	abstract = {Twitter can contribute the continuous professional development of teachers. Social capital theory can aid in the analysis of communication processes on Twitter.

The present study addresses this shortcoming by analysing a hashtag conversation among German speaking teachers. Using bibliometrics and semantic network analysis, we are able to show the relevance of the cognitive dimension of social captial.  },
