基于线上线下混合模式的机械制图教学设计——以圆弧连接为例

Teaching Design of Mechanical Drawing Based on Online and Offline Mixed Mode

机械制图课程知识点多、学习难度大、内容枯燥,在传统教学模式下难以提高学生学习兴趣,在翻转课堂等现代教学模式下则要求学生占用大量课下时间进行自学,给学生造成较大学习压力;线上教学缺乏监督,难以保障学习效果。针对学生的学习和心理特点,在结合线上自学和线下课堂教学的基础上,借助网络教学平台发布教学资源,适量安排线上自学内容,线下课堂中合理进行教学设计,解决教学重难点内容。综合采用线上自主学习法、传统课堂讲解、任务驱动法、讨论式教学法等,以期提高学生线下学习质量、课堂专注度,促进知识内化,达到更好的教学效果。

Mechanical drawing course has many knowledge points and boring content,and it is difficult to learn.It is difficult to improve learner interest in the traditional teaching mode.In the modern teaching mode such as the flipped classroom,learners have to spend a lot of time on self-study after class.That results in great learning pressure on students.In addition,online teaching lacks supervision,which is difficult to ensure the learning effect.Combined with the learning and psychological characteristics of learner,online self-study contents were arranged appropriately through the online teaching platform,while the important and difficult contents were expounded in the school room.The following teaching methods were comprehensively adopt,such as online autonomous learning method,traditional classroom explanation,task driven method,discussion teaching method.The purposes are to improve learning quality and promote the internalization of knowledge,so as to achieve better teaching effect.
