“汽车诊断学”线上线下混合教学模式研究

李良敏 李猛 张凯超

摘要“汽车诊断学”课程主要讲述了汽车故障诊断中信号的测量技术、常用信号处理方法和状态识别方法，其特点是理论性强，概念原理较为抽象，课程知识点繁多，囿于课时限制，教师无法对所有知识点展开阐述，传统的课堂教学效果不够理想。为了全面提升“汽车诊断学”的教学效果，引入了线上线下混合教学模式，从开课前准备、课前预习、课堂活动设计、课后复习等四个方面探讨了“汽车诊断学”线上线下混合式教学课程建设的具体方法，并重新设计了“汽车诊断学”的课程考核方式。

AbstractThe course “Automobile Diagnostics”focuses on the signal measurement technology，signal processing methods and pattern recognition methods in automobile diagnosis，featured with strong theory，abstract content and large number of knowledge points. Due to the limitation of class hour，teachers can't explain all the knowledge points clearly. The traditional class teaching effect is not ideal. T The practice of the online and offline hybrid teaching mode in the course of"Automobile Diagnostics" was researched in this paper. The specific teaching reformation methods from four aspects：pre-school preparation，preview before class，classroom activity design，review after class were discussed in detail. Finally，the course assessment method was re-designed.

信息技術发展推动了教育教学模式的改革与创新，催生了许多新的教学模式，如MOOC、SPOC、线上线下混合式教学等。[1][2]其中线上线下混合式教学模式融合了传统课堂教学模式与在线教学模式的优势，受到了广泛关注。“汽车诊断学”作为汽车服务工程的专业发展课之一，具有理论性强，概念原理复杂抽象，课程知识点繁多等特点，采用传统的课堂教学模式效果欠佳。有必要通过引入线上线下混合教学模式进行课程改革创新，实现“汽车诊断学”课程内涵式发展。
