2. A New Social Scenario
› The role of technology in the learning process and in a more collective
knowledge construction
- The unprecedented presence of technology in our lives has had a significant
impact on how we communicate and collaborate with each other.
- New ways of collaboration through media channels such us YouTube, Flickr, and
Twitter (among others) have changed our user expectations and we have made
many of these platforms an important part of our social interaction.
- Despite the attractive advantages presented by scholars about the impact of
technology in the learning process, there is still a lack of understanding of the
dynamics of social interaction within learning communities.

3. Research Motivating Questions
› Is there an interplay between social networks, learning and performance?
› If so, what is the role of social learning in the inherent relationship between
properties of social networks and performance?
› How does one quantify and measure learning within a social context?
› How does one account for social network properties of structure, relations
and position in modeling learning for the purpose of learning analytics?
3
4. Our Proposal
› A theoretical model based on social learning and social network theories to
understand how knowledge professionals engage in learning and
performance.
4
5. Conceptual Foundations
› Learning is a highly complex process, which involves cognitive, affective,
individual and social dimensions [48]
› Social learning theory suggests that individuals learn through the
observation of the behavior of those they are connected with [2]
› To whom individuals are connected is critical for reaching unexplored
sources of novel information and then satisfy a determined necessity [14,15]
› There are fundamental contextual factors that affect learning (positively and
negatively) [32]
› Human and Non-human sources of information and knowledge [46]
5
6. Models of Learning
› Situated Learning Theory (SLT) [32]
- Communities of Practice [52]
- Legitimate Peripheral Participation
- SLT presents an interesting perspective to analyze learning from a social
networks point of view
- But, it does not consider Non-Relational sources of information such as
databases, webservers, blogs and discussion forums among others.
6
7. Models of Learning
› Connectivism [46]
- Learning is permanently affected for new conditions in the environment and the
knowledge that can reside in non-relational repositories
- But, the importance of dialogues between relational and non-relational sources
has been just partially covered [42]
- Dialogues defined as unit of social interaction help us to understand how network
connections and meaningful content interchange influence individuals’ learning
process.
- Dialogues persisted in non-relational entities provide a broader contextual
information for knowledge creation.
7
8. Understanding Learning and Performance
through Social Networks
› Social Networks Analysis (SNA)
- Study of social systems from a structural perspective through the identification of
behavioral patterns based on node and tie attributes [17]
- An individual’s social structure and its properties can influence the access to
valuable resources rich on novel information [5, 8, 14, 25, 33]
- Those new sources can have a direct or indirect impact on the individual’s
learning and performance [12, 13]
- It is interesting to examine theories that explain how information is disseminated
through networks and how network structures can impact learning and
performance
8
9. Understanding Learning and Performance
through Social Networks
› Strength of Weak Ties Theory [21]
- Tie is defined as “the combination of the amount of time, the emotional intensity,
the intimacy (mutual confiding), and the reciprocal services which characterize
the tie” [21]
- Granovetter’s study [21] shows how professionals found better job opportunities
through weak ties instead of strong ones
- The stronger the tie, the more redundant the information becomes
- The importance of weak ties is that more resources and novel information are
accessible through them
9
10. Understanding Learning and Performance
through Social Networks
› Structural Holes Theory [10]
- The effective and efficient exploitation of an individual’s position in the network
can provide important informational and control benefits
- Trade-off between the number of contacts and the novelty of information. The
more contacts the higher the cost of maintaining relationships
- The challenge is to maintain efficiently non-redundant connections that
increase the diversity and then the novelty of the information.
- The bridging between two or more unrelated cliques (group of contacts closely
connected within the group) is called a structural hole.

11. Towards a Social Networks Model for Learning
and Performance
› Given the unprecedented advancement in the adoption of social technologies, this
study provides evidence in the eLearning domain to help understand how networks
interact with technology to foster learning and performance in an era of digital
natives [4]

13. Context and Methodology
› The e-Learning Environment
- Online project management course delivered the second semester of 2009 at a leading
“Group of Eight (Go8)” university in Australia
- 36 full-time working industry professionals with diverse backgrounds.
- Students based nationally and overseas
- Complexities on coordination due to time zone differences
- Course material included lecture notes, tutorials, laboratory exercises and videos all
accessible through the university’s eLearning platform WebCT
- Synchronous (chat) and asynchronous (discussion board) communication channels
- Public and private discussion forums (Students dialogues)
- Individual and group assignments. 12 groups each of them with no more of three
participants
- Virtual collaboration
13
14. Context and Methodology
› Data Collection, Storage and Extraction
- Data collected from the public and private discussion forums
- 825 public forum messages and 722 private forum messages
- Unstructured nature of the message logs
- Preliminary data preparation (Extraction of message attributes from HTML)
- Information stored in a MySQL database
- Java application to extract the node and tie data from the database for
generating the input file for UCINet (statistics) and NetDraw (sociograms)
14
15. Context and Methodology
› Message Content Classification
- A meaningful exchange of dialogues among team members is instrumental for enhancing
their learning process.
- By identifying the patterns of communication among team members it is possible to study
the structural properties of the group’s social network.
- Those patterns of communication have been categorized in past research according to
varied dimensions such as length of messages [34], channel of dissemination [34,39], content
[34,38], and meaning [19], but none of them used a social network perspective.
- In this study we have defined a classification method based on message content and
meaning in order to categorize each message sent through the public an private forums.
- Each category defined has a weight associated which indicates the level of Content
Richness of the messages classified on it. The higher the value the more significant are the
messages of the category.
15
16. Context and Methodology
› The defined Content Richness categories are:
• Empty Message: Inexistent content, file exchange without dialogue, greeting messages
• Team Building Message: Personal introductions and very basic coordination. Final group
closing activities, congratulations for group achievements and recognition for mutual
cooperation
• Dissemination Message: Information about group submissions and notifications about new
document versions.
• Coordination Message: Team meetings (critical time zone difference)
• Collaboration Message: Knowledge creation. Problem solving dialogues. Individual and
group insights about the course and activities.
16
17. Context and Methodology
Weight Content Category Message Example
0 Empty “Thank you Peter”
1 Team Building “Excellent work team”, “Has been a pleasure working with
you guys”
2 Dissemination “I submitted the last version of our report”
3 Coordination “Lets meet tomorrow at 7pm Sydney time”
4 Collaboration “Dear Peter I think your answer to the question is correct.
However, I found this article in which the authors analyze the
issues from a different perspective. Please consider also …”

28. Discussion
› We argue that rather than performance, social learning is influenced by
social networks properties such as structure, relations and position.
› The relationship between social networks and performance is mediated by
social learning.
› Studying how individuals interact and organize themselves (SNA) can be
useful to improve learning programs and positively influence performance
during and after the studying period.
› Content Richness was shown to be a good predictor of social learning due
to the interesting findings that connect the measure with most social
network properties modeled.
28
29. Limitations
› Size of dataset
- This was an exploratory study that can not be generalized to the entire population but
the results are indicative of the power of social networks influencing learning and
indirectly, performance.
› Message content classification process
- Is still in an early stage and subject to criticism. We believe that the construction of a
taxonomy or vocabulary for group communication in studies of linguistics and
semantic data mining could allow the partial or full automation of the process
› Most of messages took place within groups
- There was not enough evidence about the interaction among groups. However,
according with our results, the quality of dialogues within groups was significant.
› Other collaborative tools were not considered
- A future research could include those interactions through video, chat and voice.
29
30. Conclusions
› Development of a theoretical model for understanding the impact of social
networks in learning and performance
› Construction of a content-based measure called Content Richness which
provides an approach for measuring the level of engagement of learners in
social environments.
› Analysis of individual and group communication patterns of students located in
different cities, countries and time zones.
› Rather than performance, social learning is highly influenced by the learners’
social network properties.
› Model proposed would allow educators, professional development leaders,
managers and academics to enhance learning analytics and make informed
decisions and estimations of learning outcomes

Editor's Notes
So, this motivates our research that is focused on figuring out …
Network Structure: There is a significant negative relationship between network density and CR score, r = -.406, p (one-tailed) < 0.01. In terms of social learning, this result makes sense because is better to have a few high level meaningful dialogues, rather than many meaningless conversations. Given this result, we find support for H1.Network Position: Network efficiency is significantly correlated with CR score, r = .394, p (one-tailed) < 0.01. Highly efficient learners are connected with contacts that are expected to provide good quality of content (high CR), so they can fulfill the informational needs of the learner without having to look for other sources. This result provides us with evidence to support H2.Engagement: There exists a significant positive correlation between CR and CI (r = .344, p (one-tailed) < 0.05), thus lending support to H3a.According to the Gloor’s definition of CI, an optimal contributor would present a balanced rate of messages sent compared to the number of messages received. Therefore, the CI value should tend to be zero for optimal communication. The conclusion that we can make from this result is that learners with higher CR score send more messages than they receive, and as a consequence, there is no reciprocity in terms of meaningful content exchange for social learning. In addition, CR score is significantly negatively correlated to E-I index, r = -.354, p (one-tailed) < 0.05, thus allowing us to reject H3b. In the case of E-I index we are also looking for a balanced rate of internal and external communication [30]. A high E-I index indicates a relatively higher communication by an individual to those outside his group relative to those internal to his group. This is beneficial for avoiding ‘group think’. According to the results obtained, those who communicate more frequently internally within groups relative to externally outside groups are also engaged in higher or richer levels of communication. This can be attributed to the fact that the large number of internal group messages in comparison to the external ones influences the E-I index. In fact, there were more interactions between group members, rather than among external contacts, which indicates that learning as evidenced by content richness took place within groups rather than outside of groups. This result is very likely due to the large number of internal dialogues.Network Ties: There is a significant positive relationship between the average strength of ties and CR score, r = .422, p (one-tailed) < 0.01. Therefore, there is sufficient evidence to reject H3c. The stronger the tie the more frequently the contacts occur. This implication means that contacts with high level of interaction tend to mutually exchange valuable information. These dialogues are rich in content and provide more in depth insights about the topics of learning. Although Granovetter’s theory may not hold true in this circumstance, other researchers have claimed that strong ties are symbol of closeness and trust, which are two determinant components for social learning [29, 32]. Performance: There is a significant positive relationship between CR score and the individual assignment marks, r = .311, as well as between CR score and the quiz mark, r = .341, both p (one-tailed) < 0.05. However the exam result, which has the highest assessment weight in terms of learning outcome, does not seem to be significantly associated with CR score and for none of the engagement measures proposed in this study. Taken altogether, we consider that these results are somewhat indicative enough of how meaningful dialogic exchange among contacts can enhance learners’ performance. Therefore, we find partial support for H4.
