摘　　要：工程图样是工程界的语言、技术课的奠基石,但因其内容抽象、知识点繁多及学生空间想象力差等原因,导致机械制图课程目标达成度不理想。将直观的知识图谱应用于抽象的机械制图课程,抽丝剥茧逐步形成了以“国家标准”为核心,延伸“形体结构递进”及“表达方法递进”两主线,旁分“尺寸标注”“技术要求”及“工程实例”三分支的教学模式。通过混合教学过程中的实践与探索,发现该模式能高效形成知识的系统性,便于达成知识目标、能力目标及素质目标。mechanical drawing course has gradually formed a teaching mode centered on“national standards”,extending the two main lines of“progressive form and structure”and“progressive expression methods”,with three branches of“dimension annotation”,“technical specifications”and“engineering examples”.Through practice and exploration in blended learning,it has been found that the model can effectively form a systematic knowledge structure,facilitate the achievement of knowledge goals,ability goals,and quality goals.
