#H800 Communities of Practice, Networked Individualism, Network dynamics and Mycorrizhal networks

Communities of Practice

The concept of Communities of Practice (COP) was introduced by Lave and Wenger (1991) to highlight and conceptualize forms of learning that focus on participation and are not limited to the individual level (don’t stop ‘at the skin of the individual’).  Legitimate peripheral practice is the conceptualization of the apprentice learning a craft with a master, thereby gradually developing mastery in the subject.  In this way he showed that learning was an inevitable aspect of all productive practices and not limited to a formal setting within schools or institutions.  The communities in the COP can be characterised as:
-       Clearly bounded structure, with rules for membership.
-          Single centre of supreme skill and mastery
-          A hierarchical structure where new members (apprentices) start at the ‘periphery’ and gradually move toward the centre of the community as they obtain mastery.  Also called a ‘centripetal’ structure.


However, recent work by Engeström (2007) challenges Wenger’s analysis by pointing out oppression by dominant figures in communities, and rebellion by apprentices. Therefore, learning is not smoothly and necessarily centripetal. Instead, the movement of learning is shaped by learning’s participants. Those at the hub of the learning experience would appear to exert the greatest influence.

Jones focuses on the successful application of network dynamics in other domains, such as transport and politics.  This enables applying mathematical network ‘laws’ on learning networks, such as power laws, clustering and the strength of weak ties.  Networks can be identified from the level of societies and institutions down to individuals and ideas.  Individuals can be nodes in a network, engaging in linking to other persons, agents and resources.  Or, nodes can be formed by ideas with associations between them forming the links of the network.  His ideas remind me of Connectivism - also discussed in an earlier blog post-, which claims to be a learning theory for the internet age, that also considers learning as building networks, not only of physical persons, agents of learning resources, but of associated ideas.

Engeström considers COP as a-historical structures, which means that they are not connected with the varying dominant organisational structures in a society.  According to Engeström, COP fit within a society dominated by craft and industrial production.  Craft is characterised by a master-apprentice relationship and industrial production is characterised by teams, small groups with well-defined membership, with members who have complementary competences and work together on certain task.  Gradually a ‘co-configuration’ model evolved in which companies became more susceptible for input from customers and other outside sources (co-creation of value as described by Prahalad and Rawasmamy, 2004).  Adler and Hecksher (2006, cited in Engeström, 2007) call the organisational structure for the post-industrial society a ‘collaborative community’

A collaborative community is different from a team in 4 aspects:
-          Boundaries become more fluid;
-          Very high level of division of labour and diversity of knowledge;
-          Authority based on knowledge and expertise instead of status;
-          Values are orienting and motivating elements for members of the community. The increased importance of motivation follows from looser membership rules.

Engeström points out that such a collaborative community is no longer a team, but a network.

Social production and the mycorrizhae analogy

For Engeström the organisational structure of the information society is social production. The flagship example of social production is the open source movement.  Thousands of developers and bug fixers work together in a loosely-structured network without a clear centre – although one could argue that one of the success factors of the Linux and Moodle open source networks is the role of their respective leaders -, but with a compelling common goal, called ‘runaway objects’.  Examples are global warming or a free operating system.

Engeström develops an analogy with a mycorrizhae system.  This is a symbiotic relationship between a fungus and the roots or rhizoids of a plant.  The fungus delivers nutrients and water to the plant, which returns the favour by providing the fungus with energy-rich sugars.

The analogy plays as follows:

-          A underground network of roots with interspersed nodes resembles a loosely connected and expanding network of individuals, exchanging information and with multiple loyalties.
-          Visible fungi resemble the visible, erect, bounded and institutionalised structures that emerge from this network.  Engeström uses the term ‘wildfires’ to describe sudden bursts of activity – in the same of a different place - with long dormant periods in between.
-          There is no hierarchical structure in mycorrizhae as is the case in the root system of plants.
-          The mycorrizhae work in symbiosis with plants, as informal learning networks can work in symbiosis with formal structures.
-          The mycorrizhae is hard to kill, but also vulnerable due to the lack of clear leadership.

Networked individualism

The model is very suitable for a mobile generation of learners, who form temporary networks, dominated by weak bounds, very easily.  Castells (2008) calls this a ‘networked individualism’, claiming that not mobile, but individual is the defining property of the mobile generation, since people experience a much higher freedom.

Final remarks

These post-industrial organisation modes and the mycorrizhae analogy that describes it, seem fit to explain learning activity in a Web 2.0 environment.  Students are developing personal learning networks (PLE) as a complement to the institution’s system (VLE), in which they communicate not only with their peers, but with a wider network of friends, and possibly alumni, bloggers, staff and domain experts.  Twitter seems to me the ultimate tool to facilitate this kind of weak-tie dominated networks, much more than Facebook, which seems to have a more personal and bounded network structure  - An interesting analysis how Google + mixes weak-tie and strong-tie networks was made here by George Siemens.  Traditional classroom practice can be described as a community of practice, with a clear master (the teacher), a bounded membership structure (the classroom) and a clear, externally defined objective (the curriculum and assessment).  The current trends in (higher) education towards a more student-centred learning approach, with a higher responsibility for the student to create a learning network, more flexibility in courses and more fluid boundaries between formal and informal learning seem fit with a network approach and a mycorrizhae analogy.
