口腔虚拟仿真MOEC的“五段”式线上实践教学的探索与实践

目的:探讨口腔虚拟仿真MOEC的“五段”式线上实践教学的教学效果。方法:选取我校口腔医学专业210名学生为研究对象,分为两组,其中实验组99名学生,采用口腔虚拟仿真MOEC的“五段”式线上实践教学法进行线上授课,即学习通预习奠定基础、思维导图理清思路、钉钉直播讲授重点、口腔虚拟仿真MOEC操作训练和线下替代训练寻技巧;对照组111名学生,采用“学习通+钉钉直播”模式进行线上授课。授课结束后,选取国家口腔执业医师实践技能考试项目(二类洞制备、上下牙列印模制取、下牙槽神经阻滞麻醉和牙体制备),采用主观、客观相结合的方式,根据评分标准进行技能考核作为客观评价,结合学生调查问卷作为主观评价,评价口腔虚拟仿真MOEC的“五段”式线上实践教学的教学效果。结果:客观评价方面,实验组学生二类洞制备、上下牙列印模制取、下牙槽神经阻滞麻醉和牙体预备的考核成绩均高于对照组学生(P均<0.01);主观评价方面,实验组学生课堂的满意度、学习兴趣和主动性、技能操作、临床思维能力以及知识掌握持久性等方面均高于对照组(P均<0.01)。结论:采用口腔虚拟仿真MOEC的“五段”式线上实践教学能够保证线上授课质量,改善线上实践教学实验器材缺少的困境,提升学生自主学习能力,对培养创新型人才发挥着重要作用,值得在口腔专业的实践教学中进一步的推广及应用。

Simulation of the western North Pacific subtropical high in El Ni?o decaying summers by CMIP5 AGCMs

The performances of CMIP5 atmospheric general circulation models （AGCMs） in simulating the western North Pacific subtropical high （WNPSH） in El Nino decaying summers are examined in this study. Results show that most models can reproduce the spatial pattern of both climatological and anomalous circulation associated with the WNPSH in El Nino decaying summers. Most CMIP5 AGCMs can capture the westward shift of the WNPSH in El Nino decaying summers compared with the climatological location. With respect to the sub-seasonal variation of the WNPSH, the performances of these AGCMs in reproducing the northward jump of the WNPSH are better than simulating the eastward retreat of the WNPSH from July to August. Twenty-one out of twenty-two （20 out of 22） models can reasonably reproduce the northward jump of the WNPSH in El Nino decaying summers （climatology）, while only 7 out of 22 （8 out of 22） AGCMs can reasonably reproduce the eastward retreat of the WNPSH in El Nino decaying summers （climatology）. In addition, there is a close connection between the climatological WNPSH location bias and that in El Nino decaying summers.
