We don't have a Learning/Training Department at our school but I think what you suggest ("Make everone's job to share what they learn") is critical. In my experience, that takes a certain mindset from the side of the leaders because unless they encourage and eventually make it "mandatory" few people would share their learning experiences or resources. There is a sense of competition or, on the contrary, apathy that I would never understand about some people. On the other hand, "mandatory" tasks become unsustainable if people are forced into them. A good leader, however, would instill passion for learning and will create this synergy. Thank you for sharing these insights. Good read and food for reflection, too, as usual.
