摘　　要：本文介绍了内压薄壁容器球形封头的应力测试实验课,详细分析了实验报告的相关数据,对学生的数据结果进行了详细的总结与讨论,并根据该实验的教学目标与实验报告,进行了课程设计与内容方面的客观评价。然后,结合学生的主观反馈意见,对原有教学方法进行一定修改,提高学生采集实验数据的有效性,建立数据采集的正反馈。初步探讨了该实验课程的改进方向形成了更清晰、易于评测兼顾价值、能力、知识三维发展的实验教学体系,实现以学生为中心的实验课堂模式。Here we described experimental classes for the stress distribution of the thin film vessel with spherical head and discussed the obtained stress values from the reports.Based on teaching goals and reports,course design and contents have been scientifically evaluated.Then,combined with students’comments,some changes and thinking have been made to improve the teaching method to assure the accuracy of the experimental data.Such a positive response would be helpful to improve the class quality.We have discussed the direction for class improvements,which would be feasible to balance the value,ability and knowledge in the teaching system.It could work as an example class for students being centered.
