This paper examines that discussion expand and cultivate knowledge structure around disaster mitigation. One of a problem about disaster education is that residents are hard to take action for disaster mitigation in spite of knowledge they have. We think a reason of it that resident's knowledge isolated each other and need to construct knowledge structure to do disaster mitigation action.
We did an experimentation to examine it. A test held on Facebook as Social Network Service (SNS) to solve a problem of disaster education which is physical limitations. An experimentation procedure is as follows. First, the subjects watch the animation about Tokyo earthquake and diagnosis the risk of their daily milieu on a web application which is supplied by experimenters. Second, they draw the predicted situation of Tokyo earthquake with reference to the animation and a web application. Finally, they share and discuss opinions about predicted situation of the Tokyo earthquake with others.
After a test, author analyzed it by four analyses, raw frequency analysis, content analysis with grounded theory approach, co-occurrence network analysis, collocation analysis. The analyzed result shows that knowledge structure around disaster mitigation of subjects expanded and cultivated through an experimentation.
The result shows that discussion around disaster mitigation through SNS has a possibility to expand and cultivate knowledge structure on disaster education.
