Electronic exams in the Finnish universities

Verkkotentti

The Finnish Virtual University organized an online seminar on the 9th of December 2009 about taking exams using computers instead of plain ol’ pen & paper. The potential benefits are obvious: students can choose more freely when (and possibly where) to take the exam, and the teacher doesn’t have to worry about finding the suitable time and space to organize an exam. Four speakers from different universities told us about their solutions in this area during a two-hour Adobe Connect Pro meeting, so attending the conference didn’t require a lot of travelling and it worked surprisingly well.

From the presentations it became obvious that there are really two different philosophies of doing exams electronically:

First, there is the more traditional exam type where the student can book a time slot according to his needs, and then go to the space which has been setup as a dedicated exam environment with a computer shut off from the regular internet and a remote surveillance system (usually a video camera and a microphone recording the student). Even staff or students can be around monitoring the process, providing extra security to discourage cheating. These exams can be just like regular exams where you (usually) aren’t allowed any materials and must know all the details by heart.

Second, there is the completely do-it-anywhere-virtual-exam, where the student can use any online computer to take the test, even from the comfort of ones home if he or she so wants. This usually means that cheating cannot be monitored in any secure way and so the exam itself must be of a different type: learning materials are allowed but the questions are broad in scope and require knowledge that you simply haven’t got the time to learn in the time it takes to complete the exam.

The differences between these two ways of thinking about e-tests are interesting and the exam culture probably depends a lot on the subject being taught/learned, so it was interesting to hear about the different approaches chosen.

The aquarium approach

Three universities had built an “electronic aquarium” -type solution, of which two – the University of Jyväskylä (UJ) and Lappeenranta University of Technology (LUT) – had a solution based on the SoftTutor application. LUT had an aquarium in their library building, with 10 machines (seats) and 4 cameras monitoring the place, as well as some paid students on monitoring duty. About 30 teachers are taking advantage of the system at the University, especially for the “maturity test” (fin. kypsyysnäyte, a small exam that tests the student’s knowledge of his/her thesis).

Jyväskylä has a similar solution, with 12 seats and 6 drawing tablets, enabling some sort of free hand drawing to be added to the the exam. 8 courses and 7 teachers were using this electronic exam system as a compliment to the normal exams.  The University of Helsinki has a few different approaches to electronic exams, of which the oldest has been the aquarium system called “Tenttiakvaario”, which is currently in use on the Viikki Campus (3 seats) and at the Faculty of Law and Order… awww, ok, just the Faculty of Law (1 seat), so this is a smaller scale solution that students and teachers nevertheless have been happy with.

The more Out-of-the-box approach

At Tampere the University has taken the course management system Moodle and uses its quiz module for making exams, with the goal of having large groups of students taking the exams in a short time period. Electronic exams have been seen as being especially helpful with organizing book exams, that students need to take sporadically.  Using existing computer classes especially the summer exams have been popular – during the summer of ’09 927 exams were taken.  The exams were monitored, as with the previous examples, using access control cards, video surveillance and spot checks.

At the University of Helsinki Moodle has also been thought of as a way to make remote exams, and then of course the exams themselves have to be re-thought because surveillance is next to impossible to organize.  For example, exams then have to be more “putting knowledge in practice”-type broad questions than questions asking for detailed tidbits of knowledge. This approach could in the future mean great savings to space costs if people could do exams on their home computers instead of being dependent on expensive computer classes. And space costs are always an issue in Helsinki.

It was nice to hear these stories, and I think electronic ways of taking exams – or really any new way of grading & monitoring learning – could be helpful, but maybe the biggest challenge then is to embrace the new possibilities instead of trying to fit the old ways into new technology. It is an frustrating idea that you have all that processing power and networked knowledge at your fingertips, but you’re only allowed to write text in a Word document during the exam.

Edit – forgot the music to this post, here it is – a soothing piano piece (no video) by Eluvium, the album Copia is really great!

E-reader: first impressions

Sony Reader PRS-505Having recently acquired the Sony Reader PRS-505 [trustedreviews.com] courtesy of a friendly New York -bound vet (thanks Elise!), I’ve now read a couple of books on this device utilizing an “electronic paper” -type display a.k.a. E-ink [wikipedia.org] and am ready to give my first impressions of it. “So why yet another gadget, Kristian? Can’t you read text from your computer display? What about the feeling of REAL books, books that look good on your shelf?” you might be asking, but despite flat panel LCD:s being quite OK to read from nowadays, they’re still not a match for traditional ink on paper when it comes to readability. With physical books, shelf space is always running out and frankly, some of the sci-fi stuff I read, the books generally have embarassing covers… 😉

Two good reasons for one more gadget 

Electronic paper, which has been touted since the 1970’s is now finally becoming mature enough for consumer products, and here are THE two good reasons why this is a worthwile technology:

  1. Particles in the electronic paper display switch physical states and create an effect that is very similar to ink on paper which is easy on the eyes, has minimal glare and comes without an annoying backlight behind the screen (so you actually need the bedside lamp switched on just like you need with a traditional book)
  2. Once the text/picture has formed on the display, it does not need to be refreshed (or backlit) thus using much less power than traditional display technologies. One charge on the device is sufficient for months of reading (or, a month at least during my first trial)

These two factors are the significantly important (p < 0.05) things that an e-reader offers compared to other devices. The reading experience and energy consumption, folks. Oh, and the fact that you can cram hundreds of books in the built-in memory and on external memory cards making it the ultimate portable library. Limitations there are as well, alas, current e-book readers are black & white only (8 levels of greyscale in this case) and refresh times are much slower than with traditional displays, meaning there is a flickering lag (slightly less than a second) when you refresh the display with another page. So don’t plan on watching movies on these things.

Impressions after the first book

The device itself is a nice, slim design – the reader looks good (= your coolness factor goes up when you whip it out in public, always important) and feels solid thanks to its metal casing, and it comes attached to a faux-leather “book cover” which nicely protects the screen as well. It is clear within seconds to probably anyone that reading text on e-paper is much nicer than reading from a laptop or mobile phone screen. The contrast is good and while it’s more like reading a laser printer draft on slightly ashen paper (“…a bit of volcano fallout in the air today?”), it still beats any other screen I’ve tried when it comes to replacing real paper. And because of the way the reader works, you don’t have to think about powering the device off when you take a break from reading, just throw – or, rather, gently place, these things are still a *lot* more fragile than paperbacks – the reader on the bedside or in your bag and think nothing about it. Convenient.

A pleasant surprise is the multitude of (open) formats supported, which is untypical of Sony. The Amazon Kindle [wikipedia.org], for example, is quite married with its own e-book format (and US customers currently), whereas the Sony reader can read several common formats, including the “new standard”, EPUB [openbook.org]. It supports PDF’s as well, but these (esp. big files) are still problematic for the small reader screen; zooming in on text doesn’t work that well and you really need to convert the PDF to a reader-friendly format first for best effect. This is something I will try out more later, however.

Generally speaking, reading with the device went well, I was not annoyed by the flicker/pause when flipping a page and the user interface works fine. The buttons for switching pages aren’t perhaps optimally placed for my tastes, a small quibble.

Oh, and the first book I read? Here.

Who is it for, really?

Despite its stylish looks, this e-book reader is clearly still early technology – it feels a bit like riding a steam engine locomotive when you can already see maglev trains on the horizon. But when e-paper devices become cheaper, tougher, more versatile (they can be made flexible [readius.com], for example) and display colour I do feel like this will be a great way for researchers and students to carry articles and course books with them in a portable fashion. And traditional newspapers could benefit from e-paper as well [businessinsider.com]. Already the more expensive e-book readers come with touch screens enabling comments in handwriting or drawing on the e-paper and similar stuff, thus bringing them closer to normal computers than simply passive reading devices.

The PDF-support is not there yet, however, and the relative sluggishness of the displays makes flipping through pages not quite as smooth an experience as it should be, so in current form I suspect these devices aren’t yet the portable article repositories academics would like to have but wait a few years… so if you’re thinking about downloading the latest research papers on the reader for a quick browse, forget about it.

Another thing is the cost of content and possible DRM restrictions on e-books – prices for commercial books are still too high compared to the paper versions, so I don’t know how many books I actually will purchase for this system. Maybe I’ll read all the free classics I can get first, but it would be really nice to read contemporary content as well.

Currently the e-book readers (at least the one tested) are very good for people who read a lot of novels – as the price is high, you’ll need to read a lot to justify the cost compared to traditional books. But reading from a dedicated e-book reader is just that much better than any other digital solution, so it’s worth trying out!
