仿真塑胶细菌培养物在“医学微生物学实验”教学中的应用

Application of simulated plastic bacterial cultures in the teaching of Medical Microbiology Experiment

摘要:

医学微生物学实验是医学院校不可缺少的基础必修课，也是涉及实验室生物安全的特殊课程。为杜绝生物安全隐患，避免实验结果不稳定及生化反应现象不典型的问题，将医学微生物实验中示教的典型细菌培养物和细菌的生化反应结果制成仿真塑胶教具，并应用于实验教学，对实验组与对照组学生的实验考核和问卷调查结果进行统计分析。结果表明仿真塑胶教具仿真度较高，示教观察点能达到教学要求，学生和教师对仿真教具的接受度高，试点班应用后学生考核成绩略高于对照组，达到预期的教学效果。细菌培养物仿真塑胶教具有很好的应用价值。

Abstract:

Medical Microbiology Experiment is a compulsory course in medical universities and colleges, which concerns laboratory biosafety. In order to eliminate hidden dangers over biosafety and avoid problems such as unstable results caused by experiments and atypical biochemical reactions, we have made simulated plastic molds of the typical bacterial cultures and biochemical reaction outcomes of microbiology and have applied them to the experiment teaching. The experiment examination and questionnaire survey results of students were compared between the experiment group and the control group. The results showed that the plastic teaching aids had high simulation degree and met the requirements of observation points in teaching, and students and teachers had high acceptance of the teaching aids. The assessment score of students in the pilot class with application of the teaching aids was slightly higher than that of students in the control class, which indicated the teaching performance as expected. In a word, the simulated teaching aids can guarantee the teaching quality and has a good prospect in the future.
