In kindergarten dialect teaching, the combination of computer network and dialect teaching methods is helpful to improve kindergarten children's cognition of dialects, which can not only enrich teaching resources and teaching forms, create efficient and fast learning methods, but also cultivate students' autonomous learning ability and exploration and innovation ability, thus continuously improving teaching quality and level. First of all, the integration of computer network platform in kindergarten teaching is to better understand and master children's dialects; We need to design a teaching platform for children's dialects that can meet children's learning needs. Finally, this paper designs a computer network platform for dialect teaching in kindergartens, analyzes its functions, and tests its characteristics and performance. The experimental results show that ten testers rated the performance of the platform as 5.0. This shows that the computer network platform has good performance.
