If We (Profs, Teachers) Can Be Replaced by a Computer Screen, We Should Be!
It's meant as a challenge, not a prescription: "If We (Profs) Can Be Replaced by a Computer Screen, We Should Be! I am amazed at how often my pronouncement, made most recently at the Harvard Innovations in Learning and Teaching (HILT) Symposium, is interpreted to mean "All profs should be replaced by computer screens." Not at all. What I mean is that, given how sophisticated online technologies are becoming, given how many people around the world are clamoring for quality and low-cost education, given how seriously people in the online educational business (like Kahn Academy) are studying how people learn and what kind of help and interaction they need to learn, given all that, then, if we profs are adding no other value to our teaching but that which could be replicated on line, then, well, turn on the computers and get the over-priced profs out of the classrooms now.
But do I think what great teachers (great ones) do can be replicated by online educational forms? Not at all. Do I think great teachers are over-priced? Not on your life. We're a bargain. But we have to take seriously that subjunctive "if" and we have to take seriously what it means to redesign learning for the 21st century, a world where, indeed, we and, more importantly, our students are constantly competing in a world of outsourcing and mechanizing. If we are not understanding this workd and adding something that only great teachers can add, we should be replaced.
What is the case for face to face teaching? First, it is precisely the condition of being face to face. Great teachers know how to take the temperature in the room, and see how to take the experience of a diverse group of students learning together and transform it into something magical (at its best) and irreproducible mechanically. There is a quality of the human and aspirational and inspirational that defines teaching and that is something that happens when I am in the same room with you. Great teachers understand how precious face-to-face communication is and find ways to make the most of our very special time together. Great teachers understand the intimacy and responsibility of great learning, of how charged and fraught and precious the role model and mentor are. They treat that human relationship with the utmost respect and care.
More than one person has said the really important 3 R's are "rigor, relevance, and relationship." A great teacher does all three, setting the standards sky high, making sure that the learner understands how all that hard work will translate into life-forming knowledge or values (what Anthony Appiah recently called the most important aspect of learning, helping us to think about "how we want to live our lives"), and ensuring a personal connection that, in essence, models the way to translate that rigor and relevance into something intensely meaningful and motivating.
I'm not sure any of that can be replaced by a computer screen, at least no screen I've yet seen.
But how many of us take the injunction seriously? In a world where lots of learning can be taught online, we better think seriously and carefully about our particular role in the classroom or we will be put out of business and perhaps we should be. I've learned how to Moonwalk from an online tutorial. I'm learning how to draw from online courses. I'm learning Java Script on line. I have a list of other things I'd like to learn. Millions of others share my desire to learn when we can, in airports, on runways, on weekends, fit to my schedule. If I am taking the time to schedule a class meeting, I want it to be meaningful. No phone-ins, please!
Here's a method of "mixed" classroom instruction that feels right for now, and please note how little of it is about interaction, not just about content. In the very best pedagogy that takes advantage of online instruction, the remarkable affordances and mechanics of learning online are coupled with individualized, creative, inspiring human instruction. There is, for example, a marvelously interactive algebra program that is problem-based, not memory-based, where kids are given simple problems and, when they pass those, the online instructional program than gives you a slightly harder one or one with a twist. If you pass two or three of those, it then takes you to the next level, constantly intermingling conceptual explanation with problems to be solved to get to the next part of the explanation, so the testing isn't extrinsic but actually incorporated into the learning process. More to the point, for the teacher, there is no need for end-of-subject testing because, at a glance, the teacher can see how far a student has gotten on her own and where she's stumbled. Classtime then is spent with very small clusters of students, each cluster chosen because of a problem, and with other clusters working together during that same time on a different problem that they are helping one another to learn. When the teacher focuses on them, they can they show if they've solved it or not by talking about how they answered the next series of questions and on and on.
This is the opposite, conceptually, of "dumping technology in schools." It is a thoughtful combination of the best forms of online and human teaching. The combination of brilliant (and non-profit: that is essential!!) online calibrated, challenging, fun problem-based learning, indvidualized instruction with embodied, personal, affective teacher attention, and with peer-group learning motivated by both the teacher and the technology seems to me to be an ideal model. It's rather like chess master Kasparov saying "yes a computer can beat me now----but who can beat me playing with a computer I helped to program? Bring on our competition!"
How do we learn best? How do we teach best? That's the question. If we can be replaced by a computer screen, we should be. If that statement worries you, well, maybe that's a good thing. It's a challenge. It's meant to provoke thought about what we can add, or how online learning can take care of certain basics but there are other, even more foundational basics, that require real, human, interactive, meaningful connection. That's the point. There's no one model, there's no right way. But there are plenty of lazy, unthinking wrong ways. That's the challenge. That's the choice. IF we can be replaced by a computer screen, we should be.
