But...

In the light of everything said in the previous post, there is a but...

I have always tried to engage my students and make learning less stressful. That is why I am known as a "kind" teacher. That doesn't mean I never give bad marks, I just avoid shouting and intimidating. But some students think that allows them to do whatever they want at the lessons, they think that positive attitude is the synonym of anarchy, and I have to show them the opposite. Maybe, it's the feature of our educational culture, where a strict, demanding and serious teacher is a good teacher. What can be done in this respect, I wonder?
