Clayton Christensen is a professor at the Harvard Business School and the author of a widely used book on innovations in business titled The Innovator’s Dilemma. Published originally in 1997, with the subtitle “when new technologies cause great firms to fail,” The Innovator’s Dilemma went into a second edition in 2000 with a new tag line, “the revolutionary bestseller that changed the way we do business.” I note further editions published in 2003 and 2006. Clearly there is something here that has been of interest in the world of business schools and businessmanagement.

Christensen is an expert on Silicon Valley, its changing products and fortunes, but in his new book, written with two colleagues, he draws on the history of many other fields of business enterprise, from making automobiles and radios to launching new kinds of investment opportunities. His central idea is there is a kind of “disruptive innovation” that causes great companies to fail and new start-ups to replace them. Here he applies the theory of disruptive innovation to the field of education. What can we learn from this transfer of tools of analysis, apparently helpful in business, to education?

Christensen sets the stage by asking why it is so hard to improve schools, running through some common explanations: We don’t spend enough money on them, we don’t use enough computers, students have become lazy and media- and game-addicted, schools are just too traditional. And then there are the teachers unions. While he accepts that all may play a role in school failure, he sees another as the central problem: education and schooling are not childcentric and in particular do not respond to the reality that children are different and learn differently. He is a strong advocate of the work of Howard Gardner on “multiple intelligences,” supporting Gardner’s theory that there are many kinds of intelligence, and many ways of learning, and that different children bring different kinds of intelligence to the learning endeavor. Thus, according to Christensen, the traditional classroom, with children of a given age being taught by a single teacher using a common pedagogy, will not do. Effective reform requires “customization” of the process of teaching, to adapt to the varying styles of different children. And the way to attain this new model of education is through the computer, with its ability to present a nearly infinite variety of ways of teaching in almost any field. But standing in the way of such a transformation is the fixed structure of the school, the age-determined set of classes, slotted into a curriculum where one learns certain things at a certain age and must move on to the topics determined as suitable for the next year.

“Disruption” of this pattern is required, and Christensen leads us through his theory of “disruptive innovation,” which he contrasts with “sustaining innovation.” “Sustaining innovation” is one improvement after another in a given product—the automobile, the telephone, the business computer—which the product innovation departments of established companies introduce. But there is another kind of innovation, which the established companies do not recognize, or do not consider profitable, or cannot fit easily into their established patterns. Christensen offers many examples from business history: the large business computer was displaced by the personal computer, the fixed radio set by the small transistor-driven portable. Leading corporations were blind-sided by these disruptive innovations. This is what education needs if we are to see improvement (see “How Do We Transform Our Schools?” features, Summer 2008).

Are charter schools this kind of disruptive innovation? Teachers unions and public school systems think so, but they will not quite do for Christensen, though he recognizes some as being truly innovative. Does the huge expansion in the number of computers in schools serve as an appropriate disruptive innovation? It could, but it doesn’t, because they are used primarily to supplement old practices rather than establish the new ones that are truly disruptive and innovative. The truly disruptive innovation, according to Christensen, is one that is directed to the nonconsumer of the established product. This seems to be a key feature of his theory: The small personal computer did not supplement the large business computer of the early days of the computer revolution, but instead served those who didn’t have any computers at all; the transistor-driven small radio was embraced by those who had no other access to radios.

But how do we apply this story, based on histories of business successes and failures, to schools? By way of Gardner’s theory of multiple intelligences and the computer’s capacity to provide different ways of teaching and learning. Christensen heads each chapter with a vignette featuring students, teachers, and administrators in an imaginary high school. In one of these vignettes Maria, an able student interested in learning Arabic, which is not offered in the school, is directed to a computer program and shown happily learning the new language. This is an example of the “nonconsumer”—this student was not already taking Arabic, though she may have been studying another language. Rob is an able athlete—an example of Gardner’s “bodily-kinesthetic intelligence”—who is having difficulty with chemistry. He also gets connected to a computer program, which teams him up with a Japanese student who is eager to learn English and will in exchange help him with his chemistry. One is less optimistic that this approach to improving chemistry for Rob will work as well as the Arabic program for Maria. One wonders, too, whether there is any kind of specialized computer program imaginable that will make use of bodily-kinesthetic intelligence to improve knowledge of chemistry.

Christensen is aware of the strong class differences among children as reflected in school achievement, but he is convinced by research that shows that a great part of intellectual ability is determined by the experience of the first 36 months of life, particularly the amount and kind of language directed to children. Nothing much can be done about that when the children reach school, even in pre-kindergarten, so he puts his money on multiple intelligences and the computer.

Christensen acknowledges the many problems that are involved in what he hopes will be a revolutionary change in how education works, when many kinds of imaginative computer programs addressed to all kinds of students are in use. The lockstep system of education is bolstered by many institutions, such as the production and adoption of widely used uniform textbooks, and Christensen hopes that they will be undermined by the rapid advance of computerized teaching programs, adapted to different children. He sees opportunities for this kind of disruptive innovation in the small rural schools that cannot offer many subjects, in urban secondary schools in low-income areas with similarly restricted course offerings, and for homebound and home-schooled students. He sees the beginnings of a market response in companies such as Apex Learning, established by Microsoft cofounder Paul Allen. Enrollment in online-delivered courses rose from 45,000 in 2000 to 1 million in 2007. From a perspective based on the experience of innovative growth in other areas, Christensen writes that “the data suggest that by 2019 about 50 percent of high school courses will be delivered online.” This is an astonishing projection, and one doesn’t know what to make of it. Is it really possible? Christensen shows a surprising self-confidence on other matters as well. Critical of contemporary education research, he touts an approach which seems not particularly different, but from which he expects great results. “Other fields,” he writes, “have bodies of research that allow people to predict with great certainty the results of actions.” “Great certainty?” I wonder.

Disrupting Class breathes a degree of confidence that is on the whole foreign to the world of education, one that may be characteristic of the world of the business school. In business case studies, one learns just why businesses succeed or fail, and the course of action that would have avoided failure. In the world of real business, things are of course not so simple. Undoubtedly more, and one hopes better, use of computers will be made. Perhaps they can be adapted to different styles of learning. Christensen envisages this as emerging from “user networks” developing “user-generated content.” That certainly seems more feasible, if it can be done, than the enormous up-front expense incurred in developing a large array of courses adapted to different kinds of students. But one cannot resist a degree of skepticism. What we have learned to value in schooling is verbal and mathematical skills, and perhaps we have been excessive in the degree to which we value the kinds of intelligence that lead to high achievement in these competencies. But such achievement cannot be attained by every style of intelligence, using distinctive means adapted to it. So I remain skeptical of the prospects for “disruptive innovation” in our education system if its success will rely on heightening the role of other kinds of intelligence.

You read about it all the time—the writer who wrote her entire novel in stolen bits of time. In the car while her kids were at gymnastics class. In the early morning, before anyone else was up, when the day was only hers. While waiting at the doctor’s office. In a coffee shop between meetings. You read it all the time—a page a day equals a novel a year. Seems easy enough, right? So why aren’t we all writing that novel a year?

Three things come to mind to me. For me. Perfectionism, pressure, and procrastination. We all have different reasons why we don’t write. These are three of mine. I am a wild perfectionist. If I can’t do something right, I’d prefer not to do it at all. Either the house is sparkling clean or there are, as my husband calls them, explosions everywhere. Either I read the book in three days or I don’t pick it up at all. It’s exhausting, really. I believe I MUST commit to four hours a day of writing. It’s unreasonable. Sometimes we don’t have hours. I build it up, you know, convince myself I am not a real writer unless I have a structured writing schedule and produce 1,000 words a day. And then there’s Pressure which is Perfectionism’s evil cousin. I must finish the story. I must finish the story and it must be the best story I’ve ever written. I must write something meaningful, beautiful, touching. I must finish this novel by May. If I don’t finish it by May, then I’ve failed. Pressure. The stress of it breaks you down and then you Procrastinate. You procrastinate because how can one possible be capable of all this? It’s just too much and the task is too daunting so you empty the dishwasher instead. You do other work, work that could have waited. You call people. Hello, hello, you say, you ask them what they’re doing, what they’re eating, if they’ll come save you from your misery.

We all have walls, you know? We all have our things. Whatever they are, we can’t let them get in the way of our goals. Procrastinating, for me, is draining. William James said: “Nothing is so fatiguing as the eternal hanging on of an uncompleted task.” It’s so true. The weight of it in your mind, the project you so badly want to complete, and know you can complete. There’s that blank screen staring at you, a reminder of the undone. And then suddenly you are a big fat failure. You didn’t write today, yesterday, or the day before. It’s too late. Forget it. You’ll never write again. And while all this is highly dramatic, there is one truth: That there are a million ways to lose a work day, but not a single way to get those days back.

I’ve realized these things about myself. I’ve realized those three Ps are going to try and stand in my way. And by realizing it, understanding it, I win half the battle I think. We have good days, bad days. My best friend said this to me over coffee and egg and cheeses the other morning: I am finally able to appreciate the ebbs and flows of life.  I, too, am trying to appreciate, embrace, the ebbs and flows of a writing life. Some days we write well. Other days we just write. And so my ongoing mantra has become this: Ten minutes of writing is something. Bad writing is something. Something is better than nothing.

And it gets easier. Thank goodness. You write for ten minutes and suddenly you’re into it, you’re rolling, going, inspired. You want to write more and realize how easy it is once you just get started.

I also plan to buy a new notebook, something I can carry around with me so I can catch some words on the page during those stolen bits of time.

Writers write. Butt in chair. It’s that simple.

What are your walls? Your things? What keeps you from writing?

“Action and reaction, ebb and flow, trial and error, change- this is the rhythm of living. Out of our overconfidence, fear; out of our fear, clearer vision, fresh hope. And out of hope, progress.”
