How bored do you get of these studies? everywhere I look somebody else is telling me that 'the winds of change are blowing'... 'theres a revolution happening'... 'blink and you'll miss it' type thing. I think this is a little obvious. Telephone changed things, computer changed things, mobile changed things, internet changed things, internet on mobile will change things. I WANT FACTS - HOW, WHY, WHERE, WHEN, WHO'LL PROFIT? come on guys, let's get specific. Posted by Alex

TECH TALK: Let's Build a Business: 2. Education
The ideas for the education venture are from Atanu Dey. The Indian education system is in distress. It is critically in need of reform since it is inefficient and ineffective. What exists today is something that was designed to serve the needs of a different era with different objectives and compulsions. For sustainable development of India, the country needs a new system which is economically efficient, socially equitable, functionally effective, and consonant with the altered needs of the present. We have to recognize that there are severe resource constraints. There is a capital constraint, of course, but more importantly we have a human capital constraint, mainly in terms of limited numbers of trained teachers. The former can be circumvented by borrowing the required capital; the latter is much harder to overcome because it takes years (which we cannot afford) to train the millions of teachers required. To meet the challenges of the different world we live in compared to the one for which the existent educational system was designed, we have to fundamentally rethink the educational institutions. Merely tinkering with the system will not suffice. However much one modifies a bullock cart, one cannot transform it into an efficient, fast all-terrain vehicle. The fact that our age is characterized by high technology is both a challenge and an opportunity. To participate in today’s economy, one needs not only to be literate and numerate, one has also to be fully competent to use the technology. Fortunately, it is technology itself which can help in the transformation of the educational system. Here is a short list of specific problems that plague the system and a brief suggestion on possible solutions. 1. Financially too costly. If money was no object, then the tens of millions who need education could be accommodated with ease. Being costly, today a good education is affordable only to a vanishingly small percentage of the population. The costs can be brought down by substituting the most costly factor: teachers. Use ICT (information and communications technology) as a substitute for costly teachers. 2. It wastes too much time. The current system does not efficiently use time. It should not take over a decade to provide students with the basic foundations of a good education. It can be done in much less time, so that the student has more time to build upon that foundation. Greater specialization of the economy requires that the foundation be laid more efficiently so that more time is available for specialization. The recommendation is to reduce the time spent in the foundation to about 8 years and allow five years for specialization, to arrive at a fully qualified employable person by age 20. 3. Students are overburdened. The few who are lucky enough to be in school, have a pretty hellish life. They have very little free time, between attending classes, doing homework, going for “tuitions” and so on. A lot of disjointed information is thrown at them and they are never able to fully comprehend what it is all about. The solution is to reduce the amount of information that the student is fed, and instead motivate the whole exercise of learning so that the student spend more time internalizing a comprehensive coherent set of information. The system has to allow the student more free time. 4. The system is inflexible. It does not encourage creativity and does not reward individuality. The system must be made ‘student-centric’ instead of ‘teacher-centric.’ The student must have the freedom within to system to follow the path that is most natural and which is consonant with his or her talents. 5. The system is supply constrained. The competition to enter the limited number of educational institutions is fierce beyond description. In the scramble for limited seats, a very large number do not get a chance at getting an education. The supply has to be increased. 6. Credit constraint. Even after the supply is increased, individuals have to be able to afford the quality education. The returns to education are positive. Which means that those who cannot afford the education due to credit constraints are unable to get the returns of education. The solution is therefore to increase the amount available for loans and to massively subsidize primary education. Education is the master key which can unlock the potential of the nation of over a billion people. If we continue to neglect education, all our efforts in other spheres is likely to be in vain.

Pratham (pratham.org) and Azim Premji Foundation (azimpremjifoundation.org) are doing good work in this area, but we certainly need more initiatives as there is clearly so much to be done to fill the gap. Regards, I definitely don't agree with your argument that we need to get rid of teachers. The highlight of any good education system is its good teachers. If you can offer education by eliminating teachers with IT based infrastructure, you will only impart knowledge on the students. You will not educate them. I think this argument is totally flawed. I do agree with the other parts though. Posted by KrishKrish, noone is suggesting that teachers be gotten rid of. What is required is to use technology to release the constraint of lack of good teachers in the numbers required. We don't have 4 million teachers of the calibre of a Feynman or a Bardhan. What we can do with technology is to make the good teachers "available" to a larger number of students. To give an analogy: world class actors are few and therefore expensive. Bill Gates can hire them to perform "Hamlet" at his mansion. For the rest of us, we can see the movie with the same actors but at a fraction of the cost. Before movies became inexpensive enough, there were only two choices: watch a play enacted in front of you and see great acting if you are rich; and watch a play enacted in front of you and see lousy acting if you were poor. What the technology of movies did was to enlarge the set of options to: watch a play with good acting but projected on a screen. I would any day watch "Hamlet" played by Sir Derek Jacoby made at great expense at the local movie house than watch a bunch of amateurs playing "Hamlet" in the local theatre. The important thing is the expanded choice that technology provides. Teachers are critical to motivating the study of subjects. But excellent teachers virtually present can do the job better than flesh and blood teachers who barely know the subject, leave alone motivate the subject. Posted by Atanu DeySir, I find your ideas 2 and 3 contradictory. As i understand, as the time given to lay the foundation is reduced, the burden on the children will obviously increase. But i hope you will also acknowledge the fact that most of the parents in general do not realize this and go by the accepted notion of "More is Better". And i don't see parents who can afford decent education (i.e. with the current system) for their children buying your argument unless one is able to show results with the proposed new system. That leads me to conclude that what we are looking at is a Educational System which supports two full-fledged sub-systems within it. I guess after 15 years of your system in place we will have the results for the then parents to be able to compare the two sub-systems. I hope and pray your system will win then. Posted by ArpitArpit, it is possible for a system which is too costly AND slow to be replaced by a system which is cheaper AND faster. The telecommunications system today -- due to advances in technology -- is both cheaper and faster compared to the system it replaced. The lesson: wholesale replacement of an obsolete system is better than tinkering with it and making marginal changes. Will a better system be adopted by "risk averse" parents? Not necessarily and not without costs. But that the system will be replaced is not debatable. The question is when, not if. We can choose to be at the leading edge of that change and profit from it, or we can be late and lose out on benefits. The choice is ours: are we going to be innovators or followers? My guess is that given our cultural conditioning, we would rather be followers. Time to break that tradition, wouldn't you say so? Posted by Atanu DeySir, I find your generalization of telecommunications system a little unfair. I think such huge systems can only be fazed out with a simultaneous replacement with a newer version. Two very important differences in the two systems are the time it takes to see the results and the nature of impact it has on the consumer. Telecommunications : Few days or months. Nature of impact definitely reversible. So as a consumer if I don't like the newer system i always have the option of going back to the old one. Educational System : 10-15 years. Irreversible This is the point i was trying to make. I think i am failing to understand what all constitutes your definition of Educational System. Sir, please don't take my arguments as pessimism. I am just trying to clear my thoughts. One more doubt if i may. In your point 4, you say that the system needs to be more "student centric". Don't you think that the current system is more "student-centric". I mean the system is judged on student's performance. I think we need to make the system "Teacher-centric". Lets judge the system by the perfomance of the teachers. And obviously good performance of teachers means good teaching which means igniting learning.

Nearest convenience stores can become pick up points for ?online-shopped goods? for ome needs. Retailers publish items available in local stores in web. Customer chooses nearest store and buys online. Retailer delivers it to a petrol station convenience store nearest to the customer. Customer picks it up. This saves lot of time for customers in driving in urban India. Items like grocery, home electrical, easily orderable garments(hankeys, inners) can be ordered. It will also help reduce pollution and fuel consump and traffic congestion in perpetual infrastructure starved Indian cities.
I had planned to do this. But settled with an interesting Web 2.0 project.
