The advantage is legible writing and time saving, the disadvantage is the passivity of students. There is no complete silence in the classroom, communication is possible in almost every desk. Mostly, however, about solved examples. I am pleasantly surprised that the students take the help of each other as an automatic procedure, they give advice and explain. The teacher tolerates a certain level of noise, but twice during the lesson she asked the students to calm down. In one example, students found "nothing to complain about."
