Should Online Courses Have Less Students, Why? – Faculty Focus

Online courses have a funny reputation. On one hand, they are praised as modern, flexible, and gloriously pants-optional. On the other, they are sometimes treated like magical inflatable classrooms: just keep adding students, and surely nothing bad will happen. Spoiler alert: something usually does.

The question of whether online courses should have fewer students is not really about nostalgia for smaller classrooms or professors wanting fewer discussion posts to read at midnight. It is about teaching quality. When class rosters swell in an online course, the first things to wobble are usually the things students remember most: timely feedback, meaningful interaction, a sense of belonging, and the feeling that a real human being is teaching the class instead of an exhausted grading machine.

That does not mean every online course should be tiny. Some can scale well. But many cannot, at least not without redesign, staffing support, or different expectations. So the wiser question is not, “Should all online courses be smaller?” It is, “Which online courses need lower enrollment caps, and why?” Once you ask it that way, the answer gets a lot more useful.

Why class size matters more online than many people assume

People sometimes imagine online teaching is easier to scale because there are no physical walls. No one has to find a bigger room. No one is dragging in extra chairs. The virtual classroom looks infinite, so administrators may be tempted to think enrollment can be infinite too. But online teaching has a different bottleneck: instructor attention.

In a face-to-face lecture hall, a professor can address 100 students at once and still create a shared moment. In an online course, especially an asynchronous one, teaching often happens through hundreds of smaller moves. There are announcements to write, confused emails to answer, discussions to facilitate, assignments to grade, and students to nudge before they quietly disappear into the digital wilderness. Each added student increases that labor, and not in a cute little linear way. Once the class gets too large, the course often shifts from teaching to traffic control.

This is why online class size is not just an administrative number. It is a design decision. The enrollment cap shapes what kind of course can realistically exist. A writing-intensive seminar with weekly feedback cannot be treated like a content-delivery survey course. A project-based class where students need coaching cannot be run like an auto-graded quiz factory. If the cap ignores the pedagogy, the pedagogy eventually loses.

The biggest reason smaller online classes often work better: interaction

The strongest argument for lower enrollment in many online courses is simple: interaction gets better. And not the fake kind where everybody posts “I agree” and vanishes into the fog. Real interaction. The kind where students get specific feedback, where instructors remember who is struggling, and where discussions feel like conversations instead of a crowded airport terminal.

Online learning lives or dies on intentional engagement. Students cannot rely on hallway chats, quick after-class questions, or reading the room. If they are going to feel connected to the course, the instructor has to build that connection on purpose. That takes time and presence. In a smaller section, an instructor can respond thoughtfully, spot patterns in misunderstanding, and make students feel seen. In a bloated section, even the most dedicated faculty member starts triaging.

And triage changes the student experience fast. Feedback becomes shorter. Discussion replies get generic. Office hours become harder to use. Students who are quiet, confused, or barely hanging on become easier to miss. A large online course may still “run,” but running is not the same thing as teaching well.

Feedback is where large online classes usually start to break

If online education had a secret villain, it would be the feedback pile. Students need feedback for improvement, reassurance, correction, and momentum. In many online courses, feedback is not a bonus feature. It is the teaching.

Think about a course with 25 students submitting a weekly short paper. That is already a substantial amount of reading and response. Increase the roster to 45 or 60, and suddenly the instructor is buried. Even with efficient rubrics and strong course design, quality starts slipping. Comments get briefer. Turnaround slows down. Students receive less coaching and more shorthand. The course may still check the box for assessment, but it stops feeling intellectually alive.

This is especially important in courses built around writing, problem-solving, case analysis, presentations, design work, or applied projects. In those settings, students are not just absorbing information. They are trying to do something complex and improve over time. That kind of learning depends on guidance. If the instructor does not have enough bandwidth to offer it, the course becomes less transformational and more transactional.

Community is not fluff. It is infrastructure.

One of the sneakiest problems in large online classes is isolation. A student can log in, submit work, and still feel like they are taking the class alone on a remote island with weak Wi-Fi and existential dread. Smaller sections make it easier to create a genuine classroom community, which matters because community is tied to persistence, participation, and confidence.

When students believe their instructor notices them and their classmates know their names, they are more likely to ask questions, contribute ideas, and keep going when the course gets tough. In a smaller online class, the instructor can establish routines that support this: personalized announcements, targeted check-ins, meaningful discussion prompts, small-group activities, and visible presence throughout the week.

In a larger section, those same strategies become harder to maintain consistently. Discussion boards get cluttered. Students stop reading each other’s posts because there are too many. The instructor has less room to personalize communication. What remains is structure without warmth. The course may be technically organized, but emotionally flat. And in online learning, emotionally flat can quickly become academically fragile.

Not every online course needs the same enrollment cap

Here is where the conversation gets more interesting. The best evidence does not support one magic number for all online courses. That would be too easy, and higher education rarely chooses the easy route unless it involves a committee.

Some online courses can function well with higher enrollment. Introductory or foundational courses that focus on factual knowledge, use highly structured modules, and rely on objective assessments may be able to handle larger rosters. If the course is carefully designed, supported by teaching assistants or graders, and not dependent on extensive individualized feedback, scale is more realistic.

But other courses deserve smaller caps. Upper-division classes, graduate seminars, writing-intensive courses, studio-style classes, capstones, project-based learning, and many STEM courses often require more back-and-forth between instructor and student. The same is true for courses serving students who may need more academic support, more scaffolding, or more encouragement to stay engaged in an online environment.

That is why one-size-fits-all policy usually fails. A blanket cap of 40 may be perfectly manageable in one course and quietly disastrous in another. Smart institutions stop asking for a universal cap and start asking what the course is trying to accomplish, what kinds of interaction it requires, and what support the instructor has.

When fewer students are most justified

Writing-heavy and feedback-heavy courses

If students are producing frequent written work, reflections, case analyses, research critiques, or portfolios, a smaller roster is usually the difference between actual mentoring and survival-mode grading.

Upper-division and graduate courses

Advanced courses often require nuance, coaching, and higher-order thinking. Students are not just memorizing; they are analyzing, synthesizing, designing, and defending. Those are not activities that scale gracefully without losing quality.

STEM and problem-solving courses

Some online STEM courses seem especially sensitive to class size because students often need clarification, worked examples, intervention when misconceptions pile up, and more frequent course contact.

Courses with intensive discussion expectations

If discussion is central to the learning experience, oversized enrollment can turn the conversation into static. Students end up skimming instead of engaging, and instructors end up moderating volume rather than facilitating thought.

Courses serving newer or more vulnerable online learners

Students who are balancing work, caregiving, military service, or a return to school after a long break may benefit from more visible instructor presence and quicker feedback. Smaller sections make that more feasible.

When larger online classes can still work

To be fair, larger online classes are not automatically bad. They just need honest design. A high-enrollment online course can succeed when expectations are clear, assessments are structured, materials are well organized, and the course team is set up to support students at scale. That might include graders, facilitators, tutoring support, embedded librarians, or carefully managed discussion groups.

It also helps when the learning goals match the structure. If the course is primarily introductory, if content can be chunked clearly, if quizzes provide fast feedback, and if students are not expected to receive detailed weekly coaching from one instructor, then a larger cap may be workable. The mistake is assuming a large section can run the same way as a small one. It cannot. Either the design changes, or the quality does.

The policy angle institutions should not ignore

There is also a practical compliance issue hiding in this debate. In U.S. higher education, online distance education is expected to include regular and substantive interaction initiated by the instructor. That requirement is not just educationally sensible; it has policy implications. If a course is so overloaded that meaningful instructor-initiated interaction becomes sporadic, shallow, or performative, institutions are playing a risky game.

Now, large enrollment does not automatically violate anything. But it does raise a simple operational question: can the instructor realistically sustain predictable, academically meaningful interaction with this many students in this specific course design? If the answer is “only by typing with both hands, one elbow, and a heroic amount of caffeine,” the cap may be too high.

What colleges should do instead of arguing in circles

The healthiest approach is not ideological. It is practical. Colleges should set online enrollment caps based on course type, learning goals, assessment load, level of study, and available instructional support. In other words, they should act like course design matters, because it does.

A sensible framework might look like this: foundational survey courses can carry higher caps if they are intentionally built for scale; discussion-intensive and feedback-heavy courses should have lower caps; upper-division and graduate courses should be reviewed separately; and any course with unusually high labor demands should be capped in relation to actual instructional workload, not wishful thinking.

Institutions should also stop pretending that online teaching somehow requires less labor because students are not physically in the room. Faculty time in online teaching is real time. Discussion facilitation, grading, outreach, troubleshooting, and presence-building do not happen by magic. If a college wants quality online education, it has to account for labor honestly.

So, should online courses have fewer students?

Often, yes. Not always. But often enough that the question deserves serious attention.

Online courses should generally have fewer students when the course depends on strong instructor presence, rich feedback, active discussion, higher-order learning, or close monitoring of student progress. They do not necessarily need lower caps when the course is highly structured, supported appropriately, and designed for scale from day one. The trouble starts when institutions confuse “possible to enroll” with “wise to enroll.”

That distinction matters because students can feel the difference. They know when a course is thoughtfully designed for learning and when it is simply overstuffed. They know when feedback is helpful and when it sounds like it was written during a fire drill. They know when the instructor is present and when the course feels like an abandoned shopping mall with discussion boards.

In the end, smaller online classes are not about coddling faculty or resisting innovation. They are about matching course size to educational purpose. If colleges want online learning to be flexible, rigorous, humane, and effective, they should stop asking how many students can technically fit into the LMS and start asking how many students a course can truly teach well.

Experience from the online classroom: what this looks like in real life

Ask faculty who have taught both small and large online courses, and you will often hear the same pattern. The small class feels like teaching. The large class feels like managing a system. That does not mean the large class is worthless. It means the instructor’s role changes in visible ways.

In a smaller online section, an instructor can notice when a student’s tone changes. Maybe discussion posts get shorter. Maybe assignment quality dips. Maybe a usually active student goes silent for a week. In a class of 18 or 22, those signals are easier to catch. The instructor can send a quick note, ask a question, or offer help before the student falls too far behind. That tiny moment can be the difference between retention and withdrawal.

In a larger section, those moments become harder to spot. The LMS is full of activity, but the instructor’s attention is fragmented. One student misses a deadline, another asks for clarification, ten more post discussion responses, and twenty essays land in the grading queue all at once. By the time the instructor identifies who needs support most, the week is already over and the next deadline is marching in like it pays rent.

Students notice this too. In smaller online classes, they often describe the course as more personal, even when they never meet anyone in person. They say the professor felt present. They say classmates actually responded to each other. They say feedback helped them improve instead of merely informing them that they had, in fact, submitted words. That feeling of academic closeness matters, especially online, where the distance is already built into the format.

There is also a morale issue for faculty. Instructors are usually willing to work hard. What wears them down is work that feels impossible to do well. A roster that is too large for the course design creates a constant sense of compromise. The instructor knows the feedback could be better, the outreach could be earlier, and the discussion could be deeper, but time says otherwise. Over time, that mismatch can lead to frustration, burnout, and a lower-quality learning experience for everyone involved.

The most successful online programs tend to understand this. They do not rely on optimism alone. They align enrollment, course design, and staffing. They reduce unnecessary friction, provide support, and build courses around how teaching actually happens online. That is the part people sometimes miss. The class-size conversation is not really about smaller numbers just for the sake of smaller numbers. It is about preserving the conditions that allow learning to feel responsive, challenging, and human.

Conclusion

Online courses do not automatically need fewer students, but many of them absolutely need smarter caps. If a course requires discussion, detailed feedback, coaching, and sustained instructor presence, a smaller roster is not a luxury. It is part of the educational model. If the course is foundational, tightly structured, and built with support for scale, larger enrollment may be reasonable. The right answer depends on what students are supposed to learn and what it takes to teach that well online.

The best institutions will stop treating online class size as a budgeting afterthought and start treating it as a quality decision. That shift matters because online learning is no longer a side project. It is a central part of higher education. And if colleges want it to be effective, they need to stop packing digital classrooms like carry-on luggage and pretending nothing will wrinkle.
