本科生助教模式在微生物学实验教学中的探索与实践

Exploration and practice of undergraduate assistant mode in the teaching of Microbiology Experiment

微生物学是水产养殖专业的一门重要的专业课,其实验教学则是将理论知识转化为实践能力的重要途径,在专业人才培养中占据重要地位。由于微生物学实验具有操作过程烦琐、耗时较长等特点,在有限的课时内,学生无法经历每一个实验步骤,系统完成全部实验过程,教学效果往往不尽如人意。本文将本科生助教模式应用于微生物学实验教学中,让助教利用碎片化的时间进入实验室,参与实验设计、试剂和培养基配制、微生物分离和纯化等工作,掌握较扎实的实验技能,然后回到课堂,充当师生沟通的桥梁,协助教师指导学生实验。助教的学习兴趣和综合素质得以提高,学生在实验中的错误得到及时纠正,教学效果也得到提升。

Microbiology is an important professional course for the aquaculture major.The experiment teaching of Microbiology is a key approach to convert theoretical knowledge into practical ability,which plays an essential role in the training of professional personnel.However,the operation of microbiological experiment is complicated and time-consuming.In the limited experimental teaching time,students cannot systematically participate in the complete experimental process,which results in the unsatisfactory teaching effect.We have explored the mode of undergraduate assistant in the teaching of Microbiology Experiment.The teaching assistants used their fragmented time to participate in experimental design,preparation of reagents and media,isolation and purification of microorganisms and mastered strong experimental skills.Then,they went back to the classroom to act as a bridge between teachers and students,assisting teachers to guide students’experiments.This mode enhanced the learning interest and comprehensive quality of the assistants,corrected the students’mistakes during the experiment in time,and improved the teaching effect.
