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!
