综合性实验教学是职业卫生学不可或缺的一部分,是提升学生实验操作能力及专业素质的有效途径。本文阐述了虚实结合教学方法在职业卫生学综合性实验教学中的设计与实施,并于2022年4月,选取北京大学2018级预防医学专业72名学生为研究对象,采用教师观察、学生访谈和学生问卷调查,对教学效果进行评价。结果显示,70名(97.2%)学生认为学习虚拟仿真实验有所收获;59名(81.9%)学生对虚实结合综合性实验课程表示满意;58名(80.6%)学生认为自身职业卫生技能有所提升。可见,在职业卫生学综合性实验教学中采用虚实结合教学方法,有助于提高学生职业卫生技能并取得良好的教学满意度,虚实结合教学方法值得进一步探索和完善。
Comprehensive experimental teaching is an indispensable part of occupational hygiene and an effective way to improve students' experimental operation ability and professional quality. This paper expounds the design and implementation of virtual-real combination teaching method in the comprehensive experimental teaching of occupational hygiene. In April 2022,72 students majoring in Preventive Medicine enrolled in 2018 at Peking University who participated in the course were selected as the research subjects. Teaching effectiveness was evaluated through teacher observation, student interviews, and student questionnaire surveys.The results show that 70(97.2%) students thought that learning virtual simulation experiment was rewarding, 59 students (81.9%) expressed satisfaction with the comprehensive experimental course with the virtual-real combination, 58(80.6%) students believed that their occupational health skills are improved. Obviously, the virtual-real combination teaching methods in comprehensive experimental teaching of occupational hygiene can improve students' occupational health skills and achieve good teaching satisfaction, which is worth further exploration and improvement.
