Personal Learning Environments in the Cloud?

January 24th, 2010 by Graham Attwell

I am surprised that there has not been more discussion of the UK Open University’s decison to sign up to Google Education for cloud computing services.

On his blog Niall Sclater says:

“In our first foray into cloud computing, Google will be hosting for our students:

  • email (gmail)
  • contacts
  • instant messaging and presence
  • calendar
  • document creation, storage and sharing
  • websites”

Interestingly, The OU, the UK’s largest univeristy, will not at the moment be giving staff access ot the system, presumably becuase of concerns over security and confidentiality.

Niall explains the reasons for the decision :

“Growing numbers of institutions are now adopting cloud-based systems such as Google Apps for Education, particularly in the US. The arguments for hosting your own student email are becoming increasingly weak when it can be done externally for free, or at least much more cheaply. Google will provide a service level agreement with higher levels of availability than we could achieve ourselves. In addition there are other services included such as instant messaging that we don’t currently provide to students but could help them to connect more with each other.”

However the decision has interesting implications for pedgogic approaches. Niall says:

“These systems will increasingly start to compete with some of the features of learning management systems / virtual learning environments such as Moodle and Blackboard. They provide a higher level of individual control for students and potentially remove some of the administrative burden from the university. …

Another area for investigation is the use of Google Apps as an eportfolio system. Our initial research has shown that it would work for some of the key aspects of eportfolio provision such as the storage of documents under the control of the user, the exporting of these so they can be taken with them through life, and the creation of templates for the collection of structured data for a variety of purposes. We still need to work out how we can freeze or export eportfolio content where it is being for formal assessment.”

In a comment on the blog, Tim Hunt, also from the Open University, says:

“The VLE is the University’s space where it publishes its courses, and students come to study that material and perform some course-specific activities.

Google tools / ePortfolio / PLE / student’s own laptop are the student’s spaces for keeping and managing their learning.

In a traditional bricks a and mortar, chalk and talk setting, the VLE is the lecture room and labs; and Google tools are the student’s room in the hall of residence, or possibly their leaver-arch file.

I think it is clear that you need both types of space, and that they complement each other. However, there are some activities that could take place in either space.”

Manish Malik from Portsmouth University, which is already giving access to Google cloud services to all students, tries to distinguish between PLEs, VLEs, loosely coupled applications and what he calls a “CLE or Cloud Learning Environment”

The cloud can be seen as one big autonomous system not owned by any educational institution. Let the Academics or Learners be the users, of some cloud based services, who all equally share the privelages like control, choice, sharing of content etc on these services. Then this is different from a PLE, a VLE and a PTE. For example Google Apps for universities is hosted on the cloud, not fully controlled by any educational institution and certainly not owned by one. The tools on it are to a great extent academic or learner controlled. Each “Google Site”, for example, can be owned by an academic or a Learner and both users be given the same rights/control by one another (depending on who creates first). Likewise Google Docs can be owned and shared between learners themselves or learners and academics under their own control.

This gives all parties the same rights on same set of tools. This clearly has potential to enable and facilitate both formal and informal learning for the learner. Both the academic and the learner are free to use the tools the way they wanted and share and collaborate with anyone they wanted.”

I think Malik is wrong is distinguishing between PLEs and CLEs (and to be honest, we really need just to advance our understandings of PLEs, rather than invent yet more acrobyms and terminology). If we go back to the blog entry which strated it all – Scott Wilson’s “The Future VLE?”, it was always clear that a PLE would include different third party services  (even though cloud computing was not a term invented then as far as I know).

However, there are a number of interesting issues raised by the move towards cloud services for students.

Firstly, the services provided by Google make it very easy for s student to develop their own PLE. One of the long running concerns about PLEs has been whether or not all students have the knowledge and skills with technology to develop their PLE. This may overcome such concerns. Furthermore, in a podcast interview with Niall I made three years ago, he expressed the concern that university computer services had a duty to provide support for all applications a university was using for tecahing and learning. If PLEs were to be introduced he argued, this would be impossible due to the very diversity of different platforms and applications. Presumably, the deal with Google overcomes that issue.

Of course it is all to easy to see Google as the new evil empire, taking over education. But unless the nature of the deal between universities totally ties down systems, it should be relatively easy to integrate third party services with the Google apps, at least for someone with reasonable digital skills. And although Niall Sclater refers to ePortoflios, I see little difference in the way this is developing to a PLE.

Of course, there are worries about trusting a PLE to third party commercial companies. But data is not locked down on Google in the way it is on platforms like Facebook. it should be relatively simple for a learner to keep copies of important work and data on their own computers (and indeed to update those copies when they change computers).

Interesting, from my present interests, it  should be relatively simple to integrate Google apps with the Android platform, this making mobile learning much cimpler (ignoring of course the problems with cross paltform use).

Of course the proof will be in the use. Will teachers start moving to Google apps rather than use the Open Univeristiy’s Moodle platform? Will learners develop their own PLEs? How will the Google apps integrate with univeristy services and applications. Will data be secure and will Google continue to support student PLEs even after they have left university: Is this just a new form of lockin? And how reliable are Google services? Do the moves by Portsmouth and the Open University herald a large scale shift by educational institutions to cloud services?

Most of all – will the use of these services provide new pedagogic affordances which will lead to changing practices in teaching and learning? Tims will tell.

  1. Some day, our institutionalised minds will realise we are providing to people what they already have, dumbing them down with homogeneous experience, .. the internet is the platform.

    I’m with you on the view that using the cloud to host either a PLE or VLE for that matter doesn’t need a new acronym any more than host it on a Mac instead of a PC server would need a new name for it.

    I also agree that there are interesting times ahead for the OU and others who adopt this approach if staff do decide to up sticks and move from hosting things in the ‘safe haven’ of a VLE to ad hoc solutions externally especially if they do so without any support or guidance from appropriate experienced parties. I think there is potential here for such an approach.

    I do see the idea of using google docs as an e-portfolio system a bit like trying brain surgury with a Swiss army knife. Sure, a Swiss army knife is a great tool and really useful, but there are times when you really need the /right/ tool.

    I’m sure with enough effort, a workable portfolio system could be kludged together and made to work – and if google are listening to HEI’s needs, I wouldn’t be surprised to see them put most of that work in too. I know that MS live @edu were talking seriously about developing specialist features for edu for their offering almost a year ago (I don’t think that’s breaking the NDA), but I’ve not seen anything public come out in that direction yet. I’m sure if MS have recognized that as needed, google must have too.

    I’d love to see google pick up the open source moodle by the scruff of the neck and really integrate it and provide it then as a fully hosted VLE/PLE integration solution…:)

    Ermmm.. My first name is Manish. Malik is my surname/title given to my family few generations ago.

    My question to you is: Do students have PLEs when they come in to a univeristy? Do they all develop it during their course? If not then what practice are we talking about? Do they use it when at work? or when looking for a new job? By the way I am not against PLEs, they are the way to go for becoming a life-long learner and building and expanding your learning network.

    Tim Hunt’s comment on Niall’s blog shows how the education system suffers with the formal-informal divide. The way in which VLEs/LMS/CMS are used reflects this very divide. Learning is not just formal or just informal as we all know. I think Tim Hunt agrees with that as he says, “there are some activities that can take place in either space”. A CLE within an educational institution will provide means of supporting formal as well as informal learning. Many academics find new opportunities where they can be a part of both formal and informal learning activities and are successful in that.

    As an example of above, majority of my students use past exam papers as an informal learning approach for exam preparation. Some academics may not promote or engage in this activity at all. However, i have used this informal activity with my students, on my examopedia site, to:
    a) collectively engage them with content through guidance and facilitation
    b) facilitate peer-support for those who dont have it
    c) identify general areas of weakness of the entire class and provide formal just-in-time teaching if necessary.
    For one of this year’s examopedia site (live) see http://bit.ly/4G4tBT

    The term VLE reflects the the existing culture within institutions in its current use/implementation.

    May I urge the people who read this also cast their vote on my blog. The question of the Poll is “what would they rather have for their Institution PLE/VLE/CLE/Chalk n talk” – note that its asking about their institution not personal/life-long learning. Linked via my name at the top of this comment.

    This I hope will provide students with the exposure to technologies they can use when they gradute and go and work as while at the institution a PLE is no good for formal education. In practice people use a PLE when at a higher level in their education or career. So, as I said to you earlier, I see CLEs as a pre-cursor to PLEs for those who go on choose to use a PLE when they graduate or even in their higher years during their education.

    Digital Literacy

    A National Survey fin Wales in 2017-18 showed that 15% of adults (aged 16 and over) in Wales do not regularly use the internet. However, this figure is much higher (26%) amongst people with a limiting long-standing illness, disability or infirmity.

    A new Welsh Government programme has been launched which will work with organisations across Wales, in order to help people increase their confidence using digital technology, with the aim of helping them improve and manage their health and well-being.

    Digital Communities Wales: Digital Confidence, Health and Well-being, follows on from the initial Digital Communities Wales (DCW) programme which enabled 62,500 people to reap the benefits of going online in the last two years.

    Zero Hours Contracts

    Figures from the UK Higher Education Statistics Agency show that in total almost 11,500 people – both academics and support staff – working in universities on a standard basis were on a zero-hours contract in 2017-18, out of a total staff head count of about 430,000, reports the Times Higher Education.  Zero-hours contract means the employer is not obliged to provide any minimum working hours

    Separate figures that only look at the number of people who are employed on “atypical” academic contracts (such as people working on projects) show that 23 per cent of them, or just over 16,000, had a zero-hours contract.


    Resistance decreases over time

    Interesting research on student centered learning and student buy in, as picked up by an article in Inside Higher Ed. A new study published in PLOS ONE, called “Knowing Is Half the Battle: Assessments of Both Student Perception and Performance Are Necessary to Successfully Evaluate Curricular Transformation finds that student resistance to curriculum innovation decreases over time as it becomes the institutional norm, and that students increasingly link active learning to their learning gains over time


    Postgrad pressure

    Research published this year by Vitae and the Institute for Employment Studies (IES) and reported by the Guardian highlights the pressure on post graduate students.

    “They might suffer anxiety about whether they deserve their place at university,” says Sally Wilson, who led IES’s contribution to the research. “Postgraduates can feel as though they are in a vacuum. They don’t know how to structure their time. Many felt they didn’t get support from their supervisor.”

    Taught students tend to fare better than researchers – they enjoy more structure and contact, says Sian Duffin, student support manager at Arden University. But she believes anxiety is on the rise. “The pressure to gain distinction grades is immense,” she says. “Fear of failure can lead to perfectionism, anxiety and depression.”
