It is an endemic problem
As someone involved in and these days frequently frustrated by education, I'd just like to say that this article is spot on in highlighting a real contemporary deficiency in that area. And as the article also points out, it affects all fields of human activity. It used to be about teaching students how to think through and solve problems. Now, constrained by time and targets it more often than not simply gives convenient short cuts to finding the answers. How to pass an exam or test is what is taught, not skills.
