Why Your Online Course Feels Empty: The Case for Designing for Transactional Distance

Imagine you are a student, sitting alone at your kitchen table at 11 p.m., staring at a lecture video that was recorded three years ago. You have a question, but there is no one to ask. The discussion board is a ghost town. You feel like you're shouting into a void. This is not a failure of your self-discipline; it's a failure of course design.

We keep blaming learners for dropping out of online courses. We say they lack motivation, or they can't manage their time. But the data tells a different story. A 2024 comparison found no statistically significant difference in GPA or retention between online and face-to-face learners, concluding the two modalities are equally effective (US News). If online learning is just as effective when it works, then the problem isn't the medium—it's the design.

The question I want to answer today is this: Why do so many online courses feel empty, and what can course designers do about it? The answer, I believe, lies in a concept that most course creators ignore: transactional distance.

The Invisible Gap

Transactional distance is the psychological and communication gap between learner and instructor that can develop when interaction is insufficient (Touro University). It's not about physical distance—you can be in the same room as someone and still feel miles apart. In online learning, this gap grows when students feel disconnected from the instructor, from their peers, and even from the material.

Think about a typical online course. You watch a video, read a PDF, take a quiz. The instructor is a disembodied voice, or worse, just a name on a syllabus. The only time you hear from them is when you get an automated email reminder. This is a recipe for transactional distance.

And the consequences are real. A survey of online students found that 59.4% cited limited interaction with others as a drawback, and 44.1% reported social isolation (US News). These aren't trivial complaints; they are the symptoms of a design that prioritizes content delivery over human connection.

Why We Keep Building Empty Courses

Part of the problem is that online education has been shaped by the MOOC model. Coursera and edX, launched in 2012 by well-meaning academics, promised universal access to world-class learning (Coursera, edX). But their courses were designed for scale, not for connection. They had to be, because they enrolled millions of learners. edX reports 100 million learners worldwide (edX); Udemy has 84 million learners and 290,000 courses (Udemy). You can't have a meaningful conversation with 100 million people.

But most online courses aren't MOOCs. They are small, credit-bearing courses at colleges and universities, or professional development for working adults. Yet we still design them as if they were mass-produced content factories. We record lectures, upload them to an LMS like Canvas or Blackboard, and call it a day.

This approach ignores the fundamental difference between synchronous and asynchronous learning. Synchronous learning happens in real time—live classes or webinars—while asynchronous learning lets learners access materials on their own schedule (Touro University). Asynchronous is flexible, and flexibility is the top reason students choose online: 77% cite studying from home and 69.4% cite self-paced learning (US News). But flexibility without interaction creates isolation.

Designing for Connection

So what does a connected online course look like? It starts with acknowledging that interaction is not a luxury; it's a necessity. The research shows that when interaction is insufficient, transactional distance grows. So we need to design interaction into every aspect of the course.

First, the instructor must be present. This doesn't mean 24/7 availability, but it does mean regular, meaningful communication. A weekly video announcement, personalized feedback on assignments, or a live Q&A session can dramatically reduce the feeling of distance. In my experience, even a simple, human message like “I read your post and here's what I think” can make a student feel seen.

Second, peer interaction matters. Discussion boards are a staple, but they often feel like a chore. Instead, consider small group projects or peer review, where students actually have to talk to each other. The data shows that 95% of learners who completed an edX Professional Certificate program would recommend it (edX). Why? Because those programs often include cohort-based learning and peer support, not just videos.

Third, the course structure itself should reduce the gap. This means clear navigation, timely feedback, and a predictable rhythm. If a student knows that the instructor responds within 24 hours, they feel less alone. If they know that every Friday there's a live chat, they have something to look forward to.

The Cost of Ignoring This

Ignoring transactional distance has a direct impact on retention. Retention at primarily online institutions averages about 49%, according to the National Student Clearinghouse (US News). That means more than half of students at fully online schools don't come back. And while some of that is due to external factors, a significant portion is due to the feeling of being adrift.

We also know that online students are often juggling a lot. In a 2023 BestColleges survey of 1,800 online students, 68% were employed full- or part-time, and 95% had children under 18 in their household (BestColleges). These are busy people who need flexibility, but they also need support. If they feel isolated, they will drop out.

One concrete example: a student named Maria is a single mother working full-time. She's taking an online nursing course. She can only study at 10 p.m. after her kids are asleep. If her course is entirely asynchronous with no instructor presence, she will likely struggle. But if the course includes a weekly synchronous review session (even optional), and if the instructor sends personalized reminders and feedback, she is more likely to persist. This isn't fluff; it's the difference between a student who completes and one who disappears.

A Practical Fix

So here is my recommendation: when you design an online course, start with the interaction, not the content. Ask yourself, “How will my students interact with me, with each other, and with the material?” Then build the course around those interactions.

This might mean sacrificing some content. You don't need 20 videos when 10 will do, if you add a live discussion. You don't need a 100-question quiz if you assign a collaborative project. The goal is to reduce transactional distance, not to cover every possible topic.

And for administrators: spend your money on people, not just technology. The fact that 47% of administrators plan to increase spending on online learning programs (BestColleges) is good, but if that money goes to a fancier LMS and not to training instructors or hiring instructional designers, you're missing the point.

Quick tip: If you're designing a course, try this: schedule one live, synchronous session per week, even if it's just a 30-minute check-in. You'll see the difference in student engagement.

The Takeaway

The empty feeling in online courses is not inevitable. It is a design flaw. By understanding and addressing transactional distance, we can create courses that are not only effective but also humane. We can build online learning that respects students' need for flexibility while still offering the connection that makes learning meaningful. The data is clear: online can be just as effective as face-to-face, but only if we design it that way. Let's stop blaming the students and start fixing the design.
