Group learning in participatory planning processes: An exploratory quasiexperimental analysis of local mitigation planning in Florida

Scholars have identified group learning as both an outcome of effective participatory planning processes and as the means to achieving agreement on planning outputs and to building constituencies for plan implementation. This article examines the challenges of designing empirical studies of group learning in participatory planning processes that have strong internal and external validity and reports the results of a quasiexperimental analysis of how different degrees of participation increase mutual understanding of planning problems and solutions.
