An international conference took place in Dakar, Senegal, to find new ways to get and keep girls in school.
    The United Nations Children’s Fund says nearly 72 million children were not in school in 2007. (26) More than half are girls, and more than two-thirds are in sub-Saharan Africa, South Asia and West Asia. School attendance has improved in many areas. But the head of UNICEF says: "Unless we all work harder,there may still be 56 million children out of school in 2015. "He says progress and economic development depend on educating girls as well as boys. Educated girls are also at lower risk of violence, abuse and diseases like AIDS.
    The UN Girls’ Education Initiative organized the meeting of 200 scholars, aid workers and government officials from 22 countries. The initiative was launched in Dakar ten years ago. The aim is to bring primary school education to all girls and boys worldwide by 2015.
    (27) The conference centered on three main problems to getting girls out of school: violence,poverty and poor quality education. Donors are pumping in a lot of resources and civil society groups are working on access to education. But the truth is,75 percent of the children fail.
    (28) The UN official says schools need to modernize and improve what they teach and how they teach . For example, she says schools should teach African children in their native languages, not simply in English or French. To stay in school, experts say children must consider their education useful—and so must their parents.
