| In recent years,with the rapid development of Internet technology,many high-tech technologies have been introduced into education,which has promoted the continuous development of the education informationization process.Among them,the development of e-reading makes people's reading style no longer confined to paper-based reading,but also affects the transformation of education and teaching methods.Therefore,electronic textbooks came into being.At the same time,the decision-making psychology of userst' choice of products in the Internet information age has also undergone tremendous changes,from the initial functional consumption to the popular experiential consumption in recent years,which is particularly concerned in the field of electronic textbooks and has become an area of educational technology.The focus of attention of various scholars.It is not only limited to satisfying the intellectual needs,but also the electronic textbooks that pursue humanized design and immersive experience,which is more in line with the development concept of "people-oriented".This research starts with the literature research and analysis of electronic textbooks at home and abroad,focusing on the research of electronic textbook standards and the research on resource activities in electronic textbooks.It is found that the development of electronic textbooks in China is in a chaotic state.Most of the knowledge and application of electronic textbooks are mainly static content display.Most of the standard research of electronic textbooks is in theoretical research,lacking unifonn format standards,and there is no clear electronic textbook.Publishing model and architecture design research.Although the practical application of electronic textbooks in foreign countries is quite rich,there is still no clear research on the standardized records of learning activities in electronic textbooks.With the advent of the era of big data,how to provide learning services and learning support by tracking and recording learning activity data in electronic textbooks needs to receive sufficient attention and attention.Based on the research of relevant literature and materials related to electronic textbooks at home and abroad,this study uses xAPI technology to extend the epub3.0 e-textbook standard,and studies the records of learning activities and their sharing mechanisms in e-textbooks.Based on the extensibility analysis of epub3.0 standard,this paper designs the functional activities of rich media presentation,learning evaluation and feedback,and problem test in electronic textbooks,and proposes the extension scheme of epub3.0 standard based on xAPI technology.Then the technical implementation of the extension scheme is described,including the construction of the development environment,the creation of epub3.0 electronic textbook,the collection of learning activity data,the transmission and storage of data,and other detailed development processes.Finally,the implementation scheme is tested and analyzed.The results show that the extended electronic textbook realizes the standardization of format and learning activity data,and the content display method is more diverse and diverse,enabling real-time data storage and multi-user and multi-platform data sharing.This article focuses on the current application of electronic textbooks,based on the support of international mainstream standards,trying to build an intelligent,networked,personalized electronic textbook learning environment with good user experience and focus on exploring educational data.This study combines the epub standard with the xAPI standard,which is highly innovative and practical.The integration of the two standards will bring value-added effects,and at the same time provide an overall architectural design idea for the development and production of current electronic textbooks.Promote the promotion and digital learning of electronic textbooks,and provide strong technical support for high quality and efficient teaching and education data sharing. |
