It is with glee that the proponents of e-learning trumpet the results of studies such as the US Department of Education’s Evidence-Based Practices in Online Learning: A Meta-Analysis and Review of Online Learning Studies, which found that, on average, online instruction is as effective as classroom instruction.

And who can blame them? It is only natural for evangelists to seize upon evidence that furthers their cause.

But these results mystified me. If humans are gregarious beings and learning is social, how can face-to-face instruction possibly fail to out perform its online equivalent?

That was until I watched Professor Steve Fuller’s Humanity 2.0 TEDxWarwick talk in Week 3 of The University of Edinburgh’s E-learning and Digital Cultures course.

The professor explains with wonderful articulation how difficult it is to define a human.

Sure, biologists will define humanity in terms of DNA, yet they can’t even agree on whether the Neanderthals were a subspecies of Homo sapiens or a separate species all together.

If we remove our gaze from the electron microscope, we have our morphology. Perhaps a human is an organism that has five fingers on each hand? But does that mean someone who is born with four (or six) is not human?

Perhaps a human is an organism that uses tools? Well, vultures drop rocks onto eggs to break them open.

Perhaps then a human is an organism that uses language? Whales might have something to say about that.

It is an intriguing conundrum that has occupied our thoughts since anyone can remember.

In the 17th Century, René Descartes made an intellectual breakthrough. He contended that “reason…is the only thing that makes us men, and distinguishes us from the beasts”. In other words, we are the only creatures on God’s earth capable of rational thought. I think, therefore I am.

Descartes pushed his point by arguing that while a robot might one day be developed to speak words, “it is not conceivable that such a machine should…give an appropriately meaningful answer in its presence”. And despite astonishing advances in artificial intelligence, the philosophical Frenchman remains right. Even Watson, who triumphed at Jeopardy! and today mines big data to help humans make better decisions, can not reasonably be considered a human itself. It is simply a product of computer programming.

Speaking of machines, if a human were to progressively replace her body parts with robotics – hence becoming a cyborg – at what point does she cease to be a human? According to the humanist tradition of Descartes, the absolute difference between a human and a non-human is a property of the mind. So, arguably she will remain a “human” until her brain is replaced.

But that begs the question: if we flip the scenario around and place a person’s brain in a robot’s body, does that make it a human?

All this philosophy starts to do my head in after a while, and that’s before getting into Freud’s posthumanism.

Somehow I prefer Joseph Gliddon’s simpler definition of a human: something that drinks coffee.

It’s not as flippant as it sounds, for it is our artificial enhancements that paradoxically make us more human.

Riding a bicycle, for example, is a quintessentially human endeavour. No other creature does it. Yes, a monkey might do so in the circus, but the reason we find it funny (or at least unusual) is because it doesn’t normally do that. The poor thing is mimicking a human.

Similarly, digital technology is an extension of our notion of humanity. Humans are the only organisms that use computers, surf the Web, write text, film video, record audio, and engage with one another in online discussion forums.

So when we view online pedagogy through this lens, we recognise very little of it that is not human. Consequently the strong performance of online students becomes less mysterious. In fact, it becomes expected because, just as a bicycle enhances our capability for travel, digital technology enhances our capability for learning.

This expectation is supported by a further finding of the Department of Education’s research – namely, that “blends of online and face-to-face instruction, on average, had stronger learning outcomes than did face-to-face instruction alone”. In other words, students who had the technology via the blended design performed better than those who didn’t.

But it doesn’t work in reverse: “the majority of…studies that directly compared purely online and blended learning conditions found no significant differences in student learning”. In other words, those who had the face-to-face interaction via the blended design performed no better than those who didn’t. Apparently the online instruction was human enough.

OK, on that bombshell, I think I’ll ride my bike to the cafe and pick up a cup of joe…
