| Summary: | In view of the dual pressure of examination oriented and extra-curricular counseling in primary education, this paper discusses the relationship between knowledge acquisition and perceptual experience through the design of teaching aids according to the educational concept of reductive active learning method. Based on life style as logic, the interesting transmission mode is established, and the mechanical knowledge related to force and transmission is transformed into teaching aids that conform to the cognitive law of children aged 6-12. Children get sensory experience through practical operation. Therefore, it enriches the content of science course in primary school, and establishes the perceptual experience foundation for the later learning of mathematics, machinery and physics.
