OBE理念下焊接成形虚实结合实践教学研究OA

To meet the demands of the"New Engineering"initiative for cultivating top-tier engineering and technology talent,this study reformulates the traditional welding forming practice teaching model based on the Outcome-Based Education(OBE)philosophy.The new model is structured around an integrated framework of"student-centered learning,virtual-real integration,progressive teaching,and diversified assessment",incorporating multi-stage content including AR-based virtual welding,manual gas-shielded welding,and robotic welding.A progressive learning path is established,guiding students from cognitive acquisition to skill development.In response to the limited professional foundation of lower-year students,the course adopts differentiated instructional strategies and utilizes virtual-real fusion technologies to enhance students' operational confidence and quality awareness.A diversified evaluation system is also introduced to strengthen formative assessment and reflective feedback,enabling continuous optimization of instructional approaches.Teaching outcomes indicate that the new model significantly improves students' welding posture,procedural accuracy,and ability to assess weld quality,demonstrating strong teaching effectiveness and scalability.This model provides a valuable reference for the reform and innovation of practice teaching in higher engineering education.
