DAR ES SALAAM, March 6 (Xinhua) -- Africa is facing a severe learning crisis that thwarts its economic growth and the well-being of the citizens, said a new World Bank study released in Tanzania on Monday.

The study, released in Tanzania's commercial capital, Dar es Salaam, said learning levels across the region are alarmingly low.

"The region has made considerable progress in boosting primary and lower secondary school enrollment, but some 50 million children remain out of school, and most of those who attend school are not acquiring the basic skills necessary for success later in life," said the study.

It said among second-grade students assessed on numeracy tests in several sub-Saharan African countries, three-quarters could not count beyond 80 and 40 percent could not do a one-digit addition problem.

"In reading, between 50 and 80 percent of children in second grade could not answer a single question based on a short passage they had read, and a large proportion could not read even a single word," said the study.

"Providing a high-quality basic education for children across the region is an economic necessity, as well as a moral imperative," said the World Bank's Senior Director for Education Jaime Saavedra.

"This report provides a sobering look at Africa's learning crisis and the region's potential to solve it," Saavedra said. "Young Africans can transform the region and create lasting economic change, but they need to be equipped with the skills and human capital to do so."

Specifically, the report urges countries to focus on student progression and the "traffic jam" in early grades, where children are stuck for many years with little learning, and are often taught in a language they don't fully understand.

According to the study, African governments spent an estimated 204 U.S. dollars per student for primary education in 2014, less than half of the amount spent in South Asia, the region with the next lowest level of spending.
