【摘要】 针对新工科与新农科背景下画法几何与机械制图课程知识碎片化、实践创新能力培养不足的问题，本文构建了基于知识图谱的赛教融合教学模式。该模式以“概念—技能—应用”逻辑构建课程知识图谱，实现知识可视化导航；以学科竞赛为驱动，激发学生创新能力，形成“知识导航+实践驱动”的双轮协同机制。实践证明，该模式显著提升了学生的工程实践能力与竞赛成绩，其核心优势在于，知识图谱支持动态教学调整机制能精准定位学习难点并靶强化，从而优化教学效果。本研究为机械制图课程的深化改革提供了有效的新范式。更多还原

【Abstract】 Under the background of emerging emgineering and agriculture disciplines,the Descriptive Geometry and Mechanical Drawing Course faces challenges of knowledge fragmentation and inadequate cultivation of practical innovation capabilities.To tackle theses issues,this study proposed a pedagogical model which integrated competition-based learning with knowledge graph technology.This model operated on a dual-pronged synergistic mechanism:first,a course knowledge graph was structured around a "Concept-Skill-Application" framework to enable visualized knowledge navigation;second,academic competitions were integrated as a primary driver to foster student creativity and innovative.Empirical evidence indicated that the proposed model markedly improved students creativity and innovation.Empirical evidence also indicated that the proposed model markedly improves students’ hands-on engineering abilities and their achievements in competitions.The key strength of this model is its dynamic pedagogical adjustment system,which utilizes the knowledge graphs accurately identify knowledge gaps and implement targeted instructional support,thus enhancing overall learning outcomes.The research offers a viable and novel paradigm for the systematic reform of mechanical drawing education.更多还原
