#OER COMMUNITIES: ANALYSIS OF THEIR TRACES ON TWITTER

This article aims at identifying the interaction dynamics of Open Educational Resources (OER) global communities on Twitter, from 2012 to 2017. Our purpose is to identify, by using Analysis of Social Networks (SCOTT, 2012; RECUERO, 2014), the best positioned nodes that serve as bridges for information exchange among central and peripheral OER communities within the network. Three graphs based on metrics of betweenness centrality, indegree and outdegree centrality are produced. The results show that five bridges and seven large communities prevail in interactions within the network. The five bridges are fundamental in maintaining the flow of information that emanates from the seven communities to more peripheral regions of the OER circuit. Six communities and four bridges are located in Global North and one community and one bridge are based in the Global South.
