The document discusses applying ecological principles from natural science to social science, specifically in the contexts of adult education services and online professional networks. It introduces the communicative ecology approach and network approach as methods for analyzing these systems as ecosystems. The goals are to understand how knowledge is accumulated, transformed, and flows through the systems by mapping the networks of actors, ties, and communicative actions between actors. Case studies will examine how vulnerability characteristics may restrict access to adult education opportunities, and analyze content sharing and turn-taking in online professional network threads. Workshop activities will involve collecting and mapping data on these systems using communicative ecology and network analysis tools and frameworks.
