Abstract
Social and mobile technologies offer users unprecedented opportunities for communicating, interacting, sharing, meaning-making, content and context generation. And,
these affordances are in constant flux driven by a powerful interplay between technological innovation and emerging cultural practices. Significantly, also, they are starting
to transcend the everyday lifeworlds of users and permeate the workplace and its practices. However, given the emergent nature of this area, the literature on the use of social
and mobile technologies in workplace practices is still small. Indeed, social media are
increasingly being accessed via mobile devices. Our main focus, therefore, here is on the
question of what, if any, potential there is for the use of social media in informal,
professional, work-based learning. The paper provides a critical overview of key issues
from the literature on work-based learning, face-to-face and technology-supported, as
well as social (mobile) networking services, with particular attention being paid to
people tagging. It then introduces an initial typology of informal workplace learning in
order to provide a frame for understanding social (mobile) network(ing) services in
work-based learning. Finally, a case study (taken from the literature) of People Tagging
tool use in digital social networks in the European Commission-funded MATURE project
is used to illustrate aspects of our typology.
Introduction
In 2011, social networks and associated technologies have continued to gain in importance
in people’s everyday lifeworlds. Research by Pew Internet, a nonpartisan, nonprofit “fact
tank,” suggests that 66% of online US adults use social media (see Smith, 2011 and http://
mashable.com/2011/11/15/social-media-use-study/). With the growth of (the market share of)
smartphones—with 35% of US adults owning a smartphone—it hardly comes as a surprise that
mobile social media are also enjoying a period of growth by 37% in 2011 according to analytics
firm comScore. Social networking apps appear to be the main driver for this development
(http://www.readwriteweb.com/archives/comscore_mobile_social_networking_app_audience_

Practitioner Notes
What is already known about this topic
• The importance of social networks and associated technologies in everyday life and
commerce.
• Some conceptualisations of learning through and at work exist, but they tend to be
based on the empirical study of professionals and graduate employees.
• The concept of tagging in relation to digital resources is well established.
What this paper adds
• A consideration of the use of social networks in learning in informal and work-based
context.
• An exploration of some of the affordances of social media for work-located learning.
• A widening of the concept of tagging to the classification of knowledge embodied in
users and their social networks.
• A typology of factors in social network(ing) services and work-based learning.
• An analysis of a case study of people tagging in relation to the typology of factors.
Implications for practice
• A conceptualisation of aspects of technology-enhanced and enabled learning through
and at work.
• An understanding of the potential of social media for work-located learning.
• A realisation of some of the potential of the use of social media in informal, professional work-based learning.
continue. These trends are not confined to the US. According to comScore, the number of people
accessing social network(ing) sites (SNSs) in France, Germany, Italy, Spain and the UK has gone
up by 44% in 2011, with 55 million users in these countries doing so on their mobile devices, an
increase of 67% compared with the same month a year earlier (http://www.pcworld.com/article/
244399/social_networking_use_among_mobile_users_grows_in_europe.html). In a survey
with 15 000 respondents across six continents by GSMArena in March 2011 (http://www.
gsmarena.com/mobile_phone_usage_survey-review-592.php), engagement in social networks
was the eighth most favourite mobile phone feature overall.
Unsurprisingly, in the fields of education and educational research, social media have also started
to attract attention, albeit not always in a positive way. Cases of teachers putting their careers at
risk either by revealing too much personal information online and thereby risking becoming too
familiar with pupils or by commenting unfavourably about their pupils or employers online are
eagerly picked up by the media (http://www.bbc.co.uk/news/uk-scotland-16379494).
This paper aims to provide a new perspective by bringing a critical review of work-based learning,
SNSs and tagging together into a typology, which is then illustrated with a case study of a People
Tagging tool in digital social networks taken from the European Commission-funded MATURE
project. We are particularly interested in contributing towards a deep understanding of social
phenomena and experiences here and offer our analysis of one case study with the intention of
providing an initial frame for gaining a better understanding of what is currently a new and
underresearched area. Consequently, the focus is mainly on a conceptually coherent analytical
approach and not so much on the findings themselves, which are intended to be indicative only.

Critical overview of key issues from the literature
Given the breadth of the scope of our topic across the subdomains of work-based, informal and
mobile learning as well as SNSs, invariably difficult choices have to be made here when presenting
relevant background literature in view of the limited space available. For this reason, we will
discuss SNSs broadly in order to establish general principles that can subsequently be explored
with specific reference to mobile devices. As we have sought to show in the introduction, social
networking is increasingly a phenomenon played out on mobile devices.
Work-based learning, face-to-face and technology-supported
A critical review of the way technologies are being used for work-based learning (Kraiger, 2008)
found that most “solutions” are targeted towards a learning model based on the ideas of direct
instruction in a formal manner, eg, transferring lectures and seminars from face-to-face interactions to computer-mediated interactions. Recent work has started to explore approaches that seek
to harness the affordances in particular of mobile devices around learning in informal contexts
(see, eg, Pachler, Pimmer & Seipold, 2011). The question arises: what is known from empirical
work on face-to-face work-based learning to inform our perspectives on what it may be possible to
achieve with social and mobile media-mediated work-based learning?
The field of work-based learning, within which learning through and at work is discussed, is a
contested field often driven by national and supranational policy discourses such as those around
employability or life-long learning. Often, the term “informal learning” is used to capture related
processes in the workplace to set them apart from formal education or training (see, eg, Eraut,
2004, p. 247). We find the notion of “informal learning” problematic at various levels most
specifically because we question whether fundamentally different cognitive (and social) processes
are at work and therefore prefer to use the term “learning in informal contexts.” Notwithstanding
these reservations, we recognise the fact that the term “informal learning” is widely used and
define it as follows:
a natural activity by a self-motivated learner “under the radar” of a tutor, individually or in a group,
intentionally or tacitly, in response to an immediate or recent situation or perceived need, or serendipitously
with the learner mostly being (meta-cognitively) unaware of what is being learnt (Pachler & Cook, 2009,
p. 152).
Work-based and informal learning are discussed at a range of different levels in the literature.
In this paper, we focus on literature that is empirically founded. One key proponent of an
empirical tradition of work-based learning research is Michael Eraut. There are, of course,
other important scholars in the field, such as eg, Sawchuck (2010), Evans, Guile and Harris
(2009), Illeris (2007), or Livingstone (2006), to name but a few. Given the significance and
internal coherence of Eraut’s work, as well as its connectedness to other scholarship and
research in the field, we use it as a basis for our conceptual thinking here. Eraut’s (2000, 2004,
2007, 2008) work also has been derived mainly from the study of professionals and graduate employees rather than workers more widely. The fact that this is the intended target
audience for our discussion of (people) tagging later makes Eraut particularly suitable for our
purposes.
Eraut (2000, p. 116) inter alia identifies the following features of informal learning, which he
presents as part of a “typology”: implicit linkage of memories with current experience; reflection
on as well as discussion and review of past events; observing and noting facts, ideas, opinions,
impressions; asking questions; engagement in decision making, problem solving. By 2008 (Eraut,
2008, p. 409), the typology had been refined into that shown in Table 1.
Eraut (2007, p. 406) posits that these features by-and-large play out in the following four types of
activities:

• Assessing clients and/or situations (sometimes briefly, sometimes involving a long process of
investigation) and continuing to monitor them;
• Deciding what, if any, action to take, both immediately and over a longer period (either individually or as a leader or member of a team);
• Pursuing an agreed course of action, modifying, consulting and reassessing as and when
necessary; and
• Metacognitive monitoring of oneself, people needing attention and the general progress of the
case, problem, project or situation.
What is of particular interest for our purposes here is the fact that the majority of learning
activities through and at work seem to involve other people, eg, through one-to-one interaction,
participation in group processes, working alongside others, etc. This, for us, underlines the centrality of identifying relevant “others” from and with whom to learn—and the possible role of
social media and SNSs in it—particularly given the documented problems in the transfer of
knowledge between people in the workplace (see Eraut, 2008, pp. 15–18): the heterogeneity of
most workplaces in terms of human resources are undoubtedly a strength as well as a challenge
in terms of asset identification and management. How best to identify and access relevant expertise? A related challenge for less as well as more established colleagues is that of (perceived)
vulnerability associated with power relationships and giving the appearance of lack of knowledge
and expertise, etc.
The art of discourse about practice then becomes one of establishing affinity with colleagues
through work-related discourse and giving the appearance of being generally cooperative,
without giving anything away that might increase one’s vulnerability (Eraut, 2008, p. 16).
In this section, we have provided a critical overview of key issues from the literature on workbased learning, face-to-face and technology-supported; in the next section, we examine social
(mobile) networking services.
SNSs and social media
One of the early and often cited papers on SNSs is that by Boyd & Ellison (2008). In it, the authors,
in addition to charting the history of social network sites and setting out some relevant research
questions, offer a definition of SNSs as:
web-based services that allow individuals to (1) construct a publish or semi-public profile within a bounded
system, (2) articulate a list of other users with whom they share a connection, and (3) view and traverse
their list of connections and those made by others within the system.
Also, they make the distinction between social networking sites and social network sites preferring the latter term as the former, according to them, emphasises relationship initiation. The term

715
social network, they argue, reflects the fact that users are primarily communicating with people
“who are already part of their extended social network,” ie, they augment pre-existing social
relationships and interactions. We use the generic term social network(ing) services here in an
attempt to acknowledge Boyd & Ellison’s distinction and to reflect the importance of the services
offered by these sites. Merchant (2011, p. 5) considers the way in which SNSs support public
displays of friendship and connections to be one of their unifying features. Compared with other
writers on the topic, Merchant considers SNSs as part of what he calls “the wider textual universe” of online communication (p. 5), and he discusses them in relation to more “traditional”
notions of social networks, “the patterning and flow of communication, friendship, intra- and
inter-group behaviours as they are enacted in and across different geographical locations and
over time” not mediated by social media (p. 6). This notion that SNSs have the potential to include
people beyond currently existing social networks seems to us to be an important characteristic, as
we shall see later when we discuss the MATURE case study.
The existing literature on social media suggests that at best, more work is required to maximise
the potential of their affordances for learning in formal contexts (eg, see Crook, 2012). The
literature on technology and social media use and “informal learning” (eg, see Sefton-Green,
2004) on the one other hand tends to be characterised by a certain lack of definitional clarity
about what can best be understood by “informal learning,” how (social) media practices in
everyday life can be harnessed in formal learning (eg, see Pachler, Bachmair & Cook, 2010) and
by a focus on personal learning environments. Furthermore, Dabbagh and Kitsantas (2011),
with reference to the work of others, see agency as “a change of self-representation based on
psychological needs such as competence (perceived self-efficacy), relatedness (sense of being a
part of the activity) and acceptance (social approval)”; all of which, they view as acts of selfregulated learning. The concept of self-regulation is an important one, and this can be seen to be
linked to the notion of agency used by Pachler et al (2010) in their sociocultural ecology of mobile
learning. Indeed, these issues were summarised by Eraut’s observation based on empirical work
(Eraut, 2004, p. 269) that factors affecting face-to-face learning in the workplace, such as feedback, support, challenge and the value of the work, can lead to individual self-efficacy in terms of
confidence and commitment. One approach to providing computer-mediated support is for selfefficacy and self-regulation scaffolding. The use of scaffolding as a metaphor refers to the provision of temporary support for the completion of a task that a learner might otherwise be unable
to achieve. Van de Pol et al’s (2010) review of a decade of research on face-to-face scaffolding
suggests that this work seems to “point largely in the same direction, ie, that scaffolding is
effective” (p. 286). In terms of computer-supported scaffolding, approaches to semantic and
adaptive scaffolding (Azevedo, Cromley, Winters, Moos & Greene, 2005), and metacognitive scaffolding for self-regulation (Pol, Volman & Beishuizen, 2010) have shown promise.
In the next section, attention will be paid to the literature on and the notion of people tagging, as
this appears a productive line of inquiry for work-based learning.
Tagging and people tagging
It would go way beyond the scope of this paper to offer a comprehensive discussion of the
extensive literature on tagging. Therefore, we confine ourselves to a few key issues, which we
consider to be particularly pertinent in relation to the question of the potential for informal,
professional, work-based learning.
Tagging ostensibly enables users of social media to add labels to digital resources in order to help
them refer to them easily at a later point. Huang, Liu and Tsai (2011) offer a useful discussion of
tagging in relation to cognitive load theory. They argue that the learner’s working memory is
essentially a cognitive system of limited capacity and that, therefore, a learner’s performance is
affected by cognitive load. They go on to distinguish three types of cognitive load: intrinsic,
© 2012 The Authors. British Journal of Educational Technology © 2012 BERA.
716
British Journal of Educational Technology
Vol 43 No 5 2012
extraneous and germane. The first type, intrinsic cognitive load, “is determined by the inherent
nature of the materials and learners’ prior knowledge.” Extraneous cognitive load “is caused by
an improper instructional design.” And, germane cognitive load “is resulted by an appropriate
instructional design” . . . that “can motivate learners to indulge themselves in the processing,
construction, and automation of schemas and them store them in their long-term memory”
(p. 3).
Fundamentally, two types of tagging can be distinguished: folksonomies, ie, a user-driven, collective system of classification, and ontologies, classifications determined by a system and/or its
providers. Many papers discuss the relationship between folksonomies and ontologies (see, eg,
van Damme, Hepp & Siorpaes, 2007). Folksonomies, such as social bookmarking, are characterised by variability and lack of systematicity in the use of tags and, therefore, ontological clarity.
This creates a need for an agreement of implicit semantics (Aranda-Corral & Borrego-Díaz,
2010).
There also exists a small body of literature on people tagging, an approach to the classification of
the knowledge embodied in users as well as their social networks rather than of digital artefacts.
One immediate challenge arises around the descriptors to be used to characterise people in your
professional network through tags, particularly as the knowledge embodied in people remains
often tacit, is normally multifaceted and usually is liable to frequent change. Unlike some of the
literature in the field, which is interested in the notion of people tagging from the perspective of
efficiency gains and cost reduction in relation to professional relationship formation and management (Braun, Kunzmann & Schmidt, 2010; Farrell & Lau, 2006), we are interested in it
primarily in relation to learning (through and at work). In order for such systems to work, the
research suggests (see, eg, Farrell, Lau, Wilcox & Muller, 2007), one cannot rely on each employee
to create and keep their profile up-to-date but needs to seek “to leverage the work of a few active
taggers” (p. 2). Some particular challenges in the field of people tagging are the use of potentially
objectionable tags or the disclosure of sensitive data.
Social networking approaches to workplace learning have tended to focus on describing and
augmenting employee profiles from the perspective of those profiles being used for expert finding
and community formation. These platforms are mainly based on the self-promotion paradigm,
whereby people can represent themselves with a profile and indicate their connections to other
users. Further, in some of these approaches, the principle of social tagging and bookmarking is
transferred to people; for instance, Linkedin (http://www.linkedin.com/), Xing (http://www.
xing.com/) and Collabio (http://research.microsoft.com/en-us/um/redmond/groups/cue/
collabio/) (short for Collaborative Biography) developed by Microsoft (the latter is no longer
active). Linkedin and Xing have mobile phone apps available for them. Of relevance to this paper
is Collabio’s interest in the quality of tags and encouraging social connectedness (Figure 1).
Braun, Kunzmann and Schmidt (2012) describe Collabio as follows: “Users can tag their friends
in a game. Therefore, the users only see the tags assigned to a friend in an obscured tag cloud.
When they start to describe the friend, guessed tags are uncovered and new tags are added to the
tag cloud. For each tag, the users accumulate points equal to the number the tag is assigned to the
friend. Only the friend him-/herself can see the whole uncovered tag cloud, who assigned which
tag and delete tags if needed. However, self-tagging is not possible. To prevent the cold-start effect
of a completely empty tag cloud, seed tags are used from a person’s public profile.”
Rajagopal, Brinke, van Bruggen and Sloep (2012) offer a conceptualisation of personal learning
networks with particular relevance for our focus on people tagging. Rather than foregrounding
the technology, they concentrate primarily on “the act of making connections with other professionals” and the skills associated with it. Key to these skills, they argue, is “the ability to identify
and understand other people’s work in relation to one’s own, and to assess the value of the

Figure 1: Collabio (Source: Bernstein, Tan, Smith, Czerwinski & Horvitz, 2009, p. 1) (The user has guessed

dots until the user guesses them.)
connection with these others for potential future work.” Clearly, technology in general, and SNSs
in particular, has a valuable contribution to make in the process of creating (a) personal network(s) of people distributed across groups and places, and various degrees of connectivity and
interconnectivity. Among the benefits cited by the authors are the development and growth of
one’s professional career, access to support structures, professional development and knowledge
creation. In order to be able to make the best use of the learning opportunities from personal
learning networks, Rajagopal et al (2012) posit that users need to perform the following three
primary tasks: “building connections (adding new people to the network so that there are
resources available when a learning need arises); maintaining connections (keeping in touch
with relevant persons); and activating connections with selected persons for the purpose of
learning.”
Finally, Rajagopal et al (2012) note that in the skills layer of their model, which also includes an
activity and attitude layer that we do not discuss here, technologies can offer various functionalities to support personal networking such as enhancing communication with people in the
network, remaining in touch, positioning an individual in the network, and finding people and
expertise. People tagging can be seen to be one advanced functionality supporting the learning

process in and through personal networks. In particular, they can be seen to address one important aspect on SNSs, namely credibility through what Jessen and Jørgensen (2012) call “social
validation”; building on the work of others, they propose a model of aggregated trustworthiness
where perceived credibility = social validation + authority and trustee + profiles.
In the next section, we introduce an initial typology of informal workplace learning that takes
into account our review of key issues from the literature. The purpose of this endeavour is to
provide a frame that will, hopefully, assist our understanding of social (mobile) networking
services in work-based learning (analysing current examples and providing suggested lines that
could be explored in future endeavours).
An initial typology of factors in social (mobile) network(ing) services and
work-based learning
Our typology of factors in social (mobile) network(ing) services and work-based learning
are represented textually in Table 2. The derivation of the main nodes was made after going
through the literature variously over several months and coming back to the simple focus presented by Eraut (2004, p. 269) who summarises the “Factors affecting learning in the workplace,” calling them Context and Learning Factors. The Context Factors node-branches were

derived directly from Eraut’s (2008, p. 18) “A typology of Early Career Learning” (see Table 1).
The key elements of the critical literature review were added to the Learning Factors node; this
was required because Eraut’s body of work deals with face-to-face learning. In this sense, we have
extended Eraut’s work. Finally, it became clear that a specialised node for People Tagging Factors
was needed. Thus, the Learning Factors node is generic and hence includes branches surrounding personal learning networks, whereas the People Tagging Factors are very specific. As noted
earlier, in the main, our typology (a checklist) seeks to serve as an explanatory, analytical frame
as well as a starting point for discussion about attendant issues, rather than provide a definitive
map of the field. We also want to stress that there is insufficient space here to represent and
discuss each of the subbranches of the typology in any detail. That said, the case study of
MATURE elaborates on our typology in a real work-based context.
Case study of the MATURE project
This section provides a brief case study of a People Tagging tool, used in digital social networks,
taken from the European Commission-funded MATURE project. The MATURE Project (http://
mature-ip.eu) conceives individual workplace learning processes to be interlinked (the output of
a learning process is input to others) in a knowledge-maturing process in which knowledge
changes in nature. This knowledge can take the form of classical content in varying degrees of
maturity but also involves people, tasks, and processes or semantic structures. The goal of
MATURE is to understand this maturing process better based on empirical studies with users to
give guidelines and to build tools and services to reduce maturing barriers. MATURE systematically makes use of a design research approach that has included Use Cases that were linked
to personas (developed from an ethnographically informed study) and particular knowledge
maturing activities. One important continuing aspect of the MATURE work is the “people
dimension” of the project, which aims at improving the development of knowledge about
other’s expertise and improved informal relationships based on a People Tagging tool pilot study
(Braun et al, 2012); the tool was developed by the Forschungszentrum Informatik (FZI) (http://
www.fzi.de/), the scientific coordinating partner of MATURE. Note that the People Tagging tool
is different from Callabio. Braun et al (2012) describe the People Tagging tool approach as
follow:
Semantic people tagging is based on a combination of the principles of (a) collaborative tagging of persons
. . . and (b) social semantic bookmarking . . . Employees assign tags to each other (e.g., on entries in an
employee directory, from their address book, or as a bookmark to social networking sites like LinkedIn)
referring to expertise or interests. This can be [used to] complement self-assessment and the assignment of
tags by superiors. These assignments are not restricted to a predefined competence catalogs, but the
employees can use (almost) any tags which they find appropriate, although tags are recommended based
on those already used by others. Tags can be collaboratively developed towards a shared ontology, negotiated among the users of the system. This is achieved through a gradual formalization (as part of everyday usage) following the concept of ontology maturing . . . i.e., new tags are first added to a category of
‘latest topics’ from where users can merge synonyms and typos, or add translations, and put them in a
structure of broader and narrower terms. More formal definitions can be added, too, so that the entries
evolve from informal tags to more formal competency definitions usually found in competency catalogs . . .
This can serve several purposes and use cases. (1) Colleagues can find each other more easily, e.g., for
asking each other for help. (2) Employees become aware of other colleagues with similar interests or
experience to stimulate the formation of communities. (3) It supports human resource development by
providing information about the aggregated needs (e.g., by analyzing searches) and current capabilities of
current employees (aggregated tagging data) to make the right decisions about training required. By
extending the group of people who can make competence and expertise assignments to encompass colleagues, semantic people tagging promises to achieve (1) a higher up-to-dateness and completeness of the
employee profiles, (2) more realistic assessment of competencies and expertise than with self-assessment,
and (3) additional awareness for the tagged person who can see his/her colleagues’ perspective. At
the same time, assignments by colleagues come with social risks, e.g. by the assignment of inappropriate
tags.

Our typology-driven analysis would, we predicted, surface use and design implications for workbased SNSs and these are expanded upon later in more detail in the Discussion section. Later,
we use a qualitative analysis of a “wider description of people tagging approach” and then an
associated “pilot study” (both taken from Braun et al, 2012; we refer to this as the case study
Parts 1 and 2) to illustrate aspects of our initial typology. Where we see a mapping between the
earlier typology and the text of the case study, we will note the relevant link in the context of
descriptions of the case study in italics-brackets (we call this a node-branch). For example,
node-branch (3a) refers to node 3 (ie, People Tagging Factors) and branch a (ie, efficiency
gains).

“Knowing-who” (3c) is an essential element for efficient knowledge maturing processes, eg, for
finding the right person to talk to in order to solve a task-oriented problem (1a). Many approaches
like self-descriptions in employee yellow pages or top-down competence management approaches
have largely failed to live up to their promises. This failure is often because information contained
in the directories becomes outdated quickly (2d iv) or is not described in a manner relevant to
potential users. MATURE uses a lightweight ontology approach based on collaborative tagging as
a principle to gather the information about persons inside and outside the company (if and where
relevant); individuals tag each other according to the topics they associate with this person (3d iv)
(Figure 2).
FZI call this “people tagging” and claim (Braun et al, 2010) that it can use this to gain a collective
review of existing skills and competencies (3a). Knowledge can be shared and awareness
strengthened within the organisational context around “who knows what?” (Implied 3a). This
tagging information can then potentially be used to search for persons to talk to in a particular
task. Moreover, it can also be used for various other purposes. For instance, FZI claim that human
resource development needs to have sufficient information about the needs and current capabilities of current employees (2b i) to make the right decisions about training requirements. In this
context, the people tagging approach can provide an indication of:
• What type of expertise is needed?
• How much of the required expertise already exists within the organisation?
• What gaps in specific skills and competencies exist?
Of course, this is a very formal approach in viewing learning needs, and hence and at first sight,
we may see that this approach is missing many informal learning factors (2). However, in terms
of the earlier questions, Braun et al (2012) have observed that “each target context of a people
tagging system will require a different ‘configuration’, which depends on cultural aspects (2d iv)
as well as the actual goals that are associated with introducing people tagging. An analysis of the
state of the art has shown that there has been little research on identifying design options in a
systematic way so that we have developed a framework for engineering people tagging systems.”
FZI go on to propose a useful conceptual design framework for semantic people tagging systems.
The framework is based on results and experiences with field experiments, expert focus group
together with an analysis of the design of folksonomy-based systems in general in the literature.
The framework has five main aspects: (1) involved people, (2) control and semantics of the
vocabulary, (3) control of tag assignments, (4) visibility of tag assignments, and (5) search
heuristics for flexible search strategies. For example, in terms of who is allowed to tag (1), restrictions can range from anyone being allowed to tag or a limited group of persons who are allowed
to define tags, limited either by organisational structures (eg, team colleagues) or individual

relationships (eg, friends or approved contacts in a social networking service), or allowing only
self-annotation. These options may be combined with each other (3d i).
Case study Part 2: pilot study set-up and results (Braun et al, 2012) (analysed using the typology)
The People Tagging tool was introduced to and formatively evaluated in two phases with Connexions Northumberland (Careers Guidance service, UK) between October 2009 and July 2010.
This is a local organisation that provides service for young people aged 13–19 years (up to age 25
for people with special needs). It helps with decision making about study, jobs and careers by
offering impartial information, advice, guidance and personal support. Connexions Northumberland had, at that time of the study, 60 employees geographically distributed over the whole
county. “Because of the geographical distribution, the people’s knowledge about the specialties
and expertise of their colleagues is very limited [a]cross the offices and finding the right colleague
to talk to is difficult” (Braun et al, 2012). Employees in this study were allowed to tag themselves
and their colleagues without any further restrictions; tagging of external contacts was not envisioned. Thus, it was possible to tag any colleague without the taggee’s explicit opt-in (3d iv). The

employees are intended to use their own initiative to develop and modify the vocabulary used for
tagging. The system has been initially evaluated in a first cycle over 1 month as a pilot at the
beginning of the project:
We introduced the system in a hands-on workshop to ten employees. Additional employees have shown and
explained the system to their colleagues so that they started using the system as well. In the introductory
workshop we presented a short demonstration that was followed by an initial questionnaire on expectations
and a user trial session with guided tasks. Then the employees used the system 16 in an unsupervised way.
After four weeks, a second workshop was held where we collected the experiences with using the system
(Braun et al, 2012).
Results specifically show that the simplicity of the system was attractive and important (being
perceived as a “Facebook for work”) (2c iii); although little knowledge maturing could be
observed within the limited period of evaluation (ie, 1 month), there were insights into related
notions of sharing and building expertise (2d i), reflective practice (2b). Furthermore, Braun
et al (2012) have reported that participants stated that they “also liked the way it can give them
lots more information than they currently have and the basic philosophy of democracy which
empowers the individual (2d iv) and where nobody is in charge but has all possibility to contribute (currently they often feel out of control because there is no possibility to easily contribute to a shared knowledge base like eg, the intranet).” However, various areas of concern were
also identified: (1) there should be a “use by date” for tags; it is important that a person tag is
time-bound so people who have this tag do not feel that they are making a completely openended commitment (2d iv); (2) “lazy-practice” issue, here, some practitioners may abuse the
system where, eg, “lazy” colleagues may resist entering details about themselves and may tag
others with expertise they may have (to deflect additional queries) (2d iv); and (3) “sharing
could increase workload” (2c ii). On the last issue, Braun et al (2012) note that “there were
concerns about sharing whole people tagging information with other services in general
because it could also increase the workload.” It can be noted that the organisation currently
continues to use the system, and FZI are collecting usage logs to study the tagging behaviour
more closely.
Typology-driven overview and discussion of the People Tagging study
Briefly, from the earlier qualitative analysis embedded in the text of our case study, we can see that
the typology is readily applied to the MATURE case study. The mapping of the nodes and branches
in our typology, as mentioned in the earlier case study, is summarised by the list in Figure 3.
Examining the node-branches of our typology can be seen as one way of assessing the current
status of a project or initiative in terms of the factors from our typology that are found present in
a specific case.
Figure 3 shows the result of a qualitative analysis of the text of the case study. In our discussion,
where we claim a node-branch “cropped” up, we mean that the text in the case study corresponded to a specific node-branches in the typology. For example, in Figure 3 “(1a)” means that
this node-branch (ie, Context Factors-Work process with learning as a by-product) appeared in
the text on one occasion. When we say “(2d iv = 5),” we mean that this node-branch–sub-branch
(ie, Learning Factors-personal learning networks-aggregated trustworthiness) was identified on
five occasions, and so on. When we claim that a node-branch(–sub-branch) “cropped up in a
peripheral manner,” we mean that the node-branch in question was not identified or was only
mentioned in the case study text in passing (a subjective conclusion).

By examining the node-branch list (Figure 3), we can make the following observations: Learning
Factor node-branches surrounding individual self-efficacy (2a) and node-branches around selfregulation (2b) only cropped up in a peripheral manner or not at all. Node-branches around
cognitive load, ie, 2c i-iii, cropped up twice. First, concern was raised that “sharing tagging could
increase workload” (2c ii), ie, cognitive load extraneous (improper instructional design); indeed,
the case study explored this and the design approach for introducing People Tagging in an
organisation explicitly factors in this issue. Second, the case study results appear to show that the
simplicity of the system was attractive and important (being perceived as a “Facebook for work”),
ie, (2c iii) cognitive load germane (appropriate instructional design motivates); the People
Tagging tool design was perceived by participants in the case as having potential to assist them in
their work practice. No explicit mention was made of 2c i cognitive load intrinsic (inherent nature
of the materials and learners’ prior knowledge); this was probably due to the brief nature of the
case study. Node-branches around personal learning networks (2d i-iii) were difficult to detect in
the case study; these node-branches would seem to be areas where computer-based scaffolding
could be needed to provide guidance. Node-branch surrounding aggregated trustworthiness (2d
iv) cropped up five times as an issue (shown by “ = 5” in Figure 3), and this is an indicator that is
clearly worthy of further exploration. The current state of the art in computer-mediated scaffolding revolves around the design and use of a distributed e-learning repository, content creation
and customisation, or social networks. However, the social-network(ed) dimension of scaffolding
across multiple contexts in workplace informal and formal learning has largely been ignored. The
challenge is to make sure that individuals can make use of the increasing ability to make connections to people. In contexts such as Connections Northumberland, they can do this in a
social-networked context using mobile devices where required.
Clearly, there are limits to the work presented in this paper, particularly given the exploratory
nature of our work in an area that is currently underresearched. A limitation of the analysis of
the People Tagging tool case study using the typology is that no independent rater was used to
validate the codes as applied to textual descriptions of the case. Such an approach is not, in our
view, appropriate at this moment given the exploratory nature of this research into a complex set
of social, individual and technological issues. However, this may become a topic of future
research. Instead, we focus on an exploration of an innovation (the People Tagging tool case
study) using a typology derived from a critical review of the literature. Also, a question could be
asked about what efforts were taken to disprove the typology. Again, as our approach is exploratory and not one of hypothesis testing, this was not really central to our research.
We hope to have demonstrated that the typology has strong analytical power even if we take into
account the earlier limitations. The first author has presented the typology from this paper to the
MATURE consortium meeting (January 2012) who have agreed that it should be used to provide
a micro- and meso-level framework for analysing the final Summative Evaluation reports of
MATURE. Thus, the typology will be tested over the coming months (March–May 2012) against
diverse cases from MATURE, several of which do not focus on people tagging. The opportunity to
use our typology in this way will allow us to further test and validate our approach.
Conclusions
The purpose of this paper was to attempt to answer the question: what, if any, potential there is
for the use of social media in informal, professional, work-based learning. We conclude that
the potential is considerable, although there is need for further work. The analysis of the
MATURE People Tagging tool case study has, we claim, proved productive, and we suggest
that the typology we have developed has the potential to provide a fruitful tool for further exploration of the field. For example, on the basis of our analysis earlier, we can see certain gaps in the
sense that of some node-branches were absent in the MATURE case study analysis (Figure 3); on

this basis, we claim that learning factor node-branches that would seem to be areas where future
work on computer-based scaffolding could be needed are: individual self-efficacy (2a), selfregulation (2b) and personal learning networks (2d). Thus, the purpose of our critical review,
typology and qualitative analysis using a case study from the literature have been to provide a
frame to assist our understanding of social (mobile) network(ing) services in work-based learning. Rather than provide a definitive map of the field, our typology (or checklist) provides an
explanatory, analytical frame and as such a starting point for the discussion of attendant issues.
