• 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

Study 1 (2007)Is microblogging a possibility for a specific community to exchange ideas, interests and

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“


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?

„in the background we discussed things more

deeply than the guys on the stage“

„Twitter can be distracting - you pay less attention“

before

during

after

Twitter stream at conference (ED - Media 08)


Results:

• About 150 participants (keynote)• 54 tweets / 74 minutes (before/during/after)• 4 categories of tweets: - Citations - Discussion - Hyperlinks - Comments


BUT:

• Only 10 active users wrote more than 5 tweets• 2 users wrote more than 50% of all tweets


Similar: ED-Media 2010

Two users accounted24% of all tweets



• 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


Positive results:

• Anonymous Feedback• Device Independent• quick and easy


BUT:

• 33 microblogs in 45 minutes - no real content• hard to follow for teachers



• 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?


16 students 4 MB per week

10 weeks


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)


BUT:

• Information Overflow• Only for people with same interests• „maybe“ useful for virtual announcements• students underestimated the work load• continious attention is needed



• 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?


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



• 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

Objectives for the Usageof Microblogging in HEI

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)
