LTD.10.18063/EIR.v4i1.1312ArticleResearch on the Construction Paths of Digital Textbooks Empowered by Intelligent Technologies: A Case Study of Thermodynamics and Fluid Mechanicshttps://artdesignp.com/journal/EIR/4/1/10.18063/EIR.v4i1.1312LvYuexia,ChengShen,LiuXiaofan,YiMingdong,ZhangLili2026412026-01-26 To accelerate the digital transformation of higher education and the rapid advancement of intelligent technologies, the development of digital textbooks has emerged as a crucial pathway for enhancing the quality and effectiveness of engineering education. Taking the core mechanical engineering course Thermodynamics and Fluid Mechanics as a case study, the limitations of traditional paper-based textbooks are systematically analyzed in the present study. To address these challenges, a comprehensive construction framework is correspondingly proposed, which includes knowledge system reconstruction, multimodal visualization, integration of virtual simulations, personalized learning support based on learning analytics, embedding of engineering cases, and data-driven continuous optimization. The proposed approach will improve visualization, interactivity, and instructional effectiveness in mechanical engineering education, and offer a replicable reference for the digital transformation of textbooks in related engineering disciplines.Digital textbooks,Mechanical engineering education,Artificial Intelligent,Education digitalization
