Popular science short videos are usually vivid, intuitive and interesting. Compared with traditional media, short videos are more popular among the audience, as they are more in line with the market preferences and the preference of fragmented information of the Internet era, which has led to a change of methods in science popularization and an influx of content creators. Meanwhile, many problems have also arisen. For example, the number of creators is huge, but their content quality is uneven, and the low threshold of this field leads to a motley mixture of creators; many video creators emphasize on knowledge over value, resulting in the growing spread of rumors and pseudoscience amongst the rapid increase of video quantity; the platforms' algorithm fuels the production of "information cocoons", leading creators to create for web traffics and clicks; the lack of proper mechanism of evaluation as a guidance cause a scarcity of quality videos produced by scientists and technicians. Therefore, based on the current development of popular science short videos, the existing advantages, and emerging problems, this article proposes suggestions for the future development of popular science popularization short videos from the perspectives of the creation source, the evaluation mechanism of video quality and effect, and the integration of theory and practice in content creation.
