Studies by World Bank and ADB  note  that countries leading the assessments in literacy and numeracy have a similar feature. Their textbooks are produced by private publishers, and school heads are  free to select the learning materials best suited for their students and their learning conditions. In many developing countries, whose textbooks are produced and supplied by the government, production problems and delays abound.  Latest educational research have shown that children retain information and think critically from reading a print book versus a digital screen. School administrators in countries like Denmark, Finland  have pushed for the return of printed books in their classrooms because of this.What innovations can private publishers do for learning materials in state or public schools?  What are the potential gains to be derived from this type of  partnership with government?
