The Ghost in the Machine

Derrida, Différance, and the Online Classroom

The emails start before the semester begins. Not introductions; only questions about logistics: “Where are the readings posted?” “Is the syllabus finalized?” “Will there be synchronous sessions?” I answer each one. The students are eager. They want the course. And yet the exchange remains transactional at the help desk level, even when the interest behind it is genuine.

I don’t blame them. Most of my graduate students are working professionals logging on after long shifts, after their children are fed and put to bed, after a long day. They are not looking for another relationship to manage. They want to learn what they came to learn. I understand that. I respect it. And I still feel the distance.

What I notice, as the weeks pass, is that students who reach out are almost always writing about logistics rather than ideas. A clarification about the assignment. A question about the reading. A technical issue with Canvas: a dead link, a discussion board that hasn’t opened yet, a module that doesn’t match the syllabus. In the classroom, by contrast, there are moments before and after class, a student lingering in the hallway, a conversation that starts with a question about the syllabus and ends somewhere neither of us expected. Online, the conversation ends where it begins.

The exchanges are polite, sometimes warm, but never surprising.

Nobody writes to say they have been thinking about Dewey.

This is what Jacques Derrida called différance: the deferral of meaning between the sign and what it points toward. It is also what he called la trace—the mark left by what was never fully present. In the online classroom, I never encounter the student; I encounter their trace. The discussion post comes already composed, the moment of confusion already worked through, the thinking already resolved into sentences. I am reading the representation of a mind I cannot otherwise reach. The person who wrote it is elsewhere, already back inside the rest of their life.

This is an ontological condition, not a technological one.

Higher education has long operated on what Derrida termed the “metaphysics of presence,” a deep assumption built into Western philosophy that truth, meaning, and reality are most fully available in direct experience. Speech over writing. The ‘living voice’ over the recorded one. The face-to-face over the mediated. Being there over being represented. In education, this settles into the conviction that “real” teaching requires bodies in a shared space, a voice carrying across a room, a mutual recognition between professor and student. It is an assumption so deeply embedded that asynchronous online instruction is treated as a substitute, almost reflexively.

For Derrida, what begins as a supplement ends as a foundation. Writing was once dismissed as a mere supplement to speech; instead, it shapes thought, preserves argument, and allows thought to survive its speaker. The online classroom, then, is a different kind of encounter. It exists on its own terms.

But the same distance exists in the classroom. It always has. A lecture was always a performance of authority as much as a transmission of knowledge. A classroom was always structured by who spoke, who stayed silent, and who participated. Being in the same room does not close that distance. Proximity does not guarantee understanding; it merely guarantees proximity. But in the classroom, the distance is easier to forget. The body, the voice, and the eye contact create the impression of access to another person. Online, that impression is unavailable. It is there.

From my perspective, the student is a trace, never quite absent, but never fully present. To them, I am equally spectral: a voice without a body, authority stripped of its usual anchors, a name on a syllabus tethered to words on a screen.

Across several semesters of course evaluations, students keep naming the same moment as the one when the course came alive: the weekly synthesis. In a classroom, I can look at a student, name their idea, and turn it toward the group — a gesture that disappears into the air the moment it is made. Online, that recognition must become text, or it does not exist. I map the movement of a thought as it migrates from one student’s post to another’s, naming the contributors as if calling roll in a room where no one is sitting. One student noted that this made the course more alive than other online courses she had taken. Another said it was the first time feedback had helped her improve. A third noted that even though she always read everyone’s posts, the synthesis helped her see patterns she had missed. The students take this not as a replacement for being present, but as a sign that someone is paying attention from a distance. The synthesis is itself a trace — written, sent, permanent. The students can return to it after the week has closed. The gesture I make in a classroom disappears the moment it is made; the synthesis does not. In forcing me to leave traces, the online classroom may have made the supplement foundational after all.

I have also learned about my own teaching. The synthesis forces a discipline the classroom never required of me: I have to read every post carefully enough to map the thinking, name the contributors, and track where one student’s idea became another’s. In a classroom, I could coast on the impression of attention — a nod, a question, the performance of presence. Online, coasting is visible.

But the longing keeps appearing in the evaluations. One student wrote that she wished the course had included synchronous sessions to discuss the material in real time. Too much gets lost in print. Another said she would have welcomed a group project to get to know the people she was posting alongside each week. And the student in my Philosophy of Education course who closed her evaluation with a qualifier that stopped me: she would take another course with me, she wrote, especially if it were in person.

She was naming what the course could not give her, no matter how carefully it was taught. In person means a room, a shared time, and the incidental knowledge that builds between people who occupy the same space week after week. It means knowing what someone looks like when an idea surprises them. The online classroom, however well designed, cannot produce that. What it can produce is thinking across a distance: deliberate, textual, deferred.

Several students named it: the effort to be known, to belong somewhere, to feel like a cohort rather than a collection of isolated screens. At PSU right now, with the graduate students in my program already at the margins of campus life, already commuting in from jobs, families, and lives outside the institution, the online classroom compounds existing isolation. That is not a pedagogical problem. It is a social one.

And yet the evaluations keep returning to learning itself — not just the longing for presence, but evidence of learning. One student wrote that the course “gave me language for what constitutes good or bad leadership” and then named the exact moment it landed: two colleagues retiring that summer, two new leaders arriving, and suddenly the concepts she had worked through in discussion posts became a lens for reading her own institution in real time. Another wrote that she had “not yet in my studies read about some of the most significant influences on critical theory, such as Paulo Freire and bell hooks.” She encountered them for the first time in this course. For those for whom the asynchronous pace creates more time, which the classroom rarely affords, it may have enabled it.

The distance is still there. I have followed someone’s intellectual development for eleven weeks without ever hearing her voice. I know how she thinks about Freire or Dewey. I don’t know what her face does when an idea surprises her. Derrida’s provocation was never that presence is lost and we should mourn it. It was that pure presence was always an illusion: that the distance between professor and student, between intention and reception, was always there. The online classroom renders the illusion untenable.

What remains, on both sides of the screen, is the effort to connect. The attempt to reach across what will not close. That may be the most honest description of teaching we have: whether the room is made of bricks or pixels, whether the students write to ask where the syllabus is posted or linger at the door after class. The effort is the same. The distance is the same.
