The problem is capitalism.
Nowadays it's all about reputation, which school can produce the kids with the best grades will get all the plaudits and money that comes along with it. Ultimately schooling and education institutes are run like businesses.
You'd be hard-pressed to find a school which tells you we aren't focused on results, we don't care if our kids don't score straight As, the important thing is the learning.
Syllabus is taught in such a way that it requires minimal thinking on the student's part. The teacher does all the thinking for them and gives them notes on what to memorize, what to practice, and tell them the precise steps or the most perfect way to do a sum or answer a question. In a competitive education system, you can't afford to give time to your students for learning on their own ... no no no! Not when it can be spent perfecting them, transforming them into the perfect examination robot, who will regurgitate all the perfect answers and solutions during nationwide assessments.
Because that's how you can make your students get better grades, it's a formulaic and successful approach to take, and better grades = better funding, more popularity, more money for the staff ...
That's why education is going backwards.
