Apparently people in Higher Education don’t use Twitter much.
In a report published in the March 2014 issue of British Journal of Educational Technology, Christine Greenhow, an assistant professor in the College of Education, and Benjamin Gleason, a doctoral student of education, examined the use of popular social media services by academics and found their practices lacking. In a survey of 1,600 researchers, they reported that 15 percent of respondents use Twitter for professional purposes, 28 percent use YouTube and 39 percent use Facebook. The way those services are primarily used is to find collaborators and disseminate scholarly work or the work of others. It’s not to reach out to students for the purposes of instruction.
One study like this doesn’t completely convince me it is true but let’s think about if it makes sense. If we assume it’s true there are two possible reasons for this.
1. Some professors have been professors for many years and are very set in their ways. Why should they Tweet?
2. Twitter and other social media is a two way street. Quite frankly, a lot of professors aren’t used to being questioned by their students. Twitter is a non hierarchical system. Your Ph.D doesn’t amount to much online.
I think the numbers will gradually change as older faculty retire and their place is taken by people who grew up with social media. We will see.
