A Reflectionon the Teaching Model of ‘Efficiency First’ under the ‘Efficiency First’Teaching Model Explore a campus that can ‘waste time’. By condensing the teaching space,we have freed up a ‘floating forest’ in the direction where the teaching building faces the morning sun, a space that does not resemble an image of a school.Students can quickly arrive to this forest after class.We also try to make some classrooms not to follow the strict norms,by‘hanging’them in each corner of the forest in free form,so that the classrooms are no longer considered as neatly arranged‘machines’.
