Linking online identities and content in connectivist MOOCs across multiple social media platforms

WWW 2016, April 11-15, 2016, Montréal, Québec, Canada.
Paper: http://www2016.net/proceedings/companion/p483.pdf

In this paper, we examine how multiple social media platforms are being used for formal and informal learning by examining data from two connectivist MOOCs (or cMOOCs). Our overarching goal is to develop and evaluate methods for learning analytics to detect and study collaborative learning processes. For this paper, we focus on how to link multiple online identities of learners and their contributions across several social media platforms in order to study their learning behaviours in open online environments. Many challenges were found in collection, processing, and analyzing the data; results are presented here to provide others with insight into such issues for examining data across multiple open media platforms.

Linking online identities and content in connectivist MOOCs across multiple social media platforms

  4. 4. Introduction Project on Learning Analytics in the Social Media Age (#pLASMA)  To determine and evaluate measures that can help educators manage their use of social media for teaching and learning through the use of automated analysis of social media texts and networks pLASMA is supported by funding from the Social Science and Humanities Research Council. 5

Social Media Use for Teaching 163 8 9 14 11 30 63 61 69 57 19 68 56 25 52 53 62 75 90 94 98 123 131 132 146 157 157 179 0 50 100 150 200 Asynchronous discussion Virtual worlds Academic bookmarking Social bookmarking Academic social networking Presentation sharing Central course blog Wikis Student individual blogs Synchronous discussion Microblogging Multimedia repositories Document sharing Social networking Outside the LMS Inside the LMS • Our recent survey showed a wide use of social media. • Instructors overwhelmingly find and use media from outside their institutional learning management system • The greater use of non- institutional platforms increases the difficulty of determining the full extent of learners’ media- based contributions. 6
  6. 6.  Contemporary learners can leverage multiple media platforms  to create and sustain social relationships and discover, share, and co-construct knowledge 1. Determine  whether and what types of learning occur on different social media platforms and  how learners choose what platform to use and for what purposes 2. Develop and evaluate methods for learning analytics Objectives 7
  7. 7. What can a network tell us from an instructor and student’s perspective? 8 Example: #CCK11 Class Communication Network on Twitter
  8. 8. Today’s focus  What are the challenges associated with the collection and processing of social media data across multiple platforms in the context of learning (both formal and informal)? 9

  16. 16. #pLASMA MOOCs Data: Challenges  Some posts contain mostly images, videos or are live seminars, no text to be extracted  Unreachable links, e.g. expired blog links  Some domains have disappeared or now require a login password  Participant comments are partly on the MOOC site, partly on blog pages hosted elsewhere  Some posts are not in English @gruzdpLASMA.socialmedialab.ca 18
  17. 17. #pLASMA MOOCs Data: Identity resolution Coreference resolution • Resolve single identities across multiple platforms • E.g., @gruzd vs anatoliygruzd Alias resolution • Identify two or more people with the same name or alias across platforms • E.g., Dave and David Challenge • Some accounts are anonymous => not enough information to match users automatically @gruzdpLASMA.socialmedialab.ca 19

  19. 19. Results Number of unique users who posted on each platform pLASMA.socialmedialab.ca @gruzd 21 • Twitter and Blogs were the most popular platforms • Why is there a significant difference in the number of users on Twitter vs Blogs in #Change11 and not in #CCK11? 27 56 17 18 0 100 200 300 400 500 600 700 800 900 #Change11 #CCK11 Twitter users Blog users Blog commenters Discussion posters

  23. 23. Conclusion  Although we expected that we would need to identify and resolve online identities across multiple platforms; but in reality, both classes primarily relied only on Twitter for user-to-user interaction.  And when users posted to both Twitter and Blogs, ~74% of them used the same username pLASMA.socialmedialab.ca @gruzd 25
