We have lots of good schools in the countryside, suburbs, and slums that need help in raising the level of education by change in methodology and low-cost education tools. Also, despite a lot of major changes having being suggest by respected educationists, the implementation suggested by them or radical changes in methodology found by them to be essential, the change is extremely slow. Much of this is due to inertia, and some because of few incentives for teachers to update their skills or methods.
The gap in where we should be and where we are is not only large in rural areas, but the inertia is seen even in large schools. Some of the best-known schools, considered to be extremely sought-after, could also be making the same mistakes.
