To research the status of scientific activity case resource construction in preschool, 19 publications were selected based on the screening criteria. The literature analysis method is used to develop research tools. The study finds that the case resource development groups are diverse and dominated by researchers, and the target audience is mainly in-service preschool teachers. The design of the activity elements reflected in the case structure is expected to be further optimized, specifically as follows: the response and direction of the activity cases to the science education concept are not sufficient; the theme of the event has a wide range of sources but more casual; the activity process highlights children’s observation and cognition, but the inquiry is slightly insufficient; the role of teachers as activity promoters and demonstrators is prominent, but the care of children’s subjectivity is inadequate; the evaluation link is generally missing and poorly designed. In order to promote the construction of preschool scientific activity case resources, this study believes that it needs to explore the path of in-depth cooperation of writing groups combining the needs of the audience, absorbing advanced scientific education research results and experience.
