The term 'CLASSROOM Sphere' can be broken down into two words, 'CLASSROOM' and 'GLOBE'. The word 'CLASSROOM' refers to a room in which classes are taught, while the word 'GLOBE' is a three-dimensional representation of the Earth. Together, these two words form the phrase 'CLASSROOM Sphere', which is used to describe the environment in which students learn. This environment is typically characterized by a physical space, such as a CLASSROOM, and a virtual space, such as the internet. In this way, the CLASSROOM Sphere provides students with a comprehensive learning experience that combines both physical and virtual elements.
