学生创新能力的培养已成为中国高等教育的重要导向,加强综合设计性实验的应用是提高大学生创新能力的有效途径。文章以水稻Ds插入突变体为实验材料,以突变体表型观测作为实验切入点,以遗传分析和Ds转座检测为实验学习重点,重新设计了一个分子遗传学综合性实验项目。在此基础上,通过知识拓展环节引导学生利用开放实验平台学习TAIL-PCR技术,进一步进入研究性实验。通过综合性实验到研究性实验的递进式教学体系,能够使学生深入理解表型与基因的内在联系、跳跃基因的概念以及转座子在基因功能研究中的重要作用,加深学生对基因概念及遗传规律的认识和理解,提升学生理论知识与实验技能的整合运用能力。

The cultivation of innovative abilities has become an important guide for higher education in China. Strengthening the integrated knowledge to design experiments is an effective way to improve undergraduate students’ innovative abilities. Herein we designed a comprehensive experiment for molecular genetics by utilizing a rice Ds insertion mutant identified previously in our research project. In the comprehensive experiment, we adopt the method of scientific research as the main line of teaching and take the interesting phenotype of the rice mutant as the breakthrough point to reform and innovate genetics laboratory teaching. On the basis of this, we combined the progressive teaching method and guided the students to learn the TAIL-PCR skill and conduct an innovative experiment through expanding their knowledge. The comprehensive experiment will deepen students’ understandings of the relationship between genotypes and phenotypes, help them master the effective way of thinking and technologies for scientific research to further improve their ability of the integrated application capability of theory and practices.
