No, it is not my standart for education institutions. And (I hope) it is not a standard to teach. Alas, it is standard thing for people to learn. And, sadly enough, thi applies in all the areas. Concepts are hard, let's go shopping. I see it all the time in somewhat techincal hobbies: not many care about what's happening at the concept level, they just want a button to push and get the result. If that button is moved, there is a trouble.
