研讨式教学量化研究方法初探——以“计算机辅助设计与制造”课程为例

计算机辅助设计与制造,简称CAD/CAM,狭义上是一项使用计算机进行零部件设计及机械加工的实用技术。作为一门专业课程,CAD/CAM课程也是机械电子及相关专业本科生的必修课和需要掌握的核心专业技能。文章基于CAD/CAM课程的教学实践,尝试在课程设计、实施等方面引入研讨式教学方法,并探索使用微信群、课程主页等新型信息交互工具进行师生互动,激发学生兴趣,拓展学习空间,使疑难问题得到实时解答。文章首次通过统计手段,较为详细地记录了师生互动的发言时间、关键词、互动频率,并进行了量化分析,尝试探索研讨式教学中师生的互动规律以提高沟通和学习效率。同时,针对采用研讨式教学的优势和存在的问题,文章也进行了讨论,以期对后续包括CAD/CAM课程在内的机械电子类课程开展研讨式教学提供借鉴和参考。

Computer-aided design and manufacture, CAD/CAM, is the technology for the design and manufacture of mechanical parts by using the computers. As a core course, this course has been widely delivered to the student in mechanical engineering and related majors. This research is based on the practices during the teaching process in CAD/CAM course, which is trying to integrate the discussion-based teaching method in the course design and deliver process. With the help of course website and WeChat group, the students are significantly motivated, and the learning efficiency is also obviously enhanced. For the first time, the time, content, and frequently of the interaction between teacher and students are quantified for the in-depth understanding of the discussion-based teaching process. The discussion for the advantages and disadvantages of using the discussion-based teaching in CAD/CAM is also provided in this research.
