Pupils in the poorest countries are suffering from a lack of basic textbooks, according to a report from a United Nations agency. The study from UNESCO gives examples such as reading books in Cameroon being shared between 12 students. The report is calling for a more centralised buying system which would make them more affordable. Report director Aaron Benavot says textbooks are an important way of raising standards in school. "Next to a good teacher, well-designed textbooks in sufficient quantities are the most effective way to improve students’ learning."
   The report suggests the process of distributing textbooks should be approached in the same systematic way as public health programmes. "a new system must be set up so that textbooks can move cheaply and effectively from a printing house to school and into the hands of children." says Mr Benavot.
