Using Bibliometric and Social Media Analyses to Explore the "Echo Chamber" Hypothesis

Educational policy debates are no longer occurring exclusively in academic or governmental settings. Intermediary actors are promoting research using a variety of traditional and non-traditional media to advance and oppose policy agendas. Given the current policy arena, it is useful to re-examine the research underlying current reforms, and to determine whether there is an "echo-chamber" effect, where a small, or unrepresentative, sample of studies is repeatedly cited to create momentum around a policy proposal. In exploring the echo-chamber hypothesis, we focus on two distinct methodologies. Using bibliometric methods and examining social media activity by intermediary organizations, our preliminary evidence suggests the presence of an echo-chamber effect in policy debates.
