1. 16. Making Room for Complexity in Group Collaborations: The Roles of Scaffolding and Facilitation

   Författare :Pia Andersson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; action research; adult development; awareness; coaction; collective efficacy; complexity; group facilitation; hope; metacognition; methods for complex issues; scaffolding;

   Sammanfattning : This thesis has a dual objective: the theoretical aim is to analyse how developmental scaffolding influences the way that group participants’ conceptions about societal issues of concern, appropriate goals and courses of action change as their awareness of the interconnectedness between different issues, conditions, causes and consequences increase. On a practical level, the thesis aims to contribute insights into the craft and role of facilitation for facilitators, project leaders, dialogue designers and other practitioners whose engagement in group processes involves scaffolding the understanding of issues that have a considerable degree of complexity.
