1) Children use sensory vision and hearing at the same time in class. If children's vision and hearing are strong (attention, resolution and tracking), they will fully hear and understand what the teacher said and the key knowledge prompted on the blackboard, so they will not be easily distracted and have high learning efficiency. Students with strong learning ability must have strong sensory attention, resolution and tracking ability, and their academic performance will naturally be high.
2) Therefore, only the synchronous training of sensory vision and hearing can make the efficiency of attending classes reach the best state, and the training will have obvious effects. Single visual training or single auditory training is not very effective. This is the experience gained by experts in learning ability education after years of research and practice.
3) The teaching materials are convenient, easy to operate, scientific and easy to train, and there is no learning pressure.
