This is because the goal of preschool education is to arouse children's interest and curiosity in a simple and vivid way and help them understand and master basic knowledge and skills. Therefore, PPT courseware used in preschool education usually uses big pictures, simple words, animations and other elements to make children better understand and remember.

Of course, the specific PPT courseware design still depends on the teacher's requirements and teaching content. Some teachers may use more elements, such as graphics, audio or video, to enrich their children's learning experience. But in general, PPT courseware in preschool education should be concise, intuitive and easy to understand, so as to adapt to children's cognitive level and attention endurance.
