Online teaching does not fail because the internet is slow or the platform is imperfect. It fails when students feel like spectators of content rather than participants in learning and that is a design problem, not a technology problem.
Introduction
Picture a typical online class in a Nigerian university. Fifty students join a video call. The lecturer shares their screen and begins to speak. Within ten minutes, some students have muted themselves and opened another tab. By twenty minutes, a third of the room has become a gallery of black squares; cameras off, names visible, presence uncertain. The lecturer continues speaking into the silence, unsure who is listening and increasingly aware that something essential is missing.
What is missing is not better internet. It is not a fancier platform. It is participation, the sense that students are not watching the class but are part of it, that their responses shape what happens next, that being present means something beyond having a name in the attendee list.
Since the pandemic accelerated online teaching across Nigerian institutions, a divide has emerged between lecturers who simply transferred their face-to-face delivery onto a screen and those who redesigned their sessions for the online environment. The first group found that what works in a lecture hall often fails on a video call. The second group discovered that online teaching, done well, can be more flexible, more documented, and in some ways more participatory than the face-to-face equivalent.
The five strategies below belong to the second group. They are practical, low-bandwidth, and immediately applicable, regardless of which platform your institution uses.
The camera on a student’s screen is not a window into their attention. Engagement in an online class must be built, it cannot be assumed from presence alone. – Adapted from online learning research, post-2020
| Student attention online ~8 min before disengagement without an active task or mode shift | Engagement with breakout rooms Rises significantly, small groups restore the social dynamic that full sessions lose | Students with unreliable data Many in Nigerian HE, strategies must work with low or intermittent bandwidth |
Why online classes disengage vs what re-engages
| What switches students off | What switches students on |
| One person speaking for 60–90 minutes without pause | Mode shifts every 8–10 minutes — instruction, task, discussion |
| No clear signal that students are expected to respond | Clear, specific invitations to respond, be it chat, poll, voice |
| Technical issues handled with long, awkward silences | Calm, brief acknowledgement of tech issues, then move on |
| No structure; students don’t know what comes next | A visible session agenda shared at the start |
| Camera-off culture normalised with no alternative | Low-data alternatives such as chat, typed responses as participation options |
Five strategies for more engaging online sessions
1. Share a session agenda at the very start
One of the most disorienting aspects of a poorly designed online session is not knowing how long it will last, what will happen, or when participation is expected. A simple agenda, shared as a screen share or pasted into the chat at the beginning of the session transforms this. “Today we will cover three things: a 10-minute review of last week, a 20-minute input on today’s topic, and a 15-minute group task. We will finish by 11:00.” This single act reduces student anxiety, keeps the session on track, and signals that the lecturer has prepared with intention. Students who know what is coming are more likely to stay present, because they can see the shape of the session they are committing to. It also makes it significantly easier to manage time, because you have named the structure publicly and made yourself accountable to it.
Try it: Type today’s three agenda items into the chat at the start of your next online session before saying anything else.
2. Shift modes every 8–10 minutes
The attention span for passive video viewing is shorter than for face-to-face instruction and in an online environment, every competing tab, notification, and household distraction is one click away. The most effective online sessions are built around mode shifts: the lecturer speaks for 8–10 minutes, then the mode changes, students type a response in the chat, work alone on a short task, discuss in pairs via voice or text, or answer a poll question. The content of the mode shift matters less than the shift itself: the act of changing what students are doing resets their attention and re-establishes their active presence. For Nigerian lecturers managing low-bandwidth environments, the shift does not need to involve video or complex tools, a 2-minute typed response in the chat followed by the lecturer reading two or three responses aloud is enough to transform a passive session into an active one.
Try it: In your next session, set a silent timer for 10 minutes. When it goes off, pause and ask students to type one response in the chat before you continue.
3. Use the chat actively: it is your most reliable participation channel
In most online classes, the chat goes largely unused, a space where a few students ask logistical questions and the rest watch. Used deliberately, the chat becomes the most democratic participation channel in the session: every student can respond simultaneously, responses do not require unmuting or camera-on, and the lecturer can read several responses aloud and build on them in real time. Specific, low-stakes prompts work best: “Type one word in the chat that describes the concept we just covered.” “Reply in the chat with the first question this topic raises for you.” “Rate your understanding of that point in the chat, using 1 is confused, 5 is clear.” These prompts cost nothing, require minimal data, and transform a passive gallery into an active group. They also give the lecturer real-time diagnostic information about where students are, which is exactly what a raised hand in a silent Zoom session almost never provides.
Try it: Ask students to rate their understanding in the chat from 1 to 5, after every major concept. Read the range of numbers aloud and respond to what you see.
4. Use breakout rooms for discussion, even briefly
The full-group video call format eliminates one of the most natural features of face-to-face learning: the ability to turn to the person next to you and think out loud. Breakout rooms, small groups of three to five students split off from the main session for a short, structured task, restore exactly this dynamic. Even a five-minute breakout with one clear question to discuss produces a measurably different quality of engagement than asking the same question to the full group. Students who would never unmute in a room of fifty will speak freely in a group of four. For Nigerian institutions where bandwidth is variable, breakout rooms also reduce the number of simultaneous video streams, which can actually improve connection quality. The task must be specific: “In your breakout room, discuss which of the two case studies better illustrates the concept, you have 5 minutes, then share one sentence back with the full group.”
Try it: Use one 5-minute breakout room session in your next online class. Give a single, specific discussion question and ask each group to report back in one sentence.
5. Provide asynchronous options for students with connectivity challenges
In the Nigerian higher education context, not every student can reliably access a live video session, data costs, unstable connections, and shared devices are realities that no amount of engagement strategy can override for every student. An engaging online class therefore includes an asynchronous pathway: a short recorded video of the session’s key content (or a voice note summary via WhatsApp), a PDF of the session notes, and a written task students can complete after the live session and submit via a shared channel. This is not a lower-tier option, it is an equity measure that ensures your engagement work reaches students who cannot participate live without penalizing them for circumstances outside their control. It also creates a permanent resource library that benefits all students, including those who attended live but want to review the content before assignments or examinations.
Try it: After your next live session, record a 3-minute voice note summary of the key points and share it on your class WhatsApp group.
A model 60-minute online session structure
| Time | What happens |
| 0:00 – 0:05 | Open and orient Paste agenda into chat. Greet students by name as they join. Brief 1-minute check-in question in the chat to settle the room. |
| 0:05 – 0:10 | Review last session Three key points from last week. Ask students to type one thing they remember in the chat. Read two responses aloud and build on them. |
| 0:10 – 0:20 | Input: segment 1 First 10-minute block of new content. Speak clearly, share screen if relevant. End with one chat prompt: “What question does this raise for you?” |
| 0:20 – 0:30 | Breakout task Groups of 3–4 students. One specific question. 5 minutes in rooms. 3 minutes reporting back, one sentence per group, typed into chat. |
| 0:30 – 0:40 | Input: segment 2 Second 10-minute block of content. Respond to one or two chat questions from the first segment. End with a 1-minute comprehension poll or chat rating. |
| 0:40 – 0:55 | Independent task Students work alone on a short written task for 10 minutes. Lecturer circulates in breakout rooms or monitors chat. Task connects directly to today’s content. |
| 0:55 – 1:00 | Close and preview Summarise three key points. Name the next session’s topic. Share the asynchronous resource either by voice note, PDF, or WhatsApp summary immediately after the call ends. |
Transforming passive online moments into active ones
| Passive approach | Active alternative |
| Does everyone understand? Good. Let’s move on. | Type a 1 to 5 in the chat, 1 means confused, 5 means clear. I’ll address the 1s and 2s before we continue. |
| Asking a question to the whole room and waiting in silence for someone to unmute. | “Type your answer in the chat first, you have 60 seconds. Then I’ll ask one person to share verbally.” |
| Showing a slide with dense text and reading from it for 15 minutes. | Show the slide for 5 minutes. Then hide it and ask students to type one thing they remember before showing the next point. |
| Ending the session with “See you next week” and no summary. | Before we go, type one thing you learned today and one thing you are still unsure about. I’ll address the second category at the start of next week.” |

From a virtual lecture hall in Lagos
A lecturer in the Department of Sociology at a Lagos university had been running weekly online sessions since 2020. By 2022, she had noticed a pattern: attendance was adequate, but participation was almost zero. Students joined, turned their cameras off, and waited for the session to end. She felt she was teaching to an empty room.
She made three changes to a single session as an experiment. She pasted the agenda into the chat at the start. She stopped every ten minutes and asked a specific typed question, not “any questions?” but “type one word in the chat that describes what we just covered.” And she split the class into breakout groups of four for a five-minute discussion task in the middle of the session.
In that single session, 34 of her 47 students typed at least one response in the chat, compared to an average of three in previous sessions. Two students who had never spoken in any online session shared their breakout group’s point back with the full class. She had not changed the content, the platform, or the time. She had changed the structure and the structure had changed the room.
Your action step this week
In your next online session, implement just one of the five strategies above, the one that feels most achievable given your platform and class size. If you choose nothing else, choose the chat prompt: after your next input segment, pause and ask students to type one word, one number, or one sentence in the chat. Read two or three responses aloud. Build on what they say. That single exchange of 90 seconds, zero additional preparation, is often the difference between a session students feel part of and one they merely attend.
