虚拟仿真“第二课堂”在卫生化学教学改革中的应用探索

The Application of the“Second Classroom”of Virtual Simulation to Teaching Reform of Sanitary Chemistry Course

以《卫生化学》课程为例,探索、评价和分析虚拟仿真在卫生检验与检疫专业“第二课堂”中的应用效果。将虚拟仿真实验应用于“第二课堂”,构建虚拟仿真“第二课堂”,对2017级卫生检验与检疫专业学生进行教学实践,采用问卷调查对教学效果进行评价。问卷调查结果显示,学生对虚拟仿真“第二课堂”总体认同率为92.2%,说明学生对该教学活动充分肯定,该教学实践较为成功。该教学模式丰富了“第二课堂”的内容,有效拓展了课堂教学,对学生的专业实践能力和创新思维能力的培养具有重要的促进作用。

Taking sanitary chemistry course of health inspection and quarantine specialty as an example,the“second classroom”of virtual simulation was explored,evaluated and analyzed.The virtual simulation experiment was applied to the“second classroom”to construct the“second classroom of virtual simulation practice”.The teaching mode was practised on the students of health inspection and quarantine major of grade 2017.The teaching effect was evaluated by questionnaire survey.The results of the questionnaire survey show that the overall identification rate of the students to the“second classroom”of virtual simulation was 92.2%,which indicated that the majority of students approved the teaching mode and the teaching practice was successful.This teaching mode enriches the content of“the second classroom”,effectively expands the classroom teaching,playing an important role in promoting the cultivation of students'professional practice ability and innovative thinking ability.
