaching colleagues. Every year a fellowship opportunity is funded for Manaiakalani teachers to apply for. The Manaiakalani Innovative Teachers receive 12 days of paid leave throughout the year to focus on a teaching as inquiry project they have developed in their own classes. They come together once a term for a professional learning group and to have their inquiries challenged by their peers. The MIT teachers this year range from teaching 5 year olds to 18 year olds.
These teachers all follow the same "Learn Create Share" framework that our young learners use. So you can follow their progress as they share publicly online.
I recommend checking out the 2013 cohort at this link. They have shared their inquiries publicly and at the end of the year each made a very short video reflecting on the outcomes of their inquiries.
