摘　　要：为提升材料力学性能实验教学质量、广度和深度,在教学模式中融入角色赋值因素,通过角色认知引导,使学生对自身角色实践产生反思、体验。以金属拉伸实验为试点项目,考虑试件材料、试件状态和实验速率3种变量,设置实验关联组,通过小组和个人角色赋值,开展多线程对比实验。通过课前、课堂、课后3个环节的把控,将角色赋值贯穿教学改革全过程。结果发现,关联组数据存在异同点且具有一定规律,关联组内可总结出不同实验结论;改革后学生更注重个人价值表现,实验课堂效果提升明显,实验报告体现独立思考和个人特色;教学评价体系更加具体完备,各评价模块培养目标达成度均大于0.78,平均目标达成度为0.828。In order to improve the quality,breadth and depth of the experimental teaching in mechanical properties of materials and give full play to students'classroom initiative,role assignment factors are integrated into the teaching mode,which guides students to reflect on and experience their own role practice through role cognition.Taking the metal tensile experiment as the pilot project,three variables of specimen material,specimen state and experimental rate are considered to set up the experimental correlation groups,and multi-threaded comparative experiments are realized by assigning values to group and individual roles.Role implementation is carried out through the whole process of teaching reform by controlling three parts of the process:before class,classroom and after class.The experimental result finds that the data of correlation groups have similarities and differences and have certain patterns,different experimental conclusions can be summarized within correlation groups.Classroom practice finds that after the reform,students pay more attention to the performance of personal value,the experimental classroom effect improves obviously,the experimental report reflects independent thinking and personal characteristics,the teaching evaluation system is more specific and complete,the degree of achievement of cultivation objectives of each evaluation module is greater than 0.78,and the average degree of achievement of the objectives is 0.828.
