Independent work is fine, but it must be sufficiently explained, so if students take away from the general circulation of the atmosphere that the heat is up and cold down (and they are able to tell me that there is more heat in the mountains than in the lowlands), because Mr. the teacher said that the down arrows should be colored blue and the ones going up should be red, so something is wrong. But when I teach, I have freedom there. I can do whatever I want. My hands are free. I can try what teaching style I consider suitable.
