As someone who enjoyed her twelve years in the American public education system and believes that there is no higher calling than becoming a teacher (and does not work in education), I found this book to be fascinating - it challenged my long-held views about learning and teaching - and encouraging - which I was not expecting, given the current dismal state of so much of the American public education system. Yet Disrupting Class was a refreshing read and it has created a new discourse on a familiar topic: how to improve the American public education system.

Professor Christensen's theories of disruptive innovation are cogently explained for the unfamiliar and for those who need a refresher (like myself). The theories and their corresponding case studies are fascinating in and of themselves (think a cliff notes version of Christensen's previous books). The breadth of industries they cover creates a compelling argument to not only allow for but to encourage disruption in public education.

The authors' scholarship in innovation is evident; their prediction of when student-centric technologies (the disruptive innovation) will take hold is not conditional, rather, it is absolute: "by 2019, 50 percent of high school courses will be delivered online." I admired the authors for their willingness to walk the reader through the s-curves and logarithmic axes needed to reach this conclusion - to me, it was one of many instances in which the authors, an eclectic trio, bridge the often unnecessarily wide gap between the "business world" and the "education world." I was left wanting more detail about these "student-centric" technologies that would teach to Gardner's different intelligences but also appreciated that the authors kept to the bounds of their expertise and research.

America has struggled for years to improve public education from the top via government policy. Allowing for change from the bottom presents less risk and a lower cost of failure to the existing system. A solid understanding of Christensen's theories has brought great success to its adopters (and failure to those who have ignored it) in such a wide range of sectors that it seems almost irresponsible for anyone who cares about education to not read this book.

Disrupting Class doesn't have all the solutions, nor does it claim to. What this book does offer is a new framework within which to think about creating positive, lasting change on the type of scale needed to be meaningful and suggestions on how to realize this.

Read this book and learn the language of disruption and why simply buying more computers, aka "cramming" doesn't work. Be inspired by the work of companies such as Apex Learning, Florida Virtual School, and K12, and start your own dialogues about new student-centric technologies that will revolutionize the way the next generation learns.

"Disrupting Class" is a very interesting read for people interested in improving education here in the U.S. Dr. Christensen argues that the main problem with traditional schools is that they cannot provide individualized instruction that best meets each student's needs. As a home educator, I couldn't agree with him more. He sees computer-based learning as a "disruptive innovation" that will solve the problem of how to provide this type of "student-centric" learning to the masses (since not everyone can homeschool or hire a tutor for their offspring).

Dr. Christensen revisits the argument from his earlier book "The Innovator's Dilemma" that "disruptive innovations" don't initially compete directly against the current market leader's product but rather against nonconsumption. For example, in the '70's Digital had a very successful market for $200k minicomputers. Apple couldn't directly compete with DEC's minicomputers because their personal computers weren't good enough at the time to solve the problems that DEC's customers had. So Apple marketed its IIe PC as a relatively affordable toy for kids. Kids were nonconsumers so it didn't matter to them that the Apple wasn't as powerful as the existing DEC minicomputers. A few years down the road, however, improvements in PC technology rendered DEC's minicomputers obsolete.

Dr. Christensen argues that the traditional government-run education system will in the near future be "disrupted" by the innovation of computer-based learning. At first, online learning will compete against nonconsumption by offering classes in subjects where there isn't enough demand in any given school to justify offering a traditional course (such as a very advanced math one or an unusual foreign language). But eventually, He believes that the technology will improve such that computer-based learning will render the traditional model of education obsolete.

In "Disrupting Class", he postulates that demand for computer-based high school classes will follow an S-curve that will start to "flip" (significantly accelerate) in the year 2012. In the years between 2012 and 2018, Dr. Christensen projects that the share of online courses will grow from 5% to 50% of all high school courses. That timetable seems a bit ambitious to me personally, but I believe he's got the basic right idea about the growth in the demand for online classes.

The main problem I had with "Disrupting Class" is with the way it is written. It reads like a management consultant's report filled with buzzwords and jargon (not surprisingly Dr. Christensen used to work for BCG). It would've been much better had someone else gone through the authors' draft and re-written it in plain English. I found it very tiresome to have to stop constantly to figure out what exactly the authors actually meant by all their convoluted gobbledygook. Throwing buzzwords and jargon into nearly every sentence doesn't make the authors look smarter, just much less coherent!

The other thing I would've liked to have seen discussed in "Disrupting Class" is the question of whether or not it is good for children's brains for schooling to be mostly computer-based. Dr. Jane Healey wrote a very interesting book about a decade ago called "Failure to Connect" about some worrisome research findings on the negative impact of computer use on children. Has more recent research allayed or deepened those concerns? Before our society makes the shift predicted in "Disruptive Class", shouldn't we be examining this very important question?

Any prospective reader of this book should first read Hubbard's How to Measure Anything: Finding the Value of "Intangibles" in Business (for that matter, Christensen would have written a better book if he read Hubbard, too). Christensen rightly disputes some academic measurements, but too quickly dismisses better methods.

Apart from what he could have done better on the measurement issue, he makes a passionate case for getting out of the rut education finds itself in. Some of the recommendations might strike a business person or educator as a little impractical, but I think there is an interesting opportunity in every solution he proposes. True, there is a large genre of books about the need for change in education, but few take this angle. No educator's library should be without it.

Christensen approaches improving the education system from the broad lens of innovation, rather than focusing solely on examining the school system itself. The result: a powerful perspective on how disruptive innovation outside the mainstream curriculum can ultimately transform the techniques and results of the public school system in general.

Disrupting Class outlines a thorough argument for how to dramatically improve the U.S. educational system including:

* The shortcomings of previous approaches to improving education, and therefore what needs to be different in the future

* The importance of adapting teaching techniques to different learning styles (building on previous work Gardner and others); I can particularly relate to this as I have a family member with dyslexia who became an avid reader after receiving a different approach to reading instruction rather than the standard public school curriculum.

* The potential for computers and more modularization of teaching to deliver individualized learning in the context of the school system; Christensen is quick to point out that more computers are not the solution, it is the way in which computers are used that are critical.

* The barriers to change in the current system; Having studied numerous organizations within and outside the educational system, Christensen presents a valuable framework for how to drive change in organizations with different characteristics. The challenge is that the public school system has one of the most complicating set of features. Through understanding these factors, administrators and educators must employ different approaches to creating change which are outlined in the book.

* The need for innovation in areas outside the mainstream elements of the educational system (the book draws on the principles from Christensen's previous work, The Innovator's Dilemma); He cites examples from outside and within the educational system and illustrates how "disruptive innovation" around the fringes can ultimately redefine the public school system as we know it today.

In addition to having a compelling thesis, Disrupting Class is also an easy read. Christensen makes it come alive through weaving a narrative throughout the book of a public school principal struggling to make a greater difference in her students' development.

While the book overall is excellent, there are two sections which could have been shortened without detracting from the overall story. The first is Chapter 6 which makes the case, largely based on the research of others, of the importance of learning in the first 36 months of development. While I found it compelling and causing me to wonder if I had done enough for my own children at that age, I did not find it added much to the overall thesis. Similarly, Chapter 7 discusses the need to change the research approach in the field of education improvement. While it may be useful to some educators as they evaluate options in the future, I found it less engaging than the other chapters.

Overall, Disrupting Class is a must read for those interested in education from any perspective - parent, educator, administrator, politician or non-profit organization. As someone who is a parent and involved in a non-profit in the education arena, I find this book incredibly energizing - it has given me some ideas for innovations to test in the non-profit context alongside the public school system. I encourage you to read it and find ways to apply the lessons in your environment as well!

I am a layperson with an interest in education and technology. I read Innovator's Dilemma and was anxious to see if Clayton Christensen could apply his unique business lens to sort through, and perhaps solve the issues concerning our failing public education system.

He and his colleagues didn't disappoint me.

This book was eminently readable and layer by layer, uncovered the weaknesses in the way we educate our kids. It's not simply a matter of putting technology in schools or tutoring kids who learn differently; it's a matter of changing the way the monolithic system, and entrenched stakeholders, work against innovation and creativity in learning by challenging the underlying foundations of that system.

According to Christensen, flexible individualized instruction combined with the proper use of technology, rewiring content development and distribution channels, and the creation of online networks of students, parents and teachers working together instead of in opposition, can revolutionize education in the United States.

If you care about the future of education, and of a child's ability to compete in the global economy, read this book.

The earlier books on innovation, and especially The Innovator's Dilemma: The Revolutionary Book that Will Change the Way You Do Business (Collins Business Essentials), are better. I strongly recommend that you buy both the above book and this book to have a larger understanding.

The book reads like a Harvard case study fleshed out from 40 pages to 230.

The book has exactly one bottom line: that self-paced instruction using online learning and (this is the cool part) interaction with other languages and cultures (e.g. connect an Arab learning English with an American learning Arabic), is the only way to introduce flexibility. It is this human dimension that carried the book to a four for the US audience only.

Everywhere else in the world they substitute discipline for technology and do quite well. I was troubled by the book/s very narrow focus. There is no consideration in this book, for example, of any of the following (just one example per literature category):

Don't Bother Me Mom--I'm Learning!
Teaching to Transgress: Education as the Practice of Freedom
The Landscape of History: How Historians Map the Past
Fog Facts: Searching for Truth in the Land of Spin
Weapons of Mass Deception: The Uses of Propaganda in Bush's War on Iraq
The Cultural Creatives: How 50 Million People Are Changing the World
Idea Of A University: Philosophy (Notre Dame Series in the Great Books)
Forbidden Knowledge: From Prometheus to Pornography
Collective Intelligence: Creating a Prosperous World at Peace

Flyleaf notes:

+ Need to migrate from monolithic "one size fits all" methods (meaning teacher talks, all listen, or "didactic instruction" to student-centric technologies (my note: rather than human scale and practice)

+ Ages 0-4 are where the child actually learns all the self-confidence and other characteristics needed to succeed down the road (but no real discussion of this and how computers could help, that I saw)

+ Schools are too standardized, need modularity and flexibility (of course this is what the last two generations, and especially Generation 2.0, have been telling us--schools beat the creativity out of kids by the fourth grade, and today the best student drop out of high school rather than sit still for another two years).

+ They give Gardner full credit for discovering multiple intelligences, but they lost me a second time when they focus only on technology as the innovative solution, and fail to properly develop the theme for art, music, theater, social work, apprenticeships, and etcetera. This is a book with one simple message and focus on computers in the US classroom.

+ Schools have four jobs (none of them actively discussed in dollar and cents or program planning terms):
- Preserve democracy, inculcate values
- Provide something for every student
- Keep America competitive (ha. China graduates more HONOR students than we graduate students across the board)
- Eliminate poverty (this is a bit lame, reflecting no appreciation for structured inequalities outside the classroom, as well as political disenfranchisement and banking fraud including red-lining for future development profit).

The authors repeat one of the pearls of wisdom from The Innovators Dilemma (link in first line above), and suggest that those who wish to innovate should go after those not served, citing Apple's genius in offering its early computers as toys for children.

+ Four factors are in favor of innovation (in US schools):
- Computer-based learning keeps improving (see Don't Both Me Mom, link above, that book ends with recommendations for learning programs across the board that are online now)
- All can select pathways (this assumes they have been taught discipline and curiosity someplace along the line)
- Looming teacher shortage (I agree--advanced child care and factory worker angle are history--we need to learn to learn in all places)
- Costs fall significantly as market scales

They spend too much time on three business models, my first hint this might be a Harvard Case Study in book form:
- Solution shops
- Value chains
- Facilitated user networks

I write down from the book "best to combine disruptive business model with disruptive commercial system." I have no idea what this means. From the poverty literature (see my lists), I received the idea of hybrid organizations, non-profits that catalyzed profits sufficient to attract foreign investment, e.g. low cost nutritious yogurt for children in India). Perhaps that is what they mean, I concluded after reading this twice that maybe they meant go after those not served *and* make it free at first (upgrades can cost).

Harnessing user-generated content is a key idea that may not be noticed. It is in fact the foundation for Web 2.0 and I expect the human factor will continue to scale in importance and the cost of technology declines.

The book ends weakly, with disappointing coverage of the 0-4 age or on educational research needed. They conclude with short messages for various stakeholder groups.

I went back through the book a second time, and would note that there are some very clever useful visualizations in the book, especially Figure 8.2 on page 187, and these alone are worth the price of the book.

In the end for me, the book was worthwhile but could have so much better if they had started with innovation ideas for each of the stake-holder groups they address in ending. The five billion poor are never going to be educated in a classroom, but we *can* give out free cell phones and create two call centers, one in China and one in India, that combine Internet access, Skype free telephone access, and access to a global network of 100 million or more volunteers able to answer any question in any language, free, at the time of it value to the poor person asking the question. THAT is world-class innovation because it creates infinite wealth, and does not limit itself to justifying charter schools because they can buy more computers.

Clayton Christensen has gained fame in researching how disruptive technologies are best brought to market in the world of business. He applies the results of this research to hypothesize how education methods uniquely tailored to each student through the use of computer led education are likely to be adopted.

The key observation that Professor Christensen makes is that each student has different intellegences, including linguistic, logical-methematical, spatial, kinesthetic, etc. The classroom, by being forced to standardize on a teaching method for a particular subject, cannot appropriately adapt the teaching of each subject to the learning and intelligence patterns of each student. Computer-based education can overcome the standardized approach, however. He argues that the adoption of computer-based education as a supplement to the teacher led classroom is not the likely path of successful adoption.

The book is written for government officials, teachers, administrators, parents and entrepreneurs. It is probably most valuable to entrepreneurs who are exploring the market for user generated educational content.

As I see it, every American child is indoctrinated into our society through about 30,000 hours of instruction. Over a dozen years, they sit in school for about 15,000 hours and they consume media for about 15,000 more. Often, the learning is conflicted, and, for many students, the system fails.

Authors Clayton Christensen, Michael Horn and Curtis Johnson focus on disruptive innovation as a means to change to change schools and change our system of learning. Their focus is institutional change, and their approach is not difficult to understand. In essence, they illustrate why and how established institutions find innovation so challenging, and why disruptive innovation is more likely to be successful when it comes from outside the established institutions. (This concept applies to many types of institutions, including media organizations.)

In this book, the future of education is aligned with a new kind of media industry, one that connects individual students with self-paced, highly interactive educational media. The authors focus their future vision on software and connectivity; I think the view should also embrace a wider range of media, including some new form of short-run publishing (print has its place), television, video, live performance, and a richer array of human interactions. But we fundamentally agree: individualized instruction, self-paced, utilizing rich media so that all instruction is self-paced and evaluated during (not after) the learning process--these are the right ideas. And, we fundamentally agree that schools and school systems are not likely to change their ways. They must be disrupted in a significant way.

Now, there's a guidebook for that radical change. The next step is to educate enough people in the ways of innovation so that the disruption can take shape. I'm in. Please read the book, and if the ideas feel right for you, join the revolution.

Rocket Builders most influential author, Christensen, with his co authors has taken his theory of disruptive innovation and focused on the education sector. The authors do not lay blame but with Christensen's laser sharp analysis, peel back all the root causes of public perception and changing goal posts for education and what it has done to the institution over time. He then goes on to explain how classic disruption theory - which starts with non consumers and then slowly moves up the competency level as the incumbents are forced to retreat to higher value activities is already progressing in education. He predicts that by 2020, disruptive innovation will hit that 50% mark to turn the tables on other methods (monolithic education in this case) . They show how trying to bring the disruption inside present institutions can not succeed due to the constraints that are already in place. His statements ring true as we have seen the impact of disruption on public and private sector already.

Since his team always does their homework, you are exposed to fascinating research on the impact of verbalization on new borns up to 3 years old. They explain how that is an academic headstart any parent can give their child now. He posits that early kindergarten (after 3 yrs old) and other high priced interventions are doomed to a limited success rate. As well he quickly exposes the paucity (weak techniques and theory) of real research in education since it all to often stops short of causality ( I can certainly testify to that) . Then he explains how computer based education methods are already changing and adapting to the needs of a student centric model. He illustrates how Howard Gardners multiple modes of learning could be accomodated in the disruptive model.

Once again there is a second book within the book with copious research notes in every chapter. I am one of those professional educators who packed it in based on what I experienced as the overall futility of real change in education. Now this book has reawakened my interest in change in the education market - moving to a student centric model. If you have children or grandchildren - you need to buy and read this book. If you are in the e-learning market - it is required reading. Thank you McGraw Hill! I really liked it and it is as always an easy read with loads of detail if you want it.

Administrators, teachers, parents, and policy makers would do well to read Disrupting Class. The authors approach education with the perspective of an outsider - business person, technologist, entrepreneur - but the knowledge and thoughtfulness of an insider. Instead of offering didactic or hubristic "fixes" for education, the book provides a framework for thinking about education that is fresh and practical, particularly on such issues as how technology can personalize education for the needs of each student, and most importantly, how disruptive innovation can overcome the many obstacles that have heretofore prevented reforms in the US education system.
