The document discusses how Twitter is being used by Australian engineering academic units. It finds that Twitter is being used for social media in engineering education to link students and practicing engineers, engage large classes in real time, and for student group communications when learning management systems prove unwieldy. It provides statistics on tweets, mentions, followers, etc. for 8 academic units and finds two principal patterns of Twitter activity: sending mostly undirected tweets and a more diverse model with various tweet types and more overall activity. The document concludes that Twitter is only one platform and network visualization is a useful method for evaluating social media use in engineering education.
