后疫情时代背景下，线上教学的需求不减反增，内容、形式与教学结构不断优化与发展，与此同时，人们对博物馆公共教育的线上资源需求呼声渐长，尤其体现在儿童群体上。线上公共教育活动的形式可拓宽博物馆公共教育的辐射范围，打破地域限制，惠及更多缺乏公共教育资源地区的人民群众。公共教育作为博物馆的社会职能之一，在新的社会背景下需要不断更新其实践内容与形式，服务于社会。相比欧美发达国家的博物馆完善的线上儿童公共教育活动体系，我国的各个博物馆的线上儿童公共教育活动仍处于有待开发阶段。 由于博物馆线上公共教育也属于线上教育的一种形式，同样会面临科技带来的多种可能性，让线上儿童公共教育活动设计的过程中更显复杂混乱，许多博物馆在设计与实践过程中也容易顾此失彼。故此需要进行综合探索思考，参考优秀的国内外博物馆案例，将问题与思路方法集合研究。由于笔者是美术类专业背景，在本次实践部分的重点在于画面绘制，挑选侧重以美术角度进行实践尝试。 线上的儿童公共教育活动设计需要结合多学科视角进行思考与研究，本文从技术应用、视觉设计、教育理论等多视角综合讨论为此次研究的创新点，通过查阅博物馆学、传播学相关文献资料、参考国外博物馆线上公共教育实践案例与经验，结合实践尝试，分析与思考如何结合我国的社会背景，设计博物馆线上儿童公共教育活动，为推进国内博物馆线上儿童公共教育活动的发展提供思路与方法。

In the post-epidemic era, the demand for online teaching is not decreasing but increasing. The content, form and teaching structure are constantly optimized and developed. At the same time, people are increasingly demanding online resources for museum public education, especially for children. Online public education activities can broaden the radiation range of museum public education, break the regional restrictions, and benefit more people in areas lacking public education resources. As one of the social functions of museums, public education needs to constantly update its practice content and form to serve the society under the new social background. Compared with the perfect online public education system of the museums in Europe and America, the online public education activities of the museums in our country are still in the development stage. As online public education in museums is also a form of online education, it will also face various possibilities brought by science and technology, which makes the design process of online public education activities for children more complicated and chaotic. Many museums are also prone to neglect one thing and lose the other in the design and practice process. Therefore, it is necessary to conduct comprehensive exploration and thinking, referring to excellent domestic and foreign museum cases, to study the problems and ideas. As the author has a major background in fine arts, the focus of this practice is on picture drawing, and the selection focuses on practical attempts from the perspective of fine arts. The design of online public education activities for children needs to be considered and studied from a multidisciplinary perspective. The innovation of this study is comprehensively discussed from multiple perspectives, such as technology application, visual design and educational theory. By referring to museology and communication literature, overseas online public education practice cases and experiences in museums, combined with practical attempts, this paper analyzes and considers how to design online children's public education activities by combining our social background, and provides ideas and methods to promote the development of online children's public education activities in domestic museums.
