A broad example of a hashtag used in education is "edchat", to communicate with other teachers and people using that hashtag. Once teachers find someone they want to talk to, they can either direct message the person or narrow down the hashtag to make the topic of the conversation more specific,w using hashtags for scichat (science), engchat (English), sschat (social studies).<ref name="Carrie-2015" /> In a 2011 study, researchers found that young peoples use of Twitter helped to improve relationships with teachers, encourage interactive learning, and ultimately lead to high grades.<ref name="Carrie-2015" /> In the same study, it was found that out of a group of 158 educators, 92% agreed that the reason they use Twitter is because of how user-friendly it is,<ref name="Carrie-2015" /> another 86% agreed that they started and continue using Twitter because of how easy it is to learn, and finally,<ref name="Carrie-2015" /> 93% said they use Twitter because it is free.
