This paper reports on school-university collaboration during an action research project, which aimed to build a writing pedagogy for students with Learning Disabilities in the trilingual, biliterate educational context of Hong Kong. The project was established through interpersonal relationships built from the ground up between stakeholders from a university department and a secondary school. The informal social networks were the locus of innovation and creativity within the project. This paper examines four broad dimensions of collaboration: the relationships created, the resources shared, the action taken and the pedagogy created. We discuss these dimensions of collaboration from the perspectives of the stakeholders. We found that each stakeholder aligned their motivations and expectations with other stakeholders to achieve the common goals of the research and consequently we call such alignments of interests “research networks”. Finally, we suggest that “research networks” constitute an important, yet overlooked component of action research.
