A related question: can anyone provide a link to what the K-12 syllabus of the former Eastern bloc actually was? Certainly USSR and Hungary must have had impressive curricula. I had a Croatian friend who said that his basic skills in algorithms (which were very advanced from my viewpoint) was based on his math schooling in the former Yugoslavia, which he said treated very advanced concepts early on. Is there any link to an English version of these syllabi?
