educational environments• contact-based, offline
• network (internet) supported
• blended
• distance education
• virtual education

learning environments
• personal (PLE)
• social interactivity-based (web2)
• personal activity-based (MOOC)
• instructional (LMS, LCMS)

current trends
• growth of information sharing space
• permanent possibility of the interaction
• the efficiency depends of the environment

online information sharing network
![Page 11: Information Sharing and Interaction in the Online Learning Communities](https://reader033.fdocuments.in/reader033/viewer/2022052600/557c8d50d8b42a6c788b4949/html5/thumbnails/11.jpg)
we calculate, we use, it's important for us:
• directed matrix
• whole network
• realized connection
• edge weight
• timeline of connections
• information type
• information quality
![Page 12: Information Sharing and Interaction in the Online Learning Communities](https://reader033.fdocuments.in/reader033/viewer/2022052600/557c8d50d8b42a6c788b4949/html5/thumbnails/12.jpg)
what's not important:
• personal (offline) friendship
• (other) social network relationship
• offline information sharing
• sharing to the group

frequent statistic measures:• degree centrality
• shortest path
• betweenness centrality
• closeness centrality
• diameter (longest shortest path)
• eigenvector centrality!
• local clustering coefficient
• graph density
![Page 25: Information Sharing and Interaction in the Online Learning Communities](https://reader033.fdocuments.in/reader033/viewer/2022052600/557c8d50d8b42a6c788b4949/html5/thumbnails/25.jpg)
(Abraham-Hassanien-Snasel, ed. 2010)
"Eigenvector centrality is a measure of the importance of a node in a network."
"A player’s degree of “popularity” within the network, i.e., they represent centers of large
cliques in the graph. A node with more connections to higher scoring nodes is considered as being more important."

• the "importance in the network" does not correlate with relevant content sharing activity
• It correlates with other content sharing activity (for example: social noise, pretence activity)
• is social media really useful in educational communication?!
• hopefully: there are differences between different methodology used groups
eigenvector - content sharing activity

• the "importance in the network" does not correlate with relevant content sharing activity - any groups
• the online activity are useful only in the open, regular course group ("little MOOC")
• there are the social media noise significance as well
eigenvector - content sharing activity
![Page 28: Information Sharing and Interaction in the Online Learning Communities](https://reader033.fdocuments.in/reader033/viewer/2022052600/557c8d50d8b42a6c788b4949/html5/thumbnails/28.jpg)
conclusions of correlation matrix• small groups, small networks - small conclusions :)
• #1 online communities (social networks) can be very spectacular but are not useful for educational process
• they can help the communication, but there are a big irrelevant social noise
• there are differences between groups
• #2 connectivism in small groups can develop "social market", but connected knowledge is unsure
• #3 hybrid environment (offline, online, 3D) obviate the bridge role in the information network
• #4 in an open online course the activity can be better quality than other groups
