This study explores the concept, process, and strategies of constructing digital textbooks based on the SPOC (Small Private Online Course) platform, using the Electrical and Electronic Technology Experiment course as a case study. The article first introduces the main features of the SPOC platform and its advantages in experimental teaching, and analyzes the current teaching challenges in this particular course. Then, the article elaborates on the concept of using the SPOC platform to build digital textbooks, emphasizing the integration of knowledge transmission and skill development. The design principles, including interactivity, personalized learning, and process evaluation, are highlighted. The study details the development process of digital textbooks, which includes needs analysis, content organization supported by knowledge graphs, multimedia resource integration, interactive design and the establishment of evaluation mechanisms. Finally, it discusses potential challenges in implementing digital textbooks, such as technical integration, resource allocation and the transformation of teachers' roles, and offers corresponding solutions and recommendations. This research provides valuable theoretical and practical guidance for the development of digital textbooks in experimental courses in higher education.
