So, let us start with the first question, what are these emerging learning spaces?
At a recent conference Peter Hartley presented a framework to investigate the emergence of different online learning spaces for students and challenges for the different stakeholders with this emerging model.
One of the principles of this new model is the shift in ownership towards the student, where they are taking more responsibility the process of their learning. In other words, with the increase in availability of web based tools combined with the increasingly sophisticated and personalised use of these by students (Student Expectations Study (JISC, 2007)) then the traditional model of an institution providing all the required online tools is being seriously questioned. The emergence of the next generation virtual learning environment (or even a personal learning environment) is depicted in Figure 1.

Two important observations can be made from Figure 1, firstly, the trend within the tools, for instance, the inclusion of myspace, youtube, flickr, as well as other file stores. Secondly, the more diverse but interconnected these tools then the student can develop and maintain more diverse social networks.
So accounting for this interms of learning spaces then Peter Hartley suggests three distinct spaces (see Figure 2). It is very important to observe that these overlap at the margins. Also these maps differ for the different types of students (age, discipline, experience), and the interaction between the learning spaces will create tensions and need to be managed.

If we starting to unpick the characteristics of these spaces then the,
The use of this framework will easily allow us to map the needs of the mobile learner in various authentic learning situations. For instance, if we think of a placement student who is away from campus for a few months collecting data in the field, then they may have the following needs;
Given the multiple audiences that the placement student needs to engage with and the use of the mobile device (not a desktop or laptop) then the student is likely to want to control the software that is used. As opposed to having it locked away within the institutional software. Therefore, the likelihood is that much of the information and activity will be undertaken in the play ground and refuge learning spaces, for instance, on private blogs, image sites, and file repositories.
Against this it would also be argued that due to economies of scale the supervisor may wish to use the institutional software to manage their interface with the placement student. They may also wish to have an archive of the interactions. Therefore, the academic may favour the use of the institutional space as opposed to trying to manage the diversity of the student controlled spaces.
This is relatively easily accommodated within the Blackboard (and other VLEs), through the use of rss technologies, folders, changes to the navigation and being aware of which tools work more effectively with mobile devices and then optimising their use. Figure 3 outlines the flow of information between the spaces.

The later part of this discussion will be addressed in more depth in later posts.
dear andy - this was very interesting - am looking forward to the next
bits:-)
The idea of a shift in ownership of the learning process towards
the student also sits well with a more student centred approach to learning
- though I suppose this involves more than just letting the students chose
what applications they wanted to work in:-) But as a tutor you may need to
spend more time negotiating your assessment criteria with your students to
be sure that you have access to the elements of the learning process that
you want to be able to see. If there's a shift in emphasis towards
developing and rewarding skills that help people become lifelong learners
what will you ask students to show that indicates this?
There's also all the other *stuff* associated with students working in
environments the institution doesn't supervise and control - data loss and
use, practically supporting students using multiple applications - should
we even try-, impact on less technologically savvy students if we don't -
and also with collaborative work how applications are chosen and how group
processes are managed and facilitated. All surmountable and not mobile
learning specific but perhaps requiring thought;-)
