摘　　要：目的评估职业卫生学综合现场实验教学中存在的问题,把握微课开发利用的动因与方向,为引入微课教学提供依据。方法2019年5—10月选取北京大学医学部2015级七年制预防医学专业83名学生为研究对象,采用教师观察法和学生问卷调查进行研究。结果回收有效问卷77份。职业卫生学综合现场实验教学中存在“对现场调查工作的全局认识不够充足”“职业卫生相关研究工作介绍不多”“容易遗忘前次课程内容”等问题。66.2%的学生希望将微课应用于职业卫生学综合现场实验教学中。学生希望制作成微课的课程内容有职业卫生调查工作示教(84.4%)、仪器使用与操作方法(77.9%)、综合性实验涉及的知识框架与要点(64.9%);学生希望的微课组织结构包括知识内容条理呈现(90.9%)、操作内容视频呈现(88.3%)、教学总结(61.0%)、教学导入(55.8%)、思考题(40.3%);最受学生喜欢的授课方式是微信公众号。结论职业卫生学综合现场实验教学中过程中仍存在诸多不足,微课是实验课程良好的补充教学方式。学生对于引入微课教学持支持态度,应依据学生需求有针对性设计开发微课,将其引入实验课程教学,从而提升课程教学效果。Objective To assess the problems in the comprehensive field experimental teaching of occupational hygiene,grasp the motivation and direction of the development and utilization of Micro-lesson,and provide a basis for the introduction of Micro-lesson teaching.Methods Eighty-three students majoring in preventive medicine of the seven-year program of Grade 2015 in Peking University Health Science Center from May to October in 2019 were selected as subjects.Teacher observation method and student questionnaire survey were used to conduct the research.Results 77 valid questionnaires were recovered.In the comprehensive field experimental teaching of occupational hygiene,there were problems such as"the overall understanding of the field investigation work was not enough","the introduction of occupational health-related research work was not much","it was easy to forget the content of the previous course".66.2%of students hoped to apply Micro-lessons to the comprehensive field experimental teaching of occupational hygiene.The content of the courses students hoped to make into Micro-lessons including occupational health survey teaching(84.4%),method of instrument use and operation(77.9%),and the knowledge framework and main points involved in comprehensive experiments(64.9%).The organization structure of Micro-lessons included presentation of knowledge content(90.9%),operation content video presentation(88.3%),teaching summary(61.0%),teaching introduction(55.8%),and thinking questions(40.3%).Besides,WeChat public account was the most popular teaching method among students.Conclusions There are still many deficiencies in the comprehensive field experimental teaching of occupational hygiene.Micro-lesson is a good supplementary teaching method.Students have a supportive attitude towards the introduction of Micro-lesson teaching,and it should be designed and developed to meet the learning needs of students and introduce them into experimental class teaching,improving the quality and effect of course teaching.
