Education is multiplicative

When a high school student or university student comes to study with a teacher, he often unknowingly expects the teacher to teach the subject without much effort on the part of the student. In an ideal world, the student would have been given a magic pill with the words "Matan", he washed it with vodka, and boldly went to the exam. In the real world, you can do almost the same - only without a pill and with a different exam result.


Sensible students do not hope for a magic pill and even understand that the main thing is not to pass an exam, but to understand a subject that may come in handy in later life. To do this, they are looking for a good teacher and begin to understand the subject themselves, as a result of the level of knowledge and skills they overtake their passive comrades by an order of magnitude. Just like in the situation with the developers: a good developer can be 100 or more times more productive than a bad one, and a very bad project participant will do a little more harm.

Why is this happening? Assume that:
“Knowledge gained = knowledge that the teacher gave * knowledge that the student studied himself”
This simple formula shows that if at least one of the teacher-student pairs does not work, then the learning efficiency will be drastically reduced.

What can be advised for effective training (everything is simple and far from new):
  • Find a good teacher. How to do it: talk with a senior student; ask him for a list of literature worth reading before his course; quietly go to his lecture (even if you figure out something, you will have time to hear something).
  • Find good literature. To do this, just find one good book, and then "all good books refer to each other."
  • To study, because “education is multiplicative” and no matter how good a teacher is, if you multiply it by zero, then zero will result.

Purpose of this post
