Introduction
Technological advancements and pedagogies that emphasize learners as co-producers of knowledge (Selwyn 2011) have contributed to peopleās adoption of the term social media to indicate websites and online applications that enable users to create and participate in various communities through functions such as communicating, sharing, collaborating, publishing, managing, and interacting (Mao 2014; Social media, n.d.). Typical social media features promote individual users through profile pages (e.g., displaying likes, comments, recommendations). Social media features include interconnections with other users through links and news feeds, and sharing of user-generated content (e.g., photos, ratings, tags). Pages can be dynamically updated and content embedded (e.g., embedding a video). Examples of social media include social network sites (e.g., Facebook); wikis (e.g., wikispaces); media-sharing services (e.g., YouTube); blogging tools (e.g., Blogger); micro-blogging services (e.g., Twitter); social bookmarking (e.g., Delicious); bibliographic management tools (e.g., Zotero); and presentation-sharing tools (e.g., Slideshare) (Gruzd, Staves, and Wilk 2012).
It has been argued that educators would benefit from āa stronger focus on studentsā everyday use of and learning with Web 2.0 technologies in and outside of classrooms (Greenhow, Robelia, and Hughes 2009, 255). Others argue that only a small proportion of young people are actually using social media in sophisticated ways that educators might value (Eynon and Malmberg 2011; Ito et al. 2008). Complicating this tension, there is a lack of current models that theorize social media as a space for informal learning. There is also considerable debate about the benefits and challenges of appropriating technologies (e.g., social media) in everyday use for learning and little exploration of the connections between formal, non-formal, and informal learning such technologies might facilitate.
In this paper, we draw on relevant theory, prior literature and our own research in Europe and the USA to suggest a model that theorizes social media as a space for learning with varying attributes of formality and informality. Using ideas derived from social constructivism and connectivism as promising initial lenses through which to conceptualize social media and learning, this paper problematizes ālearningā and āteachingā across multiple contexts, illustrating the complex relationships between formal, non-formal, and informal learning. It considers research projects from two regions focusing on young peopleās uses of social media tools to support these varied forms of learning. Because our studies involve participants of varying ages, including teenagers and college-age youth, we refer to āeducationā broadly as spanning school and higher education contexts. We revisit the debate about social media, or āsocial softwareā in education to suggest how this model illuminates current tensions and suggests new opportunities for research and innovation.
Research on social media in education
The educational benefits of appropriating social media into learning contexts are contested. Research on social media in education suggests that integrating social media in learning and teaching environments may yield new forms of inquiry, communication, collaboration, identity work, or have positive cognitive, social, and emotional impacts (Gao, Luo, and Zhang 2012; Greenhow, Burton, and Robelia 2011; Greenhow and Robelia 2009a, 2009b; Pimmer, Linxen, and Grohbiel 2012; Ranieri, Manca, and Fini 2012). For instance, research on learning and social network sites (e.g., Facebook) in particular has suggested their affordances for interaction, collaboration, information, and resource sharing (Mazman and Usluel 2010); encouraging participation and critical thinking (Mason and Rennie 2007; Ajjan and Hartshorne 2008); increased peer support and communication about course content and assessment (DiVall and Kirwin 2012); inter-cultural language learning (Mills 2011); and their positive effects on the expression of identities and digital literacies, particularly for marginalized groups (Manca and Ranieri 2013).
On the other hand, researchers have warned against leveraging social media for learning. Kirschner and Karpinski (2010) found that time spent on Facebook negatively affected college grades. Similarly, Junco and Cotton (2013) examined how students multitask with Facebook and found that using Facebook while doing schoolwork was negatively associated with their overall grade point average. Studentsā use of social media in extracurricular activities was found to be distractive to learning, especially among weaker students (Andersson et al. 2014). Finally, students were less willing to appropriate social media as a formal learning tool, preferring it for course-related communication (Prescott, Wilson, and Beckett 2013) or using it largely for socializing and non-academic purposes (Selwyn 2009).
Despite a growing body of work concerned with social media and āinformal learningā, āthere has been little serious attention to the form or nature of that learningā (Merchant 2012, 16) or the interrelationship with formal learning (Cox 2013). Many studies consider appropriation of social media within āformalā and/or āinformalā learning, but in most cases, these terms are under-theorized or treated as binary conditions, which oversimplify the complexities of the actual learning contexts todayās youth inhabit. Some researchers suggest that appropriating social media can facilitate āseamlessā integration across learning situations integrating formal and informal learning (Dabbagh and Kitsantas 2012). Others highlight the challenges of appropriation (Crook 2012). Adopting a more āprincipled approachā to understanding these tensions and interrelationships is especially important in light of recent technological developments, policy initiatives, changing teacher and faculty demographics, and the realities of young peopleās access to social media. As described in more detail below, these converging trends suggest that it may be more useful and realistic to theorize social media as a space for learning with varying attributes of formality and informality.
Theorizing social media as a space for learning
Social constructivism and connectivism are promising initial lenses through which to conceptualize social media and learning with varying attributes of formality and informality. Social constructivism draws on the idea that learning is situated in the context of circumstances, activity or culture. What is known resides not only in the individual, a position advanced by cognitive constructivists, but also in the collaboration and interaction among many (Vygotsky 1978; Windshitl 2002). Conceptually, social media practices seem well aligned with social constructivist views of learning as participation in a social context and values of knowledge as decentralized, accessible, and co-constructed among a broad base of users (Dede 2008); āknowledgeā may become ācollective agreementā that ācombines facts with other dimensions of human experienceā (i.e., opinions, values) (Dede 2008, 80). Validity of knowledge in social media environments can be negotiated through peer review in an engaged community, and expertise involves understanding disputes and offering syntheses accepted by the community (Dede 2008).
Similarly, connectivist ideas (Siemens 2005), which view learning as the process of creating connections and articulating a network with nodes and relationships, also seems well aligned with social media practices. Connectivism can best be viewed as a developing perspective (Kop and Hill 2008) that overlaps with other more established perspectives like social constructivism; it is under-researched, but provides āfertile testing ground for ideas, which, in turn, may lead to empirical researchā that can then refine, validate or disprove the framework over time (Kop and Hill 2008, n.p.). Connectivism draws strength in using internet activity as a powerful and intuitive analogy for conceiving of distributed learning through networks; if learning transpires via connections to nodes on the network, then perhaps the maximization of learning can be understood by studying the properties of effective networks (Kop and Hill 2008). From the connectivist perspective, being knowledgeable can be seen as the ability to nurture, maintain, and traverse network connections; to access and use specialized information sources just-in-time; and...
