As someone with young kids can we get some specifics about this teaching?
I am an engineer by trade so its just how my mind thinks. I was once someone who just listened to the teacher, copy what she said was right, did the questions, then got a good grade. Once things became complicated and nuances stated to be part of the questions, this became a struggle of frustration. Once I figured out how to study, esp in math/science and much less in something like anatomy, math and science became extremely easy. Easy to the point where I ended up being a top 2 Engineering student in my whole college at a well known large engineering school.
I teach this to my kids early on and they hate me when I force them study this way. They get frustrated for a few weeks and then everything becomes easy. They then start to be the teachers to their friends. Either they get frustrated early or get frustrated 100x later.
Teachers teach how to do something. The HOW is easy, very easy. The why is hard. Once I learned the why, the how came with it.
As an example. We know 3/4 divided by 1/2 is the same as 3/4 x 2. That is the how but few know why this is allowed. It is allowed and makes sense because dividing by 1/2 is the same as multiplying the same equation by 2/2. The bottom cancels out leaving 3/4x2.
I can go on and on but I always teach why. I don't care if they get the answer right, I care that they think through why their solution is allowed.
I remember when I was in HS, and they taught the Pythagorean theorem. I spent a whole day proving that it works, and I learned more doing that than anyone could imagine.
Another point is calculus. People understand how to do differential equation and integration but very few know why you need to do it. Or what they are solving for. Differential equation gives the velocity at any point on a curve which helps physics problems. Integration is the volume under a curve with set limits which helps to solve physics problems. NO teacher really teaches this. They teach how, not the why.
Teach the why and they will remember it forever and love math/science. Teach the how and they will forget it in a year with a hate for math. To this day, even though I have not touched calculus or physics in 30 years can still solve most problems.
I took Org Chem I as a prereq for med school, got a high A. Got into med school so just needed to pass Org Chem II before med school. Never step foot in class but for exams. Took the Org Chem II exams with Org Chem I knowledge. Got a high B as most Org II questions can be deduced with strong Org I knowledge. Same goes for all math/science. Spend time to build an extremely strong base and will save you countless hours later on.
