What’s Wrong With Online Education - and How to Fix It

There are many things right with online education—like the plethora of free and easily accessible content developed by Udacity, Coursera and others. In particular, online education excels at teaching while using simulations and improving instruction by making sense of data submitted by the learner.

But many others have written about the power of online education. This article is not about that.

For all online education’s potential, there are still some key difficulties holding it back. And the sooner we tackle these challenges, the sooner we’ll be able to unleash its potential.

Here are the three most difficult challenges facing online education today.


Learning online is good at multiple-choice questions. While this technique works well for the test makers, it is generally not effective at pushing learners to think of new ideas.

The tension, of course, is that the greatest strength of online education—that one or few educators can reach tens of thousands of students in a single class—is also its greatest weakness. There is simply no way for the teacher to interact with every single student.Open-ended questions are encountered in the workplace on a regular basis and any effective learning space will simulate conditions for students to practice such inquiries. Online education, however, has historically been terrible at providing feedback on questions like “How will you break this problem down?” and prompts like “Do you agree with this argument?”

Technologies like natural language processing have not matured to a point where feedback on open-ended responses is satisfactory. So, as it turns out: an attentive teacher, providing timely comments in the classroom, is still our best technology in this space.

But there is hope.

Recently, I discovered some techniques that can provide effective feedback to open-ended explorations at scale. Of particular note is Prof. Scott Klemmer’s work with peer assessment. His research at Stanford University suggests that students armed with a robust rubric can provide feedback and grades that “correlate highly with staff-assigned grades.”


Students are a key asset of massive online open courses. Currently, however, learners in an online class work mostly on digital islands quarantined from all other landmasses.

I think an ideal online learning space would resemble Samba schools in Brazil, where learners of different ages and expertise work together. The closest I have come to experiencing this was in grad school when I collaborated with teaching assistants and peers in the library.By connecting students, who are either geographically close or online concurrently, leads to explorations like “Does someone else have this same problem?” and “Can I see how an expert would solve this challenge?”

As an industry, we have started to make a few attempts at bringing learners together. Discussion forums on Udacity are a reasonable start; Coursera is experimenting with learning hubs; and NovoEd requires learners to take courses as a group. The challenge for our industry, however, remains in figuring out how to connect learners in an asynchronous setting.

Expert’s Blind Spot

Think of a skill you have been practicing for years; this could include addition or programming or building rockets. Now, while this act of deliberate practice helps us become an expert in those subjects, it also separates us from recalling what it felt like to be a novice.

Internalizing new ideas until they are almost intuitive, it turns out, is a key component of learning. But unpacking these ideas for novice learners, laying out every concealed gear and spring, is a key component of teaching. It is in this unpacking of ideas where many experts fail.

In other words, the teachers tended to believe certain problems were easier than they actually were.The expert’s blind spot is a hypothesis that suggests that instructors are not always good at predicting the difficulty level of new ideas for students. This hypothesis was first established in a study by Koedinger and Nathan. The study showed a deviation between how math teachers rated the difficulty of problems and actual student performance on the same problems.

This is a challenge for teachers everywhere including those teaching online. There are two potential resolutions.

The first would use data collected in an online course to identify and resolve such events. Candace Thille, a professor at Stanford University, talks about using student quiz responses to help instructors identify points in the course where their “students are struggling.”

Prototyping online courses with representative learners is another way to help identify blind spots. Stanford University’s d.School offers some effective strategies on how to implement low-fidelity prototypes that can help capture relevant feedback to improve courses.

No Silver Bullet

These are my top three challenges for online education, but they are by no means the only ones. And while there are no silver bullet solutions, I believe that if we move beyond the hype and discuss these challenges frankly, we can realize online education’s full potential.

I also want to hear from you.
