What does Suhomlinski mean by making every wall talk?

It is to create an educational atmosphere for children, make full use of the campus, post slogans, inspirational words and learn words.

Suhomlinski once said: "No matter whether we plant flowers and trees, hang picture slogans or use wall newspapers, we will carry out in-depth planning from the height of aesthetics in order to tap its subtle educational function, and eventually even the school walls will speak." Classroom is an important stage for students to study, live and cultivate their ideological and moral character and behavior habits, a position for teachers to teach and educate people, and a place for emotional exchange between teachers and students. A clean, bright, warm and elegant classroom environment can inspire temperament, cultivate sentiment and inspire people.
