Guided by distributed cognitive theory, this paper comprehensively analyzes the influential elements of content, tools, and contextual interaction in the online learning process through surveys and cases, explores online education platform design strategies from the distributed cognitive perspective, and provides experience design for online education platforms guide.Firstly, the characteristics and advantages of distributed cognitive theory involved in the experience design of online education platforms are explored through literature research, and user research is conducted by using questionnaires and interview methods to clarify the influencing elements of online learning under the perspective of distributed cognition. Secondly, a case study of the Coursera platform is conducted to analyze the elements distributed into their respective contexts; finally, the online education platform experience design strategy under the distributed cognitive perspective is refined. The proposed design methods such as visual knowledge mapping of design strategies, collaborative tools to promote deep interaction, and social behaviors to establish reciprocal sharing, can meet the learning needs of online learning users and solve their problems of low learning autonomy and low communication and collaboration efficiency.
