Lego's educational philosophy is to learn while doing, and learn while playing. It is to let children improve their interest in learning, enhance their practical ability and cultivate various skills in the process of their favorite activities. Classes are organized in small classes, and more are group discussions. In Lego class, children are unconstrained and active learners, while the teacher is just a guide and consultant, discussing or interacting with children and mobilizing their learning enthusiasm. Lego learning courses involve not only simple knowledge of geometry and physics, but also the cultivation of various abilities. In class, teachers will set certain tasks for children and construct corresponding works through their own imagination and understanding. They don't tell children a knowledge point or principle directly, but learn the principle and application in the process of building practical items commonly used in life. Without a complete set of pictures and cards, children must use their own hands and brains and think for themselves if they want to complete the task of this lesson. After-class lectures and small works will improve their communication skills, such as thinking, organization and logic. Nowadays, children are relatively lack of training in this field. Lego is not just a simple hands-on class or a simple expression class, but a comprehensive class.
