微课在正畸活动矫治器实习课中的应用效果评价

Evaluation of application effect of micro-class in orthodontic removable appliance practicum

目的 探讨微课在五年制15I腔本科学生正畸实习课中的应用效果。方法 选取中国医科大学口腔医学本科2012级和2011级学生作为研究对象，进行正畸活动矫治器制作的实习课教学。其中50名2012级学生作为实验组以微课形式进行示教，70名2011级学生作为对照组以传统形式教学。通过问卷调查的方式进行教学效果评价和满意度调查。应用SPSS 21．0行独立样本t检验和卡方检验。结果 问卷调查显示：实验组在激发学习兴趣、提高学习效率、对课程的支持及满意情况方面的评分均优于对照组f（4．00±0．73）VS．（3．05±0．77）；（4．06±0．65）VS．（3．06±1．01）；（4．86±0．35）vs．（2．64±0．80）；（4．32±0．47）vs．（2．62±1．08）1，差异均具有统计学意义（P〈0．01）。结论 微课能较好地达到正畸活动矫治器实习课的教学效果，值得推广。

Objective To investigate the effect of Micro-class in orthodontic practicum for five-year undergraduate students in stomotology. Methods Experimental comparative method was used on two groups of undergraduate students. A total of 70 students in Grade 2011 were taught with traditional teaching mode as the control group, while 50 students in Grade 2012 were taught with Micro-class lecture as the observation group. The satisfaction questionnaires were distributed to both groups after the course to facilitate the eval- uation of teaching methods, which specifically was done by SPSS 21.0 for t test and Chi-square test. Results The results of survey showed that the satisfaction of the observation group was significantly higher than that of the control group, which exemplified in the studying interest inspiration, studying efficiency improvement, further development, and overall satisfaction [（4.00 ± 0.73） vs. （3.05 ± 0.77）; （4.06 ± 0.65） vs. （3.06±1.01）; （4.86 ± 0.35） vs. （2.64 ± 0.80）; （4.32 ± 0.47） vs. （2.62 ± 1.08）], （P〈0.01）. Conclusion Micro-class can improve the teaching quality, and it is meaningful to apply the micro-class in orthodontic practicum.
