Introduction
Web pages that contain educational material are
normally just read passively
Normal books allow users to make comments in the
margin or highlight important parts for later use
Internet allows for sharing information with others
System to share annotations with others for web pages
useful?
Research question
Main question:
How can we design a system for sharing annotations on a
global scale that increases the utility and learning
benefit of e-learning material and how will users use
such a system?
Research question
Q1: What attributes are important for a functioning
annotation system to support and extend reading and
understating of electronic reading material?
Q2: How does shared annotations affect the reading and
involvement with the text?
Q3: How can annotations generate a richer structure for
web pages and how can this be utilized?
Background
Previous comments in books useful for new readers
(Marshall, 1997)
Many systems died out around 2001 with the dot-com
bubble
Web browsers and internet technologies are now more
robust than in 2001
«Web 2.0» systems are starting to show up that focus
on building annotation communities
Benefits from more users
Method
Found the features needed for a shared annotation
system by looking at previous contributions and
results
Implemented a prototype system to use for user testing
Qualitative evaluation of interview with users of the
prototype
Prototype
Called Dannotation
User loads system
with bookmark
Loads with a bookmarklet
Implemented with PHP, MySQL and
JavaScript
Allows users to make annotations on
any web page by marking text to
highlight
Shared with everyone that loads the
system on that page
Allows for links, tags and comments
Loads menu into
current page
Retrives annotations
from server
Posistions
annotations on page
Demonstration

User test setup
One group of 4 master in media technology students
to use prototype on Information retrival HTML book
Participants of the courses «Web design» and «Web
publishing» to use it on web resources like w3schools
Interview with the master students after exam in
«Databases in electronic publishing»
Supposed to send questionnaire to participants from
other courses, but not done yet. 4 students registered,
but only two made any annotations. Might be too few
Results
Six total users. Four made
annotations
Only one user outside the
instruction page
This user made 23 of 31 total
annotations
Most did not open any
annotations to see content
Results from interview
3 students interviewed, two used the system. The last
one had seen it in use
All of them agree that it could be a useful tool when
reading educational material
Usefull to find additional good resources
Helps to find important parts of the text
Improves distance learning, both between
teacher/student and student/ students.
Results from interview
Sees the use if there were more users
The user with most annotations didn’t find the
shift+mouseover solution, so he did not view any
comments, but did make some
Irritating when marking fails. This could happen in
information retrieval book because of invalid HTML
Conclusion (for now)
Too few users to draw conclusions based on results
Interview suggests that they like the concept and
would use it with more users
Interview suggests that there is at least a physiological
belief that sharing annotations will help find relevant
material
Prototype is good example of cross domain
communication using script tags and storing DOM
ranges
More conclusions will be drawn by comparing
prototype to previous work
Thank you for the attention!
