离心泵的工作原理是《泵与风机》课程教学重点也是难点。作者在离心泵工作原理的授课环节中应用到了:列举生活实例、实验制作水泵简易模型、辅助动画视频、结合专业基础课《工程流体力学》中重要知识点、人文知识引入专业课程教学等多元化教学手段,针对高职院校学生学习学习起点低、基础薄弱、学习情况参差不齐、难以持续将注意力专注于课堂、理解消化理论知识有一定难度的特点收到非常好的教学效果。
Centrifugal pump principle of work is “pump and fan” course teaching is also difficult. The author applied the teaching principle of centrifugal pump to enactment of teaching examples: enumerating examples of life, experimenting with simple model of pump, assisting with animation video, integrating important knowledge in engineering basic mechanics, introducing humanistic knowledge into specialized courses, teaching diversification Means for students in vocational colleges to learn from a low starting point, the foundation is weak, the learning situation is uneven, it is difficult to continue to focus on the classroom to understand the digestive theory knowledge has a certain degree of difficulty received very good teaching results.
