《环境工程CAD设计》是环境工程专业的重要课程,操作性强,其最终学习成果是以图形作品的形式呈现,其中有二维作品,也有三维作品。同时,学生还需要对各图形作品在环境工程中的工艺原理、设备使用方法及立体构造等有清晰的把握。这在传统的“讲中教,听中学”教学中是很难实现的。传统的教师“一言堂”禁锢了学生的思维,弱化了对学生的技能培养,扼杀了学生 “Environmental Engineering CAD Design” is an important course of environmental engineering, strong operability, the final result of the study is presented in the form of graphic works, including two-dimensional works, there are three-dimensional works. At the same time, students also need to have a clear grasp of the process principles, equipment usage and three-dimensional structure of each graphic work in environmental engineering. This is difficult to achieve in traditional teaching of “teaching in middle school and listening to middle school”. Traditional teachers “a word of the Church ” imprisoned students’ thinking, weakening the skills training for students, killing students
