摘要 本教学研究旨在有效缓解目前宝石实践教学过程中师生比例失衡的矛盾,解决教学难点,提高教学质量。研究参考钻石内含物的标示方法,设计了典型宝石内含物标准符号;选取适当样品进行内含物的标准化图示并制作成"宝石内含物标准图例卡",在相关课程教学中进行试用。研究结果表明,"宝石内含物标准图例卡"能够较清楚展现宝石中内含物的类型以及相对位置和相对大小,对于解决各种宝石内含物教学过程中的难点有明显帮助,对学生学习效率有明显提高,在宝石实践教学环节推广应用前景较好。 This research is focused on how to effectively alleviate the currently unbalanced teacher-student ratio during the process of gemmological practice teaching, solve some prob- lems in teaching, and eventually improve quality of teaching. In this paper, the authors designed the standard symbol of typical inclusions with the help of standardized marking meth ods about gem inclusions, selected appropriate samples and draw inclusion diagrams, pro duced "gem inclusions sample card", and used those sample cards in the teaching practice. Questinnaires from students show the "gem inclusions sample card" can clearly demonstrate types, relative position and size of gem inclusions. It's obviously useful in solution of vari ous difficulties in practice teaching of gem inclusions, and it is also helpful for the improve- ment of students study efficiency and autonomous learning ability. Therefore, the gem in- clusions sample card" has broad application prospect in gemmological practice teaching.
