Efforts start with individuals and off-hand I can think of at-least 2 which I myself practiced and provided me a sense of achievement:
For those in Pakistan, take responsibility for at least one child from the 'less privileged' class (possibly your domestic help's kids) and try to provide 'better' education by yourself, your kids/siblings or sponsor his/her quality tuition.
For those abroad, try and develop curriculum for school level courses keeping in view the shortcomings of our own and their experience with schools in the developed world and share that with resource stretched private schools in Pakistan (government schools won't follow it and rich private schools can buy it).
1 - This would be a good charitable way to boost Pakistan's literacy rate. You would probably find most support for this kind of initiative in cities.
2 - The rudimentary issue with this would be you first need to board exams changed at HSC and SSC level. They are formatted such that foreign curriculums cannot succeed. Most of the books taught in private school are foreign and less from pakistani authors. However what I am focusing here on is the change we need in methodology for educating Pakistani children. And the impact it would have on their psyche. It needs to be used as a massive vehicle for change.
