Learning in MOOC Years

BY PROFESSOR DOUGLAS C. SCHMIDT

During the past decade I’ve taught software design and programming courses to roughly 600 undergraduate and graduate students at Vanderbilt. Our low faculty-to-student ratio is one of the reasons I like my work—it’s gratifying to watch students’ progress and envision the futures that lie ahead of them.

Not every bright student has the chance to come to Vanderbilt, of course. And worldwide, there’s an acute need for the kind of expertise we provide. So when I had the chance to teach one of Vanderbilt’s first Massive Open Online Courses (MOOCs) through the digital consortium Coursera this semester, I was intrigued. MOOCs pose many social, economic and technical challenges for the future of higher education, and here was my chance to experience some of them.

Since March, I’ve been teaching an eight-week MOOC, “Pattern-Oriented Software Architecture for Concurrent and Networked Software,” to more than 30,000 students from all over the U.S. and scores of other countries. In a traditional classroom it would take me 500 years to reach that number of students! Teaching a MOOC has been a learning experience for me, too—beginning with intense preparation that started months before the course launched.

Filming a video lecture used by 30,000 students as their primary exposure to course content requires much more preparation than a traditional class, a tighter script and great slides. It took two solid months of filming to produce 20 hours of video (split into more than 80 individual videos), and I prepared more than 1,200 slides for those videos.

Each week of my MOOC has featured more than two hours of lecture videos, broken into 10- to 20-minute chunks. I quickly had to master the art of presenting slides smoothly and at an even pace—and to maintain a high level of energy and enthusiasm while staring into the steely gaze of a video camera for hours on end.

The first session launched March 4. It didn’t take long for us to start receiving feedback, especially from students on the other side of the globe, where March 4 began hours earlier. That allowed us to quickly make corrections before students closer to Vanderbilt had even viewed the first materials.

Since that first session, the diversity of students—the bulk of whom are in their 30s and 40s—has proven to be both rewarding and challenging. For instance, I can rely on my Vanderbilt students having taken the course prerequisites, but Coursera enforces no prerequisites. For the MOOC we filmed an additional six hours of supplemental material to prepare less-experienced students.

Likewise, MOOC students with 20 or more years of experience as software professionals have much stronger preferences for particular programming languages, runtime platforms and software tools than typical undergraduates. I’ve found they ask more probing questions about the pros and cons of different technical approaches presented in the videos. We therefore spent much more time in the online discussion forums motivating and justifying the topics and techniques covered in the lectures, as compared with a traditional undergraduate course.

Learning involves much more than watching videos; it requires meaningful conversations between students and teachers. We used two primary social media tools—online discussion forums and webcasting—to make our MOOC feel much more like an interactive on-campus course. We used Google Hangout in conjunction with a YouTube channel to hold “virtual office hours.” Students asked questions via instant messaging, and I broadcast answers live. Google Hangout also automatically recorded all this material so students could review it at their convenience. As this social-media technology matures, it becomes feasible (though very time-consuming) for MOOC professors to engage in conversations with students that are similar in quality and quantity to those found in large lecture courses in many universities.

But how do you assess the performance of 30,000 students? In my traditional classes at Vanderbilt, I review and comment upon every line of software written by my students. That level of personalized scrutiny couldn’t happen in my MOOC. Moreover, the auto-grading tools available to assess students in a “fact-based” MOOC aren’t of comparable maturity for design-oriented courses in terms of assessing such attributes as reusability, understandability and evolvability. Peer assessment might provide one means of measuring student work, but we’d have to rely on students with a wide range of abilities evaluating each other’s solutions. These limitations only serve to underscore the invaluable role that expert judgment and evaluation play in fostering critical thinking for our on-campus courses at Vanderbilt.

So, aside from increasing knowledge for a greater range of learners, what benefit do MOOCs offer Vanderbilt? Coursera courses are free to the students and do not earn them Vanderbilt credits. However, the months spent preparing videos and lecture materials for my MOOC have significantly improved my on-campus courses. My material is organized better than ever, due in no small part to contributions from MOOC students. The high-quality material we produced for my MOOC will enable my on-campus students to personalize their learning. They can watch videos at their own pace, read transcripts, and learn from the discussion forum. Moreover, I’m restructuring my on-campus course for this fall to apply a “flipped classroom” model, using the videos we created for the MOOC to shift some of the lecture content outside of class time, leaving more time for classroom interaction.

The material we’re creating for our MOOCs also can be applied to better connect with Vanderbilt alumni and involve them more in the intellectual life of the university. Likewise, our high-quality education is now visible to thousands of bright students around the world, which encourages them to apply to Vanderbilt and partake in the exciting learning culture happening here.

In this rapidly changing and globally competitive environment, we must continue to clarify and refine the value of an immersive college education that builds upon our interdisciplinary strengths in teaching, research, entrepreneurship and innovation. I’ve had a great experience creating and teaching a MOOC at Vanderbilt during the past few months, which seem like an eternity in “MOOC years.” Vanderbilt’s experience has positioned us for a leadership role in the most effective use of MOOCs and other emerging digital-learning technologies in the coming years.

    It’s refreshing to hear the opinion of someone who is open-minded about MOOCs while able to take a serious look at their limitations. Too much of the conversation is automatically dismissive, and some of the rest doesn’t hold MOOCs to high standards. How they benefit an institution like Vanderbilt is uncertain, as your experience makes clear, and what we’re hearing from our contributors is much like the story you tell — that it significantly energizes and transforms on-campus teaching.

    As you say, a month is an eternity in MOOC time and the limitations you describe are looking different every day. Just today we have a close look at new research in peer assessment. It’s hard to see how that will ever solve the problem of grading a massive number of students, but a month ago, it was hard to see what’s happening now.

    Congratulations on what sounds like a successful semester.

    Thank you professor for your vision which will give all in a “Win Win” situation around the world.

    You are very correct in stating that to learn in this kind of course each student need to spend more time than just watching videos – you want to take this MOOC to another level with more interactions and making the course more challenging.

    I have gone through some of your lectures this time which were interesting.

    Looking forward to your next class.
