As scientists devote themselves to science popularization, science popularization ability has gradually become an important factor affecting scientists’ motivation and effectiveness in science popularization. However, there are few related pieces of researches in China at present. Therefore, the interviewees in this paper are 26 scientists with science popularization experience, and the research focuses on their experience and opinions on science popularization ability improvement training. By comparing the similarities and differences with foreign-related research, it is finally concluded that science popularization training for scientists should focus on six dimensions: to promote scientists to realize the significance and challenges of science popularization from multiple dimensions, introduce scientists to general techniques for science popularization, encourage scientists to develop personalized science content, remind scientists to pay attention to public interest and feedback, encourage scientists to use social platforms for science popularization, emphasize to scientists the importance of collaboration. It also explains the relevant strategies available for each dimension.
