Exercise (30 minutes)Discussion/brainstorming on effects of new media on learningAnd/orDesign exercise re socio-technical balance of pedagogical intent and media use
Goals of the Workshop3Part 1To familiarize you with Social Network concepts and gain an understanding of a Relational Perspective for researchWarning networks are addictive!To show how network perspective can be applied to questions about learning and knowledge building online, offline & blended, formal, informal & non-formalPart 2To introduce how new media disrupt traditional network connectivity, open up new opportunities, and forge new connectionsConsider how new media change learning practices
A bit about meMy Background and Interests
How do people work, learn and socialize together at a distance and through computer media?Communication, Collaboration, Community
Studies : Online Learning NetworksSocial networks / virtual communitiesDistributed learners / e-learningCollaborative research teams / distributed knowledgeInformation sharing and learning / ubiquitous learning
New directionsCrowds and communitiesSocial media and learningLearning analyticsA few theoretical orientations
Relational perspective who does what with whom as the unit of analysis
Sociotechnical perspective practice, observed behaviour, technology use, etc. arises from the interplay of people and technology
social informatics, organizational informatics, community informatics
Social and Technological Network Effects on Individuals and SocietyPart I: Trends
A Mosaic of Trends
(1) Social NetworksMore than just mediaA transformation in work and social organizationNetworks, communities, crowds===============Social Network Analysis - an approach, method and vocabulary for addressing societal structuresActors such as people, groups or organizations, tied by relations that form networks, analyzed and displayed as graphs
Rainie & Wellman, 2012, Networked: The new social operating system.
(2) E-LearningMore than a transfer of learning to an online stageLearning unbound from institutional structures, embracing flow across physical, geographical, disciplinary boundariesSustained over a lifetime, enacted in multiple, daily instancesMobile, learning from and in new and different locations as needed and on the devices at hand. Engaged act created through both technical and social decisions

(3) Participatory CulturePersonal but shared needCreative CommonsChanges in authority structuresPeer production, Peer evaluationDiffering by enterpriseCrowds, CommunitiesMotivationsPublic Good, CareerOutcomesSocial Capital, Community Resilience, Knowledge distribution

(4) Big DataProliferation of data and information streamsDynamic, Small to HugeGeo-locatedNeeding collection, management, analysis, presentation, validation Ethical, intelligent useData, information, analytics and visualization literacy
When you automate, you informate (Zuboff)
Learning Analytics14Learning analytics is the measurement, collection, analysis and reporting of data about learners and their contexts, for purposes of understanding and optimising learning and the environments in which it occurs.https://tekri.athabascau.ca/analytics

II. Social Networks, Learning Networks
QuestionsToday How can network perspectives be used to examine learning and education processes?What needs to be done to build a network analytic base for learning?How can what is known in social network research be used to jumpstart learning networks research?

Network PerspectivePersonalDoes the individual have in their network access to sufficient resources?How is the individual engaging with their network?CommunalAre there sufficient ties and resources within the network to support communal awareness, action, solidarity?Are there sufficient external connections to support access to newinfo. ?

Social Network PerspectiveNot just pretty picturesA method for social analysis: social network analysisA relational approachEmphasis on what people do togetherWho talks to whom about what? Who gives, receives, shares what kinds of resources? Who learns from whom?A network approachAttention to network structures and their outcomesHow does the structure of a network affect resource flow among group members? When do resources reach others? What resources can network members access?

InteractionsRather than aggregates of behaviorsOn average, 6000 tweets are sent per second, of these types: Pointless babble 40%; Conversational 38%; Pass-along value 9%; Self-promotion 6%; Spam 4%; News 4% (Pear Analytics. 2,000 tweets 2009 US in English)Examine behaviours in terms of social interactionPointless babble is social grooming (boyd, 2009)Information posting via Twitter comes with expectation of reciprocity (Holton et al, 2014)Actors in closer relationships (work, friendship) communicate more often, about more things (Granovetter and others), and via more media (Haythornthwaite & Wellman, 1996)

What do we know so far about social networks?27Social Networks Research
Some Key SNA Findings28Individual/Dyadic/TriadicRelational multiplexityStrength of weak ties (Granovetter)Strength of strong ties (Krackhardt, Granovetter)Forbidden triangleOrganizationalStructural holes (Burt)Diffusion of innovations (Rogers)Gatekeepers, Technological Gurus (Allen); Absorptive Capacity (Cohen & Levinthal)Internet/Media effectsMedia Multiplexity (Haythornthwaite & Wellman)Latent Ties (Haythornthwaite)Crowds and Communities (Haythornthwaite )
SocietyCommunity lost, saved, liberated (Wellman)Core discussion networks (McPherson & Smith-Loven)HomophilyBirds of a feather flock togetherTransitivityTendency for our friends friends to be our friends Inclusion/ExclusionOrganizational work hours and places support homophily (Smith-Loven)Social mobility (Lin)Social capital (accessed and mobile) (Lin)
Weak and Strong TiesWeak Ties . . . Acquaintances, casual contactsTend to be unlike each otherTravel in different social circlesResource exchangesInfrequent, instrumentalFew types of resources, exchanges, relationsLow motivation to shareStrength of weak tiesExperience / Information /Attitudes comes from a different social sphereBut, no obligation to share . . . Strong TiesFriends, close friends, team-matesTend to be like each otherTravel in the same social circlesResource exchangesFrequent, multiple types: emotional and instrumental High level of intimacy, self-disclosureReciprocity in exchangesStrength of strong tiesMotivated -- obliged -- to share what resources they haveBut, access to same resources
Societal ConnectionsCommunity Lost, Saved & Liberated, and now Networked (Wellman)Lost. Lament for the passing of the pastoral ideal of community, lost in urbanizationSaved. Rediscovered local community amid the towers of urban livingLiberated. Social network based (Wellman, 1979) place independent, liberated from geography, sustained through phone and travelNetworked the New Operating Systems (Rainie & Wellman, 2012)Personal communities networked individualism sustained through ICT, networked living, wireless connectivity
Neo-liberated. Finding career, work, friends, homophilous others through computer networksHyper-liberated. Unbound by boundaries of organizations and traditional workplacesFree of constraints of single career, employer, institutionlearning within institutional boundaries (e.g., MOOCs)human capital resource locationsingle author/ publisher/curator Community now found in myriad multi-threaded instances
