摘要:
目的:结合专业培养目标和用人单位要求,探讨预防医学本科专业核心课《生物医学实验》课程项目的合理设置,为改革《生物医学实验》课程教学项目提出建议。方法:对医疗机构和高校的工作人员采用问卷调查法和访谈法,就课程是否需要更新、评分情况以及改进建议等问题进行调查,并进行统计分析。结果:本次调查共收集98份有问卷,83.67% (82/98)表示不需要更新;对不同项目的评分进行秩和检验,结果显示S9制备——公共场所(宾馆)空气中微生物采样方法(虚拟仿真实验)两者评分差异具有统计学意义(P Objective: To explore the reasonable setting of the core course “Biomedical Experiment” for undergraduate preventive medicine majors in combination with the training objectives of the major and the requirements of employers, and to put forward suggestions for the reform of the teaching project of “Biomedical Experiment”. Methods: The staff of medical institutions and universities were investigated by questionnaire and interview, and the questions about whether the curriculum needs to be updated, the scoring situation and the improvement suggestions were analyzed statistically. Results: A total of 98 questionnaires were collected in this survey, and 83.67% (82/98) indicated that there was no need to update them. The rank sum test was conducted for the scores of different items, and the results showed that the scores of S9 preparation-sampling method of microorganisms in the air of public places (hotels) (virtual simulation experiment) had statistical significance (P < 0.05), and the scores of S9 courses were lower. The rank sum test results of different unit types showed that there were statistically significant differences in the distribution of basic manipulation techniques of experimental animals, oral acute toxicity determination of Dimethoate, LD50 calculation, micronucleus test of mouse bone marrow polychromic erythrocytes, chromosome preparation of mouse bone marrow cells, sperm malformation test and toxicology experiment design among centers for Disease Control and Prevention and universities (P < 0.05). Among them, universities scored higher than other units. Conclusion: At present, the setting of “Biomedical Curriculum” is reasonable, and all units give high marks to it. The S9 experimental method may need to be optimiz
