We have used eye-tracking in most of our studies in NELL. Some data are really interesting, in other projects we didn’t learn as much. Why is that? Here are some ideas what to watch out for when planning an eye-tracking study.
- Eye-tracking data needs to be combined with other data sources. We found that in many cases the eye-tracking data could be interpreted in a meaningful way only when looking at interview responses of that person at the same time. Unless tasks are short, unambiguous and deterministic, the observed gaze behaviour may have a variety of reasons.
- Eye-tracking helps to improve design. Did users look at that image? How long did it take them to notice the button? What attracted their attention first? These are questions that eye-tracking can answer and that may inform design decisions.
- Eye-tracking may be more effective in later stages of the design process. Once you have a full mock-up quantitative analysis of gaze behaviour, heatmaps, etc. can be very informative. In contrast, wireframes or other early prototypes are probably better evaluated with qualitative feedback. For example, we explored which type of information learners would use when looking for help from a peer. We created three different mock-ups of the PeerFinder component and compared both the eye-tracking results as well as their preferences.
After all, User Experience is really all about selecting the right methods at the right time for the given target group and given tasks. I frequently tell my students that they have to be able to evaluate the strengths and weaknesses of a method in a given situation. Eye-tracking is one of many data collection methods. It may be used in a number of different ways.
This blog gives a good overview of the advantages and disadvantages of eye-tracking: The eye is the mirror to the soul? What does eye-tracking research tell us?

Sebastian Thrun from Udacity probably read my last post on Massive Open Online Courses. At least that could be the motivation behind his latest idea: He aims to teach the largest on-line class ever. I don’t know where the current record stands, but this one will be large for sure. The Intro to Statistics course will start on June 25, 2012 and promises to be an interesting endeavour.
Meanwhile, I have completed the Web Application Engineering course “with highest distinction”, including all homework and final. I loved it! I learnt how to use Google App Engine and Python and created a wiki system with login, editing and history functionality. The instant feedback to submissions makes it easy to see your progress.
So, if you always wanted to learn about stats, this is your opportunity. See you there!

For years and years, one of the main arguments proposed in favour of using learning technologies has been: “It scales!” Whether there are ten, a hundred or a thousand students in your class, it doesn’t matter. We used this argument in the early days, when developing adaptive on-line courses for students at the University of Education in Freiburg. And yes, we had a couple of hundred students every year. We used the very same argument when designing courses in software engineering at Fraunhofer IESE. And yes, at lot of learners came.
There are lots of examples, where learning was brought in based on the promise that you could reach a large audience in an easy way. But I always felt that e-Learning had never really delivered on this promise. A course for a couple of hundred students. Good. A training solution for several thousand employees in a company. Nice. But only recently, we have seen examples of real scale. More than 100,000 people registered for a free on-line course on Artificial Intelligence offered by Stanford University. And 25,000 of them actually finished. Yes, that’s 25,000 people completing a hard, technical university course! Based on this success they have now started Udacity, a growing set of on-line lectures (all of them in Computer Science so far).
The phenomenon has been coined Massive Open Online Courses, MOOC, by George Siemens back in 2008 (see interview). Only now, it really gets massive. Similar offers are available from academic room and the by now well known MITx.
But we don’t even have to look that for to see the emerging trend. My esteemed colleague Eugene just celebrated the 1,000,000th view on his YouTube channel Learn with Dr Eugene O’Loughlin. The first million is always the hardest, but I am confident we will all soon be millionaires.

This year’s International Conference on Engaging Pedagogy is coming to NCI. One of the themes mentioned in the call for papersrefers to e-Learning: “The value of technology – Are we adopting new technology just because it is new or because it makes a difference?” That’s in fact one of NELL’s main concerns. Does it actually make a difference? Is there empirical evidence that suggests we should use this technology for a particular target group or a particular subject matter?
Submissions are due October 3, 2011. The conference itself will take place on December 16, 2011, here in NCI.

You are lecturing in Higher Education. You are an expert in your subject and in how to teach that subject. But you are not a usability experts-of course not. Nevertheless, you are required to create course pages in your institution’s Virtual Learning Environment for your classes.
If the above applies to you, then we have the solution for you. We developed a Style Guide for lecturers. It is intended as a support for lecturers when creating course pages in Virtual Learning Environments (VLEs) such as Moodle or Blackboard. The Style Guide offers a series of solutions of typical problems that can occur when making online materials and learning activities available.
The Style Guide is meant to be a living document. If you have any suggestions or comments, don’t hesitate to contact us or respond to this block post.
The Style Guide was developed in the context of the How do you Moodle? project and was supported by a grant from the National Academy for Integration of Research, Teaching and Learning (NAIRTL).
Just download the Style Guide and improve the learning experience of your students.
