I feel normal education however is a little bit of both an explosion and problem-solving adventure. For example, in my nursery school see were exposed to letters and exposed to their sounds, there is no replacement for that initial phase. Also, we had to be exposed to the concept of problem-solving. Our teachers explained that if you put the sounds together you would get words. Then we were thought to read and understand simple comprehensions. They by themselves are expository in that the words contained in them were expected to be known or at least pronounceable by us. Then we solved the problem of putting the words together to answer simple questions on comprehension.

Problem-solving is very important but if a teacher doesn't take you by the hand to show you how a problem is supposed to look like you'll end up either not knowing ever what a problem looks like or finding out too late when others with good mentors would have directed them to what the problem is.

They say if have a destination you want to get to and you have a mentor you are already there.

the modern mind has to be built fast enough to keep up with advancements in society. So that more time is invested in building new things on the foundation laid by our ancestors.

So yes...I AGREE WITH YOU. But exposition is also very vital.
