Global education is a useless scam

But the bad news is that hundreds of millions of children are starting school, going day after day, year after year, but not really learning. One study found that almost three-quarters of a recent cohort of youth in Zambia were innumerate and six of 10 illiterate. But only 7% of these youth had not attended school. In fact, half of those who were innumerate and a third who were illiterate had not just started school but completed grade 6. These children were being schooled but not educated. Schooling without learning is just time served. Unfortunately, Zambia is far from alone in having schooling without adequate education.

In India, for example, the government made a major commitment to finance elementary education. Central government spending on elementary education increased 11-fold between 2001 and 2013. Over the same period, assessments show the percentage of children in grade five who could read or do simple subtraction declined.

In Indonesia, a major commitment to increasing teachers’ salaries has led to more than $4bn in additional spending a year – but a rigorous evaluation shows almost exactly zero learning gain from students taught by the more highly paid teachers.

What is the TL;DR as to the cause?  Ain't all the one-laptops-per-children helps?
