Sommario/riassunto |
|
Focusing on the future development of basic education in China, and on overcoming related issues, this book identifies key breakthroughs, priorities and important fields of basic education reform. In addition, it introduces the “Three Power Model” – decision-making, principals’ leadership, and learning power – to help address the challenges of future development. Unlike much of the research on basic education reform, the book draws on a forward-thinking, realistic and comprehensive project: bringing together 15 universities and research institutes, 16 provincial administration departments, and 100 selected primary and secondary schools, it has also been strongly endorsed by the nation’s leaders. After five years of practice and innovation, it has made significant breakthroughs in many provinces. Sharing unique insights into the project and its outcomes, the book offers an invaluable asset for education researchers, primary and secondary school teachers, and anyone interested in the evolution of basic education in China. |
