摘要
《计算流体力学》及《数值传热学》系列课程知识体系复杂、概念抽象且分散、易混淆概念较多;若教学方法不当,学生学完课程内容后往往对一些重要的概念似懂非懂,对概念相互之间的区别与联系亦是云里雾里,甚至对一些重要概念理解错误,导致面对数值仿真关键难题时不得要领。立足于此系列课程的特点,本文提出了一种综合辨析教学方法:通过典型案例引出概念,化抽象为具体,通过对照式、综合式、追根溯源式等辨析方法对概念进行综合辨析教学。该方法有助于学生辨析易混淆知识点,明晰零散概念间的区别与内在联系,从而实现对知识点的融会贯通和灵活运用,起到了拨云见日、升华理解的作用。文中以误差、稳定性和收敛性三方面相关易混淆概念的教学为例,介绍了该综合辨析教学方法的实施要点。该教学方法可为《计算流体力学》和《数值传热学》系列课程的教学或自学提供参考。
concepts concrete,and conducts discrimination teaching of concepts through comparative,comprehensive,and tracing techniques.This teaching method helps students discriminate those easily-confused knowledge points,clarify the differences and interconnections between scattered concepts,thereby achieving a comprehensive and flexible use of knowledge points,leading to an outcome just like“setting the clouds to see the sun and sublimating understanding”.With the examples of some important concepts,such as error,stability and convergence,this article introduced the implementation of the proposed teaching method.This teaching method is expected to provide reference for the teaching or self-study of CFD and NHT course series.
