摘要
该文创造性地在建筑材料实验中引入扫描电镜微观结构试验,并依据专业性及所需时间的不同,设置了基础型、验证型与探究型相结合的多层次微观结构试验模式,以满足拥有时间、兴趣、想法和能力不同的学生参与不同深度的微观结构试验。实践证明,多层次微观结构试验完善了建筑材料实验课程体系,提升了学生对课程的学习兴趣,进而增强了课程有效性;通过将微观结构与宏观性能相结合,促进了学生对建筑材料性能的全面理解,提高了学生的综合素质与科研能力;同时有利于大型科研仪器在本科教学中的运用,提升了大型仪器的使用效益与实验室管理水平。
This paper creatively introduces the microstructure experiments based on scanning electron microscopy(SEM) to the course of building materials experiments. According to the differences in the professionalism and time required, a multi-level microstructure experiment model, including the basic type, verification type and exploratory type, has been set up, which allows students with various time, interests, ideas and abilities to participate in the microstructure experiments in different depths. The practice shows that microstructure experiments have enriched the curriculum system and increased students’ interest, thus enhancing the effectiveness of the course. By combining the microstructure and macro-performance, the experiments can facilitate students’ overall understanding of building materials, improve their comprehensive quality and scientific research ability. Besides, the experiments are conducive to the application of large-scale scientific research instruments in undergraduate teaching, and improve the use efficiency of large-scale instruments and the level of laboratory management.
