• A large percentage of Twitter accounts are inactive, with about 25% of accounts having no followers and about 40% of accounts having never sent a single Tweet
• About 80% of all Twitter users have tweeted fewer than ten times

With 75 million total accounts, an active user base of around 20% still leaves around 15 million highly active tweeters

Microblogging is a small-scale form of blogging, generally made up of short, succinct messages, used by both users and
business to share news, post status updates and carry on conversations Templeton, 2008

Higher Education occurs usually (not always) in overcrowdedlecture halls, students sitting under their laptops

information?

Overview Study 1
• Used Microblog application: Jaiku• Own Channel: „elearn“• Own FlickR account for pictures• Community: 23 German speaking EduBloggers (5 women / 18 men)• Duration: September - October 2007• Outcome: 240 posting, 201 comments

BUT:
• Small usergroup (23; 12 filled out evaluation forms)• just testing - 72% „I used it for the first time“• Outcomes? „not sure there is any potential“
Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
Recommendations for HEI
• some general pros• additional documentation effects • possibility to monitor students• no time constraints• mobile devices
• but no clear scenario for usage
Study 2 (2008)Can microblogging be used during scientific
conferences? Enhancement of live presentations?

Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
Results:
• About 150 participants (keynote)• 54 tweets / 74 minutes (before/during/after)• 4 categories of tweets: - Citations - Discussion - Hyperlinks - Comments
Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
BUT:
• Only 10 active users wrote more than 5 tweets• 2 users wrote more than 50% of all tweets
Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
Similar: ED-Media 2010
Two users accounted24% of all tweets
Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
Recommendations for HEI
• no continous microblogging on walls! (too much distraction for students and teachers, just a few make the noise)
Study 3 (2008)Interactive Lecturing by Integrating Mobile
Devices and Micro-blogging in Higher Education

Mass EducationInstant Feedback
Enhancement of lecture slides
Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
Positive results:
• Anonymous Feedback• Device Independent• quick and easy
Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
BUT:
• 33 microblogs in 45 minutes - no real content• hard to follow for teachers
Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
Recommendations for HEI
• timely limited interaction phases (open questions, feedback) are helpful and channel attention
• or: a moderator for microblogging
Study 4 (2008)Can Microblogs and Weblogs change
traditional scientific writing?

Positive results:
• Exchange of information• Useful for fast discussions• Help to share links and ideas

Differences between Microblogging and Blogging
• Blogging is reflective writing, short essays
• Microblogging is searching and sharing• more communication/interaction (replies)
Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
BUT:
• Information Overflow• Only for people with same interests• „maybe“ useful for virtual announcements• students underestimated the work load• continious attention is needed
Microblogging - Potentiala an der Hochschule Sandra Schaffert, Martin Ebner - Learntec 2010
Recommendations for HEI
• Microblogging seems to be usable for e.g. brainstorming and (fast)collections of links, pictures, videos• Usage for formative assessment: continious contributions, assessed by teachers• limited to fitting lecture topics (no fixed factual knowledge, eventually media related)
Study 5 (2009)Microblogs in Higher Education – A chance to facilitate
informal and process-oriented learning?
http://www.flickr.com/photos/billselak/2417001179
On average each student wrote 315 posts. Over a period of 70 days this resulted in around 4.5 posts each calendar
day. If the observation time is reduced by holidays (42 days) the number increases to 7.5 posts/each working day

Recommendations for HEI
• private talk is normal (about one third)• Microblogging is a COMMUNICATION tool, that includes private talk• if you want to support communication (or microblogging) the task should be open

Microblogging for Optimisation of HEI
• Fast interactive, colllaborative collections• documentation and accessibility of collections • quality assurance (monitoring, feedback)
Microblogging for Innovation of HEI
• tool for new assessment forms (formative assessment)• provides new (more) communication
possibilities (between teachers and students)
