Oh my god...
If you have kids at home...and you tell them to clean their freaking room...do you make it a "fun game" for them? Do you tell them that each article of clothing is a piece of of a magic potion, do you tell them that each plate and cup they bring down to the kitchen is really a magical golden nugget?
When you make your kid mow the lawn...do you first convince them that each blade of grass is really en evil being from Lord of the Rings and that they are destroying the bad guys?
Parents says it...kid does it
Teacher says it...student does it
Coach says it...player does it
Its not "kids these days" it never has been, it never will be. It is "parents these days" and it always has been and it always will be. When I was in school, not that long ago, and I went home and told my mom or dad "Uggg, its boring, that class is boring" they said "So what, learn it, get a decent grade and move on, not everything in life is going to be super exciting, its your job to do well in class"
So because school has always been boring, we can't try to do anything to make it more enjoyable. The things you remember most from school are things that you were interested and engaged in. You can do enough to pass a test, but how long does that information stick with you if you aren't engaged? How much do you still remember from your high school classes? The stuff I still remember are things I found interesting or were presented in an interesting way. I got As and Bs in school, but I couldn't pass many of those tests if I took them again today. Why not try to make things more interesting so they can do more than just pass a test?
I have 18 month old twins, so I can't ask them to do much, but we have gotten them to do some things by turning them into games. They pick up their own toys, put their shoes away, put their clothes in the hamper, and throw their own trash away by making them fun. We have started to notice that they sometimes start picking up their things before bedtime without having to tell them. There are times they don't want to do it, but they do face some kind of puinishment if they don't do what we tell them. So what's wrong with telling them that something is a "magical golden nugget" if it gets them to do it? The difficult thing is finding what that golden nugget is as kids get older. They become less interested in the basic games you tried to play with them when they were younger. I think it's pretty lazy on the teacher's part to do it their own way and expect students to pick up on it.
