I have an assistant principal based in a local school keen to undertake an action research case study of the effectiveness of a newly launched professional learning community in his school as it seeks to implement some collaborative interventions to support students' learning, within a structure of shared/distributed leadership. I've made some suggestions of things that he could usefully be reading for his literature review, but I would appreciate the assistance of peers in identifying recent projects/articles that he might find useful to consult. Thanks in advance!
