The results speak for themselves.
The latest Trends in International Mathematics and Science Study (Timss) and the Programme for International Student Assessment (Pisa) have been released - and, once again, East Asian countries have ranked the highest in both tests.
Over recent years, other countries' positions have gone up and down in the tables, but East Asian education - which includes China, Singapore, Taiwan, South Korea and Japan - continues to dominate. And the gap between these countries and the rest of the world is getting wider.
The reasons why East Asian countries are way ahead of the pack as far as education is concerned have long been debated - but it essentially seems to come down to four factors.
1. CULTURE AND MINDSET
There is a high value placed on education and a belief that effort rather than innate ability is the key to success. East Asian researchers usually point to this as the most important factor for this region's high test results.
The positive aspect of this approach is that there is an expectation that the vast majority of pupils will succeed. Learners are not labelled and put into "ability" groups - as they are in England, where this is the norm even in many primary schools. So, in East Asian countries, everyone has the same access to the curriculum - which means many more pupils are able to get high grades.
Formal schooling is also supplemented by intensive after-school tuition - at the extreme, this can see children studying well into the night - and sometimes for up to three hours of extra school in the evening on top of two hours of homework a day.
But while this intensive after- school study can get results, it's important to recognise that in many East Asian countries, educators worry about the quality and influence these "crammers" have on the mental health and well-being of children. And many studies looking at pupils' experiences in these schools have reported high levels of adolescent stress and a sense of pressure to achieve - for both the students and their parents.
2. THE QUALITY OF TEACHERS
Teaching is a respected profession in East Asia, where there is stiff competition for jobs, good conditions of service, longer training periods and support for continuing and extensive professional development.
In Shanghai, teachers have much lower teaching workloads than in England - despite the bigger classes. And they use specialist primary mathematics teachers, who teach two 35-40 minute lessons a day. This gives the teachers time for planning - or the chance to give extra support to pupils who need it - along with time for professional development in teacher research groups.
In Japan, "lesson study" is embedded in primary schools. This involves teachers planning carefully designed lessons, observing each other's teaching and then drawing out the learning points from these observations. And lesson study also gives teachers time to research and professionally develop together.
3. USING THE EVIDENCE
Ironically, the theoretical basis for East Asian education has been heavily influenced by research and developments in the West. For example, Jerome Bruner's theory of stages of representation, which says that learners need hands-on experiences of a concept - then visual representations - as a basis for learning symbolic or linguistic formulations. This has been translated in Singapore as a focus on concrete, pictorial and abstract models in mathematical learning. For example, this might mean arranging counters in rows of five to learn the five times table, then using pictures of hands that each has five digits, before writing multiplication facts in words, and then adding in numerals and the multiplication and equals signs.
4. A COLLECTIVE PUSH
In the 1970s, Singapore's educational outcomes lagged behind the rest of the world - the transformation of Singaporean education was achieved through systemic change at a national level that encompassed curriculum development, national textbooks and pre-service and in-service teacher education.
Similarly, in Shanghai and South Korea educational change and improvement is planned and directed at a national level. This means that all schools use government approved curriculum materials, there is more consistency about entry qualifications to become a teacher and there is much less diversity of types of schools than in the UK.
The success of East Asian education has turned these countries into "reference societies" - ones by which policymakers in the United Kingdom and elsewhere measure their own education systems and seek to emulate. Interest in East Asian education in the UK has informed the current "mastery approach", which is used in primary mathematics. Teaching for mastery uses methods found in Shanghai and Singapore and has been the basis of many recent research projects - some sponsored by government funding and others promoted by educational charities or commercial organisations.
But of course, only time will tell if some of the success of these two education systems can be reproduced in the UK, while avoiding some of the negative experiences - such as stress and burnout - associated with the East Asian approach to education.
