Visual Research Of Knowledge Dissemination In Technology Short Video

While the development of science and technology continues to promote the progress of the national economy,it also brings a serious problem that is the mismatch between audience cognition and the spread of scientific knowledge.In 2018,Wu Zhiyong mentioned in the "China Education News" that people's understanding and understanding of scientific and technological information lags far behind the speed of technological development.But at the time,he attributed this problem directly to the lack of scientific and technological communication in the media.The author has found through multi-platform and multi-media investigations that even though the types of communication platforms are increasing in recent years and the channels of technology communication are constantly enriched,people still do not have enough knowledge and understanding of scientific and technological knowledge.For example,with the shortcomings of the two advantages of the network and smart phones,the number of users from 242 million in 2017 to 353 million in 2018 has attracted the participation of China Association for Science and Technology,Chinese Academy of Sciences,People's Network and other institutions to launch a large number of technology videos.In addition to thousands of PGC users,there are nearly 10,000 UGC users joining the ranks of technology communication.Such communication has never been able to get rid of the problem of“scientific communication and people's needs misplaced” that Wu Dan's teacher once proposed.Many researchers will These problems are attributed to the education level and cultural background of the audience,but the author analyzes the shortest video platform of the largest user in all media,and finds that the vast majority of scientific and technological content disseminated on the platform is concentrated and basically derailed from the current level of technological development.People still stagnate in the early stage of popularization of scientific knowledge,and the level of cognition has been hindered.In order to further explore the above issues,the author selected the most popular platforms for scientific and short video,and the most popular PGC identity authentication,and the most authoritative video platform of the short video platform of China's major science institutions,the main research platform,inspected August 18-18,2017 During the first year of August,the top five searchers,the highest number of fans,and the most clicked users were the content visualization of 504 short videos from Popular Science China,China Science Expo,and Science Popularization World.Whether the degree of visualization of scientific knowledge in short videos can meet the cognitive needs of the audience and refine related issues.At the same time,Zhu Shuchao's views on audience and information visualization were taken.A total of 32 interviewees were selected for preliminary interviews using the snowball sampling method.The interview outline was made based on the analysis of the two chapters of the form and content,and an attempt was made to explore the short video visualization of science and technology.The meaning of knowledge shaping is the same or similar to the meaning of the audience's perception.Different from the publication and dissemination of past science and technology journals,this paper focuses on the degree of coordination between technology communication and audience perception.Even in recent years,some scholars have paid attention to the visualization of video platforms,but most of them visit from the platform day and month.The amount waits,and few scholars examine the technology video itself.This study will start from the perspective of communication,combined with Ren Yue and Zhao Huichen's exploration of the expression and production process of image and visual meanings,and analyze the short-term video technology knowledge dissemination from science(content),form(media),meaning(The audience is carried out in three parts,and closely with the theories of symbols,language,narrative,images,rhetoric and related theoretical knowledge,trying to pry into the audience's cognition of scientific and technological knowledge in the science and technology communication,and focusing on the current mode of technology communication on the short video platform.Summarize the visual content and structure of scientific knowledge dissemination in short videos,and further analyze how scientific knowledge can be realized through visual means.
