Twemes, Connecting the remote network to a given event, Creates a collaborative resource based on unpremeditated story-telling.
Subjects: PhD students and researchers
Goal: to support collaboration among PhD students working in the disparate ends of expertise
Used Wordle to create "tweet clouds" to visualize the terms used
Tweet content directly corresponded to content of the lectures held that day.
Liked twitter for 3 reasons, easy and intuitive interface, tweets are shorter than blog posts, twemes aggregates content using the special hashtag
88% participated (60 of 68), 45% female, 55% male
No differences in responses concerning gender or educational background.
Only 10 (16%) had twitter accounts prior to the experiment
Most wanted to take active part in twittering. Were curious and intrigued.
70% found twitter encouraging to join discussions
55% continued to use Twitter after the experiment
Effective immediate communication
Complaints, Fail Whale, 140 character limit, Some found it distracting, Overwhelmed by the number of messages
no ubiquitous learning strategy
Microblogging can be used as an interesting discussion and sharing back-channel in learning events.
Signup and participation are influenced by peer users
Measures number of exchanges between 2 people
the geodisc distance /proximity between 2 people
minimum number of cut-points necessary to disconnect 2 people
40 students divided into 4 groups, 3 achieved the simulation
Simuligne - distance french learning session
Discussion forum: 2686 messages (45.11% of communications)
Email: 4062 messages (42.84%)
Chat: 12%, less successful because of the time constraints. people in DL (distance learning) like relaxed constrains
Asynchronous communications tools are best for DL

The usefulness of different tools in support of learning depends on which learning activities the tools should support.
blogs reach their full potential when it is related to other blogs, subscribed to, gets commented on
social bookmarking - most useful when done by a large number of people. recommendations based on your bookmarks subscribing to RSS feeds for new bookmarks
students' self-governed and problem-solving activities are the focal point of a learning process
learning environment needs to be open-ended because students' activities cannot be pre-determined
self-governed and problem-based activities are not very well supported by LMS. that's not their purpose
collaborative (working on the same project)
sharing context (students and teachers in the same class or school)
sharing a field of interest (may involve non-students and non-teachers)
will help evolve microblogging and improve the client and infrastructure of the software
requires looking at content and link structure
Used Twitter API to fetch social network of all users (how users are connected to each other)
total of 1,348,543 updates from 76,177 users
updates were fetched every 30 seconds
mapped each user to their geographic location from the profile
estimate growth of twitter based on how many users sign up each day, although the rate of users joining twitter has slowed, the number of posts are increasing, doubling every month
Twitter social network statistics match blogosphere statistics
there are more intracontinental links than across continents. this is consistent with observations that probability of friendship between two users is inversely proportionate to their geographic proximity.
hub/authority detection, friendship-wise relationship, information seeking, information sharing
