Ushinski put forward many teaching principles, which can be roughly summarized as four: intuition principle, consciousness and enthusiasm principle, coherence principle and consolidation principle. Ushinski's teaching principles are basically formed on the basis of summing up previous educational experience, but the analysis and discussion of specific principles are based on new scientific achievements, making them more perfect and scientific. For example, the principle of intuition, ushinski from the psychological characteristics of children to discuss. He believes that children rely on shape, color, sound and feeling to think, and children's nature obviously needs intuition. Therefore, intuitive teaching is not based on abstract concepts and words, but on the concrete images directly perceived by children. Ushinski further discussed the position of intuition principle in teaching. He pointed out that the principle of intuition is one of many teaching conditions to ensure students to acquire solid and sufficient knowledge under the guidance of teachers, and the use of objects and teaching AIDS must be determined according to the characteristics of the subject and the age of the students. Teachers should not be too obsessed with intuition, but must pay attention to making the teaching transition from concrete to abstract, and finally cultivate students' thinking ability. In this way, he enriched and developed the intuitive principle put forward by educators such as Comenius and Pestalozzi.
