Leading as boundary crossing: How teacher leaders lead across a professional learning network in Shanghai China

This paper explores how teacher leaders enact leadership practice across a regional learning network, Master Teacher Studios, an officially initiated teacher learning program in Shanghai. It investigates the leadership strategies that are employed for cross-boundary endeavors in the network. The concepts of boundary and boundary crossing, as expounded by Wenger and others, are used to guide an examination of the process of teacher leadership enactment across a network, which is elucidated as interpreting the boundaries, selecting/designing boundary objects, and participating in communities of practice. The paper fosters an understanding of teacher leadership practice as boundary work in a network context, and delineates a process of teacher leadership enactment, as well as the importance of teacher leader identity in the process.
