When eating out, buffets can be both exciting and perilous. Buffets allow you to taste a little of this, and a little of that -- sample anything that looks interesting, and avoid the things that look unappetizing. On the other hand, it's easy to get carried away, and load up your cafeteria tray a little too full (hence why many colleges have moved to tray-less cafeterias, since juggling plates is apparently an effective antidote to this problem!).
So now I am staring at a number of partially eaten MOOCs on my plate, and although I may not have given the whole experience adequate time to digest, I'm going to offer some observations on the various MOOC courses and platforms I've crossed paths with.
1) Coursera. My first experience with
MOOCs was through Coursera, and as I mentioned in my previous post I completed two Coursera courses in 2012: one in
computer science, the other in business. Last year I also started
(but dropped) a third course on Cryptography. More recently, I got
enticed into Coursera's course on Data Science, and completed a
little over half of the course before other pressing events in my
(real-world) life caused me to fall behind. Coursera courses start
and end on a specific date, and have regular due dates for each
assignment/quiz, and once I fell behind, I lacked the time and
motivation to catch back up. After the course had ended, I was
surprised to discover that I had earned a 70% in the course (good
enough for a certificate), despite not completing the peer-reviewed
exercise or the second graded quiz.
This course was innovative in that it
provided an (optional) “real-world assignment” which matched up
students with non-profit organizations to analyze real datasets and
hopefully provide benefit to the organizations who provided the data.
At Centre College, we regularly do something similar in our Software
Engineering and Database courses, getting students to work on
projects for real clients who can actually benefit from software
solutions. While I didn't end up participating in this Coursera
assignment myself, the idea of pulling off this kind of
student-client match-up on a grand scale is intriguing. It's these
kind of creative assignments that help MOOCs move past the
working-in-isolation lecture-watching quiz-taking format. Of
course, fair assessment and grading of such assignments is going to
be a problem for MOOCs, but sometimes I think that grades are
overrated, and the experience of building/analyzing something real is
worth more to the student's education than a letter grade.
Furthermore, a well-done project could be added to a student's
portfolio and shown to potential employers.
I also enrolled in a Coursera course
called “Startup Engineering”, which I have dabbled with a bit –
mainly just to see what content/skills are covered in this course.
Finally, I'm pre-enrolled in a Coursera
course called “Video Games and Learning”, coming from the
University of Wisconsin in Madison. It's quite dubious that I'll
have time to really take this course, but to return to the central
metaphor for this blog post: I keep seeing more dishes that look
interesting, so I scoop them up and put them on my plate. (Even if
my plate is already full.)
2) Udacity. I have continued working
my way through the “Artificial Intelligence for Robotics” course
here, in fits and starts, and the little blue progress part shown on
the “My courses” page at Udacity suggests that I am about 2/3 of
the way through. My “self-pacing” in this course has been
decidedly unspectacular, with sporadic MOOC binging, followed by long
gaps. Perhaps because some of the material is familiar, I don't
find it riveting enough to stay “hooked”. Perhaps it's just my
natural proclivity toward perpetual procrastination, and getting
caught up in my own summer research projects. In any case, it raises
continued concerns that the self-pacing model will not work well for
some (many?) students.
Several months ago, I also signed up
for another self-paced Udacity course called “Differential
Equations in Action”, but have yet to complete the first lesson.
It's kind of like purchasing a (free) book that I think I'd like to
read some day, but for now it's just sitting on my bookshelf.
3) Open2Study. This is an Australian
MOOC platform, which is currently offering around 30 free courses
(but is also affiliated with Open Universities Australia (OUA), which
offers accredited online degree programs). I enrolled in a business
course called “Big Data for Better Performance”, but then forgot
about it. Unlike Coursera, which spews weekly emails into my inbox
to remind me about upcoming deadlines, course announcements, and
syllabus changes, Open2Study didn't nag me with reminders. In fact,
I signed up for it before it started, and then I forgot about it
until after the course was already finished, and I had (essentially)
“flunked” it. Though I daresay the term “flunked” doesn't
really apply to MOOCs... I didn't get a failing grade, because I got
no grade at all. The site simply informs me that “no certificate
was earned” for that course. Even though the course has officially
ended, it seems that I can still go back and watch the lectures and
take the quizzes – it just doesn't “count” for anything. Then
again, did it really “count” for anything to begin with?
Just today I signed up for another
course on Video Game Development at Open2Study. The smörgåsbord
strikes again.
I must say that some aspects of this system feel a bit childish... see screenshot below. A bit
surprising given Open2Study's affiliation with Open Universities
Australia. This message feels more “elementary-school” than
“collegiate” – but gamification runs rampant these days... and
it might really work.
4) Udemy. Udemy has a distinctly
different feel from the other MOOC providers. If Coursera, Udacity,
and EdX are all sit-down restaurants with chefs trained at
established culinary schools, then Udemy is a open-market bazaar
(without health inspectors or restaurant critics, but with plenty of
customer reviews to help you find the more reputable vendors and
tastier food trucks). That is, the courses at Udemy can be taught by
anyone – not just professors at elite institutions. In fact, if
you wanted to create your own course (about just about anything –
say “Viennese Waltz”, or “How to clean berry stains off of
anything”), you could make that course and offer it on Udemy.
(Think Youtube, but for education?) Another key difference is that
Udemy *does* charge for many of it's courses, although many are also
free. Or rather, the individuals who create the courses may charge
for the courses, and Udemy takes a cut of the profits.
I signed up for a free course on HTML5
at Udemy. It started off too elementary for me, since I am already
familiar with HTML, and just wanted to brush up on the latest
developments in web design, layout, and scripting. I may skip to the
later chapters, or I may ditch it entirely – we'll see. One thing
that I did think was particularly well-done in Udemy was the
integrated “note-taking” app that sat beside the video, allowing
you to jot down notes while watching the video, AND those notes are
hotlinked back to the time in the video that you took them,
effectively allowing you to bookmark key concepts and jump to them.
I haven't seen anything like it on Coursera or Udacity, but I think
it's a great step forward, and once again it moves beyond the mere
“recorded lecture plus quiz” format, to take advantage of the
interactive nature of the media. I'm including a screenshot below.
In general, I think this open exchange
marketplace for educational courses is a neat idea. But like many of
the MOOC options today, it lacks coherence of curriculum, and I have
trouble envisioning how it might replace a traditional college
experience. On the other hand, it seems like a cornucopia for
continuing education, especially for picking up new technical skills.
I expect Udemy (or sites like it) will be a commonly-used platform
for businesses looking to train workers in new technologies, or
workers looking to update their marketable skillsets.
5) EdX. I haven't taken any courses from EdX
yet, but I know someone who took one of MITx's introductory physics
courses, and who reported it to be quite academically rigorous, but
deficient because of lacking the hands-on “lab” component, which
is a key element for learning science.
6) Of course, there are a plethora of other MOOC providers (here's a fairly comprehensive list), but I won't discuss them since I don't have any personal experience with them to relate.
To recap: at this point, I've signed
up for 11 MOOCs in total, on four different platforms. Of these, I
have earned a certificate in 3, failed to complete 3, will probably
ditch 1 more, am still actively working on one, and 3 others are yet
to start. If I don't complete any more, my completion rate will be
around 27%, which probably still puts me well above average (given
the ~10% completion rates reported for many MOOCs).
Buffet-style schooling has some
important advantages over a traditional education (namely
flexibility), but also poses some challenges. It's up to you to make
sure you choose a healthy assortment of food, and you don't bite off
more than you can chew...
