The research and practice for the teaching reform of the comprehensive experiment of Microbiology “Screening of the halophilic actinomycetes producing cellulose”

摘要:

微生物学实验技术是现代生物技术的重要组成部分。以综合性实验“产纤维素酶的嗜盐放线菌筛选”的教学改革与实践为例,提高南疆少数民族生物技术专业学生的综合素质。在喀什大学现有生物实验教学条件下,通过开展“产纤维素酶的嗜盐放线菌筛选”的综合性实验,进行微生物学实验课教学模式改革。在“土壤微生物分离”验证性实验的基础上,增加“嗜盐放线菌筛选和产纤维素特性”的实验教学内容;运用多媒体课件、增加实验理论课和全程采用“启发式”教学的实验教学方法。问卷调查显示,学生在学习兴趣、学习主动性、实验技能、小组合作、探究精神和实验设计方面都有了明显进步;学生对实验教学改革的评价良好。实践证明,改革效果良好,对培养具备适应南疆社会发展的实践能力的复合型高级专门人才有积极显著的作用。

Abstract:

Experimental techniques of microbiology are the important part of modern biotechnology. The purpose of the research and practice for the teaching reform of the comprehensive experiment of microbiology was to improve the overall qualities of ethnic minority students specialized in biotechnology in south part of Xinjiang Uygur Autonomous Region. The experimental content was changed to the comprehensive experiment “screening of halophilic actinomycetes producing cellulase” from the basic experiment “screening of soil microorganism”. These teaching methods were employed according to the existing teaching conditions, such as, applying the heuristic teaching and the multimedia courseware, adding the theoretical courses of the microbiological experiments, etc. The surveys showed that the practice of teaching reform stimulated the students' interests in learning, enhanced students' learning initiative and developed the practical skills, the teamwork skills, the exploring skills and the capabilities of experimental design for the students. The students believed that the teaching reform achieved the good results. It is proved in practice that teaching reform had the positive effects to cultivate the inter-disciplinary talents who could meet the need of the social development in Xinjiang.
