Here are 5 points that stand out for me:

1. Focusing on PISA scores, or scores on any other test, is not the same as focusing on student learning in the classroom. Too often, a focus on standardized testing can actually have a harmful affect on teaching and learning.
2. Education is an investment -- not an expenditure. Cutting education is like a farmer who sells his top soil.
3. Teachers don't need surveillance -- they need support. You don't improve the education system by firing individual bad teachers -- you improve the education system by creating good teachers and then trust them to do their job.
4. Teach Less -- Learn More. Pasi Sahlberg writes about Finland and Gary Stager writes about the Maker Movement. Pak Tee Ng reminds us that, "more of the same teaching is not the way to inspire better learning." Efforts to "teacher-proof" education via standardization is not the solution, it's the problem. 
5. You say you want this, so why are you doing that? Unfortunately, myths are often more satisfying to us than the truth - in education we are satisfyingly distracted by a great many myths. If we are to improve school, we have to allow it to change. And if we want to make the right change, we need to be evidence and research based.
