The primary function of a school is to produce educated and productive citizens. The emphasis in the American school classroom is on producing students able to think for themselves, and develop critical analytical skills, by engaging the students in classroom discussions. In Pakistani schools, there is significantly less student-teacher interaction as the bland lecture method is the preferred means of instruction. The emphasis is certainly on keeping the student's mouths and minds shut, in Pakistan. Anything outside the four corners of the assigned textbook is heresy, and not open to discussion.
Rote memorization is the order of the day, even in the best of schools.
Imagine the impact of sex education in American schools and constant lectures of having safe sex. Moral values are best imparted by the family, no matter where one lives. I must say that what I find truly abhorrent, is his attitude seemingly condoning ignorance. Cultivating ignorance about sex is certainly part of the reason why many uneducated women in Pakistan bear seven or more children during their lifetimes. In Iran today, before obtaining a Nikahnama, couples are required to attend a short family planning course together.
