Technology and ideology

I’ve just been reading a very interesting article by Alan Amory. ((Amory, 2010) Education Technology and Hidden Ideological Contradictions. Educational Technology & Society, 13 (1) 69-79 for those of you who like references.)  His argument is that educational technology, as we use it in higher education is driven by a distinctively neo-liberal mindset that reinforces the status quo, rather then doing anything to promote radical change, or indeed doing very much to promote learning. While acknowledging that learning technologies need not be used this way, he describes reusable learning objects as being based on “totalitarian ideologies of instruction”. I think what he means by this is that they present learning as a sort of “jigsaw” that can be assembled into a picture, which itself has been defined by the status quo. In other words they don’t easily allow for re-interpretation into a new picture. He describes learning management systems (like Blackboard) as “observation and control systems” and blended learning as “perpetuating the past” by simply bringing technologies into existing courses without making any pedagogical change.  On the whole, I’m inclined to agree, although I’m not sure I blame the technologies for the way they’re being used.

 

To steal his rather nice phrase, it promotes learning from technology, rather than learning with technology.  He goes on to argue for a much more social approach to learning – that we should see technologies as tools rather than objects, and use them to encourage students to work collaboratively to produce new learning, which of course sits quite comfortably with the Student as Producer project here at Lincoln. We certainly don’t want to see students as consumers of a rather ill-defined “educational product” that they pay £9000 (or whatever) for? I’m not going to get into the question of exactly what the cost of a degree covers, since I can’t see that you can buy something that you do yourself, such as learning. But Amory’s argument suggests that universities should principally be providing a space where people can learn socially, a space which may or may not be digital, although these days I would expect it to have quite a significant digital component.

 

The problem is of course that LMS’s aren’t often used to support social learning. Many would say, rightly, that they’re not designed to, but most of them do have some features which could be used to encourage it. Blackboard has wiki tools, and discussion groups for example, but these are still usually tutor led. Amory suggests creating learning spaces in virtual worlds, where students and tutors can work together to identify and resolve problems related to the discipline, I can see how that might work in theory, although I haven’t seen any virtual world software that is nearly accessible (or robust) enough to be deployed on an institutional scale, (although I  suppose they don’t need to be 3D worlds like Second Life – they could just as well be text based). The theory is, and I admit to over-simplifying here, that students and tutors form social networks, based on a shared interest in the subject. The members of the network then work together to identify and resolve problems of importance to the discipline. Which is all very well, but it doesn’t get us away from education as a commodity. Marks are a commodity which are exchanged for another, academic work. How do we measure individual student’s contributions for assessment purposes in this kind of learning? Does it matter? More to the point of this post, how can we get the kind of social networking Amory describes inside an LMS or VLE?

 

Lecture Capture

I’ve been getting more and more interested in “lecture capture” systems of late. These are systems that record a lecture on video, “chunk” it into sections and stream it to a virtual learning environment such as Blackboard. Clearly, this has the potential to go some way beyond the current practice of posting a set of PowerPoint slides on Blackboard, and leaving it at that. Of course, some colleagues at Lincoln have been experimenting with recording lectures, but the need to install appropriate software, marry audio and slides, secure recording equipment, and find a place to post it, mean that this is unlikely to be sustainable on an institutional scale.

What is interesting about lecture capture systems is that they don’t require a great investment in hardware. Panopto, for example, simply makes use of existing computers, web cams and microphones, and the quality of the end product is apparently quite good. (Although, I have to say the sound quality on their demonstration videos was dreadful on my PC, which didn’t inspire confidence.) This post though, isn’t about the technology or the cost, important though those matters are, but more about the pedagogical implications. I have a feeling that many colleagues will be rather nervous at the idea of recording lectures. Surely, they will ask, if students know that the lecture is recorded, they won’t come at all. Not only that, once the lecture is in the can as it were, why would the University continue to employ them?

Well, I could give a flippant answer, and point out that any teacher who can be replaced by a machine probably should be, but I suspect that would not be helpful. So here’s some evidence from the sector.
At Aberystwyth, as of Winter 2010, there were more than 18 different modules using Panopto… A student survey conducted in December 2009 found that students view Panopto as a great tool for reviewing course material and studying for exams.

At Northampton, the first two departments to trial Panopto were the Business School and the School of Health. Lecturers and tutors got involved and were surprised at how easy Panopto was to use. They also loved the fact that it integrated seamlessly with Blackboard. Di Stoncel, Principal Lecturer in the School of Education, made a recording of a guest speaker, which was then broadcast to students, with great success. She said “I have found it to be very useful and easier to use than I expected…It is unobtrusive and has opened up several opportunities which have enhanced the student experience.

Admittedly, the above examples are taken from Panopto’s own publicity material, but at a recent meeting at Loughborough (which uses a different system, Echo360) several speakers claimed that attendance had gone up at lectures, student satisfaction was increased, and, (probably something of a by product) the sartorial standards of teaching staff had dramatically increased! The main issue was simply ensuring that lecturers stayed within the camera’s viewpoint.

While I haven’t looked at this in any detail, I noticed that both Panoptico and Echo360 seem to have open APIs, which suggests that we might be able to do all sorts of interesting things with the data they generate. By “we” of course, I mean “people who know about this sort of thing”.

So, I don’t think lecture capture is necessarily anything to be afraid of. Clearly, further investigation is needed, something I propose to do. There’s an event in London next month, which I plan to attend, and if I am able to do so, will blog about it. So watch this space.

Blackboard v Moodle

And while I’m in blogging mode, I thought this comparison of Blackboard and Moodle, effectively the two leading VLEs in the sector, was interesting. Of course it’s only one case, but it suggests while both seem adequate to the job, Blackboard seems to be somewhat ahead on ease of use. That’s quite significant, since a VLE won’t be used at all if colleagues find it difficult to use.

Personally, I’ve no strong feelings one way or the other about which VLE we should use, if indeed we should use one at all. I do think the framework that VLEs provide is quite helpful, especially if one is not a particularly confident user of technology, but we certainly shouldn’t be confined by them. If there’s a product that does something better than Blackboard, (or Moodle for that matter) and we can resource it, and it’s universally accessible, (as far as that’s possible with any technology) then we shouldn’t discourage anyone from using it.

Staff Details page in Blackboard 9.1

Seems I’ve let my description of the functionality of Blackboard 9.1 slip a little bit. (Well, we’re waiting for a decision from the Infrastructure committee, on whether we can go ahead with the upgrade this year, and I am quite busy with other things. That’s my excuse anyway).

Nevertheless, Blackboard 9 won’t go away, and I have been asked to demonstrate it for a committee this afternoon, so I thought it worth adding another bit of “What’s the difference” to the blog. This is actually a very minor thing, but it took me a while to work it out, so it might be useful to record it. I was trying to add a “staff details” page, because I think it’s quite useful to identify staff to students and let them know when we’re available for consultation.

Now, the staff details page has always presented problems for those who use Blackboard less frequently, because it’s a tool page, rather than a content area. That’s a bit unintuitive if you ask me, since it only contains content. However, that’s the way Blackboard have designed it, so we’re stuck with it!

Anyway when I tried to add a tool link, I looked in vain for the “staff details” tool in the drop down list. It’s still there though – they’ve just renamed it “Contacts”, which I suppose is fair enough, since you might want to list an entire class in there, or people who are not staff, but whom students may need to contact. Still, if all you wanted to do was to post a list of staff, you don’t seem to be able to change the header on the page which insists on displaying the word “Contacts”. Of course, it may be that I haven’t found out how to do that yet, but while I’m on this, I would really like the ability to change, or remove the header on modules on the course home page, which again, doesn’t seem to be possible.

Blackboard 9.1 Blogs and Journals

The blog feature has, according to Blackboard  been upgraded in version 9.1, and a new feature, journals, added. It’s not immediately clear what the difference between them is. Blackboard’s own documentation says this

A journal is an on-going reflection or record of events by an individual or set of individuals. A blog is a commentary by an individual or set of individuals that is for public consumption and comment

It seems to me though that “reflection” and “commentary” are subjective terms and it would be perfectly possible to use a blog to comment, and journal for reflection. It appears that it is possible, despite the above to make a blog “public” in the sense that other course users can see it, and it is also possible to make a journal “private”.

“Public” and “private” are also slightly loose terms, since neither a blog or journal can be made available from within Blackboard to the outside world.

More seriously, on the test server, it doesn’t appear to be possible to create an individual blog, that is  a blog which is only visible to the student and his or her instructor. In their documentation, Blackboard do claim that it is possible to do this, so it will be important to confirm that this feature is actually available on the live version should we decide to go ahead.  Journals, it is implied, are semi-public in that they are always visible to all course members, but again the documentation contradicts itself by claiming

Individual journals allow students to record their Course experiences and what they are learning. These thoughts can be a private communication between a student and the instructor, or shared with everyone in the course. Journal entries can be commented on by the author and the instructor. Others are able to read public journals, but they cannot comment on them.

That doesn’t really make a lot of sense since if everyone’s able to read them, I don’t quite how see how the thoughts can be a private communication!

Looking at what I can actually see, the main difference between blogs and journal seems to be one of formatting.  The journal entry has a sort of “torn page” look, which is nice, but as far as I can see, largely pointless. Blackboard also claim that students can decorate their individual blogs with an avatar, which, if they used a photo of themselves might help tutors to recognise their students more quickly. That’s actually something whose value should not be underestimated since I think it is important for tutors to be able to match names to faces quickly.  However, since I couldn’t set up an individual student blog, I couldn’t test this claim either.

So in conclusion, I’m not really in a position to say much about this aspect of the upgrade. It’s nice that Blackboard have seen the importance of reflective spaces for students, and that they are apparently committed to providing them. While this has sounded quite negative it is the case that the version of Blackboard we have on test is (evidently) not fully functional. Furthermore, I haven’t seen noticed any complaints about the blogs/journals on cross sector mailing lists, so my worries here may be unfounded. Of course, that may be because there are better blogging tools, such as WordPress, out there, and no-one is using the Blackboard versions.

Blackboard 9.1 Assignments

Here’s the next instalment in my ongoing review of the functionality of Blackboard 9.1. Today I thought I’d have a look at the assignments feature, since there is a lot of interest in electronic submission of work across the University.

There are some improvements in assignment handling, in  the new version of Blackboard, without, as far as I can see any loss of features, at least not of features that we use.  The biggest change is that instructors now have the ability to set assessments for groups. That means two things. First different groups can be given different assignments, although, technically that can be done in our current version by using the adaptive release tool. More interestingly the instructor can decide whether they would like the students to submit a single piece of work on behalf of the whole group. (Some time saving potential there!). If this approach is taken, the instructor still has the choice of giving each student an individual grade, or awarding the same grade to the whole group. Of course a group can still be set up so that each individual member of the group has to submit an individual piece of work, although, if an instructor chooses to do this,  the option to give a single grade to the whole group is still available . Quite how this would be managed remains to be seen, but the technology will support it.

A nice feature when setting up group assignments is that once a student is assigned to a group, they can’t be assigned accidentally to other groups (their name disappears from the list of potential members). This can be turned off though, if an instructor wishes to have students in more than one group.  Similarly, by default, group assessments are only visible to members of the group.

Another additional feature is the addition of an option to allow multiple submissions, each of which can be graded. While this may seem to create extra work, there is something to be said for asking to see drafts of student work, if only because it can highlight obvious errors early on, and even detect obvious plagiarism. It’s also quite good practice for students to draft, and redraft their work, and this option would seem to provide some incentive for them to do so. There is also a submission history. While students have always been able to add comments to their submission, all these comments are preserved, so instructors can check back to see how far a students work has improved over the course of the assessment process.

There are some changes to the instructors view of a student’s submission, as illustrated here.

Instructors view of the student grade page
Instructors view of the student grade page

This appears to be cosmetic, in that the long page offered by version 8, has been replaced by a neater, tabbed appearance, each tab linking to different parts of the page.  There are also buttons each of which links to an activity that the instructor may want to do, such as actually mark the work.  Blackboard are also promising a feature which will allow instructors to mark work online, (that is, without needing to print it out)  and although they have demonstrated it to user groups,  this feature  is not available for the moment.

Conference Report 2: Blackboard Roadmap and upgrade

A second and rather belated report from the Durham Blackboard User Group performance. (Somewhat embarassingly, I’ve lost the notes I made, so this is largely based on the Twitter feed from the conference. Apologies to speakers if I’ve missed anything out. )

The first session of day 2 was the annual session from Blackboard, telling us about their “road map”. This always starts with Blackboard’s representatives telling us what the company has been doing and about their corporate structure. If I’m honest, this bit usually loses me quite early on, and the reason for that, I think is because they need to talk about all their products. For a start Blackboard comes in a number of “flavours”, or, if you want to get technical, “platforms”.

These are

  • Blackboard Classic (which is what we have)
  • Web CT, Vista & CE
  • Xythos, (EDMs and DL)
  • Wimba
  • Transact

I suspect I’m losing you already!  The reason I mention this at all is because it’s a situation that has arisen because Blackboard tend to buy lots of other technology companies, and thus have to cater for the customers of those companies while they change the product.  In the long term, these offerings merge into the various Blackboard products. Currently there are five major Brands

  • Learn
  • Content
  • Community
  • Collaborate
  • Mobile

Just for interest, at Lincoln we have the first three of these. “Learn” is the platform for the sites, that most people use, Community supports the Communities and Portfolio tools, and Content, predictably enough, is the basis for the “Content store”. Strictly speaking Collaborate has not yet been released,  but essentially it is a development from Blackboard’s recent acquisition of Elluminate and Wimba, companies that provide software which offers desk based video conferencing, webinars, and other technology based communication facilities. The idea is to use all five products to offer very large scale deployments of Blackboard. We were given the example of Colombia where Blackboard is used to conduct a National Rural Workforce Training programme, with 2.9 million users, and also, I would think, a very busy help desk.  The sub text seemed to me that Blackboard as a company were going very much for the whole learning experience market. Certainly the Mobile product which comes in two flavours, “Mobile Learn” and “Mobile Central” seemed to support this. “Central” was clearly aimed at pushing university announcements out to students’ mobile devices for example, although I doubt that this would be sufficient. They seemed to acknowledge this by stressing their commitment to Collaborate. (The product, not the activity).  The ability to deliver teaching over the web, and via mobile devices might have been helpful during the recent snow, and we were given a demonstration of how Tulane University had managed to retain 87% of its students after Hurricane Katrina had flooded its server rooms and forced the campus to close for a whole semester. It did this through using Elluminate and assorted mobile technologies to deliver teaching.

Frankly, extreme weather conditions are not that common, at least not in Lincolnshire, so I remain a bit sceptical about this kind of marketing approach. (Why would we buy something we’d only use once a year?)  Nevertheless, we do offer extensive distance learning facilities, particularly at Holbeach, so it may be worth considering. Also, given the likely squeeze on funding for teaching, there may be an additional opportunity for us to exploit these technologies, by, for example, offering reduced fee short courses for distance learners, although clearly such an approach would need a careful cost benefit analysis.

I’m going to skip over the second keynote, (I’ll blog about that next) and move to the afternoon session which is where the user group members get to give the Blackboard team something of a grilling. This is of particular relevance to us, because the question of whether we should upgrade to the next version of Blackboard has become quite important. Last year, there were so many complaints about the new version (version 9.1 for number fans!) that, apparently, the session became known as the “Durham Incident” in Blackboard company circles, and the issues raised went right to the top of the company. The feeling this year was that many of the issues had been addressed. A show of hands showed that about half the delegates had already upgraded, and nearly all of the others were either planning to do so next summer, or were giving it very serious consideration.  We fall into the last category by the way, and if anyone at Lincoln wants to know about, or see a demonstration of version 9.1, please let me know. It should be said that one or two people felt there was still an issue about copying sites in 9.1, which had yet to be resolved, but overall, the feeling was very positive.  Which proved quite a good note on which to end the conference, and does illustrate the value of a powerful and engaged user group for any learning technology company!

Conference Report 1: Augmented reality

This was my fourth visit to this annual conference, which is always held at Durham University. (Because it’s organised by Durham’s Blackboard team, who always do a fantastic job). I have presented a paper here before but this time, I was actually co-presenting one of the sessions with a colleague, Esther Penney from Holbeach, but more about that in another post. First a bit of scene setting. There’s always a theme for these conferences, and this years was “Location Location Location”. The rationale was that if you can’t get to the conference, then we (the conference organisers) have excluded you. The conventional model of a conference, like that of a classroom doesn’t allow for a great deal of flexibility, at least not in geographical terms. But, we shouldn’t get too hung up on location as physical proximity (or lack of the same either). Geographers are finding that people don’t always visit places because they happen to be near them. There may be all sorts of reasons for that which are more social and practical. (Consider how long you’ve been at the university, and consider which buildings, on your campus, you’ve never been in. I’ll bet there’s at least one.
What I propose to do then, is rather than write a long account of all the sessions I attended, is to do single posts about each of the sessions – at least those I found the most interesting/

So, to the first keynote speaker. This was Carl Smith from the Learning Technology Research Institute, whose interest was in exploring the relationship between context and knowledge formation. He did this through looking at what he called “Augmented reality” and he offered some fascinating demos. Perhaps the most conventional of these was a headset worn by a mechanic, that demonstrated which parts of the car engine needed to be dismantled (by highlighting the parts in colour on a virtual display and explaining where the various screws and fastenings were. The point was that the mechanic could switch between the virtual and the real world as the process was worked through. The second demo was a CGI rendering of a seventeenth century steelworks which brought the process to life (and Carl had inserted himself as one of the workers, just for a bit of fun.) These kind of things are engaging, and can be accessed from anywhere, but they lack a mechanism for drilling into the dataset to explore the evidence that the model is built upon.

The real power of augmented reality allows us to augment our vision (no kidding!) However it really is quite powerful. Carl showed a video of man watching an image of the back of his head projected 3 feet in front. The researcher, brought a hammer down hard on the illusion. – That is the point in space where the man in the headset could see himself. The man in the headset flinched violently (and clearly involuntarily) as he saw the projection being hit. He evidently expected to feel the hammer hitting his “real” head. The point was that  consciousness can be convinced it is elsewhere than the physical body. Even into another body. (By placing the headset over a second person’s head).  The point is that it may be easier to switch  locations than we think. From a learning point of view, the question becomes one of how to plan for this escape from a fixed, fragmented point of view? Imagine a real time version of Google Street View. What will change for learning when everything is recorded, and everything is available?

Carl also highlighted the ability of many devices to take a “point cloud” image of people’s faces. This has an obvious application for facial recognition, but it can do more. It is theoretically possible to can take a 3D scan of a bit of the real world, so we can take a 3D scan of our friends, rather than just a 2-D picture, although I suspect this technology is some way from the mainstream yet. On interesting pedagogical application is in the creation of Mediascapes. These overlay digital interactions onto real world. E.g. Google maps can be toured and users given links to images or other digital resources – So you stand in a street and see a film of the same street from some past era displayed on your iPod or iPad)  Effectively that’s a form of time travel for history students, although I don’t think 3D imagery is strictly necessary. That’s nice, but the real power is to drill down to the tiniest part. We saw some quite spectacular examples of architectural details in the ruined Cistercian Abbeys in Yorkshire, which had been recreated in 3D. The user can then home in on some tiny detail and get a history of it. Another application might be to tag a real world item with a QR code, which directs the user to URL, linking to learning materials about the object.

The session concluded with the idea of using your own body as a storage device. To be quite honest, I wasn’t quite sure how that would work, (although I often feel that I could use an extra memory card implanted somewhere!), and on the rather messianic note that Man would no longer need documentation if he were assimilated into an omniscient being – as with God himself. Which is a quote from the 1930’s, suggesting that these ideas have been around for quite some time, even if the technology hasn’t.  Well, to coin a phrase “It is now!”.

Blackboard 9.1 Announcements (And a bit about adaptive release)

Here’s my latest post in the series describing the changes in the next version of Blackboard. (If you want to see others, simply click Blackboard 9 in the tag cloud on the right (or the link at the bottom of the post) and it’ll bring all the posts on the subject together.)

There have been some changes to the announcement features in Blackboard 9.1.  The main change is that Email notifications no longer contain the full body of the announcement text, but simply offer a link to the announcement. This means that users will now have to log into Blackboard to read the announcement. Blackboard have also removed the announcement date filter because they were getting feedback that students were missing important announcements because they didn’t log in until after the announcement had been filtered (In our current version announcements are shown for 7 days after they are made, and after that, if a student wishes to see them, they have to click the “announcements in the last 30 days” tab.)

On the plus side, announcements can now be displayed in courses, the front page, and  on a special course specific announcement module – so students can choose to have a module on their front pages that displays only announcements from a specific course.

Perhaps more usefully, instructors can now set the order in which announcements are displayed, thus removing the need for “permanent” announcements to be used to display an announcement first,  although it will still be possible to use permanent announcements.

Adaptive release will not change significantly,  although it will be possible to notify students when a particular item becomes available (for example, after a given date), and you won’t need to click to confirm quite so many times when you’re creating an adaptive release rule.  As with many features in Blackboard 9.1, you can access the controls from a link to a drop down menu adjacent to the title. (When you’re in Edit mode)

Blackboard 9.1 and Accessibility

While I’m on the subject of Blackboard 9.1 I promised I’d continue to blog about the issues around upgrading. One of the most significant issues that faces any on-line provision is whether it’s accessible, and I thought I’d have a look at what version 9.1 has to offer here.

Blackboard’s upgrade manual has this to say:-

“Most of what makes Blackboard Learn so easy to use for all users, including those with assistive technologies, in under the covers with a combination of CSS (Cascading Style Sheets) and semantic markup (That is, well formed HTML). Additional accessibility features include..

  • Keyboard Accessible re-ordering. (So you can drag and drop content without using a mouse).
  • Personal Styles accepted (So you can change font styles and other elements in their browser, regardless of a style sheet)

So I thought I’d try and test this. Well, you can certainly change personal styles (here’s a picture of the mess I made!)

Accessible version of Blackboard 9.1
Blackboard 9 with Browser Accessibility tools applied

But the point is, that all of this rather lurid colour scheme was done through the browser’s accessibility settings not through Blackboard itself. (There is an option to use Blackboard’s styles, but that didn’t appear to have any effect when I tried it. Do you have to add your own CSS to the local installation?)  I suppose it doesn’t override them, which is a good thing, but I certainly couldn’t get the keyboard accessible re-ordering to work. That may be due to my admittedly lamentable ignorance of using assistive technologies, but it didn’t seem all that intuitive to me. Nor could I work out how to get the context sensitive help to appear.

Having said that I was able to log in, and navigate to a course without using the mouse, so there is some progress there. But that was about all I could do. (For instance, I got hopelessly lost trying to upload stuff to a site)  I think the real challenge for us is to get somebody with more experience of using assistive technologies to give it a better road test than I am able to.
