In-Depth Study of
Two Distributed E-Learning Classes
The Social Informatics of Elearning
Who talks to whom, about what, and via which
media?
How does the configuration of work requirements and
media use affect who talks to whom, about what, and
via which media?
How does this configuration affect interactions among
members of such groups?
Distributed Environment
The Social Informatics of Elearning
Distance Program
Master’s program for online learners
Initial face-to-face 2-week “boot camp”
All other courses completed at a distance
Students at a distance from campus and each other
Internet-based instruction and interaction
Lectures: Real-Audio and Chat
Homework & Assignments: Discussion Boards, Web
Pages, Email
Group-wide communication: Discussion Boards, Chat
Person-to-person communication: Chat whispers,
Email, Phone
Data Collection
The Social Informatics of Elearning
Each month for three months, members of two classes
were asked:
How often, over the last month, did you
1.
2.
3.
4.
With each other member of the class and via each of the
available media
Chat, Webboard, Email, Phone
At end of semester, also collected data on friendship
Collaborate on class work
Exchange information or advice about class work
Socialize
Exchange emotional support
Friend (Close Friend, Friend) or Non-Friend (someone they
worked with only, or just another member of the class)
Data were collected by phone. A student research assistant
called each person and asked them the questions.
Different Class Structures
The Social Informatics of Elearning
Class F97
Live lecture with Chat weekly
Bulletin board postings required weekly
Grading based on Group projects
14 members (13 participants)
Class F98
Live lecture with Chat weekly
Bulletin board -- used early but abandoned
Weekly exercises with different pairs of students
responsible for discussion each week
Grading based on Individual projects
19 members (15 participants)
Social Networks Basics
Actors
The Social Informatics of Elearning
Nodes in the network
Interact and maintain
relations with each other
Relations
Lines in the network
Connect actors in specific
kinds of interaction
Ties
Lines between actors
Ties exist between actors
who are connected by one
or more relations
Networks
Whole configuration of ties
and actors
Configurations of discussion board
conversations in two online classes
2001 and 2002
The Social Informatics of Elearning
Analysis
Social network analysis used to examine:
The size of the personal networks in these classes
How many people a class member reports interacting
with overall, and about each kind of relation
How media were used to maintain social network ties
How friendship affected media use
Changes over time
Friendship effects
The Social Informatics of Elearning
Friends talk to each other more frequently, about more
types of things (relations), and via more media
Regression analysis shows frequency of communication
(log) is positively associated with the number of relations
maintained and the number of media used in both
classes.

Differentiation between
Weak and Strong Ties
The Social Informatics of Elearning
Number of relations maintained and number of
media used increases with increasing frequency of
communication
“Media multiplexity”
Media use conforms to a unidimensional scale
(Guttman scaling)
(1) Chat + (2) Discussion + (3) Email + (4) Phone
Weaker ties (low frequency of communication)
Use only the media required for class: Chat and
Discussion Boards
Stronger ties (high frequencey of communication)
Use class media + optional media: Email, Phone
Changes Over Time: Relations
The Social Informatics of Elearning
In the first month, those who work together are those
who socialize together
From the first to the second month, network sizes and
range of relations increased
From the second to the third month, network sizes and
range of relations decreased
This suggests socializing as pre-requisite or co-requisite for
work relations
This suggests a wider circulation of ideas, information, etc.
during the second month
Over time, individuals engaged with fewer people
with whom they maintained more relations, i.e., with
stronger ties
F97: narrow to strong work relations
F98: narrow to those with whom they socialize
Dual Pattern of Media Use
The Social Informatics of Elearning
Unidimensional scale showed that
This shows
Required media connect weak ties
Optional media were added by those with stronger
work or social ties
(1) the type of medium selected by the instructor as
the required class medium has an effect on who talks
to whom via which media
(2) the type of tasks selected by the instructor as the
required class tasks has an effect on who maintains
strong ties with whom, and thus also who talks to
whom via which media
Let’s look at some pictures …
F97: Collaborative work via IRC and Email by Time
Chat
Month 1
Month 2
Month 3
Email
Group projects; Webboard also used for discussion, connected all to all.
F98: All communications, IRC and Email by Time
Chat
Month 1
Month 2
Month 3
Email
No group project; Rotating pairs for presentations; Webboard use started but
abandoned in this class; it connected very few after abandonment
Differences due to Class Structures
The Social Informatics of Elearning
Class F97
Semester-long projects created a focus on work-oriented
relationships and thus increased the importance of work ties
Interactions, including socializing, became highly organized
around project team members
Class F98
Changing pairs of presenters did not provide an enduring
basis for work-oriented relationships and individuals fell back
on social ties
Relationships become those associated with socializing,
built on non-work ties
Conclusions
The Social Informatics of Elearning
Different organizational mandates lead to the formation of
Two patterns of interaction for groups …
Different bases for relationships (e.g., work or social)
Different social structures
Different media use
Class-wide exchange of information
Task-focused work completion
And two patterns of media use
Low frequency, group-wide exchanges with the class as a
whole, supported through group-mandated media
Higher frequency, close-tie exchanges with team members
and friends, supported through group media plus optional
media
The Social Informatics of Elearning
Recommendations
The Social Informatics of Elearning
Awareness of dual demands for support of weak and
strong tie exchanges
Recognition of the impact of group-mandated means of
communication on group structures
weak tie contact for exposure to new information, and new
others with whom stronger relationships may be built
strong tie contact for completion of tasks, help in a crisis,
interpersonal support
creates a latent tie infrastructure through which weak ties
can be initiated
forms group media use structures
Recognition of the impact of group-mandated forms of
interaction on group structures
organizational decisions also lay the groundwork for latent
and weak tie formation
The Social Informatics of Elearning
Recommendations
Provide
a variety of means and opportunities for
communication, including means for
group-wide, public communication
person-to-person, private communication
technical, social and organizational interventions
that promote
group-wide sharing of information and resources
the growth of weak ties into stronger, selfsustaining ties
