工程案例式教学法在基础力学教学中的应用

The Application of Engineering Case Teaching Method in Basic Mechanics Teaching

摘要: 针对当前基础力学教学工作中存在的一些问题，提出了一种工程案例式的教学方法。该方法通过具体的5个教学步骤，即工程案例的讨论、提出问题、介绍并引入解决问题所需要的力学知识、解决问题、总结引申，使学生能够更加深刻地理解所学力学知识的专业用途以及用法。分析了该教学方法具有的两大优点，包括可以提高学生们学习基础力学的兴趣，更好地适应当前高校基础力学学时减少以及学生数理基础下降的现状。最后以牛头刨床的运动学特性研究为工程案例，演示了面向机械工程专业开设的《理论力学》课中点的速度合成公式的工程案例式教学的全过程。子体温度的原理和方法，并和常用的局域热平衡条件下的温度诊断进行了比较，得到了一些重要结论。本研究对空间等离子体温度诊断具有重要参考意义和价值。

Abstract: A teaching method called engineering case teaching method is proposed in this paper in order to solve some problems existing in the basic mechanics teaching. The method includes five specific teaching steps, namely engineering case discussions, posing questions, introducing the mechanical knowledge required to solve questions, problem solving, and summarizing. Students can more deeply understand the purpose and usage of mechanics knowledge according to the engineering case teaching method. Two advantages are analyzed which include improving the interest of the students on learning basic mechanics, and better adapting to the current situation of college about the reducing class hour of basic mechanics and students’ decreased mathematical foundation. Finally, taking the kinematics characteristics study of the shaper as an engineering case, the whole process of engineering case teaching for the velocity synthesis formula in the theoretical mechanics is demonstrated in this paper.
