The difference between a top 3 place in the PISA analysis and the UK's position is barely statistically significant.
If you send all the low achieving children home on the day of the PISA test, then yep.....you're going to do better (friend who teaches in Shanghai and whose school features in the most recent PISA stats).
Teachers are respected in S. E. Asia.......here we have that good old saying: "if you can't do it, teach it....." In Scotland, it takes 6 years to train as a teacher: 4 years for first degree; 1 year for pdge and I year probationary teaching.............Kids are not stupid: they learn in an environment created by adults and if their parents do not respect teachers, then why should they?
English is a complex and challenging language which takes years to fully master.....Finnish is not.
If the English / Scottish education system was so bad..........why do so many International Schools choose it over the IB, or any other system?
Culture.........Scandinavia and S. E. Asia are more cohesive societies with a greater shared sense of community and values.
In the UK, education is intensely politicised. In Scandinavia and S. E. Asia, teachers are treated as experts and professionals. This results is far greater stability in the curriculum (and respect).
As the much travelled Finnish minister for education recently said....."You cannot transplant the Finnish model into the UK. Finnish society, culture and values are just too different". We need to look at the failings of our society, rather than the competency of our teachers, or the rigour of our curriculum.
