title: Teachers' perceptions of Twitter for professional development.
abstract: OBJECTIVE
  The aim of this study was to determine how school teachers in the United States (US) perceived using Twitter as a means for professional development, engagement in communities of practice, and any benefits or drawbacks to participating in Twitter.
  
  
  METHODS
  This qualitative research utilized an embedded case design with three sources of data: (a) three consecutive months of tweet data from late 2011 archived on the host website, relating to #EdChat, a weekly online chat in Twitter about education issues; (b) interviews with 19 school teachers in the US who participated in the #EdChat online discussions in Twitter; and (c) Twitter bio and Tweet data of the 19 teachers interviewed. All data were entered into NVIVO (QSR International Pty. Ltd., Doncaster, Australia) for content thematic coding, and The Communities of Practice and Connectivist Conceptual Framework was used to inform this analysis. The researchers' interpretations were verified with participants, and data triangulated across all sources to strengthen confidence in the results.
  
  
  RESULTS
  Five main themes and 17 subthemes emerged from the data across all sources. The main themes were teachers' perceptions of sharing knowledge and resources, Twitter promoting a sense of belonging, Twitter providing meaningful professional development, and teachers' views on the technical benefits and drawbacks of using Twitter.
  
  
  CONCLUSIONS
  Regardless of years teaching, subject area, or age, educators perceived Twitter as providing an online forum to reflect upon practice, exchange knowledge and experience, and be in the presence of supportive colleagues. While participants experienced the pace and volume of information as being overwhelming at times, educators developed skills to managing this and perceived discussions to be learner-centered and supportive. Teachers valued the sense of community and learning that they reported were not otherwise available in their own physical workplace. Overall, participants perceived that the benefits of participation in online Twitter chats for learning outweighed any drawbacks experienced. This article includes implications for future research and how social network sites may be used as a supportive venue for educators, therapists, and students, including individuals with disabilities.
