YouTube: Statistical Goodness


YouTube Viewing Stats

Call it a means to fuel (or decimate) the ego, to better target a demographic or market niche, or merely an interesting tidbit of numerical information, YouTube’s launch today of a detailed statistics tool has given users a great deal of insight into where their clips fit amongst the video viewing masses.

Via Official Google Blog (”Insight into YouTube videos“, 26 March 2008):

“…uploaders an see how often their videos are viewed in different geographic regions, as well as how popular they are relative to all videos in that market over a given period of time. You can also delve deeper into the lifecycle of your videos, like how long it takes for a video to become popular, and what happens to video views as popularity peaks.  For now, you can find currently available metrics by clicking under the “About this Video” button under My account > Videos, Favorites, Playlists > Manage my Videos.”

From a learning and teaching standpoint, with educators increasingly turning to YouTube and other online video streaming services as ways to not just locate content, but share their own, these statistics could provide valuable insight into the minds of their students.  For example, educators might determine which subjects students found the most interesting versus the least, compare like topics over the course of several sessions, or determine trends in study habits.

In an ideal world, viewing statistics might even be combined with qualitative feedback gathered via user comments, classroom discussion and student evaluations to provide examples of teaching quality that could be fed into promotional criteria.

Educational use of streaming video in such a public sense is still relatively new however, so it will be interesting to see what real use cases emerge from online video streaming services like YouTube.

On a personal note, I’m not nearly popular enough on YouTube to derive tremendous benefit from this tool, but I do find it interesting to see that my viewers originate primarily from the United States and Western Europe.

As testimony to my uncoolness, on the Popularity Scale where 100 represents the top clip in the region and 0 is…well…not, my rating is 0.35.

Guess I won’t be quitting my day job any time soon…

“Do I even need a traditional blog?”: Expediency vs. Exposition


One of the people I follow on Twitter, (jeff)isageek, asked the question today: “With services like friendfeed, twitter, disqus, google reader, del.icio.us, etc [sic] do i even need a ‘traditional’ blog?

From the standpoint of eLearning and educational technology, my answer is a resounding: Yes.

Sure, it’s important to evaluate new technologies in terms of how they can be used to embetter our online activities - and more importantly our offline activities - however this must be ever tempered by proper investigation and inquiry.  Immediately flocking to the next new trend without thoroughly investigating the last one is detrimental to all technologies involved; not to mention the people that use them.  This is especially critical for education.

New technologies are emerging at a phenomenal pace, and perhaps not surprisingly this has served to whip up an ever-present sense of excitement and anticipation in which people are constantly looking for the next great innovation to top the last one.  In some regards this is a very valuable trend for the industry, because passion and enthusiasm breed interest and uptake, and people who may have once ignored the possibilities offered by eLearning and web technologies may perhaps begin to consider them.

In the same breath though the danger in this is that users may afford new tools an overinflated sense of value fanned by the flames of media hype.  The important task for users therefore - and particularly for educators - is to ensure these technologies are evaluated and analysed according to their own merit, rather than the ever fickle waves of pop culture influence; lest we fall prey to the curse of implementing technology for technologies sake.

In the case of brand new so-called lifestreaming technologies, advocates seem to place a tremdous amount of value on the speed of use and real-time interaction they afford users.  Ideas that were once allocated several hundred words are now crammed into 140 characters.  Speed is being afforded more consideration than thorough contextual elaboration.

This is what blogs facilitate that technologies like Twitter and Friendfeed cannot.  They provide space for carefully considered contemplation and reflection in which time requirements are secondary (if that) and accuracy and thoroughness of information and thought are of the utmost importance.  In keeping with this the comments and discussion that take place on blogs facilitate more considered responses, and are often times vehicles for investigation and reflection in their own right.

For certain industries, or social spheres, blogs may be quaint and passe; but they are not, and should not be perceived as such for education.

This is not to say that the aforementioned “friendfeed, twitter, disqus, google reader, [and] del.icio.us” do not or may not serve valuable purposes.  Real time communication tools, RSS readers and feed aggregators, social bookmarking tools, and discussion tools all have their uses - in fact they can be incredibly valuable.  The importance is to allow sufficient time to realise their true value (or lack thereof) before discarding older technologies.

The point: By all means, try everything; but evaluate them properly and thoroughly.  And remember, ‘traditional’ doesn’t always mean obsolete.

Dual Booting Ubuntu Hardy Heron with Windows


Target Audience: This guide is intended for PC users new to Linux and outlines an easy way to configure an existing Windows machine to run Ubuntu 8.04 “Hardy Heron” in parallel.  It is acknowledge this may not be “dual-booting” in the true sense of the word, however from the standpoint of a new user it is considered comparable. 

———————–

I’ve spent a great deal of time in Ubuntu lately, during which time I’ve discovered a really cool new feature in the Hardy Heron beta (v 8.04).  As ZDNet reported earlier this week (”Ubuntu 8.04 “Hardy Heron” beta - making life easier for Windows users“), Hardy Heron now supports seriously easy parallel installations with Windows.

Dual booting systems is not a new trend of course.  It just means you’re able to run two different operating systems off a single box. However this can be very useful in that it expands your computational landscape - particularly from the standpoint of running platform-specific/niche software or application testing and troubleshooting.

Historically however the installation process for dual-booting machines has been so involved as to make it prohibitive to many users.

What Hardy Heron has done is facilitate the set-up using a wizard process, which dramatically lowers the obstacles to uptake for new users.  Realistically this is an obvious ploy to draw Windows users away from the PC; however from my perspective it is a welcome one.

As the ZDNet article says, Ubuntu’s wizard process is a snap; the most complicated aspect is configuring your machine to work with the ISO image that contains the installation files.

NB: This concept of an ISO file is not Linux-specific; it’s just a self-contained image that contains all the information you need to complete the installation.  ISO files normally come on a CD and are mounted by inserting the disc into the disc drive.  In this case we need to set the machine up to treat the ISO image like it does a CD or DVD.

Ingredients:

As with most operating systems, the Ubuntu installation files are a decent size - roughly 650 megabytes.  So the download process can take some time to complete.  Alternatively you can request that Canonical send you a copy of the software - which they do for free, believe it or not.

In the meantime you’ll need to configure your machine to work with the ISO file.  There are an assortment of free programs available you can use; I used the free one provided by Microsoft.

Mounting the ISO file

  1. Download the ZIP file and extract it to a folder you can easily find.
  2. Copy the VCdRom system file and place it with the other system drivers - on my machine this was located at C:/Windows/system32/drivers/
  3. Open the VCdControlTool application and click Driver Control - you will receive a message saying something to the effect of “the driver was not found.”
  4. Click Install Driver. Browse to the file you just placed in …/system32/drivers and then click Start, followed by OK.
  5. Now it’s time to mount the ISO file.  Click Add Drive.  An available drive letter will be displayed.  Select the drive letter and click Mount and browse to the location of the ISO file. NB: I recommend ticking “persistent mount” at this point.  That way if you have to restart your machine you won’t have to remount the image again and can just eject/dismount it when the installation process is complete.
  6. Go to Windows Explorer or My Computer and you will now see the Ubuntu installation “disc” available.  Double click on that to begin the installation process.

At this point you can follow the Ubuntu installation wizard processes outlined in the ZDNet article.  As I said though, the wizard process is exceptionally straightforward; so you may not even need the guide.   Just make sure you select “Install inside Windows” if you want to have access to both operating systems.

Please note: I was unable to install Ubuntu on a different drive - it seems to only work when installed on the same drive as your Windows installation.  I made it to the end of the installation process only to be told I couldn’t start Ubuntu.  This didn’t affect the existing version of Windows mind you, but it did eat up half an hour.

Logging into Ubuntu

Now that you have two different operating systems on your machine you will be prompted to select which one you wish to use every time you start the computer.  By default Windows is selected, and after 15 seconds it loads automatically.  If you want to boot into Ubuntu just use the down arrow of your keyboard to select Ubuntu and click Enter.  Ubuntu will then load and off you go.

Uninstalling Ubuntu

The hiccups I experienced when attempting to install Ubuntu on a drive other than C:/ gave me the opportunity to test the uninstall tool, which once again is very straightforward.  The Ubuntu installation is placed in the root of the drive in a folder called “ubuntu”.  To uninstall Ubuntu, login to Windows and navigate to the uninstall file through Windows Explorer.  Click on it and you’ll be asked to confirm the uninstall process.  You’ll also be given the option to save the ISO file.

I recommend you save a copy of the ISO file in case you want to try Ubuntu again in the future.  This will save you from having to download another 650 megabytes later.

A word of caution here though, I ran into trouble when I left the archived ISO file on my E:/ drive and tried to re-install Ubuntu on the C:/ drive, where the Windows software is located.  (At this point I had two copies of the same ISO file, only one of which was mounted.)  For some reason the installation process kept trying to reference the image on the E:/ drive.  When I deleted the 2nd ISO file I was able to complete the installation successfully.

Just Add Wine: Running PC Software on Ubuntu


Adobe Photoshop on LinuxAs I mentioned yesterday, I am regularly across several different operating systems over the course of the average day.  Typically this includes Mac OS 10.4 (Panther), Windows XP Professional and Ubuntu Linux Gutsy Gibbon.

Recently however I’ve begun to think in earnest about ways to streamline my computational activities - and particularly to shed my reliance on proprietary software, most noteably Windows/Microsoft.

At the end of the day though the thought had always lingered that I’d have to maintain at least a minimal presence in Windows - like it or not. One of the main criticisms I hear regarding open source is fact many of the industry standard programs for PC do not support Linux.  So how then, the logic would go, could you manage a completely break from Windows?

My research so far has revealed some very promising results that seem to suggest that Microsoft does not have as tight a grip on me as I’d previously suspected.  I’ve just confirmed - as is depicted by this screen shot - that you can successfully install and run Photoshop on Ubuntu via a largely open source and completely legal process.

The Installation Process

The process involves three stages, and the inclusion of a program called Wine.

Via Wine HQ:

“Wine is a translation layer (a program loader) capable of running Windows applications on Linux and other POSIX compatible operating systems. Windows programs running in Wine act as native programs would, running without the performance or memory usage penalties of an emulator, with a similar look and feel to other applications on your desktop.”

Ingredients:

  • Ubuntu Linux (I used the Fiesty Fawn version)
  • Wine
  • A licensed copy of Adobe Photoshop

Setup Procedure

Phase One: Install Wine

From the Wine HQ site (”Wine for Debian based distributions“):

“First, open a terminal window. Then add the repository’s key to your system’s list of trusted APT keys by copy and pasting the following:

wget -q http://wine.budgetdedicated.com/apt/387EE263.gpg -O- | sudo apt-key add -

Next, add the repository to your system’s list of APT sources.  The proper syntax will depend on your version of Ubuntu, so be sure to check the website for details.  In my case I use Fiesty Fawn, and entered the following in the terminal window:

sudo wget http://wine.budgetdedicated.com/apt/sources.list.d/feisty.list -O /etc/apt/sources.list.d/winehq.list

When this process is complete, run: “sudo apt-get update” followed by “sudo apt-get install wine“.

Providing all has gone well you’ve just finished the first phase of the process.

Phase Two: Install Photoshop

Once the Photoshop installation process begins, the steps will look quite familiar to Windows users.  Prior to this you have to instruct the system to run the installation within Wine.  To do this open a terminal window and type wine followed by the pathing to the setup.exe file.

For example:

wine /media/ISO/setup.exe

At this point, Wine should take over and begin the native Photoshop installation process.  From here it’s just a matter of following the standard installation procedure.

Photoshop FolderPhase Three: Finalise the Setting Configuration

When the native Photoshop set-up is complete you’re just about done.  There are only one or two more steps to complete.

As The Pinoy Geek explains (”HowTo: Install Photoshop in Ubuntu“):

“After the installation has completed, you may now run Photoshop under wine! Go to Nautilus (the Windows Explorer counterpart of Ubuntu, Places->Home Folder). Here, the default setting is to hide Hidden files, but we don’t want this because Wine installs applications under a hidden directory. So let’s tell Ubuntu to show us the hidden files by toggling it under the “view” menu.

View->Show Hidden Files, or simply press [CTRL]+[H].

Some other folders should appear now, look for the folder “.wine” (yes, with a ‘.’ preceding it) and double-click it. Now, enter the folder “drive_c”. The directory structure should be familiar from Windows. You should now locate the “Program Files” directory, then the “Adobe” directory, and lastly, your Photoshop directory. Once you’ve found it, simply double click Photoshop.exe and let Wine do it’s magic.

Final notes: If installation or running the program under Wine doesn’t work, try configuring the Wine to run under “Windows 2000″ mode. To do this, go to the terminal and type:”

Photoshop in Applications Drill DownNB: At this stage you should be able to run Photoshop.  Personally I found the system hiccuped a bit initially, but this was resolved by a restart.  After the restart things settled down and I had no problems opening or using Photoshop.  I also discovered a new option called Wine had appeared in the Applications list.

Final Thoughts

These preliminary findings are extremely positive ones indeed, and portray Wine as an invaluable vehicle through which PC users can make the switch to open source operating systems.  Moreover, a cursory glance of the Wine Application Database suggests further opportunities for running additional proprietary sofware above and beyond Adobe Photoshop; and we haven’t even begun to discuss the pool of open source software that can be run natively within Linux.

I will be experimenting with Wine as time goes by and will provide updates when there is more to report.

Screw you guys, I’m going home!


I’m seeing a disturbing trend coming out of Mac-land right now, and it’s starting to piss me off.

As I mentioned yesterday, the slimy push to get Safari installed on PCs via the Apple Software update is poor form, but in and of itself it’s just irritating.  The motives that drove the decision on the other-hand are more disconcerting; but what makes me really angry is the arguments in support of the move coming out of the Mac-head camp.

In a comment on Paul Mison’s post “A Translation of “Apple’s Windows Invasion“, Tom Insam writes:

“Obviously Apple realised that if they wanted to get accepted by all those windows users, they had to install irritating system tray icons and background processes and intrusive update software like everyone else. Not to mention apps with their own look-and-feel that don’t look like anything else on the desktop. It’s just Apple trying to fit in on the platform.”

This argument is pathetic and echoes of school-yard me-toism, where the only logic is “Everyone else is doing it.  Why not us?”It reeks of an application that lacks the appeal and quality to be adopted on its own merit and therefore can only get into the user radar through underhanded tactics.  It reflects very poorly on Safari, as is being demonstrated by the outrage across the web as we speak.

If Steve Jobs was trying to gain the ear of PC users this way, it hasn’t worked.  The move is being seen for what it is: a desperate ploy for attention.

But to be fair, as has been explained elsewhere, this tactic is nothing new. Apple hasn’t sunk to depths unexplored by other companies.  They’ve just joined their ranks.

Let’s get this straight, Apple: This tactic is unacceptable no matter who does it.  This goes for Google, Yahoo, Microsoft, and Apple.

From my standpoint as a consumer, this has broke my trust, my confidence in the company and eliminated any desire at all to use the browser.  I choose to use an application; it cannot be forced on me.  And the fact it is being forced on me means I will never use Safari by choice.

I am not a zealous PC-user either.  My laptop is a MacBook which has virtual installations of Windows XP Professional and Ubuntu Linux Gutsy Gibbon.  I see computer software as a tool through which I can achieve the aims and objectives I set for myself.  I do not see the borders of operating system or program that some people get hung up on.  If it serves the purposes I need it to, I’ll use it.

However when I see companies like Microsoft, Google, and Apple breaking my trust it alienates me - immediately.  I used to love Google but have begun to shy away from them; I used to trust Microsoft, but have done the same.  Now I do the same with Apple.

I’ve developed quite an appreciation for open source philosophies, and the freedom, choice, and openness they advocate.  Apple’s move with Safari has reminded me of what I don’t want to return to with proprietary companies.

Slimy tactics won’t earn Apple any more Safari users


Safari Install Prompt in Apple Software UpdateHere’s the story I keep expecting to go away, but instead it keeps growing bigger and more controversial by the minute.

Apple has recently begun to use and/or abuse their extraordinary share of the media player market held by iTunes as a jumping off point for spreading the uptake their Safari browser.  This has many PC users seriously miffed, and appears to have fanned the flames of the long-standing operating system war between Mac-heads and PC-users, which has been burning since the 1980s.

When installing iTunes, users are also required to install the Apple Software Update tool, which regularly checks for new versions of the software.  When a new version becomes available, users are prompted to download and install it.

Being prompted for software updates is nothing new.  What is stirring the controversy is Apple’s increasing tendency to use this update to try and piggy-back other applications.

This began with QuickTime, which is so closely integrated with iTunes you cannot install iTunes by itself anymore.  Apple has now expanded this tactic to include prompts to install Safari as well.

The symptom in question appears when you have iTunes but not Safari installed on your PC.  When the update appears, users now see the inclusion of Safari, with the install option selected by default.

While not nearly as bundled as QuickTime, the fact users are now being prompted to install unwanted or unrequested software is getting people’s backs up.  You need only look to the Digg thread on “Apple pushing Safari downloads on Windows users” for examples of the anathema this move is being met with.

More recently though, Mozilla CEO, John Lilly weighed in:

“…by and large, all software makers are trying to get users to trust us on updates, and so the likely behavior here is for users to just click “Install 2 items,” which means that they’ve now installed a completely new piece of software, quite possibly completely unintentionally. Apple has made it incredibly easy — the default, even — for users to install ride along software that they didn’t ask for, and maybe didn’t want. This is wrong, and borders on malware distribution practices.”

I for one find this irritating, but not nearly the personal afront that some people are making it out to be.  As Tom Kranit from CNet discussed yesterday (”Think before you install“), it’s important to pay attention to what you’re doing when you click OK when prompted to install something:

“Had Apple bundled Safari with iTunes, the way they bundle Quicktime, I can see where Windows users would have more of a complaint. Being forced to install something you don’t want just to get updates for something you do want is not cool. You can download standalone versions of QuickTime or iTunes on Apple’s site, but sometimes they appear bundled in Software Update and people don’t realize they have other options.

But that’s not what’s happening with Safari. If you don’t want Safari, don’t click “install.”

It seems that at some point people became conditioned to downloading anything that shows up from an official source, like Microsoft, Apple, AOL, Yahoo, or whoever. Remember, it’s your PC; spend your installation capital wisely.”

I don’t think this move is going to do much to increase Safari’s market share. PC users by and large seem to take their browsers in one of two flavours: Internet Explorer, or something that isn’t Internet Explorer.

In the case of the latter, this title is well and truly held by Firefox; and as far as I’m concerned, Safari just can’t compete with Firefox.  Sure it’s fast, but so is the Firefox 3 Beta 4 version, which I’m using currently. With Safari you’ve got zippo on the customisation options; with Firefox, you’ve got a massive library of tools and add-ons for building your browser experience exactly the way you want it.

So I don’t see Apple gaining very much by this move, except criticism that it’s becoming another Microsoft. These slimy install tactics have just given me another reason to ignore Safari, not embrace it.

Call for feedback - “Bridging the Divide: Facilitating the exploration of emerging technologies that support innovative learning and teaching”


Several weeks ago a series of conversations on Twitter and touched on by edubloggers Kate Olson (”Edmodo - I scored an alpha invite“, Reflection 2.0, 6 March 2008) and Kelly Christopherson (”Go to the source“, Educational Discourse, 7 March 2008) inspired me to sit down and write out a support structure to aid educators interested in exploring the educational uses of emerging technology.

As most of my good ideas seem to do - with or without my consent - the brief framework has since become something vastly larger. It’s become a full-fledged paper in excess of 11 pages.

I feel fairly confident that I’ve captured the essence of the issues Kate and Kelly have talked about, and have hopefully presented something that will prove useful to educators and administrators; but I’d like to open up the paper to comment and feedback to gain an outside perspective on whether it makes sense to the target audience.

I’ve attached the paper as a PDF download at the bottom of this post and would be very grateful for any feedback and suggestions. You can either leave these as comments on this post or email me directly through the contact form on this blog.

Abstract

There is a growing swell of interest across education, with educators seeking to harness the power of emerging technology in ways that enhance learning and teaching. Despite this, educators frequently do not have access to adequate support and consultation to aid them in bringing to fruition their visions for innovative teaching practices.

The primary focal point of this discussion paper is to elaborate on the nature of the growing divide between so-called “users” and “non-users”, propose solutions for bridging the gap, and inspire discussions that seek to identify and resolve this issue.

Importantly, this paper will also discuss the presence of another divide - one between providers of support opportunities, and the developing user community that requires these services. This divide is seen to represent a barrier to uptake and exploration of emerging technology that amplifies the disparity of the primary divide between users and non-users.

Update: I’ve added this document to Scribd, so you know have the option to download it, or read it online.

Flickr video finally?


I normally try not to buy into the rumour mill, but this is a story that just won’t go away. Furthermore, I’m really hoping it proves to be true.

As is being reported by a number of different online tech publications, most notably CNet News.com and TechCrunch, Flickr is allegedly slated to enable video sharing sometime in April.

Via TechCrunch:

“…rumors are flying that Yahoo intends to integrate video into Flickr very soon, perhaps in the next three weeks. Part of the delay may have been a long internal debate about how to make Flickr Video special and distinct from what YouTube already offers. They apparently have come to some product decisions, and will be making an announcement soon.”

It’s not surprising that YouTube is immediately brought into the discussion. With YouTube and online video virtually synonymous these days, how could you not mention them honestly. Yet while there is a fair amount of overlap in the user-bases of both applications, I see some distinct differences that are worth bearing in mind.

For example, depending on how Flickr envisages and implements their video service, support for video downloads could be extremely significant. This is why I’ve always favoured Google Video over YouTube. Google Video offers the option to download Video iPod/Sony PSP instances, whereas no such functionality exists on YouTube. There are of course a whole slew of applications that facilitate this activity - legal or otherwise - but the fact remains there is no native functionality in YouTube.

Whether this is meant to force users to continue to return to the site to imbibe their daily dose of advertisements, curb the spread of illegally uploaded material, or perhaps some other reason is unclear. Regardless, the absence of a download option has always been a huge strike against YouTube for me. I also don’t see how this is a developmental oversight.

Comparing video delivery and photo delivery is like comparing apples and oranges of course, but the fact remains that Flickr makes downloading content very easy. You give the users a suite of different access and download options and let them decide. I see no reason why this should be any different with video.

More significant that that though are the fundamental differences in community mentality that surrounds each application. This is more of a tangential consideration from an application perspective, and yet it’s still quite relevant for users trying to decide which service to use. To me YouTube is geared towards content you want to share with masses of people; Flickr is for more personal content.

YouTube is an arena rock concert, much like Woodstock; Flickr is an intimate acoustic show in a coffee house. The user mentalities are vastly different between the two services.

This more than anything is what Flickr needs to focus on when considering their video service. With Flickr you can still discern a sense of self amongst the user base which could yield some really valuable interaction. With YouTube you see a crowd mentality that can propel a video to millions of hits in a matter of months, but that can also produce some pretty nasty characters.

I don’t upload family material to YouTube for this reason - at least not publicly. With Flickr Video, I’d be more inclined.

Pageflakes as a Blogging Portal


Pageflakes as a blog portalHere’s a quick idea that might prove useful for educators currently using - or thinking about using - blogs in classroom exercises.

One of the challenges of individual student blogs is the fact they’re independent of one another. So by themselves there’s no easy way to keep track of the activity from a single location.

I’ve seen instructors set up a blog to act as an index or portal, where each student blog is referenced with a link and description, or with each student’s blog contributions displayed as an RSS feed in the menu. However both options are still somewhat lacking.

Considering my recent experimentation with Pageflakes I have discovered an alternative that some may find useful. From their About page:

“Pageflakes is the easiest way to discover and share your favorite things on the Web. Whether you are trying to keep your family informed, track the many blogs and news sources that you read daily, promote a small business, or just wanting to express your ideas and interests, Pageflakes provides you everything in pages with your own unique mix.”

Pageflakes is a web-based aggregator for tonnes of different types of content. Users have the ability to select from a huge (and growing) library of different widgets, thereby creating customised pages that contain content from across the web. This can include videos, static text, email tools (for reading, sending and receiving), and importantly displaying RSS feeds.

Importantly, Pageflakes includes a feature known as Pagecasts, which enables you to make your pages visible to others. With Pagecasts you create a page as per normal, select Make Pagecast, and then select a visibility option (private, share with nominated individuals or group, and publish openly). Once configured the the page is visible at the level you have identified.

In the context of classroom blogging projects, this could easily be used as a portal whereby students and staff could browse through the recent contributions. Given the view options include the ability to restrict access to nominated individuals you could also maintain a level of privacy where only classroom participants have access, or open it up as a showcase for what your class is doing.

I’ve created an example I’ve called the “edubloggers aggregate” (see image) which contains the feeds for 12 of the blogs I follow. Personally I find the Pageflakes format much more conducive to browsing than a blog-as-portal. In some ways it even looks like an online magazine.

This was put together fairly quickly too, so with a bit of effort you could make one look even nicer and include information such as project background, blogging assignments, references or resources or other functionality offered by the widget library.

The flexibility offered by Pageflakes is an ideal option for tying an unrelated mass of disparate blogs into one unified portal, which in turn can reinforce the notion that the blogosphere is comprised of people, and not just content.

Commercial Hosting and the Protection of Student Data


Question: “Which blog provider should I use?”
Answer: It’s complicated.

As an individual question in and of itself this is not a very challenging thought; however when you work for a central non-academic unit like I do, and the person asking the question is looking to implement blogs course-wide as a student journal project it is a different situation entirely. The question is no longer a simple one; it has significant implications that need to be considered.

In the event your school or institution has a centralised blog hosting service the answer is easy. It is always ideal to use onsite hosting. It’s when there is no central hosing service that things get complicated.

First and foremost it’s essential to consult your institution’s guidelines and policies before even considering using a commercial/external provider. This is not a decision to be taken lightly, and some schools may have policies strictly forbidding storage of student data off-site. It’s also wise to consult with local subject matter experts and in some cases legal experts - especially with respect to End User Licensing Agreements.

Particularly in the case of EULA’s, as painful and incomprehensible as they can be to read, it is critical to read the fine print to ensure nothing questionable is included that could have an adverse impact on the course, students, data, an your obligations as an instructor. The Terms and Conditions outline what you and your students commit to when you use the service. They include rights and responsibilities for both user and service provider, and importantly Intellectual Property issues. All of which are important to be aware of.

Above and beyond EULA considerations, the key issues of off-site hosting involve student data, student privacy, and security. Institutions and schools have legal obligations to protect and preserve all of them. So the prospect of storing this information off-campus needs to be carefully considered. Policies and laws will vary from country to country, but the fundamental issues are more or less the same.

In the instance of student data, the significance lay in the protection of assessable material and student work. When a homework assignment is submitted, schools have an obligation - moral if not legal as well - to ensure it is kept safe. For locally hosted services this frequently involves sophisticated and expensive servers, disaster recovery equipment and plans, and IT staff to maintain the environments. The IT people I know take this area very seriously, which is the way it needs to be. Just imagine the catastrophic consequences of losing a student’s thesis or dissertation in a server crash.

It’s always wise to instruct students to store back-up copies elsewhere, and not rely on the online environment as their sole storage location; but this concept isn’t always emphasised or adhered to. It should be.

It’s important to bear in mind too that student data not only refers to preservation of the data, but access to it as well. With a common mandate being the preservation of student records for at least a minimum amount of time, it’s critical that any online service be assessed for the long term availabilities of the information they will contain.

Access to information also refers to service up-time. In this sense preservation of student data refers not solely to what has already been created, but what is currently being created, and even what will need to be created in the future. If you give your students an assignment to write a blog post by a certain date for example, but the blog provider suddenly and unexpectedly has an outage, your students are unable to complete their assignment.

This is not to say there aren’t ways to accommodate these unexpected inconveniences, nor that outages are limited to external providers (they unfortunately happen with school-hosted environments too), but rather that they are important considerations to factor into planning.

With student privacy you deal with a student’s personal details - name, student ID number, grades and marks, even address and phone number. All of this information is highly sensitive. Online applications do take the protection of this information very seriously, but schools take it arguably more seriously - especially when the students are minors/under-aged.

Last but not least we have security, and this relates to all other facets of online activity. Without adequate security you cannot have privacy, or ensure that student data is being preserved and protected. You also cannot effectively create a safe and secure online space in which students feel free to expand their horizons and pursue new avenues in their learning processes. Indeed adequate security is crucial to ensuring the moral and legal obligations of the educational institution are adhered to.

All this is not meant to scare you away from the internet, by the way.  After all, the innovations taking place across the World Wide Web provide educators and students with an exceptional amount of potential to design dynamic and engaging learning environments that can truly inspire learning. The flexibility and opportunities in the new web are truly astounding and should be looked towards to enhance and support learning and teaching.

The point is that preservation of student data, privacy and adequate security must take priority above all else. Even the best suited online learning environment should not be used if there is doubt about its abilities to preserve and address these crucial elements.
