"Integrated, Three-Tiered" Digital Empowerment in Teaching Reform and Practice of Engineering Drawing

The current Engineering Drawing course faces challenges such as traditional teaching methods failing to meet students' personalized learning needs and unsatisfactory teaching outcomes. To address these issues, this study introduces advanced digital teaching tools and methods to improve teaching quality and student learning outcomes. A blended teaching model was adopted, integrating virtual reality technology, online learning platforms, and intelligent assessment systems. An "integrated, three-tiered" "theory-practice" project was designed to verify its effectiveness. Results show that digital empowerment in teaching reform significantly increased students' interest and performance, and enhanced their spatial thinking and practical skills.
