Well. Not surprising to see they have found an easy solution to a way more complicated problem. "It's the color of the pens," they say, "just change that, and our teachers won't be forced to do a better job."
Of course that's stupid. There's a few other words for it, but stupid should do for now.
After all, the issue is much more complicated than this makes it seem. What needs to be done is establish a role of teachers as "partners" of students, working together to get the students through class with good marks and, especially, good skills. Teachers must be selected with great care and re-evaluated every few years to ensure that they still have the motivation to pass on to students. If they don't - well, how about a nice job in the school bureaucracy then?
I mean, let's not forget - this is the basic school level we are talking about. A phase in life where students still have the luxury of only having to listen and do their homework - as opposed to uni, where you have no one to kick you if you happen to be slacking off.
