Text best for large amounts of content (search, produce) Conclusion: Use text. Next question: How to display text on mobile phones?
Technology dating back to 1972, film, 16 wps Used for speed reading, dyslecticts
Show demo
Slow scroll most similar to ordinary reading on phones. Fast RSVP most different. 8 of 10 prefer slow scroll over fast RSVP. 0 of 10 prefer fast RSVP over slow scroll.
1 of 10 perform better with slow scroll over fast RSVP. 6 of 10 perform better with fast RSVP over slow scroll
Very fast because no eye-movements are required. “ Forces” user to be focused.
If there is time: Alternative technique is Leading/times square
If a teacher can write in a blog he can also publish content to web/mobile/RSVP Could use wap-push

Today
Overview of mLearning (mobile learning) in general
Demonstrations and overview of some research I have done at KTH on mobile learning.
Ideas on how to use mLearning in your courses today.
The role of mLearning in the future?
What is mlearning?
Many different perspectives (from “Big issues…”)
Technocentric – Learning using mobile devices
Extension to eLearning – “Does not help in characterising the unique nature of mobile learning”
Augmenting formal education
Learner-centred – leading to the definition…
What is mlearning (2)?
"Any sort of learning that happens when the learner is not at a fixed, predetermined location, or learning that happens when the learner takes advantage of learning opportunities offered by mobile technologies" (O'Malley et al 2003, and Wikipedia)
Except for the word ”technology” a book would fit well into the definition.
More recent: “The focus of their work is on mobile learning as communication in context (Sharples, 2005)”.
A broader definition could also include support functions that makes life as a student easier.
Why learning with “portable technology”?
Some arguments
Study when you want - cf learning styles, mobile TV
Study where you want - can be used everywhere, doesn’t require a table, electricity, can be used in bed…
Ownership - “everyone” owns a mobile phone
Always ”on” - no startup time required
Discreet - socially acceptable to do things with mobile phone in public environments
Battery life - lasts for days
The above applies to books as well, but a few factors are unique to mobile phones
Ubiquity - everyone always carries their mobile phones
Features and convergence - increasingly more features: video and audio playback, high-speed internet connection, high resolution displays, positioning…
Content availability - don’t have to carry an entire library - all of the internet is available.
Searching capabilities
Communication
Still: mlearning will not be attractive to all, but some students
What should mobile (higher) educational activities focus on?
Providing content and activities for learning anywhere, anytime.
Not necessarily learning everything everywhere, but at least something meaningful when you want to.
Learning in context
To improve the “Learning infrastructure” using mobile technology.
Simple to use, and low cost for university, teachers and students.
Usable in all regular university courses = use mobile phones and possibly low-tech.
Examples of my day. A morning at the metro (1)
Organize my day
Read email, mark important letters
Look over my calendar and my to-do-list and possibly make preparations.
Get updated on what’s new
Twitter, mark important tweets
RSS feeds from blogs, mark important entries
Possibly “retweet” relevant information
Review my notes
Evernote
Google docs
Examples of my day. A morning at the metro (2)
Occasionally
See a TED Talks video
Watch/listen to a podcast
Practice Finnish vocables / Flashcards
Read an ebook
Context based
Look up the Finnish translation of something
Look up something in Wikipedia
Project 1: MUSIS
Push media files to mobile phones
Students subscribe to different channels
Each channel can be used to send text, audio and video messages.
Examples of channels:
Fun (mostly video)
Lunch menus (text)
Course channels (text, video)
One minute tech tip (audio)
Both scheduled messages and on-demand messages can be sent
Message scheduling
Instant message sending
Client interface
Messages downloaded in background, without user interaction.
Notification beep when message successfully downloaded.
Different icons for different channels (not for different media formats)
Click on message to display or play it in phone’s external applications
Video messages
500KB limit
3GPP/MPEG4
Sample video messages
Funny video clips (fun channel)
Course information (course channel)
Students felt a bit embarrassed when watching video in public environments
Not popular, but content used were of low quality.
Audio messages
Sample audio channels
Music
Daily idiom (education)
One minute tech tip (education)
Difficult to hear in noisy environments
Headset required.
Only appreciated when audio gave added value, like language courses
Text messages
Sample text messages
Lecture introductions
Reminders and notifications
Lecture summaries
Lecture preparations like literature to read, assignments to do, problems to consider
Instant feedback forms included
Classroom response system
Average level of interest in course related (text) messages
Services suggested by students (42 suggestions, 6 education related) Service Average grade Message when some information is available, like exam results 5.0 Updated course schedules after changes 5.0 Examples of exam questions with answers 4.9 Tomorrow’s schedule 4.9 Tomorrow’s activities in a course 4.8 Project deadlines 4.8 Average grade for course related services 4.92 Average grade for for other services 2.95
Main results, first phase
Push messages to phones better than email due to instant notification. No delay and no computer needed.
Low cost important.
Persistent storage of messages on a web portal wanted.
Text preferred by 92% over audio and video. Good for skimming information.
Maximum 1000 - 2000 character long text messages.
Audio and video difficult to hear in noisy environments, not high enough quality, embarrassing in public environments, headsets required and no extra added value for education.
Simple user interface. 1-click preferred.
Project 2: SMS + XHTML Mobile
Make a similar system usable in all courses today.
Only text messages.
Works on “all phones”
Most appreciated media format according to results from phase one
Only use simple standard technology (php, apache, sms, blogs)
Learning goals for phase two
Students should be able to prepare for lectures using “Advance organizers”
“ Introductions” to lectures
Gives a basic cognitive framework with which to relate the learning content of the lecture.
Ought to be ideal to read on the way to the university
Revise material - important for learning
Available anywhere, anytime
Spaced repetition important for learning.
Review questions/sample exam questions - activates students
“ Lecture packages” to fulfill these goals
Lecture package - message and index
Message with clickable link sent when new material is
Leads to Index page for all messages sent in a course.
Also available for viewing with a desktop browser via a blog.
Lecture package - message and index
Message with clickable link sent when new material is
Leads to Index page for all messages sent in a course.
Also available for viewing with a desktop browser via a blog.
Appreciated and used, but mainly from desktop computers (90%)
Summaries/introductions of lectures was most popular
Project 3: Providing text based content on mobile phones
Background on text based content
Easy to produce. Much content already available.
Low bandwidth requirements (around 150 KB for a compressed 300 page book).
Random access to any part of the material.
Browsing/skimming/searching is easy.
Preferred over audio and/or video by 91% of the students in an earlier mLearning study.
BUT - difficult to read longer texts on small screens.
Solution: RSVP
Rapid Serial Visual Presentation
Display one word at a time in a rapid sequence.
Can increase reading speed dramatically for trained users, with high level of comprehension.
Demo
http://www.hedin.mobi/dsonline-demo/
Prototype: Feedo RSVP
Only requires phone with Java MIDP 1.0 -> usable on almost all new phones.
Can read RSS feeds -> easy for teachers to produce and publish content.
Perceived level of comfort for using the different methods (scale 1-7: Higher number->more comfortable)
Percentage of correct answers using the different methods
Positive aspects of RSVP
Very fast, up to 3 times faster for some users.
User must be focused.
No negative consequences for the limited display size on a phone -> good for mobile phones.
Good for skimming texts.
Negative aspects of RSVP
No spatial memory possible (“I read this far up on the right of a page”).
Less “random access” than with spatially presented text. Difficult to navigate in the text.
Difficult to handle pictures, formulas, tables etc.
Difficult to highlight, make notes etc. in the text.
Users not used to the technique (compared to 15+ years of experience with reading spatially presented text daily)
High cognitive load.
Teacher perspective: Publishing content
Publishing content by any kind of Content Management System (or blog) capable of generating RSS-feeds.
Parallel publishing (web, mobile web, RSS-reader, RSS-RSVP-reader)
Any text-based content.
Notify students of new content by SMS
Project 4: Lecture casting with enhanced podcasts
Enhanced podcasts - podcasts with graphics, audio and synchronized chapters.
Easily produced from a PowerPoint presentation (with suitable software)
Used in two courses with a total of 75 students to pre-record lectures (and then again this year in three courses).
Desktop view with iTunes - Demo
Online on slideshare http://www.slideshare.net/bjornh/slideshows
3gp on mobile - small
3gp on mobile - full screen
Selected results - mobility
I would be very interested in watching lecture podcasts on an iPod/mobile phone on 'waste time', like when waiting for a commuter train, traveling on a train or bus etc (given that I owned suitable equipment)
Selected results - usefulness
I believe the podcasts were very useful.
Selected results - compared to lectures
As a whole I prefer enhanced podcasts over regular lectures.
Selected results - review lecture content
To be able to go back to parts of the lectures you didn’t understand is very important.
Selected results - navigation
To be able to go back and forth and ”jump” between chapters in a podcast is very important.
Selected results - time- and place shifting
The possibility to access a lecture podcast without having to be at a specific place at a specifict time (like a lecture) is very important.
A quote on podcasts in general
"Podcasts have big advantages when you work in parallel in several projects, and therefore have to skip some lectures. Podcasts covers something I believe is missing in several other courses; to be able to go back and review lecture content afterwards. Often you are not quite ready to absorb all the knowledge at a lecture with unknown content, therefore it is great that you can watch the content twice. Furthermore you can pause and complement with literature for a deeper understanding, everything in the peace and quiet of home, with a cup of coffee at hand, which is very rewarding for a student under pressure."
podcasts in iPods
5 students owned suitable iPods
3 stronglyagreed" with the statement "I believe it was very useful to see podcasts in my iPod", and 2 agreed to the same statement.
Of these five users, all used the podcast on waste time, like when travelling by bus or train.
Three students also used them at home, two of which watched them in bed before going to sleep.
On the question about what advantages they saw with watching podcasts on an iPod instead of a desktop computer, the mobility was as expected considered very important. One student said it "… could be quite tiring concentrating by a computer without doing other things at the same time" and one believed it was less tiring watching an podcast on an iPod for a long time, than watching the same podcast on a desktop computer.
Podcasting summary
Students appreciate the increased freedom.
Good to be able to review lectures later.
Mobility aspects are appreciated.
Navigation within lecture important.
BUT
Not suitable to all kinds of teaching styles
Decreased interaction
IMPLICATIONS
Usable in many/most courses with little extra effort.
Good tool for Open Educational Resources (OER)
Allows universities to share content and courses.
Recent projects
Spaced Repetition
Good for memorizing (like language learning, terms, anatomy, flora/fauna etc)
Current desktop implementations. Extend to mobile and web domains.
Location-based learning reminders
Application where students can ”tag” locations (KTH, Home, Metro, Odenplan …) and register reminders to study when arriving/departing to such places.
Inluced application to study chemistry on mobile phones
Low drain on battery (since non-GPS-based positioning)
Not very accurate
Appreciated by students, especially to find new opportunities to study on ”waste time”
Issues to discuss from ”Big Issues..”
To be “innovative” mLearning applications “Should be transformative in nature, i.e. allow learners to achieve things they couldn’t have achieved before.”
Learning in developing countries. http://www.nokia.co.in/A41427317
“ Technology can provide us with so much assistance that we forget how to do things ourselves”.
“ We have to be careful to design learning experiences with technology that enhance learning, rather than simply making it easier for people to do something”.
“ A key issue [in an application] is that its use is optional – it is possible to undertake the same learning objectives without it – and it is ideal if students desire it, rather than it being forced on them”
Issues to discuss from ”Big Issues..”
Motivating/affecting factors
Control over goals
Ownership/appropriation
“ She defines appropriation as the integration of a new technology into the user’s activities.
Her analysis revealed a two way process in which the user adapts the tools they use according to their every day practice, prior expectations and preferences in order to carry out their activities and how, in turn the tools also change the user’s activities.
Fun
Communication
Learning-in-context
Continuity between contexts
When to relax? Increasing bad conscience for not studying?
Issues to discuss from ”Big Issues..”
How to handle conficts between personal informal learning and traditional classroom education
“ Children in general do not want school to intrude on their personal life. There is a danger that the enthusiasm of schools, and some parents to extend school by, for example, parent access to school intranets, bite-sized teaching and revision via SMS, and new technologies such as location-based tracking, may be seen by children as schools attempting to colonise and control their social world”
Issues to discuss from ”Big Issues..”
“ One of the main assumptions we considered … was the fact that in the coming 10 years, whether educators want it or not, more and more students will bring computing devices (with wireless communication) into the classrooms”.
Issues to discuss from ”Big Issues..”
“ On the pedagogical level, the idea of mobile learning is often associated with informal learning settings which could be triggered by situational affordances or could just take place whenever and wherever the learners want to. It is an issue as to whether this kind of learning yields the necessary degree of systematisation and coherence (or maybe these factors are over-estimated, based on existing justifications of institutionalised learning?).
“ Do we have a problem with fragmented experience and fragmented learning activities in technology enhanced learning? If yes, is the fragmentation problem a particular challenge for mobile learning scenarios? Do we have pedagogical strategies for de-fragmentation which could be supported by adequate technologies?”
Discussion?
What do you think?
Can mlearning be usable in
Campus courses?
Distance courses?
Informal learning?
In the unlikely event of spare time: Accessing web 1.0 on mobile phones
Web sites often not adapted for mobile phones.
Small displays
Complex navigation
Unnecessarily large files (pictures)
Long download
Plugins sometimes needed
Approach 1: Do nothing
Almost impossible to view page.
Much unnecessary content (kth.se=184kB roughly equalling 3 SEK to download)
Approach 2: Use mobile CSS
A bit easier to view and navigate.
However, same amount of unnecessary content still downloaded
Approach 3: Use some technology and templates on server
Easy to navigate.
No unnecessary content.
However, not usable for pages in general.
Approach 4: Use web proxy to adapt content
www.skweezer.net
Easier to view and navigate than approach 1 and 2, but more difficult than approach 3.
No unnecessary content.
Usable on all web sites.
Approach 5: Use special web browser (opera mini)
Roughly equal to proxy service, but generally looks better
Also makes clever, but not always good, guesses about content.
No unnecessary content.
Usable on all web sites.
Usable on most modern phones.
Access content: Dropbox
Share synchronized folders between several computers.
Iphone support to view files
Access content: Evernote
Store documents, text, voice and images
Native iPhone client, relatively good web clients for Android (read only)
