摘要
工程实践课程中众多实践模块需要学生自行设计及制作,基于工业制造中必要且广泛应用的结构优化步骤,将结构优化思维融入工程实践课程,学生在实物制作之前进行强度、跌落分析等基础的计算评估,通过计算结果了解结构的薄弱位置,并以学生为主体对结构优化改进。教学实施效果表明,不仅加强了实践内容的知识点高阶性,学生课堂参与度和内驱力也显著提升,同时实物制作的废品率及耗材成本显著下降,教学反馈中学生对该内容的必要性和重要性持积极肯定态度。课程提升了学生的工程思维、创造力和解决复杂工程结构问题的能力,且更利于考核评价的客观公平性。
In the engineering practice course,numerous practical modules require students to design and produce on their own.Based on the necessary and widely used structural optimization steps in industrial manufacturing,structural optimization thinking is integrated into the engineering practice course.Students conduct basic calculation evaluations such as strength and drop analysis before physical production,understand the weak points of the structure through calculation results,and take students as the main body to optimize and improve the structure.The teaching implementation effect shows that not only has it strengthened the higher-order knowledge points of practical content,but students'classroom participation and internal drive have also significantly increased.At the same time,the waste rate and consumables cost of physical production have significantly decreased.In the teaching feedback,students hold a positive and affirmative attitude towards the necessity and importance of this content.The course enhances students'engineering thinking,creativity,and ability to solve complex engineering structural problems,and is more conducive to the objective fairness of assessment and evaluation.
