【摘要】 新工科建设是应对新经济挑战、推动传统工科专业深化改革的重要举措，旨在培养实践能力强、创新意识突出的复合型人才。为适应这一要求，机械类专业亟须对核心课程进行深度改革。以“机械设计”课程中的《螺纹连接预紧和防松》教学单元为例，基于BOPPPS教学模式，展开教学改革。教学过程中以学生为中心，以学习目标达成为导向，通过工程案例导入激发学生的学习兴趣，结合预评估与后评估动态监测学生的知识掌握情况，采用翻转课堂提升学生的参与度与主动性。实践结果表明，相较于传统教学方式，该模式显著提高了课程教学质量和学生综合素养，为机械类专业的课程改革提供了有益参考。更多还原

【Abstract】 The construction of emerging engineering education is a crucial initiative to address the challenges of the new economy and promote the in-depth reform of traditional engineering programs, aiming to cultivate versatile talents with strong practical abilities and outstanding innovative awareness. To meet this demand, mechanical engineering disciplines urgently need to deeply reform their core courses. This paper takes the teaching unit of “pre-tightening and anti-loosening in threaded connections” in the Mechanical Design course as an example and implements teaching reform based on the BOPPPS teaching model. The teaching process is student-centered and goal-oriented, using engineering case studies to stimulate learning interest, combining pre-assessment and post-assessment to dynamically monitor knowledge acquisition, and employing flipped classrooms to enhance student engagement and initiative. The results show that, compared to traditional teaching methods, this model significantly improves teaching quality and students’ comprehensive competencies, providing valuable insights for curriculum reform in mechanical engineering disciplines.更多还原
