Read this report from Marc Tucker: Standing on the Shoulders of Giants
This paper is the answer to a question: What would the education policies and practices of the United States be if they were based on the policies and practices of the countries that now lead the world in student performance? It is adapted from the last two chapters of a book to be published in September 2011 by Harvard Education Press. Other chapters in that book describe the specific strategies pursued by Canada (focusing on Ontario), China (focusing on Shanghai), Finland, Japan and Singapore, all of which are far ahead of the United States. The research on these countries was performed by a team assembled by the National Center on Education and the Economy, at the request of the OECD.
